Effect of Intermittent Positive Pressure Ventilation on Depth of Anaesthesia during and after Isoflurane Anaesthesia in Sulphur-Crested Cockatoos (Cacatua galerita galerita)

Table 7

Mean time ± SD for the return of spontaneous breathing in 6 sulphur-crested cockatoos (Cacatua  galerita galerita) during recovery from 1.5% and 3.0% isoflurane anaesthesia after intermittent positive pressure ventilation (IPPV).

IPPV rate; (breaths/minute)	Time for return of spontaneous ventilation (s)
	1.5% isoflurane	3.0% isoflurane
6	11 ± 8 (3)	17 ± 3 (3)
12	38 ± 22	53 ± 23

Numbers in parentheses indicates the number of birds that developed apnoea.
