BREATHING APPARATUS FOR HYPOXIC PRE-ACCLIMATIZATION AND TRAINING

摘要

A Hand-held rebreather/breathing apparatus for high altitudepre-acclimatization and training. Air exhaled by a user is directedto a reservoir bag for cooling and condensate collection. Atinhalation negative pressure created a mixing chamber forces the airstored in the reservoir bag to pass via CO2 absorptionchamber where it mixes with a fresh portion of the ambient air thatinfluxes via orifice (s) communicating with this chamber. Baseline ofthe minimum oxygen concentration in inspired air can be pre-set bymeans of adjustment of the maximum volume of the reservoir bagand/or by means of altering of the diameter of one or a plurality oforifices for communiation of the ambient air. Biofeedback isprovided by a pulse oximeter that reflects the individual reactionto hypoxic air breathing and allows to optimize treatment for anindividual.
