Nobukazu Sato, Making MAC calculation application for desflurane using MIT App Inventor 2.(2016)SDRP Journal Of Anesthesia & Surgery 1(2)
To calculate age-corrected MAC value of inhalation anesthetics, we made android application. Mapleson\'s formula was used for the calculation of MAC in this application.
For programming the application, we used MIT app inventor 2 designed to create android application, which easily combines the blocks of numerical formula and logical elements without knowledge of programming language to make application. We calculated the MAC value with this application, and found the estimated MAC values were slightly higher in elderly people than the values we knew. We developed an application for calculating MAC of inhaled anesthetics and found an overestimation of MAC exists in the elderly compared with the values prepared by the industry, but overestimation is thought to be safe when we aim for preventing perioperative awakening.
