One Scent Machine or Multiple Zones for a Large Pain Clinic?

You decide by counting volumes of air, and you do the counting with a pen on the floor plan before you look at a single product. A machine scents the air it can reach, and air stops at two things: a door that stays shut and a change of air-conditioning system. It does not stop at an open doorway, an archway, a corridor or the edge of a room on the plan. So the first step is to draw a line on the plan wherever a door between two patient-facing areas is shut in normal use - and a second line wherever the AC changes from one unit or zone to another with its own supply and return. Every enclosed patient-facing area that results is one zone, and the number of zones is your machine count. In most large pain clinics that count is one: reception, waiting and the corridor to the cabins share one air, and the rehab floor, if there is one, opens off that corridor without a door that stays shut. One SOSA Vaayu at ₹11,999 - waterless, 1000m³, timer, key-lock - mounted high at the hospitality end of that zone, on the wall the reception chairs face, away from the entrance draught and the AC return and as far from the procedure suite as the wall allows, holds the whole zone at a level that falls from the desk to the far end, which is the direction it must fall. In some clinics the count is two: a rehab gym upstairs behind a stair door, a second waiting area for a separate department on its own AC. Each zone then gets its own decision, and the decision is not automatically a machine. A second zone that is a first-floor waiting nook of 200 sq ft gets a Mountain Breeze reed at its desk, because a Vaayu's minimum would fill it; a second zone that is one open room of 300-750 sq ft gets a Sukoon or a Vaayu by the same reasons that decide it at 750 sq ft and 1,000 sq ft; a second zone that is a rehab floor gets a machine only once it smells of nothing on its own at six in the evening, and scenting a pain clinic with a large rehab area refuses it until then. Then the zones that are drawn in a different colour and get nothing whatever the count: the procedure rooms, injection suite, C-arm room, recovery bay and curtained treatment cubicles are clinical zones and take no machine - not a small one, not a low one, none - and the way to keep the patient-facing zone's fragrance out of them is placement at the far end, doors kept shut between cases and, where the AC allows, a return grille that does not pull reception air through the suite. Which areas of a pain clinic should be kept fragrance-free is the full list and separate scented and fragrance-free zones in a large centre is this method from the clinical side. The consultation cabins are their own small zones with doors, and each is the doctor's call, nothing inside by house recommendation. When you are not sure whether two areas connect, there is a test that costs nothing: run one machine in the first area for a week and stand in the second at four in the afternoon. A trace means the air is connected and it is one zone - a second machine there would double up where the two overlap, usually at the desk, and produce a nameable level exactly where the slowest patient stands longest. Nothing means the boundary is real and the second area has its own decision. And the rule that never bends: never two Vaayus in one zone. An uneven zone is fixed by placing the one machine better, and a zone genuinely too large for one Vaayu - past about 3,000 sq ft of one continuous air - takes one SOSA Angaan at ₹25,999 on the air handler, which the 2,000+ sq ft centre sets out. The standing sentence: fragrance is an ambience decision like lighting or seating. It does not reduce pain, anxiety or stress, it does not affect outcomes, and the clinician's judgement overrides any plan, including this one. Whether a clinic needs a machine at all before it counts zones is the family pillar, when does a pain management centre need a Vaayu.
