Design and Implementation of Capnograph for Laparoscopic Surgery

Daniel Santoso and Fransiscus Dalu Setiaji
Abstract— Capnography is a non-invasive method of monitoring the concentration of partial pressure of carbon dioxide. Nowadays, the application of capnography is a standard for general anesthesia. In this research, we design and implement sidestream capnograph based on microcontroller that can estimate the concentration of CO2 in the respiratory gases and measure respiratory rate. The accuracy of the prototype EtCO2 and RR has been verified relative to NT1D Series Handheld Vital Signs Monitor from Solaris Medical Technology Inc. in two chances of operation. The overall bias for EtCO2 based on relative verification between prototype and NT1D Series is 5.58% and -1.17% respectively whereas the overall bias for RR is -0.62 bpm and -0.29 bpm respectively. The correction feature to handle interference due to presence of gases such as sevoflurane, N2O and O2 is also implemented in the firmware.

Index Terms— End-tidal CO2 rate, sidestream capnograph.
