The exceptional performance, ease of use and the superior quality of data obtained with Data Sciences' pressure implants have pushed pressure telemetry to the foreground in the cardiovascular sciences literature. Here are some reasons for this development:
cover species ranging in size from mice to non-human primates, dogs and miniature swine. The PA-C40 model for small animals (rats, guinea pigs, marmosets) is usually implanted intraperinoneally,
with the tip of the catheter (0.7 mm O.D.) inserted into the descending aorta. The larger PA-D70 model is typically placed under the skin at the flank of larger animals, with the tip of the
catheter inserted into (a branch of) the femoral artery. The latest addition to the range of pressure transmitters
was introduced in the fall of 1998: the PA-C20 for implantation in mice and other very small animals.

Battery life of either model guarantees continuous monitoring for six months; this period can be extended by using the magnetically activated on-off switch incorporated in the transmitter.
When using the DataQuest® system from DSI for computerized data acquisition, HR, and activity can easily be monitored in addition to systolic, mean and diastolic pressure. In addition, the Dataquest software is also extract respiration rate from the BP signal in rats.
Monitoring can also be done with any third party D/A hard- and software, or with a conventional chart recorder, by using special adapters.
If you wish to record BP and ECG in rats, be sure to look up the popular C50-PXT MultiplusTM transmitter.
