Brief Summary:
Randomized multicenter non-inferiority trial comparing High flow nasal therapy (HFNT) versus Noninvasive ventilation (NIV) in patients with chronic obstructive pulmonary disease (COPD) and acute hypercapnic respiratory failure.

Condition or disease Intervention/treatment Phase
COPD Exacerbation Other: HFNT Other: NIV Not Applicable

Detailed Description:

The interventions will be delivered in Emergency Departments or Intensive Care Units.

The intervention under investigation will be High flow nasal therapy. Investigators will deliver HFNT to enrolled patients using any available device able to produce it. The flow will be initially set at 60 liters per minute and temperature at 37° C. The target will be an oxygen saturation (SpO2) of 88-92%. In case of patient not tolerating these settings, flow and temperature will be titrated to the maximum tolerated level. The intervention will last until one of the following conditions: 1) physician in charge decide to interrupt HFNT and start NIV because the patient shows signs of persisting worsening respiratory failure; 2) physician in charge decide to interrupt HFNT and perform endotracheal intubation and invasive mechanical ventilation because patient shows one or more of these conditions: respiratory arrest, respiratory pauses with loss of consciousness, psychomotor agitation making nursing care impossible, heart rate < 50 with loss of alertness, hemodynamic instability with systolic arterial blood pressure <70 mmHg, development of conditions requiring intubation either to protect the airway or to manage copious tracheal secretions, inability to tolerate the devices; 3) clinical improvement defined as all these conditions: normal mental status, hemodynamic stability, respiratory rate below 25 per minute, absence of activation of accessory respiratory muscles and paradoxical abdominal motion, no dyspnea arterial pH > 7.35, Arterial partial pressure of carbon dioxide (PaCO2) < 70 mmHg and Arterial partial pressure of oxygen (PaO2) > 55 mmHg with an inspired oxygen fraction (FiO2) < 0.35.

In case of temporary interruption of the intervention for any cause, patients should receive oxygen supplementation with Venturi mask with a target of SpO2 88-92%.The comparator will be non invasive ventilation (NIV). NIV must be delivered by full or oronasal mask. The ventilator settings will be decided according to the usual practice: maximal tolerated inspiratory pressure to obtain a measured or estimated expired tidal volume of 6-8 mL·kg-1 of body weight and a positive end expiratory pressure (PEEP) between 3 and 5 cmH2O. An interface rotational strategy will be allowed among only different types of masks.

The intervention will last until one of the following conditions: 1) physician in charge decide to interrupt NIV and perform endotracheal intubation and invasive mechanical ventilation because patient shows one or more of these conditions: respiratory arrest, respiratory pauses with loss of consciousness, psychomotor agitation making nursing care impossible, heart rate < 50 with loss of alertness, hemodynamic instability with systolic arterial blood pressure <70 mmHg, development of conditions requiring intubation either to protect the airway or to manage copious tracheal secretions, inability to tolerate the devices; 2) clinical improvement defined as all these conditions: normal mental status, hemodynamic stability, respiratory rate below 25 per minute, absence of activation of accessory respiratory muscles and paradoxical abdominal motion, no dyspnoea arterial pH > 7.35, Arterial partial pressure of carbon dioxide (PaCO2) < 70 mmHg and Arterial partial pressure of oxygen (PaO2) > 55 mmHg with an inspired oxygen fraction (FiO2) < 0.35.

In case of temporary interruption of NIV for any cause, patients should receive oxygen supplementation with Venturi mask with a target of SpO2 88-92%.

Arm Intervention/treatment
Experimental: HFNT
HFNT performed with any available device. The flow will be initially set at 60 liters per minute and temperature at 37° C. The target will be an oxygen saturation (SpO2) of 88-92%. In case of patient not tolerating these settings, flow and temperature will be titrated to the maximum tolerated level.
Other: HFNT
High flow nasal therapy

Active Comparator: NIV
NIV must be delivered by full or oronasal mask with any available ventilator. The ventilator settings will be decided according to the usual practice: maximal tolerated inspiratory pressure to obtain a measured or estimated expired tidal volume of 6-8 mL·kg-1 of body weight and a positive end expiratory pressure (PEEP) between 3 and 5 cmH2O. An interface rotational strategy will be allowed among only different types of masks.
Other: NIV
Noninvasive ventilation




Primary Outcome Measures :
  1. Arterial partial pressure of carbon dioxide (PaCO2) [ Time Frame: 2 hours after randomization ]

Secondary Outcome Measures :
  1. Dyspnea evaluated with Borg dyspnea scale [ Time Frame: 2 and 6 hours after randomization ]
    Borg dyspnea scale: this is a 12-point validated scale that rates patient's difficulty in breathing. It starts at number 0 where breathing causes no difficulty at all and progresses through number 10 where breathing difficulty is maximal

  2. Arterial partial pressure of carbon dioxide (PaCO2) [ Time Frame: 6 hours after randomization ]

Other Outcome Measures:
  1. Respiratory rate [ Time Frame: 2 and 6 hours after randomization ]
  2. Discontinuation of the interventions [ Time Frame: At 6 hours after randomization ]
    The inability of the patient to continue the treatment while there was still an indication for ventilatory support

  3. Overall discomfort related to the interface [ Time Frame: At 6 hours after randomization ]
  4. Presence of side effects [ Time Frame: At 6 hours after randomization ]
    I.e., complaining for noise or too high temperature of flow, claustrophobia, gastric distension, vomiting, sweating, tightness

  5. Rate of treatment failure [ Time Frame: At 6 hours after randomization ]
    defined as the presence of one or more of the following: arterial partial pressure of carbon dioxide (PaCO2) reduction, no change or reduction < 10 mmHg from baseline, worsening or no improvement in dyspnoea, respiratory rate > 30 breaths per minute, use of accessory respiratory muscles or paradoxical abdominal movement

  6. Rate of endotracheal intubation [ Time Frame: At 6 hours after randomization ]
    Number of patients requiring endotracheal intubation
