1.6.10.2 Special Features
Automatic Calibration
The oximetry subsystem incorporates automatic calibration mechanisms. It is automatically
calibrated each time it is turned on, at periodic intervals thereafter, and whenever a new
sensor is connected. Also, the intensity of the sensor’s LEDs is adjusted automatically to
compensate for differences in tissue thickness.
Each sensor is calibrated when manufactured; the effective mean wavelength of the red LED
is determined and encoded into a calibration resistor in the sensor plug. The instrument’s
software reads this calibration resistor to determine the appropriate calibration coefficients
for the measurements obtained by that sensor.
Oximetry Operating Modes
The Passport’s three operating modes for SpO
2
enable it to make accurate measurements
despite differing levels of patient activity. In all three modes, the Passport updates its
measurements with every pulse beat. Data from the most recent beat replaces data from the
earliest beat and new averages are determined and displayed. The three modes are: 1
(default setting), 2, and 3.
1. The default operating mode, uses a 5 to 7 second averaging time and is useful in
situations in which the patient is relatively inactive.
