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]

Eligibility criteria

Inclusion criteria

Acute respiratory failure with

  • Signed written informed consent

Exclusion criteria

  • Respiratory rate < 12 bpm;

  • Any contraindications to oesophageal balloon insertion and/or electrical impedance tomography (EIT) belt placement.
  • Any contraindications to facemask noninvasive ventilation.

Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.
