Comparison of Mask Ventilation in Obese Patients by Differents One Hand Techniques

"The E-C clamp technique involves forming a C with the thumb and index finger around the mask while the remaining fingers form an E to lift the mandible. This technique aims to provide a good seal while opening the airway."

"The T-E technique is a variation where the thumb and index finger form a T over the mask while the other fingers provide chin lift and jaw thrust.~This method is designed to optimize airway patency and mask seal. While these techniques are widely taught and practiced, they often fall short in obese patients due to the difficulty in maintaining an adequate seal and achieving sufficient ventilation pressures. Complications such as hypoxemia and gastric insufflation are more common in this population."

e is a novel method for single-hand ventilation that has shown promise in preliminary studies. This technique involves a unique hand positioning that aims to improve mask seal and ventilation efficacy, particularly in patients with challenging airway anatomy. In Hook Technique using the thumb and index finger to form a hook around the mask, creating a more secure and adjustable seal and utilizing the remaining fingers to apply consistent mandibular lift, enhancing airway patency.
