P1 Patient Monitor User’s Manual
10-5
Parameters Description
a) Carboxyhemoglobin Saturation (SpCO): SpCO is a value that represents the
percentage of carboxyhemoglobin saturation within the blood.
b) Methemoglobin Saturation (SpMet): SpMet is a value that represents the percentage
of methemoglobin saturation within the blood.
c) Pleth Variability Index (PVI): PVI is a measure of peripheral perfusion changes
secondary to respiration, or the PI amplitude modulation over a respiration, and can
be closely related to intrathoracic pressure changes.
d) Total Hemoglobin (SpHb): SpHb is a measure of the total hemoglobin concentration
in arterial blood.
e) Oxygen Content (SpOC): SpOC is a measure of the total oxygen content present in
the blood.
10.5. SpO
2
Module
Accuracy confirmation of SpO
2
module measurement: SpO
2
accuracy has been
confirmed in human experiments by comparing with the reference values of arterial blood
samples measured by the blood gas analyzer.
Compared with the blood gas analyzer
measurement, the SpO
2
measurement is in accordance with the statistics distributed.
10.6. Monitoring Procedure
1. Select an appropriate sensor according to the module type, patient category
and weight.
2. Clean the contact surface of the reusable sensor.
3. Remove colored nail polish from the application site.
4. Apply the SpO
2
sensor to the patient according to the instruction for use of the
sensor.
5. Select an appropriate extension cable according to the connector type and plug
the cable into the SpO
2
connector.
6. Connect the SpO
2
sensor to the extension cable.
CAUTION:
Do not apply sensor too tightly as this results in venous pulsation which may
severely obstruct circulation and lead to inaccurate measurements.
