Does the MediWatch noninvasive blood pressure monitor accurately measure blood pressure compared to intra-arterial pressure in post-open heart surgery patients?
The MediWatch prototype demonstrated potential for accurate noninvasive beat-to-beat blood pressure monitoring when calibrated against intra-arterial pressure in stationary post-surgical patients.
Ng et al. (2004) studied Post-open heart surgery. MediWatch prototype vs. Intra-arterial pressure was evaluated on Accuracy of blood pressure measurements. The MediWatch prototype accurately tracked changes in systolic and diastolic pressures compared to intra-arterial pressure in post-open heart surgery patients under stationary conditions.
