Standalone Pulse Oximeter

CANL-425SV-A
Standalone Pulse Oximeter

Many scientists have realized an increased demand for non-invasive methods of obtaining cardiovascular measurements in laboratory animals, such as rats and mice. With this need in mind, Med Associates has developed a veterinary quality pulse oximeter that allows researchers to obtain measurements of percent arterial oxygen saturation (SpO2) and heart rate in anesthetized animals using a non-invasive transducer applied to the surface of well-perfused tissue such as the base of the tail, ear, tongue, or paw.

This standalone pulse oximeter (CANL-425SV-A) features a front-panel display that gives continuous read outs of heart rate and SpO2. LED lights indicate a sensor alarm, signal out of track, bad pulse signal, and sensor disconnect.

The pulse oximeter signal can be connected to the standard USB port on a computer. Software is included which provides a chart recorder-like display of the arterial pulse tracing as well as read outs for heart rate and SpO2. Data can also be stored as ASCII text files for importing into graphing or statistics programs.

For the ultimate in data acquisition, the pulse oximeter is available with analog outputs (BNC-type connector) that can be used to acquire the pulse rate, raw plethysmograph, and SpO2 using an analog-to-digital data acquisition system which may already be in place in a lab.

For labs that frequently perform surgeries, this pulse oximeter is the ideal tool for monitoring anesthesia
levels during surgery. Applications include monitoring arterial oxygen saturation during respiratory physiology studies on hypoxia.

Accessories

For the most accurate pulse oximeter signals in rodents or larger animals, it is important that the animal is motionless and the sensor is securely held in place. It may take several tries to determine the ideal sensor positioning for the application—well-vascularized muscles that have a substantial tissue mass, such as the thigh or upper part of the forelimbs, work the best.
	TDR-43C Clip Sensor for Rodents or Larger Animals For the most accurate signals in rat and mouse, use this clip sensor positioned on the upper thigh muscle. For larger animals, such as dogs, place sensor on paw, tongue, or other thin tissue. The fur from the recording site should be removed first using a depilatory cream.
	TDR-43W Wrap Sensor for Rat or Mouse Use this wrap sensor for rat or mouse on the tail. The fur from the recording site should be removed first using a depilatory cream.
	TDR-43T Transflectance Sensor for Larger Animals Use this transflectance sensor on the ear lobe, tail, paw or other well-vascularized region. The fur from the recording site should be removed first using a depilatory cream.
	TD-43 Disposable Sensor This disposable sensor may be reused several times and is held in place by adhesive tape. The fur from the recording site should be removed first using a depilatory cream. < back to top>

Pulse Oximeter Software

The standalone pulse oximeter can be connected to a USB port on a computer. Software that provides a visual chart recorder-like display of the arterial pulse tracing, heart rate, and SpO2, is included. Sensor indicators and audible alarms can be configured to alert the researcher that the sensor is disconnected, an artifact occurred, or that heart rate or SpO2 are out of a specified range (too high or too low). Data can be stored as ASCII text files for importing into graphing or statistics programs. For users who want to record pulse oximetry data along with other signals, such as temperature, electrophysiological recordings, or other parameters using their own data acquisition system, the pulse oximeter provides analog outputs for the plethysmogram (arterial pulse waveform), heart rate, and SpO2. For labs that frequently perform surgeries, this pulse oximeter is the ideal tool for monitoring anesthesia levels during surgery. Applications include respiratory physiology, hypoxia, and surgical anesthesia monitoring.
