Table 3 Mortality rate, length of stay and incidence of complications associated with noninvasive positive pressure ventilation

From: Performance of noninvasive ventilation in acute respiratory failure in critically ill patients: a prospective, observational, cohort study

Variables NIV failure 26 (30.6 %) NIV success 59 (69.4 %) P value
Length of ICU stay (days) 12 [8–31] 2 [1–4] <0.001a
Length of hospital stay (days) 30 [19–42] 15 [9–33] 0.010a
Mortality at day 28, n° (%) 5 (19.2) 4 (6.8) 0.124b
In-hospital mortality, n° (%) 10 (38.5) 7 (11.9) 0.008b
Complications associated with NIV    
Gastric distension 3 (11.5) 4 (6.8) 0.670b
  1. ¶ = p values for NIV failure vs. NIV success Groups. a = Mann–Whitney U test, b = Fisher’s exact test and. ICU Intensive care unit. Values are median [IQR] or n° (%) when indicated
