Measurement of blood pressure in unrestrained rats.
A method that allows continuous recroding of blood pressure in rats and other small animals is described. Surgical, recording, calibration, and catheter construction techniques are explained. The techniques allow blood pressure recording from free-roving rats for relatively long periods of time but do not require complicated maintenance procedures to insure catheter patency.
