Evaluation of forearm vascular resistance during orthostatic stress: Velocity is proportional to flow and size doesn't matter.

Autor: V E Claydon, J P Moore, E R Greene, O Appenzeller, R Hainsworth

Publikováno v: PLoS ONE, Vol 14, Iss 11, p e0224872 (2019)

BackgroundThe upright posture imposes a significant challenge to blood pressure regulation that is compensated through baroreflex-mediated increases in heart rate and vascular resistance. Orthostatic cardiac responses are easily inferred from heart r

The Effect of Vasodilators on Pulmonary Hemodynamics in High Altitude Pulmonary Edema: A Comparison

Autor: G. S. Hartig, Benjamin D. Levine, E. R. Greene, Robert C. Roach, Peter H. Hackett

Publikováno v: International Journal of Sports Medicine. 13:S68-S71

High altitude pulmonary edema is characterized hemodynamically by a markedly restricted pulmonary vascular bed. Pulmonary vascular resistance is six to eight times higher than control values at altitude, and mean pulmonary pressure is generally eleva

Cardiac output measurements in congenital heart disease: validation of a simple, portable Doppler method

Autor: A L Caulder, J M Neutze, T L Gentles, E R Greene

Publikováno v: Journal of ultrasound in medicine : official journal of the American Institute of Ultrasound in Medicine. 20(4)

Noninvasive Doppler cardiac output measurements are clinical standards in adults and children. Presently, these standard Doppler methods generally require relatively expensive and large imaging equipment with complex signal-processing techniques. Thu

Arterial oxygen saturation for prediction of acute mountain sickness

Autor: R C, Roach, E R, Greene, R B, Schoene, P H, Hackett

Publikováno v: Aviation, space, and environmental medicine. 69(12)

Acute mountain sickness (AMS) is a usually self-limiting syndrome encompassing headache, nausea and dizziness. AMS is seen in those that go from low to high altitudes too quickly, without allowing sufficient time to acclimatize. At present, susceptib

Central vascular flow patterns in the alligator Alligator mississipiensis

Autor: G. M. Malvin, E. R. Greene, James W. Hicks

Publikováno v: The American journal of physiology. 269(5 Pt 2)

Many different flow patterns have been described through the central circulation of crocodilian reptiles. We tested the hypothesis that the vagus nerve stimulation promotes right-to-left (R-L) shunting in the alligator. Flow patterns were investigate

Effects of prolonged head-down bed rest on physiological responses to moderate hypoxia

Autor: J A, Loeppky, R C, Roach, M A, Selland, P, Scotto, E R, Greene

Publikováno v: Aviation, space, and environmental medicine. 64(4)

To determine the effects of hypoxia on physiological responses to simulated zero-gravity, cardiopulmonary and fluid balance measurements were made in 6 subjects (acclimatized to 5,400 ft) before and during 5 degrees head-down bed rest (HDBR) over 8 d
