Variables and Initial Settings | Mechanical Ventilation | Little Criticos ===========================================================
In this series we discuss basics of mechanical ventilation.
In part 3 of this series, we discuss the key variables that control ventilation and the initial settings to be chosen while ventilating.
The parameters discussed include tidal Volume, flow, pressure, peak inspiratory pressure, positive end expiratory pressure, FiO2, respiratory rate, breath cycle time and their graphical representations.
We also briefly discuss types of compliance, resistance and the concept of time constan

Good summary of the initial settings. MUST watch for all postgrads and intensive care fellows. One suggestion: please post link of additional reading/ references at the end of each video.

[@LittleCriticos]

Thank you.
We will definitely include your suggestions in future.

Thank you so much, sir. This was an excellent summary for me. I wish I could have watched it as an introduction to Mech-Vent instead of reading textbooks. I would love to donate. How can I?

[@LittleCriticos]

Thank you so much for the kind words. Happy to know that videos are helpful.

Beautifully explained.WEll Done

Thanks a lot Dr. Pavithra.
Your suggestions are welcome.

17 :50 as in graph Te is also responsible for increasing mean airway pressure..how to interpret this. .

[@LittleCriticos]

Thank you for Ritesh.
MAP is influenced by the duration of PEEP during Te. However, in clinical context we cannot separate Ti and Te as they are interdependent.
So when you increase Ti (area under both PEEP and Delta P Increase) and in Te only PEEP changes when the rate is not altered as seen in the graph. So the formula takes into account this.
Hope this answers your query.

@@LittleCriticos Respected Sir but as seen in the graph @17:50, when RR is increased the next cycle begins earlier...so wont the AUC decrease as now the graph is abbreviated ?
