Niet-invasieve respiratoire ondersteuning bij acute respiratoire insufficiëntie

• Conventional oxygen therapy could be delivered via nasal prongs, face mask, venturi mask, or non-rebreather mask.
• High flow nasal cannula (HFNC) produces a higher flow of FiO₂. This higher flow creates a positive pressure on the higher respiratory tract. Collapsed alveoli could be opened due to this positive pressure and CO₂ would be eliminated. This improves the oxygenation and reduces the total work of breathing.
• Continuous positive pressure support (CPAP) realizes a continuous positive expiratory pressure to the respiratory tract, which opens the alveoli and reduces the pre-load by reducing the venous return.
• Non-invasive ventilation (NIV) improves ventilation and reduces the work of breathing.
• Initiating use of HFNC, CPAP or NIV can prevent intubation but the response should be carefully evaluated after 1-2 hours to not delay intubation.
