What is the difference between negative pressure ambulance and ordinary ambulance?

One, the facilities are different

1, negative pressure ambulance: the car is also equipped with a respirator, defibrillator, cardiac monitor and other full set of rescue equipment, installed ultraviolet disinfection lamps, central oxygen interface.

2, ordinary ambulance: the car also carries splints and brackets used to fix the patient's broken limbs, and to avoid the patient's neck and spine injury aggravation. The car is also equipped with oxygen, portable ventilators and defibrillators. Most ambulances also have patient monitors that can monitor a patient's pulse and breathing on the way to the emergency room.

Two, different features

1, negative pressure ambulance: the so-called negative pressure, is the use of technical means, so that the air pressure inside the car is lower than the outside atmospheric pressure, so the air in the free flow can only be outside the car to the car, and the negative pressure can be harmless treatment of the air inside the car after the discharge, to avoid more people infected, in the rescue and transportation of infectious diseases and other special diseases can be maximized to Reduce the chance of cross-infection of medical personnel.

2, ordinary ambulance: modern ambulances are more spacious inside, so that ambulance personnel have enough space to go to the hospital on the way to the patient rescue treatment. Modern ambulances also carry a large number of bandages and dressings to help stop bleeding, clean wounds and prevent infection.

Extended information

Technical requirements

National Ministry of Health requirements: 20 air changes per hour, the negative pressure value of -10Pa to -38Pa between the filtration and separation rate of 99.9% of negative pressure ambulance patient cabin negative pressure refers to the cabin and the outside world the relative pressure difference between the atmosphere, relying on the exhaust fan To the outside atmosphere active exhaust and sealing of the cabin to realize.

The air inside the patient's cabin is generally filtered by a high efficiency filter (99.97%@0.3um) before it is discharged to the atmosphere, which can effectively reduce the spread of microorganisms to the ambulance to the outside environment, pollution. This method is only a physical isolation method, bacteria, viruses are intercepted on the surface of the high-efficiency filter, can not kill, ambulances should be used after the disinfection for the cabin.
