Can One Scent Machine Cover the Reception and Open Rehabilitation Area of a Pain Centre?

It can, on four conditions, and it goes on the reception side; the conditions are the whole answer, so take them one at a time. First, the two rooms must be one volume of air. Stand at the desk and look toward the furthest treatment table. If there is no door that is closed between sessions, and the AC that serves the chairs also serves the mats, the reception and the rehab floor are one volume and one machine can address it. If there is a door that shuts, or the rehab floor has its own AC zone or sits on another level, they are two volumes, and a machine in one will not reach the other in any way you can plan; separate scented and fragrance-free zones is the rule that separate volumes get separate decisions, and the rehab volume's own decision is the large rehab area page. Second, the rehab floor must already smell of nothing. One machine over two rooms means the rehab floor receives a trace of the reception scent whether you want it to or not, and a trace over occupancy odour is a third smell. So before the machine is bought, the rehab floor passes a test - the middle of the floor at six on a full day, judged by someone who does not work there, and the answer is "nothing in particular". If it fails, the machine waits, and the spend is air changes, laundry and a wipe rota; the exercise-rehab zone page has that in four layers. Third, the whole connected volume must sit inside roughly 3,000 sq ft. A SOSA Vaayu is a waterless cold-air nebuliser rated to 1000m³, which the manufacturer describes as about 2,000-3,000 sq ft; most pain centres with an open rehab floor fall between 1,500 and 3,000 sq ft of patient-facing space and sit well inside it. Below 1,500 sq ft the Vaayu is not bought for reach at all - it is bought for its timer, its key-lock, its no-water design and the fact that it distributes through the AC rather than from a corner, and if none of those matter a reed at the desk is the honest answer. Above about 3,000 sq ft of connected air the step-up is one SOSA Angaan on the HVAC, rated to 3,000m³, and never a second Vaayu in the same air, because two sources in one volume do not make two levels, they make one higher level everywhere. Fourth, and the one that decides whether the plan works: the machine is placed on the reception side. An owner who wants one machine to "cover both rooms" instinctively puts it in the middle, or on the rehab side because the rehab floor is bigger. Both invert the gradient. The rehab floor should always receive less than reception - reception versus physio floor intensity is why - and one machine produces that only by being placed at the reception end, high on the wall the chairs face, away from the supply grille and the return, as far from the rehab opening as the room allows, so that the level is fullest where a patient sits still and has thinned to a trace by the time a moving patient meets it. If the return grille for the shared zone sits in reception, the machine goes to the opposite end of reception from that grille; a return beside the machine pulls its fullest air into the duct and delivers it to the rehab floor first. Where to place a scent machine in reception gives the four wrong positions, and even coverage in a large waiting area is why one high source beats several low ones. The setting is judged from the rehab floor at six and locked; reception gets what results, which is a trace at the door and nothing from the chair. The register is the building's - Mountain Breeze or Morning Freshness by the finishes, chosen in what a combined centre should smell like - and it is one register for both rooms, as the shared-signature page argues. What one machine never covers: procedure rooms, injection suites, fluoroscopy rooms and recovery bays, which stay unscented behind closed doors the machine is placed away from; and the consultation cabins, which are each doctor's call and inherit a trace or nothing. And 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. The whole building, volume by volume, is the family pillar, one fragrance strategy for a multidisciplinary centre.
