Effects of Inspiratory Pressure Preset on Alveolar Gas Exchange Using Anesthetic Ventilator

The study was undertaken to determine the most adequate tidal volume when used volume preset ventilator during anesthesia. The thirty patients were received controlled mechanical ventilation with constant inspiratory pressure of 10cmH2O and respiratory frequency of 12/minute. The results were as follows : 1) The PH was and it is within normal limit. 2) The was mmHg and it is a slightly hyperventilatory state. 3) The was mmHg. 4) The Buffer base was and it is a slightly buffer base deficient state. From the above results. We concluded that if patients were fully relaxed during general anesthesia, it is desirable to maintain the inspiratory pressure of anesthetic mechanical ventilator to for adeguate alveolar ventilation.
