Chapter 1:
Principles of Operation of
the Model 5340V
1.1 Intended Uses
The Model 5340V is intended to
continuously monitor an animal’s
arterial oxygen saturation and
heart rate. It also provides body
temperature information every two
minutes or on command.
1.2 Principles of Pulse Oximetry
The Mediaid Model 5340V Pulse Oximeter is designed to measure the
percentage oxygen saturation (%SpO2) of functional 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 measures within the
pulse waveform the ratio of transmitted red to infrared light, and thereby
determines the oxygen saturation of arterial blood. 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
calculation of arterial oxygen saturation.
1.3 Principle of Measuring Body Temperature
The Mediaid Model 5340V’s temperature component is designed to
measure the animal’s core temperature with a rectal thermistor sensor.
The thermistor’s highly sensitive resistance decreases with increasing
temperature. The LED display indicates the animal’s body temperature.
WARNING
Before using the Model 5340V, the
user should become thoroughly
familiar with the information in this
manual and with all information
included with the sensors.

Principles of Operation of the Model 5340V
- 2 -
1.4 Mode of Displaying Oxygen Saturation
The Model 5340V displays pulse oximetry data as follows:
• A normal steady display signifies that the pulse oximeter has received
at least three intelligible pulses in the last 30 seconds. The display is
updated each time a normal pulse is received.
• A blinking display indicates that the Model 5340V has received no
usable pulses for at least 30 seconds. The displayed pulse oximetry
readings are at least 30 seconds old
• A blinking display with a 1-second warning tone every 10 seconds
indicates that the Model 5340V has received no usable pulses for at
least 60 seconds. The displayed pulse oximetry readings are at least
60 seconds old.
1.5 Principal Features
The Mediaid Model 5340V Pulse Oximeter is a portable, lightweight
instrument designed to non-invasively monitor arterial oxygen saturation,
heart rate and body temperature. The principal features of the Model
5340V are as follows:
• Displays with two bright Light Emitting Diodes (LEDS). Indicates
oxygen saturation, heart rate, and temperature.
• Provides a constant readout of oxygen saturation in %SpO2and heart
rate in beats per minute (BPM).
• Issues an audible tone that sounds for each pulse and varies in pitch
with oxygen saturation - falling in pitch with reduced saturation and
rising in pitch as saturation increases.
• Sounds a double tone to indicate each time the animal’s body
temperature is measured.
• Provides visual and audible alarms for oxygen saturation and pulse
rate monitoring.
• Allows for data transmission through the DATA PORT.
• Performs a functional test at power-on. Additional diagnostics tests
can be initiated manually.
• Alerts to a low-battery condition with a front-panel LED indicator.
• Powered by either standard electric power or an internal, recharge-
able Nickel-Cadmium (NiCad) battery.
• Compatible with all Mediaid veterinary sensors with RJ12 connectors.

A. Power On/Off Key
The unit is powered on with one short depression (less than
one second) of the Power On/Off Key. A 1-second display
and indicator test is performed automatically, and all Light
Emitting Diodes (LEDs) are illuminated. Carefully observe the
LED displays for proper operation of all segments. A nonfunctioning
segment will result in an incomplete numeral and possible erroneous
reading.
One long depression (3 seconds or longer) of the Power On/Off Key
initiates the Internal Confidence and Diagnostic Tests (see section
“Tests” in Chapter 3).
B. Oxygen Saturation Display
Whenever the pulse oximeter receives at least three (3) pulses during a
30-second period, the left LED displays the animal’s oxygen saturation
levels. The display is updated with every normal pulse. A blinking display
signals that %SpO2monitoring may be adversely affected, and indicates
the continuous presence (30 seconds or more) of significant patient
movement or light-source interference.
C. Pulse Rate Display
Whenever the pulse oximeter receives at least three (3) pulses during a
30-second period, the right, three-digit LED displays the patient’s heart
rate in beats-per-minute (BPM).
WARNING
A non-functioning LED segment may yield inaccurate readings.
WARNING
A blinking display indicates that the Model 5340V has received
NO usable pulses for at least 30 seconds. The displayed pulse
oximetry readings are at least 30 seconds old.
