Detailed explanation-1: -Patients with underlying chronic obstructive pulmonary disease (COPD) who present with an exacerbation of their COPD and hypercapnic respiratory distress or respiratory failure are the group most likely to be successfully treated with noninvasive ventilation (NIV).
Detailed explanation-2: -NPPV is not appropriate for some patients, such as those with cardiopulmonary arrest or shock, where greater airway control is required, or facial trauma, where the interface (e.g., mask) cannot be used appropriately.
Detailed explanation-3: -Absolute contraindications for NIV are as follows: Respiratory arrest or unstable cardiorespiratory status. Uncooperative patients. Inability to protect airway (impaired swallowing and cough)
