ISS Science for Everyone

Science Objectives for Everyone
The Study of the Regulation and Biomechanics of Respiration in Spaceflight (Dykhanie) investigates upper respiratory functions in long-term orbital flight on the International Space Station (ISS) in order to improve the medical monitoring and countermeasures system for future long-duration crew members.
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.

Applications

Space Applications
Investigating how weightlessness affects the respiratory system and regulation (including voluntary control) of this function in long-term spaceflight is important both for the study of space physiology and space medicine, since new findings serve as the basis for improving and developing special countermeasures for the deconditioning and rehabilitation of the respiratory muscles.

Earth Applications
Dykhaniye studies the condition of the respiratory system in weightlessness, but knowledge gained from the experiment can also benefit respiratory research on Earth.

Results/More Information

A large amount of scientific information was obtained during the experiment, and analysis showed that no statistically significant changes occurred in the volume/rate of breathing at rest or breathing reserve indicators in the group under spaceflight conditions. Analysis of spirometry (method in which breathing is voluntarily controlled after breathing at rest) parameters showed that in both the transition from Earth to spaceflight conditions and vice versa, voluntary control of respiratory movements was destabilized. Therefore, as a result of carrying out the Dykhaniye experiment on the ISS, no significant changes were found in external respiration volume/rate in the crew members tested. The increase in the duration of holding the breath, the decrease in variability of breathing pattern time parameters, and shifts in the voluntary control of respiratory movements were likely caused by changes in the system of breathing regulation, which requires further in-depth study.
