The blindfolded code exercise consists of several critical steps. First, the exercise requires an initial faculty demonstration to decrease the learners&#8217; intimidation and anxiety toward performing a resuscitation blindfolded. It also serves to give learners an example of a successful performance of the blindfolded resuscitation. Facing the code team leader away from the resuscitation team ensures that the leader is unable to visualize the scenario and forces them to give loud, clear orders (Fig...

The blindfolded code training exercise was developed to improve closed-loop communication, the utilization of a conceptual framework to organize the management of a resuscitation, and critical thinking skills. Previous scholars reported that communication, role clarity, and teamwork were enhanced by blindfolding physicians during simulated resuscitations1. Resident physicians, especially in critical care specialties, are frequently placed in high-acuity situations. In order to appropriately manage these high-risk cases, resident physicians require training in both leadership strategies and communication in high-risk environments2,3. Simulation is commonly used and is effective in teaching crisis resource management principles and communication skills4.&#160;
Currently, there is limited knowledge of innovative techniques to improve resident physician communication and leadership strategies in high-acuity situations. Ineffective communication may continue despite correct management and leadership observed in the simulation lab. A previous study highlights that the blindfolded code training exercise, when compared to typical code training, is more challenging and forces learners to use critical thinking skills and closed-loop communication. Learners felt the exercise solidified leadership skills and challenged them to maintain mental organization without visual cues5.&#160;
In preparation for the blindfolded code training exercise, the faculty provides a demonstration explaining how this advanced approach is performed, to decrease learner intimidation by the exercise. Once the demonstration is finished, the team leader is blindfolded. The team leader must use closed-loop communication and give explicit orders to the resuscitation team with a request to have all orders repeated back. The team cannot independently initiate any procedure or management without clear direction from the team leader. Team members can only execute orders from the team leader that are explicitly directed to them by name. If the team leader does not identify a specific person to perform the action, it is not performed. For example, if the team leader states, &#8220;Start compressions&#8221; without directing it to a specific team member, the order is not completed. All members of the team stand motionless. If a team member is given an order by the leader but is not requested to repeat the order as confirmation, the order can be executed but the team leader is not given verbal feedback at the completion of the order. This should prompt the team leader to ask that subsequent orders are to be repeated back, as the leader does not have visual stimuli to confirm order completion.&#160;
If the team leader asks team members to repeat the orders back, team members must reply to the team leader using closed-loop communication. This alerts the team leader when the order is received and completed. For example, if team leader Dr. Jones asks John to &#8220;Give 1 mg of epinephrine intravenously&#8221;, John will reply &#8220;I will get 1 mg of epinephrine. Dr. Jones, 1 mg of epinephrine has been administered intravenously&#8221;. The team leader can ask questions about the monitor. However, team members can only describe the appearance of the cardiac rhythm in layman&#8217;s terms (Table 1). For example, ventricular tachycardia would be described as a wide complex regular rhythm at the rate displayed on the monitor. Team members cannot use medical terms when describing the cardiac monitor, such as ventricular tachycardia or pulseless electrical activity. Lastly, faculty will verbally clarify all physical exam findings if the code team leader directs a team member to perform a physical exam.
By removing visual stimuli, the blindfolded code training exercise forces the team leader to maintain mental organization and use closed-loop communication to effectively manage a resuscitation. The purpose of the description of the blindfolded code training exercise is to provide guidance on how to perform this innovative teaching technique to force closed-loop communication.

setup and execution of the blindfolded code training exercise

Miscommunication is the most common cause of preventable patient harm in medicine. Currently, there is limited knowledge of innovative techniques to improve resident physician communication and leadership strategies in high-acuity situations. The blindfolded code training exercise removes visual stimuli from the team leader, forcing the team leader to effectively utilize closed-loop communication. The simple act of blindfolding the team leader creates a learning environment where the leader must utilize a conceptual framework and critical thinking strategies to organize the team and manage the resuscitation. An advantage to this teaching technique is that it does not require any special simulation equipment, making it a low-cost approach. The blindfolded code training exercise can be applied to the management of any critically ill patient where the primary objective is to focus on developing communication skills in acute resuscitations. The purpose of the description of the blindfolded code training exercise is to provide guidance on how to perform this innovative teaching technique to force effective closed-loop communication.

