* T-values were calculated using Paired Samples T-test (between departure and arrival).
** P-values were calculated using the McNemar test (between departure and arrival).
Heart rate and respiratory rate is beats per minute respectively breaths per minute. Systolic, diastolic blood pressure (BP) and MAP (mean arterial pressure) are expressed as mmHg. Laboratory values (bicarbonate, haemoglobin, lactate and glucose) are expressed as mmol/L.
PaO2, partial arterial oxygen tension; PaCO2, Partial arterial carbon dioxide tension.
