HEALTHY CLIMATE AT THE HOSPITAL

To make hospitals a safe place for patients, visitors and professionals, it is important to take all available measures to minimise the risk of infection. But how can we create an environment that is as safe as possible, where disease transmission is almost impossible? The answer lies, among other things, in the air and thus in the ventilation system.

Indoors, good air quality has been shown to not only increase well-being, but also actively contribute to faster recovery, health and workplace productivity.

In a hospital with a wide variety of areas, a wide variety of requirements must be taken into account:

  • Air cleanliness and Hygiene
  • Comfort level and occupational health and safety
  • Safety and fire protection
  • Aspects of operation and costs

CRITICAL AREAS IN THE HOSPITAL

In hospitals, treatment, laboratory and operation areas place the highest demands on hygiene and indoor air standards. This applies not only to the purity or particle-free nature of the air: the entire air management system must operate at the best level. Targeted control of the room pressures in negative or positive pressure separates the various areas from each other or from their surroundings in terms of air distribution technology. By continuously monitoring the parameters, you always have an overview of the current conditions of your rooms.

TROX clean room technology continuously meets the highest protection and safety standards and is therefore found in many highly sensitive areas such as: We are aware of the need for comprehensive solutions, as well as the interaction of diverse factors relevant to purity and safety. Therefore, we always develop our concepts and systems under consideration of the following:

AIR TREATMENT, TRANSPORT, FILTRATION AND SUPPLY:

High air cleanliness and comfortable indoor air quality

AIR MANAGEMENT:

Protection of products, processes, people and the environment from contaminated air

FIRE PROTECTION:

Preventing the spread of contaminated air, fire and smoke, as well as the safeguarding of smoke-free rescue routes, through ducting in the event of a fire

EFFICIENCY:

Attention to energy and cost efficiency in the area of air conditioning and ventilation

YOUR ROOMS - OUR SOLUTIONS

OPERATING THEATRE WING

The top priority in operating rooms is the prevention of post-operative infections (POI). Indoor air technology provides significant assistance in this regard.

Due to the necessary low level of germs, an operating theatre unit is to be classified as room class 1a or 1b according to DIN 1946-4. Contamination of the indoor air by bacteria, viruses and spores must be reduced to a minimum. The removal of anaesthetic vapours, dust and odorous substances also plays an important role here.

A wide variety of aspects are therefore central to the indoor air technology in the operating theatre wing:

  • Compliance with the positive air balance (positive pressure) to prevent the penetration of possible contamination from adjacent rooms

  • Maximum relative room humidity below 50 % r.h.

  • Fresh air flow rate between 800 - 1200 m³/h to limit the danger posed by anaesthetic gases

  • Freely selectable temperatures between 18 and 24°C (possibly up to 27°C in paediatric surgery)


In order to guarantee these points, indoor air conditioning systems must offer at least 2 filter stages that constantly draw in, humidify and dehumidify, filter and temper the indoor air according to the requirements

Standard in the classic operating theatre are tissue ceilings that ensure a so-called low-turbulence displacement flow (TAV). In terms of air technology, operating theatre units are similar to Clean rooms.

Let our industry experts advise you on your individual options.



►Everything you need to know about air technology in clean rooms►►

ICU/ISOLATION WARD

When highly infectious patients need to be cared for or persons with severe immunosuppression need to be protected, nursing rooms and intensive care units also belong to the room category of critical areas. 

As a result, the requirements for infection control and hygiene are also increasing. The ventilation and air-conditioning system contributes to the protection of patients and staff by cleaning the room and supply air.

What is important in critical ICU patient care rooms includes, among other things:

  • Mechanical ventilation with particle-filtered supply air and/or extract air
     
  • The use of passive or active airlocks
     
  • Static pressure maintenance in positive or negative pressure (aseptic/septic)
     

If these important factors have been taken into consideration, the staff is optimally protected from the point of view of ventilation and air conditioning and there are good conditions for an ideal recovery process for the patients. 

We will be happy to advise you on designing, equipping or modernising your premises with our innovative and flexible solutions.

LABS

Everyday laboratory work involves working with substances that are hazardous to health or dangerous in order to produce or research new medicines. 

