The Respiratory Support Pack (RSP) is crucial for space missions, but needs upgrades. This review assesses current mechanical ventilation strategies for astronauts facing lung issues.

Area of Science:

  • Space medicine
  • Respiratory physiology
  • Biomedical engineering

Background:

  • The International Space Station (ISS) requires advanced medical equipment.
  • Acute pulmonary dysfunction poses a significant risk to astronaut health.
  • The National Aeronautics and Space Administration (NASA) developed the Respiratory Support Pack (RSP).

Purpose of the Study:

  • To critically appraise the current RSP.
  • To evaluate mechanical ventilation strategies for spaceflight.
  • To recommend RSP enhancements for astronaut survival.

Main Methods:

  • Review of existing literature on mechanical ventilation.
  • Analysis of closed-loop ventilation strategies.
  • Assessment of the RSP's capabilities and limitations.

Main Results:

  • Current RSP has limitations in managing severe pulmonary impairment.
  • Closed-loop ventilation offers potential but requires adaptation for space.
  • Existing strategies may not fully address unique spaceflight challenges.

Conclusions:

  • The RSP requires significant upgrades to improve its efficacy.
  • Advanced closed-loop systems should be explored for future space missions.
  • Enhanced respiratory support is vital for astronaut safety and mission success.
