[455] ULTRA-COMPACT ANESTHETIC GAS INHALATION AID DEVICE FOR ZERO GRAVITY AND MULTIGRAVITATIONAL ENVIRONMENTS

摘要

INTRODUCTION: Inhaled gas anesthesia can be modulated by ventilation, which is safer and more comfortable than intravenous anesthesia. Inhaled anesthetics are non-flammable and can be recycled. The device is simple and compact, ideal for space. A new 3D printable device was developed, has the three key functions of general inhaled anesthesia machine (vaporizer, scavenger, ventilator). This anesthesia system can be safely operated and used in zero gravity environments. METHODS: The experiment was conducted using a hard container that had an external activated carbon filter to prevent an anesthetic gas leak. The system was tested on-board a modified MU-300 used for parabolic flights. Air was pushed through the system into an artificial lung and cleaned by an internal filter. 5cc of isoflurane and sevoflurane were vaporized independently into the system.
