Mechanical ventilation in orbit: emphasis on closed-loop ventilation.
As part of a Crew Health Care Maintenance System onboard the International Space Station, the National Aeronautics and Space Administration has included a Respiratory Support Pack (RSP) to resuscitate or sustain a crew member with an acute impairment in pulmonary function. This article provides a critical appraisal of the RSP and of current strategies for mechanical ventilation in space. Various closed-loop ventilation strategies are reviewed,and their appropriateness for respiratory support in space is explored. Recommendations are made for enhancing and upgrading the current RSP to provide an injured crew member with the best possible chance of survival.
