HAPO Bag
Results: Extreme Altitude Pulmonary Oedema presented in fully acclimatized, temporarily resident, mountain trained soldiers and also among native highlanders. HAPO Bag ensued dramatic improvement in the absence of oxygen. Extreme altitude presentation of HAPO with such findings has not been reported in literature earlier. Conclusion: HAPO cannot be prevented at extreme altitudes beyond 5500 m (18,000 ft) by scheduled pre-induction acclimatization, mountain training or prolonged stay at such altitudes. The dictum ‘Every day is a new day beyond 18,000 ft’ needs to be emphasized and due care needs to be taken in ventures at extreme altitudes. HAPO Bag is an indispensable device to save precious lives and prolong survival at such altitudes due to paucity of available oxygen. Easy availability and universal know how should be ensured. ª 2012, Armed Forces Medical Services (AFMS). All rights reserved.
