Caution Users should check for audible pulse tones in conjunction with the
SpO
2
function. If these tones do not sound, the audio has failed. Remove the
device from service and contact Welch Allyn.
The loss of the audible alarm could cause a delay in a clinician learning of an alarm
condition for the following conditions: 1) hypotension or hypertension, 2) low
blood oxygen content (SpO
2
), 3) low or high pulse rate, 4) other alarm conditions
relating to the loss of monitoring of a patient (e.g., a “sensor off” condition). Such
delay could potentially result in injury to the patient.
