Implementation of a Pharmacokinetic Model for Inhaled Anesthetics Into a Software-Based Anesthesia Workstation for LLEAP-Compatible Simulators

Abstract

Introduction 

Laerdal Learning Application (LLEAP)-compatible simulation manikins lack some specific functions that can be useful in anesthesia simulation scenarios. Our objective was to develop a software-based anesthesia workstation with a pharmacokinetic model for inhaled anesthetics for this simulation platform.

Methods 

A Windows Presentation Foundation application that emulates an Aespire anesthesia workstation was created. The Gas Man simulator (Med Man Simulations) was used as a reference for the pharmacokinetic model. A concordance analysis was made between the results obtained by our model and the reference, in open and semiclosed circuit, in both 70- and 140-kg patients.

Results 

The mean of the differences between the compartments was less than 0.01 vol% in all circumstances. The percentile rank P2.5 to P97.5 was less than 0.5 vol% in all compartments, except for the open circuit compartment.

Conclusions 

No significant differences were found between both pharmacokinetic models. We consider that our software-based anesthesia workstation can be useful for simulating mechanical ventilation and halogenated administration in different scenarios.
