How CGHS, ECHS, and ESIC handle home oxygen concentrator and BiPAP reimbursement in India: rate ceilings, prescription requirements, GST treatment, and rejection causes.
GOLD-stage COPD and the LTOT prescription pathway
How GOLD staging maps to long-term oxygen therapy decisions, what the PaO2 thresholds actually mean, and how Indian dealer-channel reality shapes the prescription.
GST, import duty, and import-vs-domestic math for respiratory equipment
How GST and import duty stack up on CPAPs, BiPAPs, and oxygen concentrators in India — and what the price gap to US/EU street price actually buys you.

Hospital channel vs online channel for respiratory equipment in India
When buying CPAP, BiPAP, and oxygen concentrators through a hospital channel makes sense vs ordering online — price premium, service, GST, and warranty differences.
Hypercapnic respiratory failure: when BiPAP becomes the right answer
Why hypercapnic respiratory failure needs BiPAP rather than CPAP or oxygen alone, the mode-selection logic across S, S/T, and AVAPS, and the home NIV transition pathway.
