I am so happy I came across this video! I'm going to set up one of your ghetto test lungs because your demo of PEEP is such a great way visualize it for the students!
It'd be nice if these things could do weaning parameters. And I don't mean their SBT ability in the internal menus. I'm talking about NIF, and Vital Capacity. These things argood though.
@@hbomb1512 I was told that it was essentially a 1 way circuit at that point, the filter needing to be on the patient side so contamination doesn't get exhaled out the exhalation side. Perhaps I had been told wrong.
@@jasonkeef600 the filter is designed to prevent cross contamination between the machine and patient. The LTV has an exhalation limb that doesn't seem to be filtered. I do know that the manufacturer doesn't approve the filter to be placed at anywhere other than than at the machine and distal to the patient. If you were taught otherwise, I guess it couldn't hurt, it actually makes a lot of sense! Just know that the filter is designed to act as barrier between the machine and patient for possible back pressure contamination and is not medically approved to filter the exhaled air that escapes from the expiratory limb. There are actually some studies that say that the bacterial filter doesn't really decrease incidents of infection, so it seems to just be a CYA/money maker thing from the manufacturer. I am no infection control expert; I would adhere to your protocols and company guidelines for use. Great question! I'll look more in this, you have me curious now!