As noted in Ahmed et al., all residents (100%, 27/27) agreed/strongly agreed that knowledge obtained during the blindfolded code training exercise could be transferred to the clinical setting5. In addition, most residents strongly agreed that the blindfolded code training exercise was more challenging (81.5%, 22/27), allowed them to apply critical thinking skills (81.5%, 22/27), and improved use closed-loop communication (88.9%, 24/27) when compared to typical code training exercises (Tabl...

Communication errors are the leading cause of preventable patient harm in all of medicine. The blindfolded code training technique was designed to improve closed-loop communication and improve critical thinking in high-acuity situations. The main advantage of this teaching technique is that it teaches resident physicians effective communication and leadership strategies in a high-acuity situation without requiring any special equipment.Before beginning the blindfolded code training exercise, gather all of the necessary supplies and materials and place the human patient simulator on an Emergency Department bed. Turn on the simulator and connect the simulator to the wireless network. Provide a seat five feet away from the foot of the bed and a blindfold for the code team leader.Then seat the team leader facing away from the team. Print code resuscitation simulation scenarios for the faculty and upload any necessary radiographic images and electrocardiograms for each patient scenario. Before beginning the exercise, review the rules with the learners and have the team leader put on the blindfold.Have the resuscitation team members verbally introduce themselves by role, name and position in relation to the patient in the bed to the blindfolded code team leader. I'm Patrick, I'm the med student, and I'm at the patient's right of the bed. I'm Edgar, I'm the emergency medicine resident, and I'll be at the head of the bed.I'm Pat, I'm your nurse, I'm at the patient's left side of the bed and can administer medications. I'm Kate, I'm your senior resident, I'm at the left of the bed. When all of the team members have introduced themselves, read the stem for the case scenario to the code team leader and change the patient vitals and cardiac rhythms in alignment with the case scenario outline.Then run the case scenario for eight to 10 minutes. Hi everyone, my name is Lauren. I'll be your team leader.Please repeat all orders back in a closed-loop fashion. Does everyone understand? Yes.All right, Edgar, what does our patient look like?So it's a middle-aged man. He's unresponsive and has no respiratory effort. Okay, what rhythm do I see on the monitor?You see a Y complex, irregular rhythm, without discernible P, QRS, or T waves. Okay, that sounds like V-fib. Pat, do you feel a pulse?I do not. Okay, Kate, please start chest compressions. Starting chest compressions.All right, Patrick, please charge our defibrillator up to 200 joules. Turning on and charging the defibrillator to 200 joules. Okay, Edgar, please start bagging our patient at a rate of two breaths for every 30 compressions.All right, I'll start bagging the patient two breaths for every 30 compressions. Defibrillator is charged to 200 joules. Okay, Kate, please pause chest compressions.Stopping chest compressions. Deliver one shock, Patrick, please. Shock delivered.Okay, Kate, continue chest compressions. Resuming chest compressions. All right, Edgar at our next pulse check, I'm going to ask you to intubate our patient.All right, I'll prepare supplies to intubate the patient at the next pulse check. All right, Pat, could you please draw up one milligram of epinephrine? Drawing up one milligram of epinephrine.And please deliver that when ready. Okay, one milligram epinephrine drawn up. One milligram of epinephrine given to the patient.Okay.Edgar, how much time has passed since our last pulse check? It's been 90 seconds since our last pulse check. Edgar, can you please let me know when two minutes have passed.I will let you know when two minutes have passed. At the conclusion of the case scenario, debrief the code team for approximately 10 minutes, focusing on the utilization of closed-loop communication, the leader's effectiveness in leading the resuscitation, and the management decisions as they relate to the advanced cardiac life support or advanced trauma life support algorithms. Then select another code team leader and repeat the process at the conclusion of the debriefing.In this representative study, 100%of residents agreed or strongly agreed that the knowledge obtained during the blindfolded code training exercise could be transferred to the clinical setting. Most residents strongly agreed that the blindfolded code training exercise was more challenging, allowed them to apply critical thinking skills, and improved the use of closed-loop communication compared to typical code training exercises. Residents also felt that maintaining mental organization without visual cues was the most challenging part of this exercise.It's important to review the rules with the learners before beginning the simulation and have all team members introduce themselves to the blindfolded code team leader. This innovative teaching technique can be applied to the management of any critically ill patient with the focus on developing more effective communication strategies in high-risk environments. Future directions for this study include utilizing validated assessment tools to evaluate teamwork, communication and leadership when comparing blindfolded to nonblindfolded team leaders in high-acuity situations.

