La mayoría de las leyes de los gases, cumplen con la denominación de gases ideales. La mayoría de los gases anestésicos solo cumplen las leyes de los gases perfectos, en un rango de temperatura y presiones muy pequeño, dado que muchos de ellos a temperaturas ambientales son líquidos. Al referirnos a los gases, hemos de considerar las principales características físicas implicadas: volumen, temperatura, humedad y presión, también habrá que considerar la cantidad de gas.]]></p></abstract>
