Purification construction requirements of intensive care unit
1. The number of ICU beds is generally set at 3-5% of the total beds in the hospital. Each ICU management unit should have 8-12 beds, and the utilization rate of beds should be controlled within 65-75%.
2. The open bed in ICU covers an area of 15~18 square meters; Each ICU is equipped with one less single ward, covering an area of 18~25 square meters. The establishment of positive pressure and negative pressure isolation wards in each ICU is usually equipped with 1~2 negative pressure isolation wards.
3. In terms of geographical location, ICU should choose an area that is convenient for patient transfer, examination and treatment, and consider the following factors: proximity to the main service object ward, operating room, imaging discipline, laboratory and blood bank. When horizontal "proximity" cannot be achieved, vertical "proximity" upstairs and downstairs should be considered.
4. The basic auxiliary rooms of ICU include doctor's office, director's office, staff rest room, treatment room, dispensing room, instrument room, changing room, cleaning room, sewage and waste treatment room, duty room, washroom, etc. If possible, ICU can be equipped with other auxiliary rooms, including display room, family reception room, laboratory, nutrition preparation room, etc. The ratio of auxiliary room area to ward area shall be more than 1.5:1.
5. The overall layout of ICU should make the medical area, auxiliary medical room area, sewage treatment area and auxiliary living room area for medical staff where hospital beds are placed relatively independent, so as to reduce mutual interference and facilitate the control of infection.
6. ICU shall have good ventilation and lighting conditions. If possible, it shall be equipped with a vertical laminar air purification system, which can independently control the indoor temperature and humidity. The temperature in the medical area shall be maintained at about 24 ℃, and the air conditioning system of each single room shall be controlled independently. In addition, sufficient inductive hand washing facilities and hand disinfection devices shall be installed, with one set for each bed in a single room and at least one set for each two beds in an open hospital bed.
7. ICU should control the flow of people and logistics, including the flow of people and logistics. There should be a reasonable flow of medical care through different access channels, so as to reduce various interference and cross infection as much as possible.
8. The building decoration of ICU Wards shall follow the general principles of no dust generation, no dust accumulation, corrosion resistance, moisture and mildew resistance, anti-static, easy cleaning and meeting the fire prevention requirements.
9. The ICU shall be designed to provide convenient observation conditions for medical staff and access to patients as soon as necessary.
10. The ICU ward should be quiet. In addition to the call signal of patients and the alarm sound of monitoring instruments, the sound of telephone ringing, printers and other instruments belong to the noise of ICU. These sounds shall be reduced to the lowest possible level without affecting normal operation. According to the recommendations of the international noise Association, the noise in ICU shall not exceed 45 dB in the daytime, 40 dB in the evening and 20 dB at night. Floor coverings, walls and ceilings shall be made of building materials with good sound absorption performance as far as possible.
11. ICU should establish a complete communication system, network and clinical information management system and broadcasting system.
