Post Arousal Central Apnea

Arousal after event is a normal, it's an expected physiological response. Now is it contributing to the subsequent central apnea? Right. If I see a period of hyperventilation, and again, you need some time of thishyperventilation, think of we're decreasing the arterial CO2. That low CO2 has to travel all the way to the medulla. It needs somewhere between two to three minutes to get there. So if I see that pattern, which is what you see in chains to extra aspiration, then the arousal is contributing. But again, it all depends on how many of these were seen.
