Official title
Physiological Effects of Novel Noninvasive Ventilation Facemasks Favoring Carbon Dioxide Washout in Patients With Hypercapnic Respiratory Failure
Overview
The objective of this randomized cross-over trial is to assess the physiological effects of three different facemasks for noninvasive ventilation (Nivairo, Visairo, Optiniv) in patients with acute hypercapnic respiratory failure
Interventions
- Device Noninvasive ventilation
Respiratory support with a facemask connected to a ventilator through a heated humidifier. Ventilator will be set in the pressure support mode.
Primary outcome measures
- Metabolic work of breathing [Time frame: 45 minutes]
Secondary outcome measures (11)
- Normalized metabolic work of breathing [Time frame: 45 minutes]
- Inspiratory effort, expressed in cmH2O [Time frame: 45 minutes]
- Corrected minute ventilation [Time frame: 45 minutes]
- Dyspnea [Time frame: 45 minutes]
- Discomfort [Time frame: 45 minutes]
- End-expiratory lung volume [Time frame: 45 minutes]
- Regional End-expiratory lung volume [Time frame: 45 minutes]
- Arterial carbon dioxide, expressed in mmHg [Time frame: 45 minutes]
- Arterial acid-base state [Time frame: 45 minutes]
- Recuitment of expiratory muscles, expressed in cmH2O of gastric pressure [Time frame: 45 minutes]
- Tidal volume distribution [Time frame: 45 minutes]
