Indications
- respiratory failure due to
- COPD exacerbation
- heart failure
- cardiogenic pulmonary edema
- may decrease mortality[1]
- obesity hypoventilation syndrome
- neuromuscular disease
- immunosuppression
- non-invasive ventilation is associated with lower mortality & length of ICU stay in immunocompromised patients[1]
- postoperative hypoxemia[9]
- step down from mechanical ventilation (immediately following endotracheal extubation) in patient who tolerated a weaning trial
Contraindications
- medical instability
- cardiopulmonary arrest
- severe respiratory acidosis (pH < 7.0 or < 7.25 with failure to improve within 1.2 hours)[1]
- hemodynamic instability
- cardiogenic shock
- life-threatening cardiac arrhythmia
- upper gastrointestinal bleeding
- unable to protect airway
- excessive secretions, inability to clear secretions
- severe bulbar dysfunction
- recent gastrointestinal surgery
- altered mental status
- excessive somnolence or encephalopathy
- uncooperative or agitated patient
- airway obstruction
- unable to fit mask or large air leak
- recent facial trauma or surgery
- facial deformity[1]
- NPPV does not prevent re-intubation
- not for use as step down in patients who fail a weaning trial
Benefit/risk
- acute pulmonary edema[4]
- number needed to treat (NNT) = 13 to save 1 life
- number needed to treat (NNT) = 8 to prevent 1 endotracheal intubation[4]
- no harms identified[4]
- COPD exacerbation[5]
- number needed to treat (NNT) = 8 to save 1 life
- number needed to treat (NNT) = 5 to prevent 1 endotracheal intubation[5]
- no harms identified[5]
Procedure
- no weaning necessary [10)
- 3 additional nights of NPPV did not benefit patients with COPD exacerbation who met clinical criteria for unassisted breathing[10]
Complications
- may worsen outcomes by excessively delaying, rather than preventing endotracheal intubation
- failure to respond to NPPV with 1-2 hours is an indication for endotracheal intubation[1]
- positive pressure may diminish venous return
- bedside ultrasound to assess vena cava dimensions predicts responsiveness to volume replacement eliminating need for pulmonary artery catheter[1]
- not an aerosol-generating procedure[14]
Notes
- provides ventilatory support in addition to continuous positive airway pressure
- NPPV is time intensive & requires trained personnel[1]
- helmet noninvasive ventilation confers lower risks for mortality & endotracheal intubation than Venturi mask noninvasive ventilation[12]
- Venturi mask noninvasive ventilation confers lower risks for mortality & endotracheal intubation than high-flow nasal oxygen or standard nasal oxygen[12]
