Question

8) What advantages does the nasal mask have over the full- face mask during the administration of NIV? not respond to conventional pharmacologic and oxygen therapy, what types of NIV have been shown to be effective? 10) What can be used to reduce gastric insufflation caused by high pressures during the use of NIV?
8,9,10

Answer 1

8, Noninvasive ventilation for ventilatory support in long term settings using nasal mask cause less skin problem, eye irritation and dryness, avoid air leak, it provide higher pressure comparing to the full face mask.
9, Cardiogenic pulmonary edema increases extravascular lung water and reduces lung volume, increases airway clearance and respiratory system compliance. It increases the lung's breathing workload for oxygen. Positive airway pressure restores the functional capacity and improves oxygenation. continuous positive airway pressure reduce dyspnea and it balances the inspiration load.NIV delivery with the use of PSV and PEEP, Bilevel positive airway pressure(BiPAP), inspiratory positive air pressure(IPAP), expiratory positive airway pressure(EPAP) is NIV produce pressure between EPAP and IPAP.it improve oxygenation in case of cardiogenic pulmonary edema.
10, High-pressure NIPSV(20 to 40cm H20 in controlled mode high-intensity NIPSV reduces cardiac output and benefit of tracheal gas insufflation.
