General cautions
WARNING Do not connect more than one patient to a monitor.
WARNING If the monitor is dropped or damaged, it must be thoroughly tested
by a qualified service person before it is returned to service.
WARNING Periodically check all cords and cables for damage, wear, or fraying;
replace as needed.
WARNING The monitor contains no operator-serviceable parts, other than the
replaceable paper roll.
WARNING If the battery shows any signs of damage, leakage, or cracking, it
must be replaced immediately, by a qualified service person, and only with a
battery approved by Welch Allyn.
WARNING Always recycle batteries according to local regulations. Never
dispose of batteries in refuse containers.
WARNING Do not use the monitor on patients who are linked to a heart
machine or a lung machine.
WARNING Do not use the monitor on patients who are experiencing
convulsions or tremors.
WARNING Do not use the pulse oximeter as a replacement or substitute for
ECG-based arrhythmia analysis.
Caution If the accuracy of any measurement is in doubt, verify the patient’s vital
sign by another method. If the monitor is not measuring accurately, have it
inspected by a qualified service person.
Caution Be sure that the monitor is securely located on a flat surface or properly
suspended by means of appropriate mounting equipment.
Caution Do not autoclave the monitor.
Caution Do not place cups, glasses, or other fluid containers or vessels on
the monitor.
Caution Users should check for audible alarm function every time the VSM 300
is used. During the normal power-up cycle, two audible tones are emitted
immediately after the self-test is complete. 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.
