ISS Science for Everyone

Science Objectives for Everyone
The Studying the Body’s Physiological Functions Using a Non-contact Method During Sleep During Long-term Space Flight (Sonokard) studies the sleep-wake cycle in humans spending a prolonged period in space. Sonocard develops proposals to improve the system for medical monitoring of crew members, based on the use of a non-contact method of recording physiological data during sleep. During the Sonocard, microscopic oscillations associated with heart rate, respiration, and motor activity are recorded. The study focuses on cardiorespiratory homeostasis and mechanisms for regulating the cardiorespiratory system.
Science Results for Everyone
Quiet: astronauts sleeping. This investigation evaluated collection of cardiorespiratory data from crewmembers while they sleep, using a device in the breast pocket of a special shirt. This no-contact method allows continuous monitoring without interfering with sleep, and the results confirm that it is practical. Researchers obtained data on pulse and respiratory rate during sleep that is important for evaluating and predicting adaption to long-duration space flight and for monitoring crew health. Nighttime data collected following extra-vehicular activity (EVA), for example, showed that each subsequent EVA increases stress on the autonomous regulation of heart rate and respiration.

Applications

Space Applications
Implementation of the experiment has opened the door to creating a fundamentally new type of medical monitoring system, one that allows the acquisition of information necessary for assessing the functional status of the crew during nighttime, with a minimal amount of work time required for performing medical experiments. In addition, this system could become an important element for assuring safety of manned flights, since it allows for the transition from periodic to constant monitoring.

Earth Applications
The results obtained are useful in various fields of medicine: clinical and preventive medicine, environmental medicine, and medicine for extreme environments.

Results/More Information

The main scientific result of the Sonocard experiment was confirmation of the capability to evaluate sleep quality and the effectiveness of restoring functional reserves without the use of cumbersome polysomnography equipment and the reality of using this new approach to perform practical tasks of medical monitoring. Fundamental scientific results included obtaining systematic data on pulse and respiratory rate during sleep in long-term microgravity and obtaining systematic data on the status of various elements of the involuntary regulation system during sleep in long-term weightlessness. Sonocard was also used in determining the unique aspects of reconstructing autonomous regulation at various stages of flight in relatively stable sleep conditions without the effects of stressor factors of the work regimen in flight and discovery of facts concerning the reduction of functional reserves in crew members’ bodies during the acute period of weightlessness adaptation. Finally, it was utilized in obtaining the first nighttime recordings after the performance of an extravehicular activity (EVA); it was shown that each subsequent EVA was characterized by higher stress on the regulatory mechanisms. This required appropriate mobilization of the body’s functional reserves. Overall, the results of the experiments performed showed the possibility of obtaining real-time information on cosmonauts' functional status and on processes for restoring functional reserves at various phases of flight.
