Intra-arterial Pressure Measurement with Strain Gauge and Amplifier *

Abstract

The purpose of this paper is briefly to describe intra-arterial pressure recording by means of a strain gauge pressure transducert and amplifiers. The use of resistance wire strain gauges for blood pressure recording with galvanometers has already been described.1"8 The use of the strain gauge with electronic amplification as a plethysmograph has also been… (More)
