Keys, Indicators and Symbols
- 6 -
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 %SpO

monitoring 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.
NOTE
If the unit is powered by battery and a pulse search is
unsuccessful for any reason, the Model 340V automatically
powers off after one minute of unsuccessful pulse search.
