Abstract

Endotracheal tubes (ET) are used to provide patients with an adequate airway when they are unable to breathe on their own. ET tubes can be used in emergency situations, surgical procedures, and on-floor intubations. The two main types of ET tubes are cuffed and uncuffed. Due to the fragile structure of a child's throat, uncuffed tubes are primarily used in pediatric patients. Uncuffed tubes can slip out of place resulting in air leakage and improper oxygenation. In contrast, cuffed ET tubes provide a proper seal to the airway and prevent against aspiration. The following work proposes an improved design for cuffed ET tubes that can be used in pediatric patients.
