Clinical trials: Altitude
Hypobaric Hypoxia
Pharmacological Countermeasures for High Altitude
The aim of this randomized, double-blind study is to determine whether erythropoietin (Procrit) and acetazolamide: 1) mitigates altitude-induced decrements in performance at moderate altitude (3,000 m) and 2) mitigates…

Pre-Eclampsia
Are There Sleep-related Factors That Contribute to an Increased Incidence of Pre-eclampsia at Altitude?
Women at altitude have an increased incidence of pre-eclampsia. Populations at altitude have a greater incidence of sleep apnea. And women with sleep apnea are at increased risk of developing preeclampsia.
