ResMed Lumis 100 VPAP ST price in India: who actually needs a BiPAP ST
Last updated: 2026-10-28
Quick answer
The Lumis 100 VPAP ST is ₹47,750 and is a bilevel machine, not a CPAP. It delivers two pressures — a higher one as you breathe in, a lower one as you breathe out — and in ST mode it will deliver a breath on its own if you do not take one in time. That backup rate is the whole point, and it is why the machine is prescribed for hypoventilation, COPD overlap and neuromuscular disease rather than for ordinary obstructive sleep apnea. If your report says plain OSA, the ₹51,000 AirSense 10 AutoSet is the right machine and the cheaper one.
What "VPAP ST" actually means
VPAP is ResMed's name for bilevel therapy — what most people call BiPAP. Instead of one steady pressure, the machine gives you a higher inspiratory pressure (IPAP) and a lower expiratory pressure (EPAP). Breathing out against a lower pressure is far easier, which is why bilevel suits people who cannot tolerate a high fixed CPAP pressure.
The ST stands for spontaneous/timed. In S mode the machine follows your own breathing. In ST mode it also watches the clock: if you do not start a breath within a set interval, it delivers one. That backup rate is what makes the machine a treatment for people who do not reliably breathe enough on their own, and not just a comfort upgrade.
Who the Lumis 100 ST is for
Typically: obesity hypoventilation syndrome, where CO2 builds up overnight; COPD with sleep apnea (overlap syndrome); restrictive chest wall disease; and neuromuscular conditions such as muscular dystrophy or motor neurone disease, where respiratory muscles weaken. In these cases the prescription usually names IPAP, EPAP, a backup rate and sometimes a timed inspiration, and it comes from a pulmonologist rather than from an auto-titration.
Also: a smaller group of people with severe obstructive apnea who need pressures so high that CPAP becomes intolerable, or who have significant central events alongside the obstructive ones. See signs you might need a BiPAP instead of a CPAP and BiPAP for COPD and respiratory patients.
When you should not buy it
If your sleep study reports obstructive sleep apnea with a high AHI and no mention of hypoventilation, retained CO2 or central apneas, a bilevel ST machine is overtreatment and ₹47,750 is the wrong place to spend. The AirSense 10 AutoSet at ₹51,000 auto-adjusts between a pressure range and handles the large majority of OSA, including severe cases.
A bilevel machine set by guesswork is also actively unhelpful. Pressure support that is too wide can worsen central events; a backup rate set wrong can fight your own breathing. We will not configure one without a prescription that names the settings. CPAP vs BiPAP explains the distinction in plainer terms.
What you get for ₹47,750
A genuine ResMed Lumis 100 VPAP ST with the integrated HumidAir heated humidifier, CPAP, S, ST and other modes, climate control for the tube, and a 2-year warranty. Delivery anywhere in Kerala in 2–4 days, settings entered from your prescription, and the mask fitted — masks are quoted separately because a bilevel user at higher pressures often needs a full-face mask rather than a nasal one.
Compared with other bilevel machines on the Indian market, the Lumis line is the one most Kerala pulmonologists recognise and write for, which matters when your doctor wants to change a setting over a phone call.
Rent it before you buy it
Bilevel therapy is harder to get right than CPAP, and the settings often change in the first month or two. Renting a BiPAP ST at ₹3,500 a month lets your doctor adjust while someone else owns the machine. Many of our bilevel customers rent for two or three months, settle on the numbers, then buy the Lumis and keep the same settings.
If you are not yet diagnosed, or your report is older than a year, start with a home sleep study for ₹2,500 — a bilevel prescription should rest on current data. Our CPAP machine price guide covers how bilevel pricing compares with CPAP across India.
