Letter to Hospitals and Doctors…read more Subject: Medical Practitioner Death and the Solution to Disinfect the Air Cond System of Hospitals The reports of medical frontlines increasing death is a question of why. They are well equipped with PPE and are the most qualified to know the dangers and strengths of the need for health safety such as wearing PPE, against the virus. The answer lies in that the most unanticipated source of contamination has not been eliminated altogether. This is the virus transmission caused by the air conditioning system in the hospital. Check the following: 1. Air condition operating principle. a. Air cond units have air discharge and exhaust that circulate air in a given closed room. b. When running, air condition temperature would be at least 24C, way below the virus limit to life temperature of 28C. Therefore air cond rooms are a good place for the virus to thrive. c. Each air-cond unit has an air filter which must be detached and cleaned to keep the room air quality sanitized. 2. Physical characteristics of the coronavirus. a. It can thrive in temperature up to 28before it dies down gradually. b. The distance the virus can travel is normally up to 1meter but can be longer depending on the strength of its discharge (sneezing or mouth droplets). c. The virus uses the moist of droplets and sneezes to survive. When this dries up the virus begins to deteriorate without its host moisture. Solutions to stop the virus circulation in the room. a. Clean the air cond units and disinfect the entire units at least once a month during this pandemic period. Use standard procedure of soap & water. And final air drying. b. Clean the air filter of the air cond separately from the unit. i. Take out the filter and avoid direct contact. ii. Wash thoroughly the filter with soap and water, meaning back to back. iii. Dry the filter at least 10 to 20 % moisture content if possible 100% dry. Do not wring but drip dry or air dry. iv. After drying the filter spray the filter with disinfectant end to end and back to back. v. Have a spare filter per air cond and change the filter every end of the day. The used filter can be again washed, dry, and disinfected as per above. If the filter is dischargeable, discharge to the trash can, use the procedure of hospital discharges. vi. When cleaning the air cond and filter the technician must wear PPE to ensure there is no contamination to himself. vii. Ditto, when daily pulling out the filter and replacing it with a new filter, both newly washed and disinfected filter or disposable filter. Also, medical workers must have separate dressing rooms to change and wear their PPE. No patient must be allowed inside such a room. a. The PPE dressing room must not have the personal effects and bags of the medical worker. Keep the room bare except for closet and shoe shelves and maybe benches. b. Disinfect the room every end of the day. If this goes unchecked the death will simply go on unknowing what is causing it. Other areas of the hospital must also be disinfected. c. The canteen must be disinfected wall to wall table to table. d. All cooking utensils, dishes, and cutlery must be disinfected after every use. e. All other rooms in the hospital must be similarly disinfected. Note: This procedure must also be used for malls, rooms, and halls where people assemble or gather for any purpose such as to dine, conference, seminar, shop, etc. Prepared by: Prof. Ernesto Abaya Guzman ME MM Ph.D. (cand) Loyola Height, Quezon City Philippines Email: guzaba2003@yahoo.com Cell: +63 9202167762 Note: 1.

When my 10 yr old daughter fell badly and broke her leg during our trip in Paris (a long and…read moresomewhat frightening story...especially for fellow parents), Necker children's hospital was a godsend. We knew it was a good place when Parisian acquaintances nodded and smiled when they heard the ambulance was taking her there. In retelling our tale to friends, we now affectionately refer to Necker as the "Lucile Packard of Paris" The staff was wonderful and supportive, and the care my daughter received was first rate. The amount of English spoken here, along with my wife's and my French, was enough to get us by quite well. We always felt they were putting our daughter's health and happiness first, which of course is the whole idea. My wife would also like to report that their fold-out futon couches are VERY comfortable. She stayed on one for a couple of nights. We had a few strange surprises (e.g. wheelchairs or crutches could not be obtained or rented from the hospital) but this was just French health care, not Hopitaux Necker. (Otherwise French health care worked just fine, thank you). Of course this incident put a damper on further Paris sightseeing until our flight home, but the important thing is my daughter is back home in CA (has been for weeks now), and she is happy, healthy and healing very quickly. We are feeling very fortunate indeed.
