I'm not a medical professional but remember a very interesting time in my 20s working in a very busy OD in London...and maybe hadn't the courage or means to push on...you h have excellent delivery and clear love for the subject...jeez inhalation gases..effective but hard to measure ...a few puffs of ether would probably suffice less than 100 years ago..the PK/PD profiles of these drugs seem to be specific to a point....I guess there is a lot of presumption about these issues..Keep experimenting..
Dear viewer, If you found this video helpful, I suggest you also watch this one on the subject of MAC (minimum alveolar concentration). czcams.com/video/mfrPC2b6OxU/video.html Kind regards, Stuart
Is the Va:FRC ratio a simplification of the whole machine time constant which takes into account the volume of the circuit (FRC+circuit volume) and all flows (Minute ventilation + fresh gas flow) or are those seperate concepts?
My understanding is that they are separate: >>FGF : circuit volume gives rise to a time constant for the circle >>VA : FRC gives rise to a time constant for the lungs Clearly, low FGF will reduce the rate of rise of partial pressure in the FRC However, time constants refer to the rate of equilibration rather than the rate of rise Hope this helps

Yep, I love this topic!
Very nice , brief and helpful. Thanks

the only useful thing i got from this video was the book the lecturer kept referencing to
