Mechanical ventilation is the safest method. The most common injuries that need breathing are arterial gas embolism, carbon monoxide poisoning, and soft tissue infections. The patient's lungs are supplied with more oxygen via the use of the ventilator, which forces a combination of air and oxygen into the airways. To prevent the air sacs in the lungs from collapsing, the ventilator can maintain a continuous quantity of positive end-expiratory pressure (PEEP), also known as low pressure.
