% (n/Na)

Hypotension (BP < 90 mmHg systolic)

53 % (28/53)

35 % (19/54)

Hypoxia (PO2 < 11 kPa//SAT < 92 %)

57 % (31/54)

33 % (18/54)

Anaemia (Hgb ≤ 10 g/dl)

56 % (30/54)

17 % (9/53)

Hyponatremia (Na ≤ 135 mmol/l)

19 % (10/54)

15 % (8/53)

Hyperglycaemia (Gluc ≥ 8 mmol/l)

65 % (35/54)

38 % (15/40)

  1. aLower numbers for some patients because physiological variable is not measured or observation chart not available/missing
  2. BP blood pressure, PO2 oxygen partial pressure, SAT oxygen saturation, Body tp body temperature, Hgb blood haemoglobin, Na serum sodium, Gluc blood glucose
