Respiratory Support for Pharmacologically Induced Hypoxia in Neonatal Calves

Figure 5

Arterial blood lactate concentration following respiratory support by oxygen insufflation or continuous positive airway pressure (CPAP). Values are shown as median (horizontal line) and mean (diamond) and quartiles and range immediately after catheter placement (T0, baseline), 10 minutes following sedation (T1, sedation), following 10 minutes of oxygen supplementation (O₂), following 10 minutes of CPAP, and after 10 minutes of breathing ambient air following respiratory support (T3, rest, and T5, recovery). A significant time effect was observed, as results obtained after sedation were significantly less than baseline (). Order of respiratory support (O₂ supplementation or CPAP) was randomly assigned and had no significant effect on response to O₂ supplementation or CPAP.
