An electronic system was developed that: computes the oxygen consumption rate of a human subject while breathing room air; measures the flow rate of the expired air, expired air minute volume, tidal volume, arterial blood pressure, and pulse rate; and records the electrocardiogram. The flow rate of the expired air and the fraction concentrations of the CO2 and O2 in the expired air are measured with electronic gas analyzers and then electronically computed to give a continuous analog record of the oxygen consumption rate. All of the variables are continuously recorded in analog form. The average values of oxygen consumption rate, arterial blood pressure, or expired air minute volume and pulse rate are recorded in digital form with print out every minute. analog computer analysis of O2 consumption; continuous analog recording of expired airflow rate and minute volume, tidal volume, arterial blood pressure, and pulse rate; analog-to-digital conversion of O2 consumption, arterial blood pressure, pulse rate, and expired air minute volume; continuous recording of O2 consumption for subject breathing air; continuous electronic computation of O2 consumption Submitted on June 24, 1963
