12.12 : 评估脉搏时的特殊考虑

Some unexpected situations that arise while assessing a pulse include the pulse becoming irregular, disappearing, or being absent.

In an irregular pulse scenario, assess the pulse for one full minute.

If a pulse is felt but disappears, refrain from applying pressure as it suppresses the pulse.

To ensure accuracy, note the pulse location and mark it with an X.

The absence of a pulse indicates a failure to feel the pulse.

To assess a pulse accurately, the following are certain general criteria that must be considered.

An ultrasound Doppler helps accurately record a pulse's presence or absence.

Notify the physician if there is an incidence of an absence or irregular pulse.

The range of pulse varies with age.

For children younger than two, auscultate the apical pulse, as arteries lie superficial to the skin and can diminish easily.

The apical pulse is assessed for a full minute and is assessed in patients with congenital and acquired cardiac conditions.

Additionally, an apical pulse assessment is indicated if an irregular, feeble, or extremely rapid peripheral pulse is identified.
