The healthcare industry also referred to as the medical industry offers various services such as medical services, manufacturing of medical equipment, drug discovery and development, medical insurance, educational institutions, clinical trials, hospitalizations outsourcing, telemedicine and medical tourism. The industry plays a role in disease diagnosis, its treatment and management. The industry also offers therapeutic, remedial and preventive services to the patients.
Healthcare industry is the largest sector in India in revenue generation and employment terms. In the 2021 budget, expenditure on healthcare by the public stood at 1.2% of GDP. India is expected to increase to US $ 133.44 billion by the year 2022. In the financial year 2021, 13.7% growth in health segments was recorded. Among total gross earned, the health segment shares 29.5% share in the country. In 2022, the healthcare industry is expected to grow $372 Billion at 39% of Compound Annual Growth Rate (CAGR). The Diagnostic market in India shares $4 billion.
The Indian healthcare sector is divided into two components private & public. The public system is government based comprising secondary and tertiary care institutions focusing on offering basic facilities of healthcare in key cities. However, the private system is common in metros and tier 2 & 3 cities.
AIR QUALITY PROBLEMS IN HEALTHCARE INDUSTRY
In a controlled environment, patients have rapid improvements than in an uncontrolled environment. Studies have shown, polluted indoor air aggravates 50 % of illnesses for which special attention and precautions are necessary for air quality. Main contaminants present in buildings are occupants, equipments, parking garages, kitchen, washrooms and furniture. Indoor contaminants can be categorized as chemical and biological contaminants. Examples of chemical contaminants are tobacco smoke, VOCs, Carbon dioxide, Nitrogen oxides and inorganic gases. Biological contaminants in hospitals are bacteria and viruses.
People are highly exposed to indoor air pollutants as they spend most of their time indoors. Particulate Matter (PM 10, PM 2.5 and PM 1), carbon monoxide (CO), carbon dioxide (CO2), total volatile organic compounds (tVOCs), formaldehyde (HCHO) and ozone (O3) are major indoor air pollutants.
Carbon Dioxide (CO2)
Exhaling air during human respiration is carbon dioxide which affects fresh air indoors. Higher CO2 levels show poor ventilation in the area. High levels affect the productivity and comfort of people present. Symptoms such as reduced productivity, headache, dizziness, restlessness, sleepiness, nausea etc are experienced by occupants.
Carbon Monoxide (CO)
A colorless gas released from cooking activities, blocked chimneys gas stoves, vehicular emission, burning of woods etc. CO when entered the human body interferes with oxygen-haemoglobin binding leaving the body oxygen deprived.
A colorless gas having a pungent smell releasing from paints, sprays, disinfectants, smoking, fuel burning appliances etc. Formaldehyde is carcinogenic and causes burning like sensations in nose, eyes and throat.
Particulate Matter (dust):
Mixing of soot, dirt and dust with atmospheric liquid droplets forms particulate matter. These are very small in size and cannot be seen with naked eyes. These can penetrate deep down the respiratory system upto alveoli distrupting the alveolar walls. It is released during renovations, cooking, constructions and cigarette smoking.
Ozone is one of the forms of oxygen where three oxygen atoms bind with each other. Nitrogen with volatile organic compounds forms ground ozone by photochemical reaction. Cigarettes, cooking, combustion etc causes ozone formation. Some printers and air purifiers also release ozone. Ozone when entered in the human body generates reactive oxygen species, causes asthma, airways inflammation etc.
Total Volatile Organic Compounds (tVOC)
Vinegar, nail paints, paints, deodorants, aerosol sprays etc release tVOCs indoors. It regulates odor. Inhalation of tVOCs lead to irritation in eyes, nose & throat, nausea, dizziness, lungs irritation, fatigue and skin problems.
Air Quality Solutions For Healthcare Industry
Air Quality Monitor
It helps you to know the quality of air present. Monitors are installed with special sensors that continuously monitor the concentration of parameters like particulate matter, carbon dioxide, HCHO, tVOCs. They are cost effective and easily portable. It monitors the key parameters in Real-time that are in sync with LEED, WELL and ASHRE and monitors parameters like PM10, PM2.5, PM1, CO2, TVOCs, HCHO, CO, temperature and humidity.
PCO Cell based Air Sanitizer
The sanitizer is based on Photocatalytic Oxidation technology which combines UV-C irradiation with a catalyst and removes the harmful biological contaminants such bacteria, virus, fungi & mold, and spores in a time span of less than 24 hours with efficiency rate of 99.99%. It is capable of killing SARS-COV-2 virus through molecular dissociation. Molecular dissociation kills the pathogen at its genomic level and is an irreversible change.
Fresh Air Machine
It filters pollutants in the indoor environment and gives clean air. It contains carbon layers and HEPA filters of 12-13 grade. It reduces regulation of bad air and increases fresh air regulation. It is easily installed in pre-constructed buildings. It turns on itself whenever the pollutants range exceed the adjusted levels. The Clean Air Delivery Rate (CADR) for formaldehyde is 200 m3/h and for PM is 200 m3/h. The coverage area is 24-41m2 with 99.05% filtration rate for PM 2.5, bacteria and virus. Fresh Air Machines are installed in premises that are not installed with traditional filtering methods.
