BACKGROUND The level of environmental hypobaric hypoxia that affects climbers at the summit of Mount Everest (8848 m [29,029 ft]) is close to the limit of tolerance by humans. [] Key Method The partial pressures of arterial oxygen (PaO(2)) and carbon dioxide (PaCO(2)), pH, and hemoglobin and lactate concentrations were measured. The arterial oxygen saturation (SaO(2)), bicarbonate concentration, base excess, and alveolar-arterial oxygen difference were calculated.

Acute hypoxia in a simulated high-altitude airdrop scenario due to oxygen system failure.

This is the first study to investigate physiology and clinical outcome of oxygen system failure in a simulated HAHO scenario and the arterial oxygen tensions reported are among the lowest ever reported during acute hypoxia.

Systemic oxygen extraction during exercise at high altitude

In acclimatized individuals at 4559 m, there was a decline in maximum absolute C(a−v)O2 during exercise but no alteration in OER calculated using central venous oxygen measurements, suggesting that oxygen extraction may have become limited after exposure to 7–8 days of hypoxaemia.

Steady-state cerebral blood flow regulation at altitude: interaction between oxygen and carbon dioxide

A novel stimulus index (SI) was developed, taking into account both chemostimuli (PaCO2/SaO2), and CBF was indexed against the SI to assess steady-state cerebrovascular responsiveness (SS-CVR).

Extreme hypoxemic tolerance and blood oxygen depletion in diving elephant seals.

The data suggest that elephant seals routinely tolerate extreme hypoxemia during dives to completely utilize the blood O(2) store and maximize aerobic dive duration.

Enhanced muscular oxygen extraction in athletes exaggerates hypoxemia during exercise in hypoxia.

This study shows that maintenance of high muscular oxygen extraction rate at very low circulating PaO2 stimulates the development of hypoxemia during submaximal exercise in hypoxia in endurance-trained individuals, which may predispose to premature development of acute mountain sickness symptoms during exercise at altitude.

Assessment of arterial blood gases in Hypobaryk and comparison with normal Raptor fighter pilots

This research examined the Mountaineers to a metabolic alkalosis due to the hypoxia caused by Hypo ventilated with Kmvrsptvr stimulation was observed, and changes in the elevation of arterial blood gases is limited.

High-Altitude Research and Its Practical Clinical Application

The tolerance to hypoxia formula reflects and explains the paradoxical concept that resistance to Hypoxia grows as one goes higher and the knowledge of life at high altitude is proposed as an alternative to the environment of space travel.

Validation of a Pulse Oximetry System for High-Altitude Waterfowl by Examining the Hypoxia Responses of the Andean Goose (Chloephaga melanoptera)

It is concluded that the MouseOx Plus pulse oximetry system can be a valuable tool for studying the cardiorespiratory physiology of waterfowl without the deleterious effects of surgery/cannulation.

Association Between Arterial Blood Gas Variation and Intraocular Pressure in Healthy Subjects Exposed to Acute Short-Term Hypobaric Hypoxia

Hypobaric hypoxia triggers plasma bicarbonate ion reduction which, rather than pH, may decrease aqueous humor formation and subsequently cause IOP reduction, which may shed light on the mechanism of IOP regulation at high altitude.



Operation Everest II: oxygen transport during exercise at extreme simulated altitude.

The findings suggest that although glycogenolysis may be accentuated at low work loads, it may not be maximally activated at exhaustion, and with increasing altitude, blood lactate was progressively reduced at maximal exercise, whereas at any absolute and relative submaximal work load, blood latate was higher.

A strategy for determining arterial blood gases on the summit of Mt. Everest

It is concluded that automatic arterial blood sampling at high altitude is technically feasible and that the changes in the blood gases over a period of several hours are acceptably small.

Pulmonary gas exchange in humans exercising at sea level and simulated altitude.

This study confirms the development of both VA/Q mismatch and DIFF in normal subjects during heavy exercise at sea level, however, the mechanism of increased VA/ Q mismatch on exercise remains unclear due to the correlation with both ventilatory and circulatory variables and will require further study.

The results help to explain how man can reach the highest point on earth while breathing ambient air by falling considerably at the lowest values of inspired PO2.

Supplemental oxygen effects on ventilation in acclimatized subjects exercising at 5700 m altitude.

An open-circuit breathing system may increase SaO2 and reduce RR in acclimatized mountaineers during rest and sub-maximal exercise at 5700 m, though further research is needed to confirm this.

Pulmonary gas exchange in humans during normobaric hypoxic exercise.

The multiple inert gas elimination technique was used to compare gas exchange during exercise under normobaric hypoxia with earlier hypobaric measurements and VA/Q inequality increased significantly during hypoxic exercise.

Diffusion limitation in normal humans during exercise at sea level and simulated altitude.

Expected and actual PaO2 agreed during 100% O2 breathing at 15,000 ft, excluding postpulmonary shunt as a cause of the larger alveolar-arterial O2 difference than accountable by inert gas exchange, indicating alveolars-capillary diffusion disequilibrium for O2.

An integrated picture of human gas exchange at the highest point on earth is constructed for the first time due to the severe arterial hypoxemia, high pH, and extremely low PCO2 of subjects on the summit of Mt. Everest.

Operation Everest II: man at extreme altitude.

To examine changes in the O2 transport system that produce acclimatization, eight men were taken in a decompression chamber to a simulated altitude of 8,840 m (29,028 ft, ambient PO2 = 43 Torr) in 40 days and normal cardiac function persisted, pulmonary vascular resistance increased and at extreme altitude was not lowered by O2, and pulmonary ventilation-perfusion mismatch increased, though variably.

The relative value of HVR in the group of climbers was not significantly altered after acclimatization; HVR predicts exercise ventilation at sea level and high altitude; the drop in Sao2% that occurs with exercise is inversely related to HVR; and sojourners with high HVR may perform better at extreme altitude.