Determining The Electromyographic Fatigue Threshold Following a Single Visit Exercise Test

Theoretically, the electromyographic (EMG) fatigue threshold is the exercise intensity an individual can maintain indefinitely without the need to recruit more motor units which is associated with an increase in the EMG amplitude. Although different protocols have been used to estimate the EMG fatigue threshold they require multiple visits which are impractical for a clinical setting. Here, we present a protocol for estimating the EMG fatigue threshold for cycle ergometry which requires a single visit. This protocol is simple, convenient, and completed within 15-20 min, therefore, has the potential to be translated into a tool that clinicians can use in exercise prescription.

This protocol describes the electromyographic fatigue threshold which demarcates between nonfatiguing and fatiguing exercise workloads. This information could be used to develop a more individualized training program.

Ultrasound Assessment of Endothelial Function: A Technical Guideline of the Flow-mediated Dilation Test

Cardiovascular disease is the primary cause of mortality and a major cause of disability worldwide. The dysfunction of the vascular endothelium is a pathological condition characterized mainly by a disruption in the balance between vasodilator and vasoconstrictor substances and is proposed to play an important role in the development of atherosclerotic cardiovascular disease. Therefore, a precise evaluation of endothelial function in humans represents an important tool that could help better understand the etiology of multiple cardio-centric pathologies.
Over the past twenty-five years, many methodological approaches have been developed to provide an assessment of endothelial function in humans. Introduced in 1989, the FMD test incorporates a forearm occlusion and subsequent reactive hyperemia that promotes nitric oxide production and vasodilation of the brachial artery. The FMD test is now the most widely utilized, non-invasive, ultrasonic assessment of endothelial function in humans and has been associated with future cardiovascular events.
Although the FMD test could have clinical utility, it is a physiological assessment that has inherited several confounding factors that need to be considered. This article describes a standardized protocol for determining FMD including the recommended methodology to help minimize the physiological and technical issues and improve the precision and reproducibility of the assessment.

The flow mediated dilation (FMD) test is the most commonly utilized, non-invasive, ultrasound assessment of endothelial function in humans.

Induction and Assessment of Exertional Skeletal Muscle Damage in Humans

Contraction-induced muscle damage via voluntary eccentric (lengthening) contractions offers an excellent model for studying muscle adaptation and recovery in humans. Herein we discuss the design of an eccentric exercise protocol to induce damage in the quadriceps muscles, marked by changes in strength, soreness, and plasma creatine kinase levels. This method is simple, ethical, and widely applicable since it is performed in human participants and eliminates the interspecies translation of the results. Subjects perform 300 maximal eccentric contractions of the knee extensor muscles at a speed of 120&#176;/sec on an isokinetic dynamometer. The extent of the damage is measurable using relatively non-invasive isokinetic and isometric measures of strength loss, soreness, and plasma creatine kinase levels over several days following the exercise. Therefore, its application can be directed to specific populations in an attempt to identify mechanisms for muscle adaptation and regeneration.

This article describes a safe and reliable method to induce and quantify exertional skeletal muscle damage in human subjects.

