Equivalence between Invasive and Oscillometric Blood Pressure Measurements during Controlled Haemorrhage in Anesthestised Horses

This is the raw blood pressure data from an experiment where invasive blood pressure was compared to oscillometric blood pressure in horses. Under isoflurane anaesthesia, blood was removed every 10 minutes at 5 ml/kg bwt increments up to 25 ml/kg bwt and returned in a similar fashion. Paired NIBP (from the tail base with a cuff width-to-tail circumference ratio of 0.25) and invasive MAP measurements (metatarsal, facial, and transverse facial arteries; MT, FA, TFA) were obtained before and during blood removal/return. Eleven horses were studied.
