Detailed explanation-1: -Non-invasive positive pressure ventilation involves the delivery of oxygen into the lungs via positive pressure without the need for endotracheal intubation. It is used in both acute and chronic respiratory failure but requires careful monitoring and titration to ensure its success and avoid complications.
Detailed explanation-2: -NIV is particularly indicated in: COPD with a respiratory acidosis pH 7.25–7.35 (H+ 45–56 nmol/l) Hypercapnic respiratory failure secondary to chest wall deformity (scoliosis, thoracoplasty) or neuromuscular diseases. Cardiogenic pulmonary oedema unresponsive to CPAP.
Detailed explanation-3: -Non‑invasive ventilation is used to treat persistent hypercapnic ventilatory failure and acidosis during an exacerbation of COPD, when a person’s arterial blood gases (especially the pH and carbon dioxide levels) are not responding (or worsening) despite optimal medical management.
Detailed explanation-4: -Noninvasive positive-pressure ventilation is the delivery of mechanical ventilation to patients with respiratory failure without the requirement of an artificial airway.
