What is non-invasive home ventilation?
Home noninvasive ventilation (NIV) is frequently implemented to correct nocturnal alveolar hypoventilation in a number of chronic respiratory diseases. The most widely used ventilatory mode is pressure-support (PS) ventilation with a backup respiratory rate spontaneous timed (ST) mode.
Why is the NIV mask used?
Non-invasive ventilation (NIV) is the use of breathing support administered through a face mask, nasal mask, or a helmet. Air, usually with added oxygen, is given through the mask under positive pressure; generally the amount of pressure is alternated depending on whether someone is breathing in or out.
Why is non invasive ventilation used?
Noninvasive ventilation effectively unloads the respiratory muscles, increasing tidal volume, decreasing the respiratory rate, and decreasing the diaphragmatic work of breathing, which translates to an improvement in oxygenation, a reduction in hypercapnia, and an improvement in dyspnea.
How much oxygen is in the NIV?
The target of arterial oxygen saturation measured by pulse oximetry (SpO2) under NIV should be different in hypercapnic and hypoxaemic patients [33]. In cases of hypercapnic ARF treated with NIV, SpO2 targets should be 88–92%.
What is the difference between NIV and ventilator?
In invasive ventilation, air is delivered via a tube that is inserted into the windpipe through the mouth or sometimes the nose. In NIV, air is delivered through a sealed mask that can be placed over the mouth, nose or the whole face.
Is NIV better than ventilator?
Long-term survival. Three studies have suggested that the use of NIV is associated with a better 1‐yr survival compared to standard ICU therapy 33, 34 or invasive mechanical ventilation 35. The recent study of Conti et al. 21 confirms these findings.
How does NIV work in COPD?
NIV is used in nearly one third of COPD patients considered to have a poor life expectancy (71). Its use in this setting has a weak evidence base but used judiciously can contribute to symptom relief without adding to the care burden. NIV can relieve breathlessness by unloading the respiratory muscles.
Is NIV better than oxygen?
To date, few randomized controlled studies have found better outcomes with NIV than with standard oxygen (35,36). The heterogeneity of patients included in studies comparing NIV to standard oxygen, i.e., patients with hypercapnia or cardiogenic pulmonary edema, may explain high intubation rate variability (7,35-38).
Can NIV be given at home?
Long-term or home mechanical noninvasive ventilation (Home-NIV) has become a well-established form of therapy over the last few decades for chronic hypercapnic COPD patients in European countries. However, meta-analyses and clinical guidelines do not recommend Home-NIV for COPD patients on a routine basis.
