After educating the health care team about the importance of avoiding hypocapnia and the optimal way of selecting ventilator settings, we observed a significant decrease in variation of the first arterial PCO2 obtained after delivery (Figure 4).
2], still at the lower wake level, is sensed as relative hypocapnia and triggers marked ventilatory inhibition.
In the first 24 hr after injury, hypocapnia, hypotension, hyperglycemia, hypoxia, acidosis, intracranial hypertension, and seizures may all occur (Jeremitsky, Omert, Dunham, Protetch, & Rodriguez, 2003).

In addition to the changes in tidal volume, a rise in minute ventilation at altitude (up to 29%) will lead to hypocapnia, which may cause a shift of the oxyhaemoglobin dissociation curve to the left, hypokalaemia and decreased cerebral blood flow (11).
Extracranial causes include events such as hypotension, hypoxia, hypocapnia, and hyperglycemia (Chesnut et al.
