Occlusive cuff based automated tracking of continuous blood pressure using vessel buckling

Vessel buckling is integrated into oscillometry to determine the continuous mean arterial pressure. A microprocessor based feedback control is utilized to maintain the arterial pressure at the buckling point. The derivative of arterial volume is employed to indicate when the vessel is buckling. Implementation of an automated control loop improves the time it takes to track mean arterial pressure and allows the determination of frequency response parameters. Therefore, tracking of mean arterial pressure (MAP) will allow for the instantaneous determination of arterial pressure by later introducing a second simultaneous control loop.
