VentPlus for healthcare

The waiting room
is the crowded room

An OPD waiting area, a diagnostic centre reception, a dialysis floor, an IVF lab — these are rooms where people sit shoulder to shoulder for hours, often in a building where the ventilation was designed for a much smaller crowd. CO2 is the fastest, cheapest, most continuous way to know whether that ventilation is actually working right now.

VentPlus measures CO2, temperature and humidity continuously, switches ventilation on when the room needs it, and logs every reading to a dashboard you can download to Excel. It is a control device and a record at the same time.

420ppm Excellent Outdoor air, before the doors open.
800ppm Good Well-ventilated occupied space. The target.
1,000ppm Moderate Ventilation is no longer keeping up with the crowd.
1,500ppm Poor A clear signal of insufficient outdoor air for the occupancy.
2,500ppm Very Poor Routine in packed waiting halls with sealed windows.
4,000ppm Severe Fatigue and headache in staff working a full shift in it.
A proxy, not a pathogen sensor

CO2 does not measure infection risk directly, and VentPlus is not a medical device. What CO2 does measure is how much of the air in the room has already been through someone else's lungs — which is why public-health guidance during and after COVID-19 settled on CO2 monitoring as the practical way to check that shared indoor spaces are being ventilated.

The VentPlus solution

Continuous measurement, automatic response,
and a record you can show someone

Manual spot-checks with a handheld meter tell you about one minute of one day. VentPlus reads the room continuously, acts on what it reads by driving the exhaust or fresh-air fan, and keeps the history. When an accreditation body, an infection-control committee or a hospital board asks how the ventilation in a given area performs, the answer is a chart rather than an opinion.

1

Measure where the people are

Waiting halls, OPD corridors, reception, day-care rooms, staff rooms, canteens — the crowded non-clinical spaces where CO₂ climbs highest and monitoring is usually thinnest.

2

Act automatically

The relay drives the existing exhaust or fresh-air fan the moment your threshold is crossed. A 3-position Auto/Off/On switch gives staff a manual override when they need one.

3

Keep the record

Every reading uploads over Wi-Fi. Historic CO₂, temperature and humidity export to Excel for audits, reports and infection-control review.

Real-Time and Historical CO2, Temperature
and Humidity Monitoring From Anywhere

A facilities engineer can watch every monitored area from one browser — which floors go stale in the afternoon, whether the new AHU setting actually changed anything, whether the fan on the second floor is running at all. The record is continuous, so a problem shows up as a trend rather than as a complaint. CO2, temperature and relative humidity each have their own graph over the same window, and the Excel download gives all three, reading by reading, for audits and infection-control review.

What CO₂ tells you in a healthcare building

Hospitals already ventilate their critical areas to standard. The gap is almost always in the ordinary rooms — waiting areas, corridors, staff rooms — where occupancy is high, design assumptions are old, and nobody is measuring.

62.1
The ventilation standard

ASHRAE Standard 62.1 sets minimum outdoor-air rates per person and per unit floor area. CO2 concentration is the practical, continuous check on whether a room is actually receiving them, and it is what demand-controlled ventilation systems act on.

ASHRAE Standard 62.1
±50ppm
Sensor accuracy

An industrial NDIR sensor, accurate to ±(50 ppm + 5% of reading) after a 10-minute warm-up, measuring across 400–5,000 ppm. NDIR measures carbon dioxide directly and stays stable for years, unlike the cheap chemical sensors used in consumer gadgets.

Common questions

CO₂ in healthcare buildings — questions we get

No, and we will not describe it as one. VentPlus is an industrial CO2 monitor and ventilation controller. It measures carbon dioxide, temperature and humidity, and switches a fan. It does not measure pathogens, particulates or anaesthetic gases, and it is not certified for use in operating theatres, ICUs or other critical clinical areas governed by ASHRAE 170 or NABH clean-air requirements. It is used in the ordinary crowded rooms of a healthcare building.
Because CO2 is the one indoor pollutant that comes almost entirely from the people in the room, which makes it a direct read-out of how much of the air has already been breathed. That makes it the standard proxy for ventilation adequacy — a room at 700 ppm is getting plenty of outdoor air; a room at 2,200 ppm is not, whatever the AC is doing.
Below 1,000 ppm, and many hospitals set the fan to trigger at 1,200 ppm and stop at 800 ppm to keep a comfortable margin. Well-ventilated occupied space sits at 600–800 ppm; outdoor air is around 420–450 ppm.
Yes. Every unit uploads CO2, temperature, humidity and relay status over Wi-Fi to the VentPlus monitoring website, and the historic series downloads to Excel. That gives an infection-control or accreditation review an actual time series instead of a one-off handheld reading.
No, and that is the point. VentPlus plugs into a 230V socket; the fan plugs into the unit's AC socket (3A / 700W). There is no commissioning project. Larger fans and AHU dampers are driven through a contactor or via the Wi-Fi Relay Unit.
One Main Unit covers about 100 sq m with moderate air circulation. Most hospitals start with the three or four areas they already suspect — the main OPD hall, a busy waiting area, a staff room — and expand once the dashboard shows them which rooms are genuinely worst.
