Introduction
Introduction
The Model 2500A VET is a digital handheld pulse oximeter that displays numerical values for blood
oxygen saturation (%SpO
2
) and pulse rate on animals. It provides audible and visual alarms for both
medium and high priority conditions.
The pulse oximeter determines functional oxygen saturation of arterial hemoglobin (SpO
2
) by
measuring the absorption of red and infrared light passing through perfused tissue. Changes in
absorption caused by the pulsation of blood in the vascular bed are used to determine oxygen
saturation and pulse rate.
Oxygen saturation and pulse rate values are displayed by light-emitting diode (LED) digital displays.
On each detected pulse, the Pulse Quality indicator blinks. Pulse quality signals are graded as good
(green), marginal (amber), or inadequate (red) and are indicated as such by the Pulse Quality
indicator. This simple method gives the user a pulse-by-pulse visual indication of waveform signal
quality without requiring the user to perform complex waveform analysis.
The Model 2500A VET pulse oximeter may be used with a variety of Nonin-branded veterinary
oximeter sensors.
A sensor disconnect or malfunction is indicated by a red blinking Pulse Quality indicator and/or a
dash to the left of the SpO
2
value on the LED display. When adequate pulse signals are not received,
the SpO
2
and/or pulse rate numerical values are replaced by dashes.
The device requires no routine calibration or maintenance other than replacing batteries or
recharging the battery pack. This device typically operates for 60 hours continuously between
alkaline battery replacements, or for 40 hours with the Model 2500B Rechargeable NiMH (Nickel
Metal Hydride) Battery Pack.
