Hi, nicely done and illustrated. I'd like to question the use of the FS1023 flow sensor which seems to be for measuring liquid flow, not gas (air and oxygen) flow which is what they are used for here. This is a crucial part of the system as it affects tidal volume which is actually the hardest thing to control safely - which is why I think bellows are still used in many ventilators, especially as flow sensors can be prohibitevly expensive. Also, am I reading that the FS1023 sensor is not recommended for new designs?

Hi @Adrian52, thank you for bringing this to our attention. I am currently working with Renesas to update this article, as there have been updates to this ventilator solution since we published it. Will keep you posted. Thanks, Kamilla.