'Boden Food Plate': Novel Interactive Web-based Method for the Assessment of Dietary Intake

Different methods can be used in research to assess dietary intake, many of which are still paper-based. Written estimated food diaries are often utilized in clinical trials, despite being a burden for both study participants and researchers. This method requires participant literacy, it is time consuming, labor intensive, and can easily lead to under-reporting. With advancements in technology, there is a growing interest in electronic diaries that automate the dietary assessment process. These are focused on improving accuracy, reducing both time and cost and providing users with a visual and more enjoyable experience. The methodology presented here aimed to validate the &#39;Boden Food Plate&#39;, a novel web-based platform for self-recording of food and drink items, compared to a traditional estimated food diary. The application was also rated on a satisfaction scale by study participants using a paper-based questionnaire. Sixty-seven participants completed the dietary measures on both the three-day electronic and paper food diaries. For the analysis, only dietary data completed at both study time points (baseline and week six) was utilized. Despite small mean differences between dietary data collection methods, Bland Altman analysis showed fairly wide 95% limits of agreement between the electronic platform and the written estimated food diary and there were few cases which did not fall within the 95% confidence intervals. Overall, participants found the electronic food diary to be more fun than the paper method and as easy to use as hard copy diaries. The new platform has potential as a self-recording tool for the collection of dietary data, particularly when utilized in clinical trial settings. However, further validation studies are needed to improve the validity of this novel electronic dietary data collection tool.

Conducting Maximal and Submaximal Endurance Exercise Testing to Measure Physiological and Biological Responses to Acute Exercise in Humans

Regular physical activity has a positive effect on human health, but the mechanisms controlling these effects remain unclear. The physiologic and biologic responses to acute exercise are predominantly influenced by the duration and intensity of the exercise regimen. As exercise is increasingly thought of as a therapeutic treatment and/or diagnostic tool, it is important that standardizable methodologies be utilized to understand the variability and to increase the reproducibility of exercise outputs and measurements of responses to such regimens. To that end, we describe two different cycling exercise regimens that yield different physiologic outputs. In a maximal exercise test, exercise intensity is continually increased with a greater workload resulting in an increasing cardiopulmonary and metabolic response (heart rate, stroke volume, ventilation, oxygen consumption and carbon dioxide production). In contrast, during endurance exercise tests, the demand is increased from that at rest, but is raised to a fixed submaximal exercise intensity resulting in a cardiopulmonary and metabolic response that typically plateaus. Along with the protocols, we provide suggestions on measuring physiologic outputs that include, but are not limited to, heart rate, slow and forced vital capacity, gas exchange metrics, and blood pressure to enable the comparison of exercise outputs between studies. Biospecimens can then be sampled to assess cellular, protein, and/or gene expression responses. Overall, this approach can be easily adapted into both short- and long-term effects of two distinct exercise regimens.

To assess the influence of exercise intensity on physiologic and biologic responses, two different exercise testing protocols were utilized. Methods outlining exercise testing on a cycle ergometer as an incremental maximal oxygen consumption test and endurance, steady state submaximal endurance test are described.

Transaxillary First Rib Resection for Treatment of the Thoracic Outlet Syndrome

Thoracic outlet syndrome (TOS) is a common disorder that causes a significant loss of productivity. The transaxillary first rib resection (TFRR) protocol has been used for the decompression of trapped neurovascular structures in the TOS. Among the other surgical procedures, the advantage of the TFRR is that it has the smallest rate of recurrence and better cosmetic outcomes. The disadvantage of TFRR is that it provides a narrow, and deep working corridor that makes obtaining vascular control challenging.

Here, we present a protocol of the transaxillary resection of the first rib for treatment of thoracic outlet syndrome caused by compression of the brachial plexus, subclavian vein and artery.

Setup and Execution of the Rapid Cycle Deliberate Practice Death Notification Curriculum

Death notification is an important and challenging aspect of Emergency Medicine. An Emergency Medicine physician must deliver bad news, often sudden and unexpected, to patients and family members without any previous relationship. Unskilled death notification after unexpected events can lead to the development of pathologic grief and posttraumatic stress disorder. It is paramount for Emergency Medicine physicians to be trained in and practice death notification techniques. The GRIEV_ING curriculum provides a conceptual framework for death notification. The curriculum has demonstrated improvement in learners&#8217; confidence and competence when delivering bad news. Rapid Cycle Deliberate Practice is a simulation-based medical education technique that uses within the scenario debriefing. This technique uses the concepts of mastery learning and deliberate practice. It allows educators to pause a scenario, provide directed feedback, and then let learners continue the simulation scenario the &#8220;right way.&#8221; The purpose of this scholarly work is to describe how to apply the Rapid Cycle Deliberate Practice debriefing technique to the GRIEV_ING death notification curriculum to more effectively train learners in the delivery of bad news.

