Flashcards

Temporal Pulse Location

Pulse point located in front of the ear, superior and lateral to the eye.

Temporal Pulse Use

Used for assessing infants when radial pulse is unavailable.

Carotid Pulse Location

Pulse point located bilaterally under the lower jaw, slightly off-midline in the neck.

Carotid Pulse Use

Used in infants and during emergency situations (shock/cardiac arrest) when other pulses are weak.

Study Notes

Blood Pressure Measurement

  • Electronic sphygmomanometers measure blood pressure
  • Sites used for measurement: Arm (brachial artery), leg (popliteal artery), other sites by pupation
  • Common errors in measurement
    • Cuff is too narrow or wide
    • Arm unsupported
    • Insufficient rest before assessment
    • Cuff wrapped too loosely
    • Cuff deflated too quickly or too slowly
    • Arm above the heart level
    • Assessment immediately after meal or while patient smokes or has pain
  • Abnormal blood pressure reading (hypertension)
    • Excessive pressure on the walls of the arteries
    • Sustained systolic reading of 140 mmHg or more
    • Sustained diastolic reading of 90 mmHg or more
