The Physiology of Breath Delivery and Modes of Mechanical Ventilation

Video Transcription

Video Summary

The video is a lecture on the physiology of breath delivery and its applications to patient ventilator interaction. The lecturer discusses the various components of a respiratory cycle, including trigger, breath delivery, cycle, and exhalation. He explains how the breath is turned on and delivered to the patient using a pressure gradient and resistance. The equation of motion, which describes how the breath is delivered, is also discussed. The lecturer then goes on to explain how the breath turns off and how the cycle is determined based on the control variable (volume, time, or flow). Finally, the lecturer demonstrates the clinical application of these concepts by analyzing different scenarios where a patient is interactively or passively inspiring. The lecture emphasizes the importance of understanding these concepts in order to effectively manage patient ventilator interactions.
