An Automated Tilting Bed for Continuous Control of Blood Pressure

An automative system for continuous maintainence of arterial pressure within set bounds by means of a bed programmed to tilt head up or down in response to fluctuations in arterial pressure has been designed. Pressure is measured continuously with an indwelling arterial pressure transducer. The system hastened return of blood pressure to normotensive levels in 15 dogs made hypertensive with metaraminol or hypotensive with trimethaphan camphorsulfonate.
