Setting a VO2 Max Standard for NASA Astronauts During Spaceflight

Aerobic fitness is best measured by Maximal Aerobic Capacity or VO2 Max which is defined as a measure of oxygen utilization and transport. Increased Vo2 max indicates improved oxygen consumption during high level exercise and is widely accepted as a predictor of an individual's likelihood of successfully completing a demanding task. As such, agencies and organizations have adopted VO2 max as part of a comprehensive set of physical requirements. The purpose of this study is to review the literature and existing medical and occupational VO2 max data, to propose a VO2 max standard for NASA astronauts for training and spaceflight.

NASA Musculoskeletal Space Medicine and Reconditioning Program

The Astronaut Strength, Conditioning, and Rehabilitation (ASCR) group is comprised of certified strength and conditioning coaches and licensed and certified athletic trainers. The ASCR group works within NASA s Space Medicine Division providing direction and supervision to the astronaut corp with regards to physical readiness throughout all phases of space flight. The ASCR group is overseen by flight surgeons with specialized training in sports medicine or physical medicine and rehabilitation. The goals of the ASCR group include 1) designing and administering strength and conditioning programs that maximize the potential for physical performance while minimizing the rate of injury, 2) providing appropriate injury management and rehabilitation services, 3) collaborating with medical, research, engineering, and mission operations groups to develop and implement safe and effective in-flight exercise countermeasures, and 4) providing a structured, individualized post-flight reconditioning program for long duration crew members. This Panel will present the current approach to the management of musculoskeletal injuries commonly seen within the astronaut corp and will present an overview of the pre-flight physical training, in-flight exercise countermeasures, and post-flight reconditioning program for ISS astronauts.

Concept of Operations Evaluation for Mitigating Space Flight-Relevant Medical Issues in a Planetary Habitat

Introduction: Analogue environments assist the NASA Human Research Program (HRP) in developing capabilities to mitigate high risk issues to crew health and performance for space exploration. The Habitat Demonstration Unit (HDU) is an analogue habitat used to assess space-related products for planetary missions. The Exploration Medical Capability (ExMC) element at the NASA Johnson Space Center (JSC) was tasked with developing planetary-relevant medical scenarios to evaluate the concept of operations for mitigating medical issues in such an environment. Methods: Two medical scenarios were conducted within the simulated planetary habitat with the crew executing two space flight-relevant procedures: Eye Examination with a corneal injury and Skin Laceration. Remote guidance for the crew was provided by a flight surgeon (FS) stationed at a console outside of the habitat. Audio and video data were collected to capture the communication between the crew and the FS, as well as the movements of the crew executing the procedures. Questionnaire data regarding procedure content and remote guidance performance also were collected from the crew immediately after the sessions. Results: Preliminary review of the audio, video, and questionnaire data from the two scenarios conducted within the HDU indicate that remote guidance techniques from an FS on console can help crew members within a planetary habitat mitigate planetary-relevant medical issues. The content and format of the procedures were considered concise and intuitive, respectively. Discussion: Overall, the preliminary data from the evaluation suggest that use of remote guidance techniques by a FS can help HDU crew execute space exploration-relevant medical procedures within a habitat relevant to planetary missions, however further evaluations will be needed to implement this strategy into the complete concept of operations for conducting general space medicine within similar environments

Cases in Space Medicine: Right Lower Quadrant Abdominal Pain in a Female Crewmember on the International Space Station

A case study of a medical emergency aboard the International Space Station is reviewed. The case involves a female crewmember who is experiencing acute abdominal pain. The interplay of the Crew Medical Officer (CMO) and the NASA Flight Surgeon is given. Possible diagnoses, and advised medical actions are reviewed. Along the case study questions are posed to the reader, and at the end answers are given.
