Regulation and Biomechanics of Respiration in Space Flight (Dykhanie) - 02.25.15
Dykhanie (Breathing) investigation studies the fundamental physiological mechanisms of external breathing function under long-duration space flight conditions. Science Results for Everyone
Don’t forget to breathe! This investigation looked at the mechanics of breathing in space. Data analysis showed no statistically significant changes in the volume or rate at which crew members breathe. However, the method by which breathing at rest is voluntarily controlled was affected by the transition from Earth to spaceflight and vice versa. The changes include increase in duration between breaths, decrease in variability of breathing pattern, and shifts in the voluntary control of respiratory movements. These are likely caused by changes in the body’s breathing regulation system and require further study. Experiment Details
