Brief Summary

CASPER will examine the sleep patterns of ISS crewmembers by monitoring heart rates and information provided in a questionnaire. This information will help determine what might be causing any sleep disturbances and develop countermeasures.

    Experiment/Payload Description

    Research Summary

    • Sleep is important to the overall health of the ISS crewmembers.


    • CASPER will monitor the heart rates of the ISS crewmembers while they sleep in order to determine if there is any physiological reason for sleep disturbances. To supplement this data, the crewmembers will complete questionnaires before and after their sleep period.


    • The data that is collected from this investigation may help develop countermeasures for future long duration missions and patients on Earth who suffer from sleep disturbances.

    Description

    The objective of the CASPER (Cardiac Adapted Sleep Parameter Electrocardiogram Recorder) experiment is to test and evaluate a method of monitoring sleep disturbance and sleep stability in weightlessness. CASPER combines objective physiological data and subjective inputs. Physiological data is obtained through a specially adapted vest, worn by the astronaut, with embedded sensors and cabling that connects ECG (Electrocardiogram) electrodes, for measuring heart rate, to a PDA for storing the heart rate data. Subjective inputs are obtained via a questionnaire, which runs on the same PDA. A questionnaire is completed both prior to and after each sleep period that the heart rate is measured.

    Data collected on this mission can help to establish and distinguish the reasons and patterns of astronaut sleep disruption and facilitate the development of relevant countermeasures to monitor and ensure astronaut sleep stability during long term space flight.