This requires special measures to protect employees, the environment and products. In addition, a comfortable working environment with high indoor air quality and a pleasant climate must be created. 

Here, the ventilation system plays a decisive role by regulating both the supply air and the removal of contaminants.

To achieve the legal protection goals, the following factors must be taken into consideration in the air management system:

  • Balancing the volume flow rates of room supply and extract air, as well as technical extract air
     
  • Dissipation of thermal loads
     
  • Regulation of the required room pressures
     
  • Reduction of airborne particles, if applicable
     

If all these aspects are fulfilled under the relevant requirements, the protection of employees is also guaranteed.

With bespoke solutions, TROX develops new systems in all areas related to research facilities and laboratories. Profit from our extensive know-how. 



► Ventilation solutions for your laboratory ►►

CENTRAL STERILISATION

Special care and hygiene are required within the sterilisation processes. Proper cleaning of surgical instruments has a direct influence on the postoperative infection rate and therefore contributes to the patient's rapid recovery in the ideal case. 

In this area, ventilation and air-conditioning systems must meet the highest requirements to protect people and technology. Unlike in unclean areas, there must be a positive pressure here. 

The following points are decisive for the control of the external volume flow:

  • Thermal loads
     
  • Humidity
     
  • Hazardous substance exposure
     
  • No. of people
     

Our flexible and bespoke solutions are used wherever the highest demands are placed on air hygiene and indoor air conditions:

SENSITIVE AREAS IN HOSPITALS

There are many sensitive sections inside medical buildings. According to DIN 1946 Part 4, they belong to room class II and include all non-public areas, such as

  • Patient rooms
  • Treatment rooms
  • Rooms in the normal care 
  • Examination and recovery rooms
  • MRI and CT rooms
  • Corridors
  • Storage rooms 


Hygiene and safety aspects are strictly regulated here to protect patients and staff. Various requirements are also placed on the indoor air. In contrast to critical areas, temperature and humidity control and the reduction of potentially infectious aerosols are of primary importance in sensitive areas. The latter has become particularly relevant in the wake of the COVID-19 pandemic.

As a pioneer in the industry, TROX has dedicated itself intensively to the filtering possibilities of aerosol contents. We offer customised and safe indoor air concepts for all sensitive areas of healthcare.

ER

The central emergency room (ER) is a primary point of contact for patients in need of acute care. Lives are saved here every day.

While the number of cases has risen steadily in recent years (source: Ärzteblatt), many people have concerns about visiting an ER because of Sars-Cov-19. The reason: patients who stay there are often already ill –  and thus may carry potentially dangerous germs and viruses. Their breathing alone produces aerosols that transport the corresponding pathogens into the ambient air and can lead to the infection of other people. This is precisely where a correspondingly great challenge lies for air management. 

In addition, the indoor climate in this area of the hospital is characterised by interior rooms, numerous medical devices with high heat loads and often an insufficient air supply from outside. In the warmer months, the room climate in the ER is also under particular strain due to a large number of patients. In winter, on the other hand, draughts and unwanted cold must be prevented indoors.

The following is therefore vital for a pleasant room atmosphere: 

  • A sufficient supply of outdoor air 

  • Temperature and humidity control 

  • Maintenance of air quality through filtration and airflow
     
  • Airlocks in the passageway for the patients arriving in the prone position 

If these criteria are met, the indoor climate in this usually hectic zone of the hospital contributes positively to the recovery of the patients, as well as creating a pleasant working atmosphere.

PATIENT ROOMS, NURSING WARD AND RECOVERY ROOMS

In rooms where patients spend longer periods of time, high air quality is not only pleasant, but also beneficial to health. Bad odours and stagnant or stale air are noticeable and make visitors and staff uncomfortable.

In this context, precisely coordinated ventilation and air conditioning can even contribute to a faster recovery and thus accelerated discharge of patients from hospital.

Furthermore, clean air has a positive effect on the working atmosphere of healthcare professionals and thus brings a potential increase in productivity. Considering these two factors, a well thought-out indoor air concept contributes greatly to efficient hospital operations. For this reason, individually suitable indoor air solutions are particularly important in sensitive areas such as patient rooms, examination rooms, nursing wards and recovery rooms.

