Non-invasive positive pressure ventilation (NPPV) - also called non-invasive mechanical ventilation - uses gentle air pressure to mechanically assist or replace spontaneous breathing.
NPPV improves the effective exchange of gases and makes breathing easier, while also relieving the respiratory muscles.
Unlike invasive ventilation, which is delivered via an artificial airway, with NPPV air is delivered via a mask that covers the mouth and nose.
There are three types of respirator device for non-invasive positive pressure ventilation:
- volumetric (delivering by volume)
- barometric (delivering by pressure)
- combined (which deliver both by volume and pressure)
The respiratory specialist will recommend the right type of respirator according to the patient’s condition and the required settings which are tailored to their particular needs.
