| DSI PhysioTel® PA-C40 for Small Animals |
The PhysioTel® PA series transmitter model PA-C40 measures pressure and activity in small animals. Other models in the PhysioTel® PA series transmitter series include PA-C10 for mice and PA-D70 for large animals. This model is capable of measuring arterial, ocular, uterine, penile, bladder, pleural and left ventricular pressure. Other parameters such as heart rate, systolic, diastolic and mean pressure can be derived from these waveforms. Similar to all models in the PA transmitter series, the PA-C40 is completely implantable, eliminating the need for flushing and other catheter maintenance issues. |

Specifications are nominal. Some parameters, such as minimum animal weight, may vary depending on research methodology and preference. For example, some researchers have implanted the DSI PhysioTel® PA-C40 transmitter in rats smaller than 175 grams. Minimum animal weight may vary based upon placement location, surgical skill and strain of animal used. Larger cage sizes also can be accommodated with special configurations. Specifications, performance and accuracy are valid for the warranted battery life and only when data are recorded using Dataquest A.R.T. with factory-supplied calibration values. Transmitters may work over wider ranges with reduced accuracy.
When measuring pressure in mice, small animals, and large animals using DSI transmitters, it may be necessary to use an Ambient Pressure Reference Monitor to ensure accurate pressure measurements.
