normoventilation

normoventilation

[-ven′tilā′shən]
the alveolar ventilation rate that produces an alveolar carbon dioxide pressure of about 40 mm Hg at any metabolic rate.

The patients were randomized to one of the following two treatment sequences: hyperventilation followed by normoventilation or normoventilation followed by hyperventilation during isoflurane or propofol anesthesia, respectively.
In addition, the patients were randomized to one of the following two treatment sequences: Hyperventilation (to increase tidal volume [10-12 ml/kg] and respiratory rate [12-15/min] properly to maintain the PaCO [sub]2 = 27 [+ or -] 2 mmHg) followed by normoventilation (to maintain the normal tidal volume [8-10 ml/kg] and respiratory rate [10-12/min] in order to reach PaCO [sub]2 = 37 [+ or -] 2 mmHg) or vice versa during isoflurane or propofol anesthesia, respectively.
The sequence of the administration of isoflurane and propofol anesthesia and the sequence of hyperventilation and normoventilation studied here were randomized to eliminate any effect of time on the measurements.
The mean value of the SjO [sub]2 significantly decreased, and the O [sub]2 ER significantly increased under isoflurane or propofol anesthesia during hyperventilation compared with those during normoventilation (SjO [sub]2 : t = -2.
For a better understanding of ventilation management in neurosurgical anesthesia, the jugular bulb gases were measured under isoflurane anesthesia in comparison with the total intravenous anesthesia (TIVA) using propofol, during which patients were ventilated to maintain moderate hyperventilation followed by normoventilation or normoventilation followed by hyperventilation.
First, our results found that no significant changes in the SjO [sub]2 and O [sub]2 ER were observed under propofol anesthesia compared with isoflurane during normoventilation in the study.
Second, our results demonstrated that the SjO [sub]2 mean value significantly decreased and the O [sub]2 ER significantly increased during hyperventilation compared with those during normoventilation, regardless of whether isoflurane or propofol anesthesia was administered.
