Great upload👌🏻...really needed a simple explanation in short time

A variation in different literature suggests the vapor pressure of Isoflurane is lower than Halothane (238 mmHg and 243 mmHg, respectively). Also, some literature states that using Isoflurane to fill a Halothane vaporizer results in a Lower concentration output. I just wanted you to know that including this could be controversial and confusing, as I spent several hours on the concept. Reference: Ehrenwerth, J., Eisenkraft, J. B., & Berry, J. M. (2021).

Can you/someone please explain the pumping & pressurising effect, specifically? The above flow chart is very nicely prepared. Thanks.

The pumping effect occurs as minute volume divider ventilators exert a pulsatile back pressure as they cycle. This pressure forces some of the gas exiting the outlet port back into the vaporizing chamber, where more vapour is added. Retrograde flow may also contaminate the bypass channel. These effects cause an increase in the inspired concentration of the agent which may be toxic. These pressure fluctuations can be compensated for by having a) a long inlet port into the vaporizing chamber b) downstream flow restrictors c) having both the bypass channel and the vaporizing chamber being of equal volumes so gas expansion and compression are equal. -Reference: Al Shaikh B et al. Essentials of Anaesthetic Equipment, 4th edition. Elsevier, 2013, Pages 39-40 'Pumping effect - pulsatile back-pressure increases output, especially obvious with older vapourisers, at low flows, and with large pressure swings. Increasing back-pressure will compress gas in the plenum chamber. When the back-pressure drops, vapour-laden gas in the chamber will re-expand and try to get out. It can get out via either the inlet or the outlet line. Via the inlet line, fully-saturated gas can mix with and contaminate the bypass gas. If there is a short connection between the vapour chamber and the outlet line, pumping back and forth between the two will also increase output. Modern vapourisers have overcome this with smaller vapourising chambers and long inlet and outlet lines. Pressurising effect - (constant) backpressure reduces output. For example, high resistance in the line after the vapouriser will compress all gas before it. This increases the ratio of carrier molecules relative to vapour molecules in the vapour chamber, because the number of vapour molecules is fixed, whereas at higher pressures there will be more carrier gas molecules. The absolute percentage of agent per unit volume leaving the vapouriser is correct, but when the gas mixture expands post-obstruction, there are fewer molecules of agent per volume of carrier than there should be. This is a minor effect.' www.anaesthesia.med.usyd.edu.au/resources/lectures/gas_supplies_clt/vapourisers.html

Although it is difficult, I strongly recommend that one crafts one's own notes from literature, on any subject that one is passionate to learn. The journey, albeit arduous, will bring remarkable rewards in the end. No discipline seems pleasant at the time, but it will reap a bountiful harvest soon enough
