Hypoxaemia in acute stroke is frequent and worsens outcome.

  Background: Hypoxaemia in the acute phase of stroke might damage the ischaemic penumbra and worsen clinical outcome. We determined the frequency of hypoxaemia on admission with stroke and assessed whether it was related to outcome. Methods: We measured arterial oxygen saturation (SaO2) and breathing effort with portable monitoring equipment in a large cohort of acute stroke patients, continually from arrival at hospital, during interdepartment transfer, in imaging and on the ward. Patients received best medical care according to current guidelines. Baseline neurological examination and 3-month outcome (Modified Rankin Scale) were assessed blind to other data. Hypoxaemia was defined as SaO2
