Welch Allyn Propaq LT Vital Signs Monitor
Monitoring SpO
2
The monitor can be purchased with the Nellcor or the Masimo SpO
2
option. Most of this
chapter pertains to either configuration. Monitors with the Masimo technology, however,
can provide additional SpO
2
data. (
WARNING Accurate measurements of oxygen saturation, when derived from
pulse oximetry, depend to a great extent on patient condition and proper sensor
placement. Patient conditions such as shivering and smoke inhalation can result in
erroneous readings. If you believe a measurement might be inaccurate, verify it
using another clinically accepted measurement method, such as arterial blood gas
measurements using a co-oximeter.
WARNING Use only SpO
2
accessories listed in the accessory list or at
. Inspect sensors and cables, and discard any that are
damaged. Do not use a sensor with exposed optical components.
WARNING Use of Masimo LNOP sensors/cables will not provide protection in
accordance with IEC defibrillation standards when used with this device.
WARNING If you need to increase the length of the sensor cable, use only one
extension. Use of multiple extensions can adversely affect performance. Do not
attach any cable that is intended for computer use to the SpO
2
connector at the
monitor.
WARNING Tissue damage and erroneous measurements can be caused by
incorrect application or use of a sensor. (Examples of bad practices: wrapping the
sensor too tightly, applying supplemental tape, failing to periodically inspect the
sensor site, leaving a sensor on too long in one place.) Refer to the
manufacturer’s directions for specific instructions on application and use, and for
description, warnings, cautions, and specifications.
WARNING Do not modify the sensor.
WARNING Do not wet the sensor or immerse it in fluid. Do not attempt to
sterilize a sensor.
WARNING Sensors exposed to ambient light while not applied to a patient can
exhibit seminormal saturation readings. Be sure the sensor is securely placed on
the patient and check its application often to ensure accurate readings.
WARNING Inaccurate measurements might be caused by venous pulsations.
WARNING The pulse oximeter can be used during defibrillation, but the
readings might be inaccurate for a short time.
WARNING Do not use the pulse oximeter as an apnea monitor.
WARNING During SpO
2
monitoring, a very sudden and substantial change in
pulse rate can result in erroneous pulse rate readings. Always validate the patient
data and patient condition before effecting an intervention or a change in patient
care.
