The Sentinel Blood Pressure unit is a new concept in blood pressure monitoring. The unique idea is to have each type of monitoring method available in one unit so that the appropriate module can be used according to clinical requirements. For example a critical care patient may be monitored using a direct blood pressure module and that same patient may be subsequently monitored in kennels or during a consultation using the NIBP or Doppler module. Equally, having a Doppler module for monitoring avian, reptile or other exotic species where conventional pulse-monitoring techniques are difficult or unreliable means that the Sentinel unit will find use across the broad range of species encountered. The modular nature of Sentinel offers a cost-effective way of addressing your varied blood pressure monitoring needs at a reduced cost compared to buying separate units. An additional feature of Sentinel is that there is an option to have your results displayed and saved on a computer, via a USB or wireless link. Output from the Sentinel monitor is compatible with our VitalMonitor/VitalStore software suite and will simply appear as a new monitoring device on the computer software.
