Implication

Novel non-cannulating BP transducer remains exploratory; leaves open calibration and validation for clinical use.

Key Points

The research aimed to create a transducer capable of continuously measuring arterial blood pressure without the need for cannulation.
Developed two measurement techniques: indirect and direct;
Analyzed and tested experimental prototypes based on a mathematical model of the transducer system;
Performed tests on large superficial arteries for validation against standard methods.
Experimental transducers provided measurements consistent with model predictions;
Results compared favorably to sphygmomanometer determinations;
Successful continuous measurement achieved without encumbering the subject.

Pressman et al. (1963) studied Arterial blood pressure. Transducer measuring restraining force of arterial deflection vs. Sphygmomanometer was evaluated on Blood pressure measurement. An experimental transducer measuring the restraining force of arterial deflection provided continuous external blood pressure measurements comparable to sphygmomanometer determinations.