The goal is to demonstrate how to apply the rapid cycle deliberate practice debriefing technique to the GRIEV_ING death notification curriculum.

A Real-World High-Intensity Interval Training Protocol for Cardiorespiratory Fitness Improvement

High-Intensity Interval Training (HIIT) has emerged as an interesting time-efficient approach to increase exercise adherence and improve health. However, few studies have tested the efficiency of HIIT protocols in a &#34;real world&#34; setting, e.g., HIIT protocols designed for outdoor spaces without specialized equipment. This study presents a &#34;real world&#34; training protocol, named &#34;beep training&#34;, and compares the efficiency of a HIIT regiment versus a traditional long-duration Moderate-Intensity Continuous Training (MICT) regiment using this beep training protocol on VO2 max of overweight untrained men. Twenty-two subjects performed outdoor running with MICT (n = 11) or HIIT (n = 11). Cardiorespiratory fitness was assessed before and after training protocols using a metabolic analyzer. Both training protocols were performed 3 days a week for 8 weeks using the Beep Test results. The MICT group performed the exercise program at 60%-75% of the maximum speed of the 20 m shuttle test (Vmax) and with a progression of the distance of 3,500-5,000 m. The HIIT group performed the interval exercise with 7-10 bouts of 200 m at 85%-100% of the maximum speed of the 20 m shuttle test (Vmax), interspersed with 1 min of passive recovery. Although the HIIT group presented a significantly lower training volume than the MICT group (p &#60; 0.05) after 8 weeks of beep training, HIIT was superior to MICT in improving VO2 max (MICT: ~4.1%; HIIT: ~7.3%; p &#60; 0.05). The &#34;real world&#34; HIIT regiment based on beep training protocol is a time-efficient, low-cost, and easy-to-implement protocol for overweight untrained men.

This study presents a low-cost and easy-to-implement "real world" high-intensity interval training (HIIT) protocol for scientific research and discusses its efficiency for cardiorespiratory fitness.

Randomized Controlled Trial to Study the Acute Effects of Strength Exercise on Insulin Sensitivity in Obese Adults

An acute session of strength exercise (SE) ameliorates insulin sensitivity (IS) for several hours; however, the effects of SE volume (i.e., number of sets) have not been studied thoroughly. Although it is intuitive that some SE is better than none, and more is better than some for the improvement of IS, high-volume sessions might be challenging for diseased populations to complete, especially obese adults, for whom even a brisk walk can be challenging. This protocol details a randomized clinical trial to assess the acute effects of SE on IS in obese adults. The inclusion criteria are body mass index &#62;30 kg/m2, central obesity (waist circumference &#62;88 cm and &#62;102 cm for women and men, respectively), and age &#62;40 years. Participants will be familiarized with the SE (7 exercises targeting major muscle groups) and then will perform three sessions in a randomized order: session 1 - high-volume session (3 sets/exercise); session 2 - low-volume session (1 set/exercise); session 3 - control session (no exercise). Diet will be controlled the day before and on the day of the sessions. Sessions will be completed at night, and an oral glucose tolerance test will be performed the next morning, from which several indexes of IS will be derived, such as the area under the curve (AUC) of glucose and insulin, the Matsuda index, the Cederholm index, the muscle IS index, and the Gutt index. Based on pilot studies, we expect ~15% improvement in IS (insulin AUC, and Matsuda and Cederholm indexes) after the high-volume session, and ~8% improvement after the low-volume session compared to the control session. This study will benefit individuals who find high-volume SE sessions challenging but still aim to improve their IS by investing 1/3 of their time and effort.
