  In medicine, up to 5% carbon dioxide (130 times atmospheric concentration) is added to oxygen for stimulation of breathing after apnea and to stabilize the O / CO balance in blood.
  
  Carbon dioxide can be mixed with up to 50% oxygen, forming an inhalable gas; this is known as Carbogen and has a variety of medical and research uses.
  
  Another medical use are the mofette, dry spas that use carbon dioxide from post-volcanic discharge for therapeutic purposes.
