Propofol has which effect on respiration?

Explanation:
Propofol decreases respiratory drive by depressing the central respiratory center and blunting the ventilatory response to CO2. This leads to a dose-dependent reduction in both tidal volume and respiratory rate, resulting in lower minute ventilation. In practice, this means patients can become hypoventilated and, with rapid bolus induction or when combined with other sedatives or opioids, apnea can occur. So the net effect is a diminished ventilatory drive, not an increase in breathing rate or tidal volume, and not no effect on ventilation.
