Temperature and relative humidity affect the scope of growth of viruses, bacteria, and fungi in the air. In order to prevent infectious diseases from spreading by aerosol or airborne infection, hospitals must maintain stringent environmental controls. Proper indoor air quality analyzer will help to maintain these parameters.
Most pathogens are exposed to the environment throughout their transit between hosts. Temperature, relative and absolute humidity, UV radiation exposure, and even atmospheric pollutants can all render free-floating pathogenic microorganisms inactive. The G150-11N Stowseek Air Quality Analyzer is one of the trusted equipment for checking the quality of the air condition.
In hospital settings, maintaining a specified temperature and relative humidity (% rh) is thought to reduce airborne survival and, as a result, influenza virus transmission.
Temperatures and relative humidity (rh) settings in different areas of a hospital vary slightly over the summer and winter. The suggested room temperature in the emergency room, including in-patient rooms, in the summer ranges from 23°C to 27°C.
Temperature has an impact on viral proteins and virus DNA, making it one of the most important factors in virus survival. When the temperature climbs from 20.5°C to 24°C, then to 30°C, virus survival decreases. This temperature-temperature relationship stayed true over a humidity range of 23 percent to 81 percent relative humidity.
What is the objective of relative humidity measurement?
Viruses and other infectious organisms rely on rh levels for their existence. At 21°C, influenza survival is at its lowest, with a mid-range of 40% –60% rh. The lifespan of airborne viruses in aerosols is constantly influenced by temperature and relative humidity (rh).
Bacteria: When the relative humidity (rh) was less than 25%, carbon monoxide (CO) enhanced the death rate of bacteria, but it protected bacteria when the rh was greater than 90%. Bacterial survival in the air appears to be reduced at temperatures exceeding 24°C.
Calibration should be done on a regular basis
Humidity and temperature measurement instruments are high-precision instruments that need to be repaired on a regular basis to stay in good working order. Despite the great long-term stability of our equipment and systems, we recommend that probes be calibrated on a regular basis — once a year is usually sufficient.
What else should you think about for healthy indoor air quality?
Dehumidification and HEPA filtration, as well as regular fresh air supply, can help to enhance indoor air quality. This is when CO2 is brought up as a secondary consideration. Its impact on interior air quality, particularly breathing air, is frequently overlooked. When the CO2 level (ppm: parts per million) exceeds 1000, it causes weariness and a loss of concentration.
Aerosols are notoriously difficult to quantify. As a result, when inhaling, the carbon dioxide released along with the particles is measured. As a result, a high CO2 concentration equates to a high aerosol concentration.
Finally, differential pressure measurement can be used to ensure that the proper positive or negative pressures are employed in rooms to prevent undesired items such as particles or bacteria from entering or exiting.
Fungus: Temperature and humidity-controlling ventilation systems have a significant impact on interior levels of airborne fungi, with air-handling units lowering concentrations while natural ventilation and fan-coil units raising them.
You will need high-precision measurements in hospitals that can work as indoor air quality analyzer. Look for a trusted source that offers a complete air quality range from single instruments to a full system for hospital measurement applications. The tried-and-tested solutions allow healthcare facilities to control and monitor their conditions while adhering to internal and external regulatory criteria.
