Hospitals and clinics are among the facilities with high air quality requirements. The organization of air conditioning and ventilation systems in hospitals and polyclinics is mandatory – this is provided for in regulations. According to these standards, air conditioning must be organized on a mandatory basis in anesthesia, operating and postoperative wards, in prenatal, delivery and intensive care rooms, in burn departments and pressure chambers, in wards for premature babies, newborns and infants, in intensive care units and etc.
Malfunctions in the ventilation systems in hospitals can lead to a deterioration in the health of patients, to the spread of infections in the premises. The air entering the departments and chambers must undergo bacteriological treatment using special filters. In addition, there are standards for temperature and humidity levels in different rooms. The standards also stipulate the speed of movement of air flows, which should not exceed 0.15 m / s, otherwise drafts may occur, which is not permissible in hospitals.
In order for the ventilation in the hospital to maintain an air climate that meets sanitary standards, the system must be correctly designed and correctly installed. That is why it is important that professionals with extensive experience in this field are involved in ventilation at all stages. Bio Medical Engineering employs specialists who are able to professionally and quickly carry out all ventilation work from design, installation and assembly to commissioning.
Design, calculation and installation of ventilation for medical institutions, whether it is ventilation of a polyclinic or ventilation of a hospital, is reduced to meeting the main sanitary requirement – ventilation must provide an antiseptic air environment in the premises. The peculiarity of ventilation in hospitals and clinics is the selection of air modes for each room, since hospitals have blocks and departments of various purposes. This is the difficulty in creating multifunctional forced-air supply and exhaust ventilation systems.
In view of this complexity, the creation of a single ventilation system for all premises is unacceptable, therefore, it is necessary to provide separate ventilation systems for resuscitation rooms, for operating units, for laboratories, X-ray departments, utility blocks, etc. One ventilation system is allowed to serve only wards of one purpose if it is not an infectious ward.
In many hospital rooms, only exhaust ventilation is allowed, with supply air being supplied to a common corridor or lobby. Supply and exhaust ventilation systems are installed in medical institutions and pharmacies. When organizing ventilation systems in hospitals, strict requirements are imposed on the location of ventilation units. The noise level from operating fans in rooms should not exceed 35 dBA.
