1.4 Mode of Displaying Oxygen Saturation
The Model 340V 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 340V 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 340V 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 340V 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
340V 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 %SpO
2
and 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.
