9 Questions
What is an indication for NIPPV in patients with respiratory failure?
Type 1 (CPAP) and Type 2 (BIPAP) respiratory failure
What is an example of a condition that may require NIPPV?
Atelectasis
What type of respiratory failure is an indication for NIPPV?
Type 1 (CPAP) and 2 (BIPAP) respiratory failure
NIPPV Contraindications
Life-threatening hypoxemia (PaO2 <60mmHg
on FiO2 100%)
• Respiratory arrest
• Untreated pneumothorax
• Life-threatening dysrhythmias
• Inability to protect own airway
• Copious, unmanageable respiratory secretions/
vomiting
• Haemodynamic Instability
• Facial burns/trauma/recent facial or upper
airway surgery
Fick’s Law – Law of diffusion
Surface area • Concentration difference • Thickness of the barrier
How does PEEP (positive end-expiratory pressure) affect preload?
PEEP decreases preload
What is the effect of PEEP on right ventricular afterload?
Increased
What is the effect of PEEP on left ventricular afterload?
Decreased
PEEP Respiratory Effects
Increases gas exchange; Recruits collapsed alveoli / improves atelectasis–Reduces V/Q mismatch
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)
