Introduction

Non-invasive ventilation has revolutionized the management of acute and chronic respiratory failure in India, particularly gaining prominence during the COVID-19 pandemic when it reduced intubation rates and improved patient outcomes across diverse pathologies¹. The Indian Society of Critical Care Medicine (ISCCM) guidelines strongly recommend NIV for acute exacerbation of COPD with respiratory acidosis (pH 7.25-7.35), establishing evidence-based protocols for Indian ICUs.

In the Indian healthcare context, the transition of stable NIV patients from intensive care settings to home-based care has become both a clinical necessity and an economic imperative. With India's healthcare expenditure at 3.6% of GDP, significantly lower than developed nations, optimizing resource utilization while maintaining quality care is paramount. The COVID-19 pandemic accelerated home healthcare adoption, with telemedicine consultations increasing by 500% and home medical equipment demand rising substantially².

Current estimates suggest over 15,000-20,000 patients in India require long-term NIV support, with numbers growing annually due to increasing COPD prevalence, air pollution-related respiratory diseases, and improved survival rates from neuromuscular disorders³. However, India faces unique challenges including power supply inconsistencies, monsoon-related infrastructure issues, joint family dynamics affecting caregiver roles, and significant urban-rural healthcare disparities.

Indian critical care practitioners must navigate complex transitions involving not just clinical considerations but also cultural sensitivity, economic constraints, and infrastructure limitations. This review provides evidence-based guidance specifically adapted for the Indian healthcare ecosystem, incorporating ISCCM recommendations and addressing unique regional challenges.

Patient Selection Criteria

Clinical Stability Markers

Primary Criteria:

Stable gas exchange on consistent NIV settings for ≥48-72 hours
Absence of hemodynamic instability requiring vasoactive support
Resolution of acute precipitating factors
Demonstrated tolerance of NIV interruptions for activities of daily living

Pearl: The "3-Day Rule" - Patients should demonstrate consistent NIV requirements without setting adjustments for three consecutive days before considering home transition.

Diagnostic Categories Suitable for Home NIV in Indian Context

Excellent Candidates:

Chronic obstructive pulmonary disease with hypercapnic respiratory failure (most common indication in India)
Post-COVID pulmonary fibrosis with stable ventilatory requirements
Restrictive lung disease (chest wall deformities, poliomyelitis sequelae, common in India)
Central hypoventilation syndromes
Stable obesity hypoventilation syndrome (increasing prevalence in urban India)

Conditional Candidates (Require Enhanced Support):

Post-acute respiratory distress syndrome with prolonged ventilator dependence
Interstitial lung disease with stable gas exchange requirements
Sleep-disordered breathing with complex requirements
