  1. RESP = respiratory system; CVS = cardiovascular system; HAEM = haematological system; GIT = gastro-intestinal system; CNS = central nervous system; RENAL = renal system;
  2. PaO2 = arterial partial pressure of oxygen (mmHg); FiO2 = fractional inspired oxygen; RA = room air; SBP = systolic blood pressure (mmHg); NA = noradrenaline; GCS = Glasgow Coma Scale; UO = urine output.
