During laparoscopic surgery, carbon dioxide is insufflated for expanding the abdominal volume. However, the abdominal compliance identifies the critical point over the Pressure-Volume (P-V) curve beyond which the patient is exposed to harmful effects. Calculating this point is, therefore, critical. We aim to model a P-V curve for pediatric patients by fitting a sigmoidal equation with the Levenberg-Marquardt algorithm.

Abstract
During laparoscopic surgery, carbon dioxide is insufflated for expanding the abdominal volume. However, the abdominal compliance identifies the critical point over the Pressure-Volume (P-V) curve beyond which the patient is exposed to harmful effects. Calculating this point is, therefore, critical. We aim to model a P-V curve for pediatric patients by fitting a sigmoidal equation with the Levenberg-Marquardt algorithm.File in questo prodotto:
