Abstract
An improved therapy for both clearing the blood of unwanted carbon monoxide and anaesthetic chemicals and for rapidly re-oxygenating blood suffering from carbon monoxide poisoning or smoke inhalation. It also includes a therapy delivery device for carbon dioxide and oxygen metering and mixing apparatus for gases under pressure particularly for respirators and medical devices which has a plurality of compressed gas supply lines which are connected to a mixing device for delivery into a demand regulator (respirator or face mask). It includes a gas selection device, an automatic shut off of the carbon dioxide, a purging system, metering of the gases and a mixing chamber to promote a homogeneous mixture of gases and sized for field use by emergency care operators. The therapy is a mixture of carbon dioxide and oxygen for promoting the rapid oxygenation of the patient's blood supply for cases of carbon monoxide poisoning, smoke inhalation or other cases where the blood oxygen level is low.
