Restoration of arterial oxygen tension in horses recovering from general anaesthesia.

Controlled mandatory ventilation results in better pulmonary function in horses as assessed by PaO2 , P(A-a)O2 and PaCO2 , an effect enhanced by an initial period of SV and still evident 1 h after standing. High PaO2 values may contribute to early recovery apnoea but this does not adversely affect outcome. The Summary is available in Portuguese - see Supporting Information.
