Detect the blood pressure signal and derive systolic, diastolic changes.
NIBP, or non-invasive blood pressure, can be recorded from both animals and humans. The methods used to measure NIBP in human and animal subjects differ.
Human subjects
In humans, automated NIBP systems can sample changes in relative blood pressure over time, simulating a real-time blood pressure measurement. Non-invasive blood pressure derived from a human subject is typically sampled using an approximation derived from a waveform sampled at the finger. Various algorithms and reconstructions are applied to derive an approximation of arterial blood pressure. These signals are typically used as an indicator of autonomic function, blood pressure changes in exercise, and cardiovascular health.
Rodent subjects
In rodents, NIBP measurement is performed using an occlusion method. A cuff is inflated around the major artery running through the tail. As this pressure is released, and measured, a pulse transducer indicates the return of blood flow to the artery. Systolic pressure can be estimated by finding the pressure at which this pulse returns to the tail.
LabChart software is designed specifically for life science data and provides up to 32 channels for data display and analysis options that are powerful and easy to use. With auto-recognition of ADI and LabChart Compatible hardware, multi-window views, one touch recording, simultaneous recording from multiple devices, specialized preconfigured settings, easy sharing options and an interface that can be customized to show only the features you want to use.
Rodents undergoing an NIBP measurement must first acclimate to the procedure. A reasonable amount of time training your animals in a restrainer, with the measurement device applied, will lower the chance that a fear reflex will stop blood flow to the tail.
