Indoor Air Quality is a key factor in hospitals and personal protection in hospital environments must be comprehensive and include patients, healthcare staff and visitors.
Hospitals are prone to a wide variety of risks. We often find strains that are resistant to routine treatments, such as nosocomial diseases, which can be a very serious problem in hospitals.
Almost 25% of the infections caught in hospitals are of a respiratory origin and 37% of all infections are picked up in intensive care units (EPINE, 2008). It is extremely important to ensure that the air in these environments (ICU, rooms for infectious patients, boxes) is treated properly.
In addition to tempering the air, pressure control is required:
- Overpressure in cases of immunosuppressed patients.
- Lower pressure in cases of infectious patients.
- Absolute filtration.
- Impulsion and suitable air extraction.
- Continuous monitoring of the atmosphere in these environments.
- Periodic validation of these environments according to the UNE 171340 standard.
The number of people with some form of immunosuppressed condition is rising every day and as a result, there is a growing need to increase the isolation capacity of hospitals. Isolation rooms for immunosuppressed patients at positive pressure help to considerably reduce the risk of catching diseases.
The demographic changes that have taken place over the last fifteen years in Spain have highlighted the need to actively treat indoor air in hospitals. Infectious agents which are resistant to antibiotics are also seen in more and more hospitals every day, and these already account for a very high percentage of all nosocomial infections.
This situation, with emphasis on diseases such as tuberculosis, ebola and tropical diseases, brings to light the need for isolation rooms for infectious patients at Negative Pressure.
There are other isolation 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.
Greater air flow control is achieved thanks to the control and monitoring technologies installed in the rooms.
Isolation rooms, surgical suites and hospital laboratories require high-performance ventilation systems that ensure safe, stable and reliable working conditions. They therefore need supervision, monitoring and control systems that are able to be clearly and accurately viewed and controlled by medical staff, as well as being able to send staff warnings.
With the introduction of innovative solutions, critical rooms become more energy efficient.
