There are several ways to assess blood pressure in rodent models. Non-invasive tail cuff systems enable repeated measurements over the course of a longitudinal study, while acute measures may be obtained with highly accurate vascular and ventricular pressure catheters. For studies that require chronic pressure monitoring, telemetry implants offer long-term solutions.
Chronic blood pressure monitoring can be achieved with implantable telemeters. Kaha Sciences Telemetry systems enable continuous arterial, venous or ventricular pressure recordings in conscious, freely moving rats using high-fidelity, solid-state pressure catheters.
Non-Invasive Blood Pressure
For studies that require non-invasive, repeated blood pressure measurements, tail cuff blood pressure systems are an excellent option. The NIBP systems are an affordable, easy to use system that enables real-time acquisition and review of blood pressure waveforms in up to six animals simultaneously.
For acute studies, pressure catheters can rapidly detect changes in vascular or ventricular pressure with high precision. Coupling pressure catheters to a surgical monitor (RSM+) enables visualization of several cardiovascular parameters simultaneously to ensure accurate surgical procedures.
