Скачать или смотреть The Patient with High Airway Pressures - Part 2

(note: this video has been updated to correct some mistakes)
In the previous tutorial we looked at the problem of high airway pressures and addressed inspiratory airway resistance in two ways: peak to plateau pressure gradient and dynamic and static inspiratory resistance.
In this tutorial we will look at three more ways of assessing airflow resistance: the identification and measurement of Auto-PEEP, Flow-Volume Loops and capnography.
Subsequently I discuss high airway pressure due to low total respiratory system compliance. I explain that when "compliance" is low - this may be a problem with the lungs as well as the chest wall - including the abdomen. I finish with the introduction into this course of Abdominal Compartment Syndrome.
