Bloodgas coefficients and induction
WebIn the present study of human tissues, we found that the tissue/blood partition coefficients (for brain, heart, liver, kidney, muscle, and fat) for the new anesthetic I-653 were smaller than those for isoflurane, sevoflurane, and halothane (anesthetics listed in order of increasing tissue/blood partition coefficients). WebThe low solubility in blood results in a moderately rapid induction, recovery and rate of change of anesthetic depth. Solubility in tissues such as muscle and fat is quite high …

Since the blood flow in the body tissues varies there is a certain order in ... •Lowest blood/gas coefficient of all inhalant anesthetics (0.42) - fastest induction onset. •Low boiling temperature - requires a special heated vaporizer. 28 . WebWater/gas and blood/gas coefficients are 1.55 and 9.15 respectively as measured by spectrophotometry (Powell, 1947). An oil/gas value of 960 is quoted by Mapleson (1963), but the experimental data are unpublished. Chloroform. A 10.3 blood/gas coefficient is found by a complex chemical gas extraction technique (Nicloux and Scotti-Foglieni, 1929).
