Chapter 1:
Principles of Operation
Intended Uses
The Mediaid Model 100 pulse
oximeter is intended to non-
invasively measure arterial oxygen
saturation and pulse rate in
hospitals, physicians’ offices,
emergency medical facilities, or at
home. The Model 100 is not intended for continuous patient monitoring.
Principles of Pulse Oximetry
The Mediaid Model 100 pulse oximeter is designed to measure the
percentage of functional oxygenated hemoglobin to total hemoglobin.
Non-invasive arterial oxygen saturation measurement is obtained by
directing red and infrared light through a pulsating vascular bed. The
pulsating arterioles in the path of the light beam cause a change in the
amount of light detected by a photodiode. The pulse oximeter determines
the oxygen saturation of arterial blood by measuring the ratio of
transmitted red to infrared light within the pulse waveform. The non-
pulsatile signal is removed electronically for the purpose of calculation.
Therefore, skin, bone, and other non-pulsating substances do not
interfere with the measurement
of arterial oxygen saturation.
Intrinsic Calibration
The light absorption by hemoglobin is wavelength-dependent. Mediaid
red and infrared LED wavelengths are tightly controlled by testing in
production. In addition, the LED intensity recorded at the detector is
automatically adjusted for amplitude; this allows Mediaid pulse oximetry
sensors to be used interchangeably without calibration.
WARNING
Before using the Model 100,
become thoroughly familiar
with the information in this
manual.

Principles of Operation
- 2 -
Principle Features
The Mediaid Model 100 pulse
oximeter is a portable, lightweight,
pocket-sized instrument that
monitors functional arterial oxygen
saturation and pulse rate non-invasively.
The principal features of the Model 100 are as follows:
• Gives an alternating readout of SpO2percentage (%SpO2) and pulse
rate in beats per minute (BPM) on a 3-digit, 7-segment LED (light-
emitting diode) display.
• Can be used with either the Integral Finger Sensor or any Mediaid
pulse oximetry sensor that has a CompuShield®Connector that
attaches to the Cable Adapter.
• Increases the longevity and functionality of the pulse oximeter with the
removable and replaceable sensor modules.
• Performs approximately 1200 spot checks on a single 1.5 volt, AA-
sized alkaline battery (when using a Duracell®Ultra battery, which is
recommended).

pulse oximeter. If a battery leaks inside the instrument, return the
pulse oximeter for servicing.
• Remove the battery during shipment or if the Model 100 is to be idle
for several weeks.
Preventing Device Complications and Faulty Readings
To prevent device complications or faulty readings:
• Trim the patient’s long fingernails and remove artificial nails and thick
nail polish.
• Insert the patient’s finger completely into the Integral Finger Sensor.
• When using the Integral Finger Sensor, both the pulse oximeter and
the patient’s hand should rest on the same flat surface.
• Fit the sensor comfortably without constricting or compressing the
application site when using a sensor that is attached to the Cable
Adapter.
• Do not apply the sensor to anything but a well-perfused extremity.
• Do not apply the sensor on extremities that have blood pressure cuffs
or arterial or venous catheters.

Principles of Operation
- 4 -
• Avoid extremity positions that could compromise venous return.
• Keep sensors at heart level whenever possible.
• Check for intravascular dyes, which may affect pulse oximeter
readings.
• Turn off very bright lights, such as surgical, bilirubin, fluorescent, or
infrared heating if they interfere with sensor functioning. In cases
where such lights are unavoidable, cover the sensor site with an
opaque material.
• Route sensor cords carefully.
• Avoid applying excessive tension to the sensor or sensor cable.
• Consider conditions affecting the hemoglobin dissociation curve when
interpreting pulse oximeter readings (such as intravascular dyes).
• Keep patient movement to a minimum.
• When not in use, do not wind the sensor cord around the oximeter.
