The causes of 86% blood oxygen include pneumothorax, heart failure, lung infection, etc. Thoracentesis and aspiration, oxygenation, anti-infection and other treatments can be taken.
1. Pneumothorax: gas compression of lung tissue, resulting in a decrease in blood oxygen, at this time to be chest puncture suction or closed chest drainage, to be discharged after the gas chest tightness symptoms improve, blood oxygen will rise.
2. Heart failure: in acute heart failure, chest tightness and shortness of breath are obvious, and blood oxygen decreases, sitting position, low-flow oxygen inhalation, and then cardiotonic (digoxin), diuretic (furosemide) and other treatments.
3. Lung infection: severe lung infection, blood oxygen drop can occur, need to be given antibiotic anti-infection treatment, such as moxifloxacin, sodium cephalosporin, etc., and at the same time be given oxygen.
Blood oxygen 86%, there are many reasons for the decline, need to consult a doctor. Follow the doctor’s instructions for medication.
