Study Notes

Non-Invasive Positive Pressure Ventilation (NIPPV)

  • NIPPV stands for Non-Invasive Positive Pressure Ventilation

Indications for NIPPV

  • Type 1 (CPAP) and 2 (BIPAP) respiratory failure
  • Exacerbation of COPD (Chronic Obstructive Pulmonary Disease)
  • Atelectasis
  • Acute Pulmonary Oedema (Cardiogenic and non-cardiogenic)
  • Pneumonia
  • Ventilatory (pump) failure due to:
    • Chest wall deformity
    • Neuromuscular disease
  • Weaning from Invasive Mechanical Ventilation

Contraindications for NIPPV

  • Life-threatening hypoxemia (PaO2 < 60mmHg)
