Volume-targeted Versus Pressure-limited Noninvasive Ventilation in Patients With Acute Hypercapnic Respiratory Failure
May 21, 2019 updated by: Zujin Luo, Beijing Chao Yang Hospital
Volume-targeted noninvasive ventilation (VT-NIV), a hybrid mode that targets a preseted tidal volume (VT) by automated adjustment of pressure support, could guarantee the delivered VT over pressure-limited noninvasive ventilation (PL-NIV) with fixed level pressure support.
Whether VT-NIV is more effective in improving gas exchange in patients with acute hypercapnic respiratory failure (AHRF) as compared with PL-NIV remains unclear.
Our aim was to verify whether in comparison with PL-NIV, use of VT-NIV was more effective in correcting hypercapnia, hence reducing the need for intubation and improving survival in patients with AHRF.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Volume-targeted noninvasive ventilation
For Volume-targeted noninvasive ventilation, the target VT was set at 10 ml/kg of ideal body weight, with inspiratory positive airway pressure (IPAP) ranging from 10 cmH2O up to 25 cmH2O.
|
|
No Intervention: Pressure-limited noninvasive ventilation
For Pressure-limited noninvasive ventilation, IPAP was initially set at 10 cmH2O, and was adjusted by increments of 1-2 cmH2O according to patients' tolerance (up to 25 cmH2O) to obtain a VT of 8-10 ml/kg of ideal body weight and a respiratory rate (RR) less than 25 breaths/min.
