Pulse Oximetry Measurement
The ECG-SpO
2
TRx
+
Transceiver supports an SpO
2
sensor connection using
Fourier Artifact Suppression Technology (FAST). The FAST algorithm
overcomes many of the issues associated with traditional pulse oximetry such as
sensitivity to patient movement and intense ambient light. The algorithm offers
improved motion artifact rejection as well as performance improvements for
patients with low perfusion. SpO
2
can be measured continuously, where a value
is sent to the Information Center every second, or as a single, individual
measurement (Spot Check). The Spot Check measurement will be removed
from the Information Center display after 1 hour. If 1-minute or 5-minute
sampling rate is selected at TeleMon, the transceiver will provide Continuous
SpO
2
measurement after disconnection (see “Transceiver Operation when
Connected to TeleMon” on page 9-19).
The SpO
2
parameter measures the arterial oxygen saturation, that is, the
percentage of oxygenated hemoglobin in relation to the total hemoglobin.
If, for example, a total of 97% of the hemoglobin molecules in the red blood
cells of the arterial blood combine with oxygen, then the blood has an oxygen
saturation of 97%. The SpO
2
numeric that appears on the monitor will read
97%. The SpO
2
numeric indicates the percentage of hemoglobin molecules
which have combined with oxygen molecules to form oxyhemoglobin.
•
The oxygen saturation is measured using the pulse oximetry method. This
is a noninvasive method of measuring the arterial hemoglobin oxygen
saturation. It measures how much light, sent from light sources on one
side of the sensor, travels through patient tissue (such as a finger or an
ear), to a receiver on the other side of the sensor.
