An air embolism of 10 ml or more can lead to death of the patient. If the air embolism reaches 50ml or more, it can rapidly lead to the death of the patient. So this situation must be treated in time to avoid the air entering the blood circulation and entering the blood vessels during the intravenous infusion or static drug pushing, both of which can cause serious sequelae. If the amount of air entering is small, within 5ml, no special treatment can be done. Because a small amount of gas will be absorbed quickly in the blood circulation and will not cause any harm to the body. If it is between 5 and 10 ml, the patient should be observed and treated, and if there are uncomfortable symptoms, timely symptomatic treatment should be given, and if there are no uncomfortable symptoms, no special treatment should be done. If 10ml or more, the patient should be monitored and treated. In this case, it may lead to air embolism at any time, resulting in loss of control of the patient’s life, which must be dealt with in a timely manner to avoid leading to the patient’s death.
