CDI continuous blood gas monitor

None of the CGMs in the market are FDA approved for in- patient.  Vendors are marketing them to pre- discharge patient so they can monitor their glucose levels while at home. 

I would say, none is approved for cardiopulmonary bypass.

The CGM measures are interstitial glucose, not arterial, venous or capillary so the levels are different from venous, arterial or capillary levels even when taken at the same time.   They have a small filament that is injected into the back of the  upper arm ( or abdominal area).  They are only good for 14 days and have to be replaced. 

They are expensive.  They run around $ 1200 to 2000 each.  The results can be sent to doctors office using a device that takes glucose ready usually every 5-15 minutes depending on the program. It is convenient  and is probably the future but has to be affordable.  Some insurance companies do not pay for it.  

Hi Pet,

     I believe she is referring to the instrument by Terumo, not a continuous glucose monitor.

I came across this once before by accident but have not researched it to know whether it is FDA approved or not. By the brochure, they are marketing it for open hearts, fits on the bypass machine, has cartridges to hook into it somehow, has little gas canisters for calibration, etc. Looks like it could be 'cool' but also like a lot of parts.

Just my 'at a glance' 2 cents.

Yes, the Terumo blood gas monitor. I thought it sounded familiar so I reached out to the ECMO coordinator. They use it post oxygenator - it's truly only a monitoring device. They calibrate it to a blood gas analyzer 2 or 3 times a day and then it just gives them a constant visual so see if there's a sudden change and then they check with a gas.

It was perfusion that had asked about it and then I get a little nervous. I want them to understand that it's not an actual instrument - it's just a tool.

Thanks, Danyel for that additional information. Very interesting. Luckily my perfusionists have never mentioned it.

Thanks to you also, Pet. I had briefly looked into the CGMs for use in OR at one point but I don't remember noting that they were not approved for use in hospital. I learn something new everyday!
