Physical workload: OxyCon (metabolic rate), Equivital (temperature, acceleration, heart rate)
Cognitive workload: fNIRS, EEG, eye-tracking
EVA Physiology
Potential for wearables for Doppler ultrasound measurement to monitor for nitrogen bubbles / decompression sickness
Background: Standard atmosphere is 14.7 psi (78% nitrogen, 21% oxygen, argon, and CO2)
Spacesuits use 100% oxygen at 4.3 psi
Exploration atmosphere, currently validating in chamber studies: 34% Oxygen, 66% Nitrogen, 8.2 psi
Pre-breathe with pure oxygen to remove nitrogen from bodily fluids and tissues
To prevent gas bubbles when pressure is reduced, aka "the bends“
