Air quality and preventing infection

How is the risk of airway contamination minimized in hospitals and at home?

On average, people in the UK and much of Europe spend around 90% of their time indoors – and few know that the air they breathe in their homes, workplaces, shops and other interiors can be up to five times more polluted than that Air outdoors. Indoor air pollution can include dust, mites, dander, mold spores, volatile organic compounds (VOC) and pathogens: common infectious agents that are of particular concern in clinical and hospital environments, including Staphylococcus, Streptococcus and Enterococcus species; Variants of pneumonia; and – as a relatively new but significantly more virulent example – COVID-19.

Air quality and infection prevention

Clinically significant microorganisms can be introduced
Health attitudes through a number of external sources, including people, water,
Building materials and air currents. The introduction and dissemination of
Bacteria, viruses and fungi in the air in hospitals can be attributed to this
poorly maintained heating, ventilation or air conditioning systems; to open
Windows and doors; Ceiling insulation and false ceiling spaces; and air
Filters, among other vehicles.

Risk patient populations

Certain patient data are particularly susceptible to infections in the air, either due to a weakened immune system – such as in the elderly, patients undergoing chemotherapy, or in patients with HIV – or due to risks associated with the profession, lifestyle of a patient or restricted access to medication are related to care. Risk groups in this second population group can include drug users, members of medically underserved communities such as the homeless or patients with a migrant background. and health and care workers who are more likely than most to come into contact with infected people, surfaces, or air over longer periods of time.

Optimizing air quality to minimize risk

The transmission of harmful microorganisms into the air can be
arrested and defused in various ways. One of the most important options
Stopping the spread of infection from contaminated air is the implementation of
common, comprehensive, and consistent cleaning and disinfection protocols for everyone
Air conditioning, filter and ventilation systems that a
significant risk factor for the transmission of diseases indoors.

The United States Centers for Disease Control and Prevention (CDC)
draws particular attention to the risks to air quality in hospitals
Construction and renovation work that can cause dirty or disruptive or disruptive substances
contaminated materials; Cause or worsen water leaks that contribute to a
hospitable environment for mushrooms; and impair the free air flow
Fans or ventilation systems. The CDC therefore recommends increased caution if
Planning the construction in hospital environments with the following words: "Construction,
Renovation, repair and demolition work in health facilities require
extensive planning and coordination to minimize the risk to the air
Infection both during the projects and after their completion.

“Environmental services, employee health, engineering and
The infection control must be represented in the construction planning and planning
Meetings should be convened with architects and designers. "

The room air should be taken, monitored and analyzed regularly
for signs of contamination and disease transmission.

Monitoring and cleaning the indoor air

Air purifiers have come a long way since their introduction.
and modern air purification technology is more than sufficient today when it comes to that
Providing optimal indoor air quality. There are a variety of air purifier types
available; Perhaps the best known of the group is HEPA (High Efficiency)
Particle filter) filter. Developed during World War II to remove radioactive substances
Toxins that result from the creation of atomic bombs, the HEPA is still the most
Efficient air filter type available. They are made of fiberglass and
Specializing in the removal of dust, mites, pollen, mold, dander, bacteria and
99.97% of the most common allergens.

Activated carbon filters (AC) use adsorption technology. Not
to be confused with absorption, adsorption refers to the attachment of atoms,
Ions or molecules (from gas, liquid or dissolved solids) to a specific one
Surface. AC filters specialize in trapping chemical vapors, odors, gases and
Smoke. Ionizers and ozone generators are also examples of modern air
Cleaning technology. Although they don't boast the same impressive rate of
Efficiency like the HEPA or AC filters work proactively; Meaning different
HEPA and AC, they don't rely on fans to work.

Home automation technology for cleaner air

Smart technology is becoming more affordable. Use an integrated HVAC system and an entire house cleaning network. One of the latest technological developments, home automation, can now be used to track and improve indoor air quality. With an automated indoor air quality monitor, users can view real-time data on their phone, as well as past measurements and events.

When the system receives a report of poor air quality from the
Monitor, it can trigger the activation of fans, adjust humidity and boost
Airflow that returns clean air through all air vents in the air conditioner
At home. In addition to air cleaning, an intelligent thermostat and air cleaning
System reduces the amount of energy that a house uses and ultimately saves that
Homeowners money.