The tasks of a corresponding system essentially consist of the following points:

  • Turbulence-free air exchange

  • Humidity control

  • Fresh air volume flow rate according to the specific room use

  • Room temperature between 22°C and 26°C


With suitable elements such as HEPA filters, the risk of infections caused by aerosols is also minimised.

Let our industry experts advise you on the most efficient ways to help your patients breathe easier.

STORAGE ROOMS

Storage rooms, such as those used to stock medicines, are by no means exclusive to hospitals, but can also be found in pharmacies, doctors' surgeries and nursing homes.

Most preparations can be stored at room temperature between 15°C and 25°C without risking loss of efficacy. However, there are also substances that require refrigeration, such as insulin, vaccines or certain eye drops, which require permanently cool storage (between 2°C and 8°C)

Moreover, it is not only medicines that require appropriately safe and air-conditioned areas for storage. With regard to rising temperatures in summer and condensation, for example, the topic of indoor air takes on an important role with regard to textiles, among other things. 

In addition, occupational health safety aspects must be observed, especially in disinfectant and solvent storage facilities. 

The following points are of central importance for the indoor air, depending on the stored items:

  • Constant room

  • Humidity control

  • Protection against light

With TROX, you can store your medicines and other important products optimally and safely, even when outside temperatures fluctuate.

PUBLIC AREAS IN THE HOSPITAL

Clean air is not only of high importance in treatment and operating rooms. Especially in rooms with a lot of public traffic – such as waiting rooms, reception areas and administrative offices – clean air should be a matter of course. In addition, the coronavirus pandemic has established a heightened sensitivity to the possible transmission of pathogens through the air. 

In public areas of the healthcare sector, people come together who are often already ill. Regular spray and wipe disinfection is not enough to prevent infection because, in many viral diseases, such as gastrointestinal infections or SARS-CoV-2, the pathogens literally fly through the air.

COMPLETE INDOOR AIR CONCEPTS

So what options are there for filtering out these pathogens, but also pollen and fine dust, for example, effectively and yet cost-efficiently, without reducing the comfort of the room through disturbing noise or draughts?

Rely on our comprehensive indoor air concepts and innovative products with which we constantly set new standards in hygiene and safety. We will be happy to advise you extensively and present the most effective solution options for your individual premises and areas.

YOUR ROOMS – OUR SOLUTIONS

RECEPTION AND LOUNGE AREA

"Please take a seat in our waiting room" is often heard in medical facilities. To protect the patients, various disinfection facilities are placed within corresponding zones. However, they cannot replace an air washer with a special HEPA filter. This removes harmful germs and viruses directly from the air that surrounds you.

It is possible to install a ceiling filter or to use a floor unit in smaller rooms. Here, observing not only the hygiene standards, but also the comfort requirements of patients and staff, is vital. Central aspects for your reception area include:

  • Filtration of fine dust, house dust, allergens and other contaminants
     
  • Reduction of the aerosol concentration
     
  • Temperature control
     
  • Prevention of draughts
     
  • Protection of privacy and therefore no room air change via door undercuts (DIN 4109)
     
  • Pressure-neutral ventilation operation for compliance with the sound insulation standard
     


ADMINISTRATION AND OFFICES

Medical building complexes include not only treatment, care and waiting areas, but also offices and administrative wings. 

For the employees working there, the best possible indoor air quality is essential. The high demand for office air exists not only in terms of the increased likelihood of infection in hospitals, but also in terms of productivity and satisfaction. Simple Plexiglas walls or occasional ventilation are not sufficient within the scope of a comprehensive hygiene concept to achieve the necessary standards.

The ventilation and air conditioning strategy for offices depends on many factors. 

  • Architecture and building type
     
  • Location
     
  • Room volumes and layout
     
  • Occupancy and building type must be taken into consideration. 
     

Our know-how and the wide range of ventilation and air-conditioning systems, devices and components enable us to respond to your individual requirements.


PHARMACIES AND SALES AREAS

Professional advice in a hospital is not only provided by competent doctors and nurses. Many facilities have their own pharmacy where necessary medication can be obtained directly on site.

