Treatment

COPD Exacerbation

Bilevel NIV may be considered in COPD patients with an acute exacerbation in three clinical settings:
  1. To prevent acute respiratory acidosis — i.e., when the arterial CO2 tension (PaCO2) is normal or elevated but pH is normal.
  2. To prevent endotracheal intubation and invasive mechanical ventilation in patients with mild to moderate acidosis and respiratory distress, with the aim of preventing deterioration to a point when invasive ventilation would be considered.
  3. As an alternative to invasive ventilation in patients with severe acidosis and more severe respiratory distress.
Bilevel NIV may also be used as the only method for providing ventilatory support in patients who are not candidates for or decline invasive mechanical ventilation.
We suggest NIV NOT be used in patients with hypercapnia who are not acidotic in the setting of a COPD exacerbation. (C, L)

We recommend bilevel NIV for patients with acute respiratory failure (ARF) leading to acute or acute-on-chronic respiratory acidosis (pH ≤7.35) due to chronic obstructive pulmonary disease (COPD) exacerbation. (S, H)
620
We recommend a trial of bilevel NIV in patients considered to require endotracheal intubation and mechanical ventilation, unless the patient is immediately deteriorating. (S, M)
  1. Bilevel NIV2 should be considered when the pH is ≤7.35, PaCO is >45 mmHg and the respiratory rate is >20–24 breaths/min despite standard medical therapy.
  2. Bilevel NIV remains the preferred choice for patients with COPD who develop acute respiratory acidosis during hospital admission. There is no lower limit of pH below which a trial of NIV is inappropriate. However, the lower the pH, the greater risk of failure, and patients must be very closely monitored with rapid access to endotracheal intubation and invasive ventilation if not improving.

Cardiogenic Pulmonary Edema

We recommend either bilevel NIV or CPAP for patients with ARF due to cardiogenic pulmonary edema. (S, M)
620
We suggest that CPAP or bilevel NIV be used for patients with ARF due to cardiogenic pulmonary edema in the pre-hospital setting. (C, L)
620

Acute Asthma

Given the uncertainty of evidence we are unable to offer a recommendation on the use of NIV for ARF due to asthma. (, )
620

Immunocompromise

We suggest early NIV for immunocompromised patients with ARF. (C, M)
620

De Novo ARF

Given the uncertainty of evidence we are unable to offer a recommendation on the use of NIV for de novo ARF. (, )
620

Post-Op

We suggest NIV for patients with post-operative ARF. (C, M)
620

Palliative Care

We suggest offering NIV to dyspneic patients for palliation in the setting of terminal cancer or other terminal conditions. (C, M)
620

Chest Trauma

We suggest NIV for chest trauma patients with ARF. (C, M)
620

Pandemic Viral Illness

Given the uncertainty of evidence we are unable to offer a recommendation for the use of NIV in ARF due to pandemic viral illness. (, )
620

Following Extubation

We suggest that NIV be used to prevent post-extubation respiratory failure in high-risk patients post-extubation. (C, L)
Remark: Patients with unplanned extubation are a higher risk group, and further studies are needed to address the use of NIV in this group.
620
We suggest that NIV should NOT be used to prevent post-extubation respiratory failure in non-high-risk patients. (C, VL)
620
We suggest that NIV should NOT be used in the treatment of patients with established post-extubation respiratory failure. (C, L)
Remark: This recommendation may not apply to post-extubation CHF or COPD patients with respiratory failure; further studies are needed.
620

Weaning

We suggest NIV be used to facilitate weaning from mechanical ventilation in patients with hypercapnic respiratory failure. (C, M)
620
We do not make any recommendation for hypoxemic patients. (, )
