ICU ward purification project

Intensive Care Unit Laminar Flow Ward

With the development of medical technology, the number of difficult surgeries such as heart, head, and organ transplants continues to rise. Controlling postoperative infection rates, avoiding cross infection, and ensuring surgical success rates have become increasingly important. Clean technology in operating rooms and ICU wards, which is crucial for life safety, is crucial.

ICU is an abbreviation for Intensive Care Unit in English, which means intensive care unit. It admits patients with respiratory, circulatory, metabolic, and other systemic functional failures from various departments such as internal medicine and surgery, and provides them with strong systemic management of respiratory, circulatory, metabolic, and other functions.

ICU ward construction standards:

（1） ICU should have a special geographical location, set up in an area that is convenient for patient transportation, examination, and treatment, and consider the following factors: proximity to the main service areas such as wards, operating rooms, imaging departments, laboratories, and blood banks. When horizontal "proximity" cannot be achieved, vertical "proximity" between the upper and lower floors should be considered.

（2） The floor area of each ICU open bed is 15-18M2; Each ICU is equipped with at least one single room ward, with an area of 18-25M2. The establishment of positive and negative pressure isolation wards in each ICU can be determined based on the patient's specialized source and the requirements of the health administrative department, usually equipped with 1-2 negative pressure isolation wards. Encourage the design of single rooms or partitioned wards with sufficient human resources.

（3） The basic auxiliary rooms of ICU include physician's office, director's office, staff lounge, central workstation, treatment room, dispensing room, instrument room, changing room, cleaning room, waste disposal room, duty room, washroom, etc. Conditional ICUs can be equipped with other auxiliary rooms, including demonstration rooms, family reception rooms, laboratories, nutrition preparation rooms, etc. The ratio of auxiliary room area to room area should be at least 1.5:1.

（4） The overall layout of the ICU should ensure that the medical areas where beds are placed, the medical auxiliary rooms, the waste treatment areas, and the medical staff living auxiliary rooms have relative independence, in order to reduce mutual interference and facilitate infection control.

（5） ICU should have good ventilation and lighting conditions. For those who have the conditions, it is best to install an air purification system with airflow direction from top to bottom, which can independently control the indoor temperature and humidity. The temperature in the medical area should be maintained at around (24 ± 1.5) ℃. The air conditioning system of each individual room should be independently controlled. Install sufficient induction based hand washing facilities and hand disinfection devices, with one set per single bed and at least one set per two open beds.

（6） ICU should have a reasonable medical flow, including personnel and logistics, preferably achieved through different entry and exit channels to minimize various interferences and cross infections.

（7） The decoration of ICU ward buildings must follow the general principles of no dust production, no dust accumulation, corrosion resistance, moisture and mold resistance, anti-static, easy cleaning, and compliance with fire prevention requirements.

（8） The design requirements of ICU should meet the needs of providing convenient observation conditions for medical staff and access to patients as soon as necessary.

（9） In addition to the patient's call signal and the alarm sound of monitoring instruments, the sound of phone ringtones, printers, and other instruments are all considered ICU noise. These sounds should be minimized as much as possible without affecting normal work. According to the recommendations of the International Noise Association, it is best not to exceed 45 decibels (A) of ICU noise during the day, 40 decibels (A) in the evening, and 20 decibels (A) at night. Floor coverings, walls, and ceilings should be made of high sound absorbing building materials as much as possible.

（10） ICU should establish a comprehensive communication system, network and clinical information management system, and broadcasting system.