A pleasant atmosphere with clean and well-tempered air contributes to customer satisfaction and staff productivity in addition to the comfort aspect.

In light of this, ventilation and air conditioning systems have to adapt to constantly changing environmental conditions while continuing to run efficiently.

Within the hygiene management for your pharmacy, consider the effectiveness of air filters and offer your visitors a safe and pleasant shopping experience.


KITCHEN AND CAFETERIA

The health of patients is the absolute focus in medical facilities. In addition to accurate medical treatment, physical well-being is also important. 
 

In the kitchen and cafeteria, however, not only tasty dishes are created, but also odours that must be effectively kept away from the rest of the building. 

Working within an area where food such as hot fats is handled also requires a high level of hygiene and safety. 

Not to be forgotten are also the high thermal loads that have to be dissipated as efficiently as possible.

HIGH HYGIENE STANDARDS AT THE HOSPITAL

Air is life, because it provides us with necessary oxygen. But what if the immune system has been compromised? In such a case, air can even become life-threatening. Pollutants, bacteria, or even a virus may be introduced with each breath taken. A healthy body can usually cope with such microorganisms without any problems, but a sick body cannot.

For this reason, the conditioning and control of airflows in hospitals are of almost elementary importance, because medical facilities are confronted with new challenges such as multi-resistant viruses, germs and pathogens every day. "Every year, 400,000 - 600,000 patients in Germany fall ill with hospital-acquired infections, some of which can be prevented or influenced," – says a report by Germany's Federal Ministry of Health (DE only).

Go one step further in hygiene and safety together with us. The new features of our systems are specially designed to meet the high requirements for air hygiene and air purification in highly sensitive areas.

AIR DISTRIBUTION TECHNOLOGY

Ventilation and air conditioning systems in hospitals ensure that the contamination of indoor air with micro-organisms is reduced to a minimum. Moreover, dust, anaesthetic gases and odorous substances must be contained.

This applies in particular to operating theatres, intensive care units, delivery rooms and neonatal units. The risk of infection is minimised by the correct air distribution and effective air filters. But that is not enough: Air can easily overcome barriers and can, hence, not be locked out.

Using precise pressure control and airlocks, however, it is possible to isolate rooms with particularly critical requirements on air cleanliness.

HOSPITAL - SAFETY IN THE EVENT OF FIRE

In regard to fire protection, hospitals and nursing homes are particularly critical, as the fast evacuation of patients places high demands.

According to statistics from the Association of German Fire Protection Officers, there is a fire in a hospital in Germany every 18 days and even every eight days in a retirement and nursing home.

Fire protection in hospitals and nursing homes is not only a special challenge from a technical point of view: In the event of an incident, people who cannot save themselves under their own power often have to be helped. A fast evacuation is essential.

FAST EVACUATION – THE TRUE DANGER IS THE SMOKE

Rescuing people and patients is the top priority in the event of a fire alarm. If a fire breaks out, every minute counts. The focus is on those who cannot get to safety in time under their own steam. While those needing help do not necessarily consist of senior citizens in hospitals, old age is the rule in nursing homes.

In case of fire, a high smoke concentration is produced very quickly. This is dangerous for two reasons: 

  • For one thing, the smoke quickly takes away your vision and you can become disoriented.

  • On the other hand, the smoke is very toxic and a few percents by volume is enough to render one unconscious.


It is therefore crucial how quickly the dangerous smoke can be evacuated so that both staff and rescue workers have enough time to safely evacuate everyone present from a hospital or nursing home.

WE ARE EXPERTS IN FIRE PROTECTION AND SMOKE EXTRACT

The safety of patients, nursing home residents and employees can only be ensured with a coordinated overall fire protection concept that includes all structural, system engineering and operational-organisational components. 

The overall concept determines the effectiveness in the event of a fire in order to minimise the risk of fire and to extend the intervention time in the event of an emergency.

The expertise of TROX in the field of fire and smoke protection is unique. For decades, TROX has been developing components and systems for fire and smoke protection in buildings and underground transport systems. 

We are available to you as a competent advisor for all questions concerning the topic of smoke protection and extract in your project from the beginning. Together with you, we develop a customised concept to help you achieve your project goals.
