II. PHYSIOLOGIC OBSERVATIONS AND METHODS

Some physiologic observations in smoke inhalation.

Six persons were overcome by smoke inhalation when they were trapped within an elevator of a burning building. Evidence of bronchospasm as determined by spirometric examination was found in all six, but the only three who exhibited wheezing reported preexisting asthmatic conditions. An elevated carboxyhemoglobin was found in all. Three patients had metabolic acidosis but this finding did not co...

Video methods for evaluating physiologic monitor alarms and alarm responses.

False physiologic monitor alarms are extremely common in the hospital environment. High false alarm rates have the potential to lead to alarm fatigue, leading nurses to delay their responses to alarms, ignore alarms, or disable them entirely. Recent evidence from the U.S. Food and Drug Administration (FDA) and The Joint Commission has demonstrated a link between alarm fatigue and patient deaths...

A new physiologic race

Physiologic Response to Increased Oxygen Partial Pressure. Ii. Respiratory Studies.

The respiratory effects of a 30-day exposure to an alveolar partial pressure of 171 ram. Hg have been studied in 4 subjects at a total pressure of 700 ram. Hg (33.3 per cent 02 ) and 4 subjects at 258 mm. Hg (100 per cent oxygen). Vital capacities decreased on ascent to the 258 ram. Hg pressure ahitude and returned to normal immediately upon descent to ground level. Maximum breathing capacities...

Physiologic response to subgravity. II. Initiation of micturition.

T HE development of rocket .boosters and fuels c,~pable of high orbital payloads, including manned space probes, has drawn attention to the immediate application of biologic studies in the weightless state. The meager evidence available from the dog in Sputnik II encourages us to believe that the 'human organism can endure zero gravity, but complications may arise from prolonged exposure. Atten...
