    Background And AimIntelligent volume-assured pressure support (iVAPS) is a relatively new hybrid mode of non-invasive ventilation (NIV). There is still limited evidence for iVAPS. The aim of this study was to compare the effectiveness of iVAPS to that of bi-level positive airway pressure spontaneous/timed (BPAP S/T) in patients with acute hypercapnic respiratory failure or acute-on-chronic hypercapnic respiratory failure caused by acute exacerbation of chronic obstructive pulmonary disease (AECOPD) in the emergency department.Material And MethodsThis was an observational, retrospective study. Eighty-two patients with hypercapnic respiratory failure caused by AECOPD, who were admitted to our emergency department, were analysed. Arterial blood gas (ABG) parameters, length of hospital stay and rate of intensive care unit (ICU) admission were compared between iVAPS and BPAP S/T.ResultsA total of 82 patients (26 females, 56 males, mean age 68.26 ± 11.63 years) who were treated with iVAPS (N = 26) or BPAP S/T (N = 56) were enrolled. There were no significant differences between two modes with respect to demographics such as age, gender, presence of comorbidity, usage of long-term oxygen therapy or NIV, and the baseline ABG parameters. The presence of pneumonia was significantly higher in BPAP S/T (P = .01). The rate of ICU admission was 26.9% in iVAPS vs 25% in BPAP S/T. The mean length of hospital stay was 11.5 ± 12.3 days in iVAPS and 9.7 ± 7.4 days in BPAP S/T (P = .53). The mean values of ABG parameters at the 1st and 24th hours of NIV therapy did not differ in both groups.ConclusionBoth modes were similarly effective in the management of appropriately selected patients with hypercapnic respiratory failure caused by AECOPD. Hence, we underline that NIV mode selection in the emergency department should be performed in line with experiences of clinicians/institutions and accessibility of ventilator devices/modes.© 2021 John Wiley & Sons Ltd.
