Fundamentals of Anesthesiology for Spaceflight [PDF]

Journal of Cardiothoracic and Vascular Anesthesia, 2016
SPACE EXPLORATION BEYOND low Earth orbit has been termed as “exploration class space missions.” Such future missions may involve extended flights to the Moon, asteroids, or Mars and will most likely engage not only governmental space agencies but also the private sector, in what some have termed “the new space race.” During those missions, the risk for

Impacts of the Spaceflight to the Immune System

Hanggong uju uihakoeji, 2021
Changes the gravity has a significant affect on the immune system. Astronauts experience the gravity changing during spaceflight, especially when launching and landing they experience hypergravity, and during spaceflight they feel microgravity.

Text-to-image artificial intelligence to understand astronaut visual phenomena during spaceflight

The Pan-American Journal of Ophthalmology, 2023
Astronauts have documented visual phenomena during spaceflight. However, given that these are only experienced by the astronaut themselves, these unique neuro-ophthalmic visual phenomena occur while in space which remain poorly understood by ...

Treadmill exercise within lower body negative pressure protects leg lean tissue mass and extensor strength and endurance during bed rest. [PDF]

, 2016
Leg muscle mass and strength are decreased during reduced activity and non-weight-bearing conditions such as bed rest (BR) and spaceflight. Supine treadmill exercise within lower body negative pressure (LBNPEX) provides full-body weight loading during BR

Direct Gravity‐Induced Modulation of Cardiac Conduction Pathways Evidenced Through Propagation Features in Electrophysiological Mapping

Advanced Materials Technologies, EarlyView.
A high‐density wearable body‐surface potential mapping array reveals how gravity reshapes cardiac conduction in real time. By resolving spatiotemporal delay patterns invisible to conventional ECG, the platform uncovers posture‐dependent electrophysiological adaptations across the thorax.
