Retrospective analysis of causes and outcome of dogs with hypoxaemia based on SpO ₂ or PaO ₂ measurements at the time of presentation to a referral hospital: 105 cases

Lower SpO₂ and PaO₂ values at presentation are not a negative prognostic indicator. Provision of antibiosis prior to referral of a hypoxaemic patient did not provide a survival or improved outcome advantage. Brachycephalic breeds do not have a worse prognosis.
