Pneumatometry
Historical document, translated for reference. It reflects medical knowledge of the 1920s–30s and is not medical advice.
Summary
Pneumatometry is a method for measuring the strength of inhalation and exhalation using a U-shaped mercury manometer. The procedure requires isolating the respiratory muscles to prevent the cheek muscles from influencing the pressure readings.
Encyclopedia entry (1928–1936)
PNEUMATOMETRY, a method of measuring the strength of inhalation and exhalation. The instrument for pneumatometry—the pneumatometer—consists of a U-shaped glass manometer tube filled halfway with mercury. Each branch of the manometer is equipped with a scale. To determine the strength of inhalation, air is drawn from the pneumatometer, as a result of which the mercury in one limb drops and in the other rises. When measuring the strength of exhalation, one blows into the tube of the pneumatometer. It is very important, and must be monitored, that the muscles of the oral cavity (buccinator muscle) do not take part in this, but only the respiratory muscles.
