“Our deeds determine us, as much as we determine our deeds.”
Considering the independent and dependent variables of ventilation marked my final contribution to the “Hospitalist and the Resuscitationist” conference in Montreal, Canada; I gave a workshop on graphical analyses of ventilation. This began with the basics of spontaneous breathing and advanced to machine assistance – both discussed under the banner of the respiratory equation of motion. The theory was then used to illustrate the basic meaning of the flow and pressure graphics displayed on nearly all ventilators and provide the essentials for waveform analysis with special attention paid to synchrony.
After watching the video below, consider exploring these recent observations on the mechanical power, driving power and the respiratory system compliance curve. How do each of these concepts fit into the basic mechanics of spontaneous ventilation? How might this be adapted to airway pressure release ventilation? For further viewing, consider these additional videos.
