Roach R, Houston C, Honigman B, Nicholas R, Yaron M, Grissom C, et al.
West J Med . 1995 Jan; 162(1):32-6. PMID: 7863654
We studied the physiologic and clinical responses to moderate altitude in 97 older men and women (aged 59 to 83 years) over 5 days in Vail, Colorado, at an elevation...

Loeppky J, Fletcher E, Roach R, LUFT U
Respir Physiol . 1993 Oct; 94(1):109-20. PMID: 8272578
Empirical relationships are demonstrated for whole blood base excess (BE) and CO2 content (CCO2), both calculated from in vivo measurements of PCO2, pH, hemoglobin concentration and O2 saturation. Comparisons are...

Loeppky J, Roach R, Selland M, Scotto P, Greene E, LUFT U
Aviat Space Environ Med . 1993 Apr; 64(4):275-86. PMID: 8476367
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...

Loeppky J, Roach R, Selland M, Scotto P, Luft F, LUFT U
Aviat Space Environ Med . 1993 Apr; 64(4):265-74. PMID: 8476366
To determine the effects of hypoxia on fluid balance responses to simulated zero-gravity, measurements were made in six subjects (acclimatized to 5,400 ft; 1,646 m) before and during -5 degrees...

Hackett P, Roach R, Hartig G, Greene E, Levine B
Int J Sports Med . 1992 Oct; 13 Suppl 1:S68-71. PMID: 1483798
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...

Loeppky J, Scotto P, Riedel C, Roach R, Chick T
J Appl Physiol (1985) . 1992 May; 72(5):1787-97. PMID: 1601787
To investigate the relationship between hypoxic pulmonary vasoconstriction and respiratory and metabolic acidosis and respiratory alkalosis, the pulmonary gas exchange and pulmonary hemodynamic responses were measured in anesthetized, paralyzed, and...

Grissom C, Roach R, Sarnquist F, Hackett P
Ann Intern Med . 1992 Mar; 116(6):461-5. PMID: 1739236
Objective: To determine the efficacy of acetazolamide in the treatment of patients with acute mountain sickness and the effect of the drug on pulmonary gas exchange in acute mountain sickness....

Swenson E, Leatham K, Roach R, Schoene R, MILLS Jr W, Hackett P
Respir Physiol . 1991 Dec; 86(3):333-43. PMID: 1788493
The efficacy of carbonic anhydrase (CA) inhibitors in amelioration of periodic breathing during sleep at high altitude is not fully understood. Although CA is present in a number of tissues,...

Med Sci Sports Exerc . 1990 Dec; 22(6):804-10. PMID: 2287258
To assess the ventilatory adaptation during gradual ascent to extreme altitude, we studied seven healthy males as part of the 40 d simulated ascent of Mt. Everest in a hypobaric...
