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

From: Ventilation strategies in burn intensive care: A retrospective observational study

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
  1. 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.
