Does acute hypobaric hypoxia affect thermoregulatory and circulatory responses during cold air exposure?
Acute hypobaric hypoxia affects pulse rate but not overall thermoregulatory responses during cold air exposure.
These results suggest that hypobaric hypoxia during cold exposure did not alter the overall thermoregulatory responses. However, hypobaric hypoxia did affect pulse rate regardless of cold exposure.
Shin et al. (Thu,) studied this question.
