Key result
Manipulation of P(et)CO2 levels did not significantly alter the average increases in minute ventilation, heart rate, and blood pressure at arousal from sleep (all P > 0.05).
Why the study?
Does the level of P(et)CO(2) affect the magnitude of cardiorespiratory response at an arousal from sleep in normal young males?
Does the level of P(et)CO(2) affect the magnitude of cardiorespiratory response at an arousal from sleep in normal young males?
p-value: p=> 0.05
The cardiorespiratory response to an arousal from sleep is driven by reflex activation rather than a homeostatic response to CO2 levels.
No takes yet. Share an insight, caveat, or question.
Arousal cardiorespiratory responses appear CO2-independent in young males; hypothesis-generating for reflex mechanisms and requires confirmation before clinical application.
Trinder et al. (2006) studied Normal subjects. Manipulation of P(et)CO2 vs. Different levels of P(et)CO2 was evaluated on Average increases in minute ventilation, heart rate, and blood pressure at arousal from sleep (p=> 0.05). Manipulation of P(et)CO2 levels did not significantly alter the average increases in minute ventilation, heart rate, and blood pressure at arousal from sleep (all P > 0.05).
