Introduction; Indications For Use; General - Respironics 920 Instruction And Service Manual

III. Introduction
A. Indications for Use
The 920 Hand Held Pulse Oximeter is intended to be used for
monitoring oxygen saturation and pulse rate for adult, pediatric, and
neonatal patients in hospital, ambulatory, home, and EMS
environments. The 920 may be used for spot checking and/or
continuous monitoring when attended by a healthcare professional. The
variety of individual sensors available must be checked frequently to
ensure proper circulation and application.
B. General
The 920 Hand Held Pulse Oximeter is small and lightweight. The
920 has visual alarms for tracking patient status. It typically will
operate for 100 hours continuously between battery replacements.
The 920 requires no routine calibration or maintenance.
The 920 determines arterial oxyhemoglobin saturation (%SpO
measuring the absorption of red and infrared light passed through
tissue. Changes in absorption caused by pulsation of blood in the
vascular bed are used to determine arterial saturation and pulse
rate.
Oxygen saturation and pulse rate are displayed on light emitting
diode (LED) digital displays. On each detected pulse, the perfusion
LED flashes. Patient perfusion signals are graded as good,
marginal or inadequate and are indicated as such by the LED
flashing green, yellow, or red. This simple method gives the user a
pulse-by-pulse visual indication of waveform signal quality without
requiring the user to perform complex waveform analysis during
critical patient care situations.
Sensor disconnect or malfunction is indicated by lack of good
perfusion flashes and/or a dash to the left of the SpO
LED display. Ultimately, if adequate perfusion pulses are not
received, the SpO and Pulse Rate (♥) numerical values will be
2
replaced by dashes. When the batteries are low, the digital displays
will blink.
The 920 Pulse Oximeter may be used with all Respironics pulse
oximeter sensors (except fiber optic sensors) enabling proper
operation for nearly every patient.
NOTE: Respironics sensors do not contain natural rubber
latex.
