All values are expressed as numbers (percentages) or median (interquartile range). Shock index: heart rate/systolic blood pressure. Vasopressors used for sustaining blood pressure were either noradrenaline or dopamine. APACHE: acute physiology and chronic health evaluation; CTPA: computer tomography pulmonary angiography; PA: pulmonary artery; PaCO2: partial pressure of carbon dioxide; PaO2: partial pressure of oxygen; PE: pulmonary embolism.
