Anesthetist, Toledo, O.
THE IMPORTANCE of respiration to the anesthetist as a sign of the patient's condition can scarcely be overestimated. Clinical experience has shown that certain efficiency of respiration is essential to the well-being of the anesthetized patient, just as it is to the cardiac case of the internist. Unfortunately, however, too much attention has been given to the rate of respiration, none to the minute-volume and but little more to the tidal volume. Perhaps the ease of counting respiration and the great strides made in other fields of medicine have retarded general interest in the more accurate observations of other phases of respiration.
Neither the rate nor the volume of tidal respiration taken separately determines the efficiency of the respiratory function. Both are essential. That is. pulmonary ventilation -the minute volume -or the amount of gases inhaled per minute determines the efficiency of the patient's breathing.
