Metabolic Diagnostic in Space by Full Wearable Respiratory Analysis (MetabolicSpace)

Pulmonary physiology
Species Studied
Scientific Name: Homo sapiens Species: Human

Cardio-pulmonary evaluations during exercise onboard the International Space Station (ISS) have typically been done using the Pulmonary Function System (PFS). The PFS is a stationary system that may require the subject to breathe special gas mixtures and exercise at fixed locations.

This experiment is a technology demonstration of a system (MetaSpace) designed to allow cardio-pulmonary evaluations to be performed in space while the subject engages in physical activity with unrestricted mobility.

While wearing a commercial device that has been customized and space qualified, it is expected that the astronaut subject will be able to move freely without the encumbrances of cables, gas lines, and electronic boxes and no special gas mixtures will be required. Parameters measured by the system are expected to be sufficient to accomplish a complete evaluation of exercise performance and metabolism.

The primary objectives of this investigation are to:

  1. Validate the functionality of the wearable system when used by astronaut subjects in microgravity
  2. Gain experience leading to enhancement of the wearable system for future space applications
