The Impact

Reports of acute mountain sickness (AMS) at moderate altitude show a wide variability, possibly because of different investigation methods. The aim of our study was to investigate the impact of investigation methods on AMS incidence. Hackett's established AMS score (a structured interview and physical examination), the new Lake Louise AMS score (a self-reported questionnaire) and oxygen saturation were determined in 99 alpinists after ascent to 2.94 km altitude. AMS incidence was 8% in Hackett's AMS score and 25% in the Lake Louise AMS score. Oxygen saturation correlated inversely with Hackett's AMS score with no significant correlation with the Lake Louise AMS score. At moderate altitude, the new Lake Louise AMS score overestimates AMS incidence considerably. Hackett's AMS score remains the gold standard for evaluating AMS incidence.

1. The response of serum angiotensin converting enzyme (ACE) activity to three grades of hypoxia was studied in two groups of human subjects. Hypoxic gas mixtures having oxygen concentrations of 14, 12.6 and 10.4% were breathed successively for a period of 10 min at each concentration. Venous blood was sampled at the end of each of the three periods and arterial oxygen saturation was recorded throughout the experiment. 2. The subjects were selected as being ‘good’ or ‘poor’ acclimatizers according to their history of acute mountain sickness. There were five subjects in each group. 3. Hypoxia resulted in a reduction in ACE activity in both groups, the reduction being linear with respect to arterial oxygen saturation. 4. The reduction in ACE activity was greater in the good acclimatizer group as shown by a significantly greater slope of the response line of ACE activity to arterial oxygen saturation. 5. The significance of this finding in relation to the mechanism underlying acute mountain sickness is discussed.

Abstract The authors report a case of acute mountain sickness (AMS) experienced by a support member of the Ultima Thule Everest Expedition. The subject arrived at the 17,000-ft base camp by truck and then developed the symptoms of AMS over the following 72 hours. Flash-induced visual evoked responses (VERs), tetrapolar impedance pulmonary plethysmography, and oxygen saturation measurements were performed. These changed from normal before the onset of his symptoms to abnormal during the height of the symptoms and reverted to normal after treatment. This is the first reported case of AMS monitored with VERs. It has been postulated that AMS may be an early form of cerebral edema, and this report corroborates this hypothesis.
