Key result
Acute exposure to high altitude (4300 m) in healthy men resulted in a sustained decrease in forearm venous compliance averaging 17.0 ± 6.2%.

May explain ascent-related rises in central blood volume; extends venous physiology data but leaves open relevance to patients.

Does acute exposure to high altitude alter forearm venous compliance in healthy men?
Effect estimate: 17.0 ± 6.2% decrease
Acute exposure to high altitude decreases systemic venous compliance, which may play an important role in the increased central blood volume and cardiac output seen following ascent.
Weil et al. (1971) conducted an observational in Healthy. High altitude exposure (4300 m) was evaluated on Forearm venous compliance (17.0 ± 6.2% decrease). Acute exposure to high altitude (4300 m) in healthy men resulted in a sustained decrease in forearm venous compliance averaging 17.0 ± 6.2%.
