It is not necessary to be too nervous to have air infusion by sling injection. You can take the left side position with head low and feet high first, so that the gas cannot enter the right ventricle and pulmonary artery in a large amount, and give oxygen at the same time, and you can also enter the hyperbaric chamber for oxygen when the condition is better. For a woman with 50kg body weight, the amount of air embolism causing death is around 100mL, while air below 10mL will not cause obvious clinical symptoms and will have no obvious effect on health, and will be absorbed by the organism soon. To prevent this from happening again, it is important to keep an eye on the infusion tube during infusion.
