Indoor Air Quality is a key factor in hospitals, protection for people in the hospital environment must be comprehensive and include patients, healthcare staff and visitors
The risks that appear in a hospital are very diverse. Often we find strains resistant to routine treatments, such as nosocomial diseases, which can be a very serious problem in hospitals.
Almost 25% of the infections that occur in hospitals are of a respiratory origin; also 37% of all infections occur in intensive care units (EPINE, 2008). Suitable treatment of the air in these environments (ICU, infectious, boxes) is extremely important.
In addition to tempering the air, pressure control is required:
- Overpressure in cases of immunosuppressed patients.
- Under pressure in cases of infectious patients.
- Absolute filtration.
- Impulsion and adequate air extraction.
- Permanent monitoring of the atmosphere in these environments.
- Periodic validation of these environments according to the UNE 171340 standard.
The number of people with some type of immunosuppressed condition is increasing every day and the need to increase hospitals’ isolation capacity is increasing. Rooms for immunosuppressed isolated patients at positive pressure have considerable benefits in reducing the risk of catching diseases.
The demographic changes that have taken place in the last fifteen years in our country have highlighted the need to actively treat indoor air in hospitals. Furthermore, every day, infectious agents resistant to antibiotics appear in more hospitals, which already account for a very important part of all nosocomial infections.
In view of this situation, with emphasis on diseases such as tuberculosis, Ebola or tropical diseases, isolation rooms for infectious patients at Negative Pressure are required.
There are other isolated environments in hospitals that require the preparation and adaptation of air conditioning, ventilation, filtration, pressure control (positive or negative) and monitoring systems in the different types of laboratories:
- Pathological Anatomy.
- Biological research.
- Animal facilities.
From the control and monitoring technologies installed in the rooms, greater air flow control is achieved.
Isolation rooms, surgical blocks and hospital laboratories require high-performance ventilation systems that ensure safe, stable and reliable working conditions. For this reason, they require supervision, monitoring and control systems that allow visualisation, control and clear and precise warning of medical staff.
The integration of innovative solutions into critical rooms enables an increase in energy efficiency.
