Blood–gas partition coefficient, also known as Ostwald coefficient for blood–gas, is a term used in pharmacology to describe the solubility of inhaled general anesthetics in blood. According to Henry's law, the ratio of the concentration in blood to the concentration in gas that is in contact with that blood, when the partial pressure in both compartments is equal, is nearly constant at sufficiently low concentrations. The partition coefficient is defined as this ratio and, therefore, has no units. The concentration of the anesthetic in blood includes the portion that is undissolved in plasma and the portion that is dissolved (bound to plasma proteins). The more soluble the inhaled anesthetic is in blood compared to in air, the more it binds to plasma proteins in the blood and the higher t

  • Blood–gas partition coefficient, also known as Ostwald coefficient for blood–gas, is a term used in pharmacology to describe the solubility of inhaled general anesthetics in blood. According to Henry's law, the ratio of the concentration in blood to the concentration in gas that is in contact with that blood, when the partial pressure in both compartments is equal, is nearly constant at sufficiently low concentrations. The partition coefficient is defined as this ratio and, therefore, has no units. The concentration of the anesthetic in blood includes the portion that is undissolved in plasma and the portion that is dissolved (bound to plasma proteins). The more soluble the inhaled anesthetic is in blood compared to in air, the more it binds to plasma proteins in the blood and the higher the blood–gas partition coefficient. It is inversely related to . Induction rate is defined as the speed at which an agent produces anesthesia. The higher the blood:gas partition coefficient, the lower will be the induction rate. Newer anesthetics (such as desflurane) typically have smaller blood–gas partition coefficients than older ones (such as ether); this leads to faster onset of anesthesia and faster emergence from anesthesia once application of the anesthetic is stopped, which may be preferable in certain clinical scenarios. If an anesthetic has a high coefficient, then a large amount of it will have to be taken up in the body's blood before being passed on to the fatty (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.

  • El coeficiente de reparto sangre-gas, también conocido como coeficiente de Ostwald para sangre-gas,​ es un término utilizado en farmacología para describir la solubilidad de los anestésicos generales inhalados en la sangre.​ El coeficiente se define como la relación entre la concentración en sangre y la concentración en gas que está en contacto con esa sangre, cuando la presión parcial en ambos compartimentos es igual. El coeficiente, por lo tanto, no tiene unidades. La concentración del anestésico en la sangre incluye la porción que no se disuelve en plasma y la porción que se disuelve (unida a las proteínas plasmáticas). Cuanto más soluble es el anestésico inhalado en la sangre en comparación con el aire, más se une a las proteínas plasmáticas en la sangre y mayor es el coeficiente de reparto sangre-gas. Está inversamente relacionado con la tasa de inducción. Los anestésicos más nuevos (como el desflurano) suelen tener coeficientes de partición de gases en sangre más pequeños que los más antiguos (como el éter); estos se prefieren porque conducen a un inicio más rápido de la anestesia y a una emergencia más rápida de la anestesia una vez que se detiene la aplicación del anestésico.​​ Si un anestésico tiene un coeficiente alto, entonces deberá absorberse una gran cantidad en la sangre del cuerpo antes de pasar a los tejidos grasos (lípidos) del cerebro donde puede ejercer su efecto. La potencia de un anestésico está asociada con su solubilidad en lípidos, que se mide por su coeficiente de reparto aceite/gas.​ La concentración alveolar mínima (MAC) se define como la concentración alveolar de gas anestésico que impide una respuesta de movimiento en la mitad de los sujetos que sufren un estímulo doloroso (quirúrgico); simplificado, es la concentración de gas exhalado requerida para producir efectos anestésicos, un indicador inverso de la potencia del gas anestésico.
