How do you treat low blood oxygen levels?
In some cases, a doctor may give a patient medication or an inhaler to control breathing, explains WebMD. Steroids, for instance, may help to shrink lung inflammation. If a patient’s life is in danger, a doctor may use a machine to help the individual breathe. Some of the signs that a person has low oxygen in the blood include changes in the color of the skin, coughing, confusion, a fast heart rate and rapid breathing. Patients also may experience sweating, wheezing and shortness of breath.
