The interior of modern ambulances is quite spacious, so that paramedics have enough space to go to the hospital on the way to rescue patients. Modern ambulances also carry a large number of bandages and external application, which can help stop bleeding, clean wounds, and prevent infection. The car is also equipped with splints and brackets, which are used to fix the patient's broken limbs to avoid aggravation of neck and spine injuries. The car is also equipped with oxygen, a portable ventilator and a pacemaker defibrillator. Most ambulances also have patient monitors, which monitor the patient’s pulse and breathing on the way to the emergency room. These test data can be transmitted to the hospital via radio.
Many modern ambulance personnel are professional first aid personnel, especially those responsible for high-risk situations such as large-scale sports events and busy road sections. They can provide high-level first aid treatment. Their professional rescue at the scene and on the way can often save the lives of the injured.
