Pulse Oximetry
Pulse oximetry is a continuous and non-invasive measurement of the amount of oxygen
attached to the hemoglobin in red blood cells. SpO
2
is an estimation of arterial oxygen
saturation, SpO
2
may be used interchangeably with SaO

. The Passport V comes
standard with Masimo SET

are options.

Measurements
1. Select the appropriate sensor for the patient.
2. Attach the SpO
2
patient cable to the sensor and plug the other end of the patient cable
into the SpO
2
connector located on the left side panel of the monitor.
NOTE: Do not place the sensor on an extremity with an IV catheter
or blood pressure cuff in place.
3. The pleth waveform and digital SpO
2
value will be displayed by default in the second
waveform and parameter area. If desired, enter the Display Setup Menu to position
Pleth waveform and data in an alternate location.
Calibration
The oximetry sub-system incorporates automatic calibration mechanisms. No other
calibration is required.
Auto Scaling
The pleth waveform is automatically scaled and is not proportional to the patient’s pulse
volume. There is no adjustment that can be made to the pleth waveform.
CAUTION: Tissue damage or inaccurate measurements may be caused
by incorrect SpO2 sensor application or use, such as
wrapping too tightly, applying supplemental tape, failing to
inspect the sensor site periodically, or failing to position
appropriately. Carefully read the sensor directions for use,
the Passport V Operating Instructions, and all precautionary
information before use.
CAUTION: Inaccurate SpO2 measurements may be caused by:
• Incorrect sensor application or use
• Significant levels of dysfunctional hemoglobins, (e.g.,
carboxyhemoglobin or methemoglobin)
• Intra-vascular dyes such as indocyanine green or
methylene blue
• Exposure to excessive illumination such as surgical
lamps (especially ones with a xenon light source),
bilirubin lamps, fluorescent lights, infrared heating
lamps, or excessive ambient light. In such cases, cover
the sensor site with opaque material
• Excessive patient movement
• Venous pulsations
• Electro-surgical interference
