Burns & Trauma

Table 4 Comparison of ventilation parameters in burn patients with and without inhalation injury

Parameter	No inhalation injury	Inhalation injury	P-value
Ventilator rate (breaths·min⁻¹)	17.0 (14.5–19.4)	17.8 (16.2–19.4)	0.513
Spontaneous rate (breaths·min⁻¹)	19.3 (15.4–23.2)	15.6 (11.1–20.0)	0.203
Ventilator tidal volume (ml/kg)	8.71 (6.86–10.56)	7.81 (6.84–8.78)	0.304
Spontaneous tidal volume (ml/kg)	9.55 (7.87–11.2)	7.63 (6.02–9.24)	0.085
Minute volume (L·min⁻¹)	10.5 (8.00–13.0)	11.3 (9.17–13.5)	0.597
Inspiratory pressure* (kPa)	2.42 (1.49–3.35)	2.90 (2.58–3.24)	0.118
ASB† pressure (kPa)	1.22 (1.06–1.36)	1.50 (1.19–1.81)	0.147
Peak airway pressure* (kPa)	2.15 (1.84–2.46)	2.63 (2.28–2.96)	0.048
Positive end expiratory pressure (kPa)	0.68 (0.55–0.85)	0.76 (0.67–0.85)	0.292
Inspired O₂ concentration (%)	37.9 (31.4–44.4)	47.5 (40.2–54.9)	0.052

Values are mean (95% confidence interval): P-value calculated with two-tailed t-test. *Inspiratory pressure applies during pressure controlled ventilation mode only. Peak airway pressure applies during volume controlled and spontaneous ventilation modes only. ^†ASB = Assisted spontaneous breathing.
