Continuous monitoring of ventilation by diaphragm ultrasonography using a new tool during procedural sedation

The number of procedures performed under sedation has increased, and so there is a need for a continuous respiratory monitoring for the initiation of interventions to prevent risk factors due to the ventilatory depression. However, continuous monitoring methods, such as clinical observation, pulse oximetry and capnography, are known to have limitations [1, 2]. The respiration is primarily driven by the diaphragm motion, and ultrasonography (USG) can be used for assessment of the diaphragm [3]. Transthoracic diaphragm USG used for evaluating the thickness, contractile activity, function or predicting extubation during the mechanical ventilation in intensive care units (ICUs) [4, 5].
