*Fisher's exact test.
†Only 830 of the patients admitted were analysed.
‡Invasive mechanical ventilation, ventilatory support with patient intubated or tracheostomised.
BP, blood pressure; ICU, intensive care unit; NIV, non-invasive ventilator support with patient not intubated or tracheostomised; SpO2, saturation of peripheral oxygen measured by pulse oximetry.
