Pulse Oximetry Monitoring
5. Pulse Oximetry Monitoring
5.1. Overview of Pulse Oximetry Monitoring
Pulse oximetry monitoring works by shining light of two different wavelengths
through the patient's tissues (such as a fingertip) and measuring the absorption of
the light by the hemoglobin in the patient's arterial blood. The way the blood
absorbs the different wavelengths indicates the amount of oxygen in the blood.
Since this amount is constantly changing during each beat of pulse as new blood
comes in and old blood returns to the heart, it is also possible to detect a pulse rate
from this signal. The Nightingale PPM3 SpO
2
algorithm uses the qualified
pulsatile data averaged over a 60 second period to report the SpO
2
value.
The pulse oximetry monitoring capabilities of the Nightingale PPM3 include:
•
Measuring the functional oxygen saturation of the patient's arterial
hemoglobin (SpO
2
)
•
Calculating the patient's pulse rate (PR)
•
Displaying the pulse oximetry waveform (plethysmograph) continuously
•
Generating an audible pulse tone for each detected pulse, with the pulse
tone pitch being tied to the SpO
2
value (higher pitch used for higher SpO
2
)
5.2. Getting Started with Pulse Oximetry on the
PPM3
To begin pulse oximetry monitoring, use the following procedure:
1.
Select a sensor that is appropriate for the patient’s weight.
2. Attach the sensor to the patient per the instructions that come with the
sensor. Please refer to the Accessories chapter for a list of approved SpO
2
sensors. Clean reusable sensors before and after each use.
3. Connect the sensor cable to the SpO
2
cable on the PPM3.
Note
– See the Section 12.1.1 "ECG and Heart Rate" in the Working With Menus chapter
for information on how to display pulse rate (PR) from the SpO
2
source.
