About HHZ Respiratory Review
HHZ Respiratory Review catalogues the home-respiratory equipment sold in India — oxygen concentrators, CPAP machines, BiPAP devices, and nebulizers — and scores every device against the same published rubric. We lead with specifications, measure what we can on a bench, and document every claim against the source it came from.
What we do
We cover the consumer end of respiratory medicine in India: the devices patients take home after a GOLD-stage COPD diagnosis, a polysomnography-confirmed obstructive sleep apnea result, a post-acute hypoxia discharge, or a neuromuscular ventilation workup. Each review starts with manufacturer specs, verifies them against the device nameplate and service manual where available, and — for equipment we can get hands on — adds bench measurements (purity at multiple flow rates, sound pressure at one metre, pressure accuracy via calibrated manometer, leak compensation under load). The measurement protocol is documented in full on our methodology page.
Why we publish the rubric
Most of the top search results for "best oxygen concentrator India" today are written by retailers who also sell the devices, scored against criteria the reader never sees. The result is a flood of near-identical "top 10" lists that reshuffle the same six products without telling you why any of them rank where they do.
We take a different approach: the scoring rubric is published in full before it is applied, and the same rubric runs against every device in a category. When a Home Medix product, a Philips, an Oxymed, and a Yuwell are compared on a 5 LPM page, they are compared on the same axes with the same weights. If a score appears inconsistent with what the rubric says, the rubric is the authority and we will correct the score. When we borrow a loaner unit for bench testing, that loan is disclosed inside the review it informs. When we cannot verify a manufacturer claim, we say so and score only on the evidence we have.
Editorial team
Every review is produced by the HHZ Editorial Team and signed off by a clinical reviewer before publication. The team's standing roles:
- Medical reviewer — a practising pulmonologist or sleep physician who vets clinical claims, indications, and therapy-selection guidance against current peer-reviewed evidence and Indian professional-society positions.
- Biomedical engineer — responsible for the bench-test rig, sensor calibration, and measurement-uncertainty reporting. Signs off on all numeric claims we publish.
- Category editors — one per major category (concentrators, CPAP/BiPAP, nebulizers). Own the rubric, track model-year refreshes, and maintain the comparison matrix.
- Correction and fact-check desk — handles reader-submitted corrections and manufacturer rebuttals. Every correction is timestamped and the original wording is preserved in a visible changelog. See our correction policy.
Bylines and credentials appear on each individual review and clinical article. The editorial team can be reached through the contact points below.
