Vital compressed air supply cannot pause for breath

Saving and protecting patients' lives ranks first in hospitals. In this respect, a continuous supply of compressed air for medical use is of key importance.

Whether for normal care, intensive care, in theemergency ward or the operating room: in all thedepartments of your hospital patients depend onartificial ventilation. In order that the patientalways gets medical compressed air in the pro-per quality, in the right volume, and with the rightpressure, you will require a central compressedair system that satisfies the specific needs of amodern hospital.

To achieve this, it is essential that international regu-lations as well as normative directives are observedand that the quality of the medical compressed airmeets the defined guidelines.The operational safety of the installation and, conse-quently, the health and well-being of your patientsdepend on the fulfilment of all these requirements.We will help you to fulfil this great responsibility.From planning, to construction and certification ofyour central compressed air installation, all the wayup to the ongoing operation, we stand by your sideas a reliable partner.

Efficiency through tailor-made designAn efficient and energy-saving compressed air sys-tem contributes to the economic efficiency of yourhospital. Since the system runs around the clock, ahigh degree of efficiency leads to substantialsavings for the entire operation. Thanks to our sys-tems know-how, we are in a position to optimise thealignment of both the individual components of thecompressed air system, such as compressors,dryer, and pressure vessels, and their interactionwith one another to the actual demand of compres-sed air and the operating conditions of the hospital.For example, by transitioning from a three- to a flexi-ble four- compressor system the installed total out-put can be substantially decreased, while still main-

taining a sufficient safety margin because oneaggregate now only has to cover approx. 50% of themaximum demand for compressed air. By adjustingthe pressure band, compressor performance canbe further optimised, which leads overall to a moreefficient operation and decreases wear and tear. We also benefit from our comprehensive knowledgeof clinical applications when it comes to creating atailor-made design of the system. We consider theinfluence of the increase in the efficiency of clinicaldevices when calculating the maximum compres-sed air demand of the hospital. We will also gladlyhelp you to improve the efficiency of your currentcompressed air system.

Since 2016 a new medical compressed air system manufactured by Dräger has beenproviding patients with vital breathing air in the RoMed Clinic Rosenheim, which wasawarded the "Green Hospital of Bavaria" award.The objective of the refurbishment was an increase in the energy efficiency throughout by installing a modern standardised compressed air system. AugustSchechner, head of the technical department of the RoMed Clinic for over 10 years,appreciates the safety, efficiency and flexibility of the new installation.

Energy-oriented refurbishment of a compressed air system in the RoMed Clinic in Rosenheim

SAFETY

The RoMed Clinic's new compressed airsystem fulfils the safety requirements bymeans of the redundant design of all cri-tical components, as well as systemmonitoring through integration into theBuilding Management System (BMS).During the refurbishment period, a reli-able and interruption-free supply ofmedical compressed air was upheld by afully functional, external emergency sup-ply system. This was most important forMr. Schechner: "There was never animpairment of the supply during therefurbishment period."

EFFICIENCY AND FLEXIBILITY

In order to determine compressed airdemands, Dräger measured consumpti-on under normal operating conditions.This allowed to design an installationtuned to the individual requirements ofthe RoMed Clinic. The result: a systemcomprising four compressors with lowpower input, which operate with a mini-mised load running time, depending onconsumption requirements. By optimi-sing the installation and through heatrecovery, it was possible to reduce ener-gy consumption by 17% as compared tothe previous system.

SERVICE

"A sense of responsibility toward techno-logy is the most important aspect when itcomes to the life of the patients. This isthe case with Dräger." says Mr. Schech-ner. There is close cooperation betweenthe hospital's technical department andthe Dräger service engineers, the qualityand commitment of which he is convin-ced of. Permanent security of the systemis ensured thanks to the fact that the ser-vice engineers are familiar with the work-flows and structures prevailing in the cli-nic, which allows them to perform therequired maintenance work responsibly.

It all comes down to the quality of compressed air.Medical compressed air is essential for the ventila-tion of intensive care patients and, as such, is themost important medical gas apart from oxygen.The quality standards are accordingly high. Inter-national guidelines such as EN ISO 7396-1 and theEuropean Pharmacopoeia prescribe the guaranteeof supply and regular inspection of the quality ofcompressed air. In addition, they define preciselimit values for specific contaminants. Unlike othermedical gases, since medical compressed air isproduced in the hospital itself, the hospital is alsosolely responsible for its quality.

We will help you to fulfil this responsibilityMedical compressed air is produced throughsuction of surrounding air. Its quality can be nega-tively influenced by a number of factors, such ashigh CO2 content, humidity, and impurities. There-fore, regular inspection of the quality of the com-pressed air is essential. Executive managementand technical management must take into considera-tion possible impairments in risk assessment forthe risk and emergency management. Dräger tech-nology will help you to ensure the quality of yourmedical compressed air and to react immediatelyto deviations, so that you can fulfil your responsibilityentirely.

Medical compressed air: a vital gas

There is hardly a gas, which is so widely used in a hospital such as medical compressed

air. Accordingly, the quality standards are high. Dräger technology ensures that relevant

norms and limits are observed.

Common responsibility for medical compressed air quality.

RELIABLE CONDITIONING WITH MEDICAL AIR ENSURE

Only through standardised filtering and drying, compressed air becomes an appro-ved medical product. The Dräger Medical Air Ensure (MAE) reliably fulfills this task.The certified conditioning unit is a modern compressed air purification device thatmeets international requirements and allows for safe mechanical and hygienic operation of the system. The MAE has also been proven to cope easily with high pollution of the surrounding air. Keeping within the limit values under real conditionswas carefully tested in the laboratory. The MAE sets standards with regard to energyefficiency as a result of precise design and dimensioning to fit the compressor system, individual adaptation to environmental conditions, and an outstanding ratio of performance to energy usage.

CONTINUOUS MONITORING WITH MEDICAL AIR GUARD

The Medical Air Guard (MAG) continuously monitors the purity of the medical compressed air in line with the European Pharmacopoeia. Thanks to the proven Dräger sensor technology, gaseous impurities, oxygen content, dew point, and volatile organic compounds (e.g. oil vapours) can be measured precisely. This way, even a brief entry of contaminants can be discovered reliably. The system automatically sets off a warning as soon as a limit value is exceeded. All measurements and alarms are displayed on the device itself and can be madeavailable for further evaluation by means of an interface. This allows for seamlessdocumentation of the compressed air quality in your hospital.

OPTIMAL OVERVIEW WITH THE GAS COMMUNICATION COCKPIT – GCC 1000

With the Gas Communication Cockpit – GCC 1000 you also get an optimal over-view of the quality of the medical compressed air outside of the central compressedair system. Alarms and measurements stemming from the Medical Air Guard or anyother medical air system component are clearly visualised on an 8.4-inch touchpanel. In addition, the integrated web interface offers supervisors the capability ofaccessing all data from anywhere. This allows them to react faster to possible crossing of parameters prescribed for the quality of compressed air. Data loggersand additional communication interfaces complete the system and help to ensuresecurity in the supply from the medical compressed air installation. Likewise, theyoptimise the hospital's alarm and emergency management.

Innovative technology for top quality compressed air

Thanks to Dräger's innovative solutions you have the medical compressed air quality

under control: from production to continuous monitoring, all the way to seamless

documentation and immediate alerting if needed.
