Physical Fitness and Human Tolerance to Acute Exposure to Life at High Altitude. Experimental Design and Data Processing Methodology for Clinical Physiological Observations

摘要

A description is given of the methods by which measurements of various physiologic changes during exposure to altitude were collected. The type of log books which were kept are described in detail. The data processing system had five stages: (1) Chronological logging of raw data in separate log books; (2) preparation of edited input data sheets and data cards; (3) Computer output and human editing of data output cards; (4) Computer output and human editing of summary output cards; (5) computer output and final human interpretation of P and F values for significance of the results obtained.
