Blood is extremely dangerous when carried to the blood via the lungs by inhalation, because carbon monoxide irreversibly binds to hemoglobin to form carboxyhemoglobin, so that less hemoglobin is free to bind oxygen, and fewer oxygen molecules can be transported throughout the blood. This can cause suffocation insidiously. A fire burning in an enclosed room with poor ventilation presents a very dangerous hazard, since it can create a build-up of carbon monoxide in the air. Some carbon monoxide binds to hemoglobin when smoking tobacco. Blood for transfusion is obtained from human donors by blood donation and stored in a blood bank.
Blood–gas partition coefficient (lipid) tissues of the brain where it can exert its effect. The potency of an anesthetic is associated with its lipid solubility which is measured by its oil/gas partition coefficient. Minimum Alveolar Concentration (MAC) is defined as the alveolar concentration of anesthetic gas that prevents a movement response in half of subjects undergoing a painful (surgical) stimulus; simplified, it is the exhaled gas concentration required to produce anaesthetic effects - an inverse indicator of anesthetic gas potency. Partition coefficients at 37 °C. Blood–gas partition coefficient Blood–gas partition coefficient, also known as Ostwald coefficient for blood–gas, is a term used in
