Determination of oxygen saturation compared to a prescribed target range using continuous pulse oximetry in acutely unwell medical patients

Table 2 Oxygen delivery and prescribed target range at enrolment

Characteristic
Target SpO₂ range	N/80 (%)
92–96%	41 (51.3)
Reduced hypercapnic^a	34 (42.5)
Non-standard	5 (6.3)
Method of oxygen delivery at enrolment	N/80 (%)
Simple nasal prongs	64 (80)
Nasal high-flow	16 (20)
Delivered oxygen at enrolment	Mean (SD)
Simple nasal prongs (L/min)	1.6 (0.8)
Nasal high-flow (%)	32.3 (6.3)
Nasal high-flow (L/min)	36.5 (3.7)

^aThis group comprised the 28 participants with a target range of 88–92% and six patients with a non-standard target range which was lower than 88–92%. These ranges were 85–90%, 86–92%, 85–92%, 80–92% and two participants with 80–85%
