Automatic tube compensation (ATC) is a feature of mechanical ventilation that compensates for the additional work of breathing caused by the resistance of the endotracheal or tracheostomy tube. When a patient is intubated, the tube can cause additional resistance, which makes it more difficult for the patient to breathe. This additional work of breathing can be particularly challenging for patients with lung disease or respiratory muscle weakness. ATC addresses this issue by automatically adjusting the ventilator's pressure support to compensate for the resistance of the endotracheal or tracheostomy tube. This means that the ventilator delivers a greater amount of pressure support during inspiration to help the patient overcome the resistance of the tube, reducing the work of breathing. It is especially beneficial during SBTs.

Inspiratory Pressure Rise Time is a parameter in pressure-delivered breaths on mechanical ventilation that refers to the time it takes for the ventilator to reach the set inspiratory pressure. It is the duration from the start of the inspiratory phase to the point at which the pressure in the patient's airways reaches the desired level.

This video provides a detailed explanation of the parameters of oxygenation and how to optimize them to improve patient outcomes. The video starts by introducing the importance of oxygenation in mechanical ventilation and the parameters that affect it, including FiO2 and mean airway pressure (MAP). Dr. Kherallah then explains how to maximize MAP to improve oxygenation in patients with severe hypoxemia who are on 100% FiO2. The video goes on to describe various methods of maximizing MAP, such as increasing positive end-expiratory pressure (PEEP), extending inspiratory time, increasing tidal volume or plateau pressure, increasing rise time (on pressure control mode of ventilation), and increasing respiratory rate. Dr. Kherallah explains the advantages and disadvantages of each method and how to choose the appropriate one based on the patient's condition. Throughout the video, the instructor uses clear and concise explanations, as well as visual aids, to help viewers understand the concepts of oxygenation and its optimization in mechanical ventilation. The video is an excellent resource for healthcare professionals who manage patients on mechanical ventilation.
