Sensors for oxygen in liquids have been commonly used for clinical chemistry applications. Optical approaches to blood gas applications have been known for some time2. The opportunity for fiber sensor applications in this area is created by familiar

Fifty-three healthy US Air Force aircrewmen, 26–55 yr old, volunteered for a centrifuge study designed to determine the effect of age on relaxed +GZ tolerance. Each was subjected to G forces of gradual and rapid onset, with G tolerance determined b

Heart rates, blood pressures, and functional responses to submaximal, maximal and postexertional treadmill testing are presented for a group of 704 healthy, asymptomatic aircrewmen referred to the USAF School of Aerospace Medicine. The indicated meas

This paper presents the operation of a digital computer program, VECTAN II, for the spatial analysis of the vectorcardiogram (VCG). The program incorporates a unique waveform recognition algorithm based on the spatial vector length which has been sho

Electrocardiographic (ECG) signals were recorded from ten normal resting male subjects using two bipolar lead configurations: sternal and axillary. The recordings were made under low-noise conditions with a recording system bandpass extending from dc

Forty asymptomatic male patients at low risk for cardiovascular disease completed maximal treadmill testing. Electrocardiograms from leads CC5, CM5, V5, Yh and Z were recorded across multiple pretest, exercise and recovery conditions. ECG waveforms w

The effect of extended duration tilt on hypertensives has not been studied before; the effect on normotensives has not been fully documented. Twenty-one borderline essential hypertensive patients and 23 normotensive patients were selected for tilt ta

The automated location of T-wave fiducial points in single lead exercise ECG's is facilitated by using R-Tmax and R-Tend intervals predicted from heart rate. Predictive equations for these intervals were developed; algorithms were subsequently design

Summary The effects of 70-degree weight-bearing tilt and of static standing were studied in aircrewmen who were assigned to two groups, depending on whether they were normotensive or had a history of borderline essential hypertension. Noninvasive met
