Don’t be nervous about air entering your blood vessels. For a 50kg adult woman, 10mL of air or less is relatively safe. According to some data, an adult needs 400mL of air to be lethal, but in fact, the lethal amount of air does not need to be so much, only need more than 2mL/kg of air into the body may have the risk of sudden death. Again, for an adult 50kg female, at least 100mL of air would be needed and should be injected into the body within a minute for this to happen, so it is less likely to occur. However, if this happens, the patient can be placed in the head-down position and left lateral recumbency, so that the air enters the right ventricle, avoiding the entrance of the pulmonary artery, and due to the beating of the heart, the air is mixed into foam and enters the pulmonary artery in small quantities in several stages, and the patient is immediately given pure oxygen, and hyperbaric oxygen treatment can be carried out if possible. If the patient develops cerebral convulsions valium can be used, hormones can also be used to reduce cerebral edema, heparin and small molecule dextrose anhydride can be applied to improve the circulation, and the condition can continue to be observed until the patient proves to be completely out of danger. Because death from air embolism is uncommon and required in large quantities, it is important not to become overly stressed.
