Background Space is the ultimate health monitoring frontier given the lack of access to specialized equipment and personnel. Primary health monitoring of vital signs remotely using a small payload size might be optimal and potentially cost-effective.

Objective

To perform a pilot, feasibility study using a miniaturized Oxehealth camera monitoring simulated vital signs during a suborbital flight on EXOS aerospace inaugural SARGE rocket.

Design/Methods The Center for Applied Space Technology (C-AST) coordinated a payload integration team with EXOS aerospace for the inaugural suborbital flight using the SARGE (Suborbital Autonomous Rocket with Guidance), Mayo Clinic physician scientists, and Oxehealth camera technology. A standard National Aeronautical Space Administration (NASA) BRIC-100 system was utilized for feasibility study. Oxehealth camera is a machine learning, software based PPG (photoplethysmography) system that detects pulse rate from pixel shifts in skin color, and also detect body motion for respiratory rate non-invasively using digital cameras. The team configured a Hero GoPro high-definition camera that was affixed to a distant target (analogue watch) with moving second hand as the simulated pulse Rate/respiratory rate targets. A supplemental battery supply, as well as a digital datalogger 3-D accelerometer was additionally incorporated into the system for recording with live video recording during the launch.

Results The EXOS SARGE rocket successfully launched achieved an initial suborbital altitude of 28KM before achieving apogee. On flight recording showed immediate reach of apogee followed by 1min and 10sec of microgravity during descent. On board camera visualization of analogue clock target showed success in tracking during ascent, apogee, and descent. This data suggest that onboard rocket launch video PPG via the Oxehealth camera should be feasible for human flights to space.

Conclusions

Onboard non-invasive, camera-based vital sign monitoring during a suborbital rocket launch, apogee, and descent appears feasible within a small NASA BRIC-100 confined space. Future space health monitoring simulation studies are needed.
