Dear Dr. Berg,
I am writing to you again regarding the rising PDA.
I have now enlarged the monitor values, as they were very small and hardly readable before. I have saved them in PDF format and have 2 questions regarding them.
1. Could you possibly identify a connection between the small abbreviations (m), (s)? Could \\\"manually\\\" be meant by this? (Or am I completely wrong with my layman's consideration... and what could the small (s) stand for? What abbreviation could it be?) The abbreviations (s) and (m) are always in parentheses on almost all pages.
2. How is it possible that an FIO2 (m) of 23% was used at the same time as an FIO2 (s) of 100%? (at the same time) In my opinion, the FIO2 (m) cannot be room air, as room air has 21% oxygen, right?
Kind regards
(Note: The small (m) is also present in the schema FIO2 (m).)
Hello,
First of all, regarding the data No 1 is not readable to me, and No 5 and 7 do not contain any information here, but the others are readable. As for Question 1, I have to pass, as only the person who came up with these abbreviations can know what they mean. You will have to ask the monitor manufacturer about it.
Regarding Question 2,
1. Is it room air or not? It is definitely not room air. On an anesthesia machine, you can adjust the concentration of oxygen to any value and mix it with other gases. As I mentioned before, a slightly higher concentration is often used to have a small safety margin. The values with 23% that were frequently recorded are surely the default setting of the device.
At 21:51, 22:05, and 22:20, someone probably manually pressed the O2-Flush button briefly. This sends pure oxygen = 100% O2 into the breathing system via a shortcut. (For whatever reason) At this time, other settings are likely to be automatically recorded by the system in the pdf 6 at the same times with a flow of 6, 6, and 8 l/min, as well as in protocol 6, the PEPP pressure at the times 21:51, 22:05, 22:20.
This is the explanation for the different concentrations. At 21:51, the continuous setting was probably transmitted first in the same minute, and then the flush concentration. Immediately after, the FiO2 naturally drops back to the preset level.
From the protocol, it can also be seen that at least no N20 (nitrous oxide) and also no anesthetic gas sevoflurane were used in a dosage sufficient for anesthesia.
Overall, I believe you were assisted with a mask ventilation until the high spinal anesthesia subsided. Probably, due to your weak spontaneous breathing, you were manually ventilated 3 times with 100% O2 to raise your blood oxygen level.
Is everything answered? With kind regards, R. C. Berg
