Cheetah Medical has joined Baxter International Inc. (Baxter), a global medical products company. Please contact your previously established Cheetah Medical representative with questions.
We strive to help people understand and learn about different aspects of hemodynamic management such as stroke volume metrics, non-invasive monitoring for fluid responsiveness, passive leg raise fluid challenges, and the Cheetah NICOM system. You can visit our website at www.cheetah-medical.com for more information.
This is very good! However, we have used this for 3 years at our hospital. I find it very nurse user dependent. Then also, depending on the busyness of the nurse, they will need a dedicated 30 minutes, if efficient, to do this. Finally, while you can find good validation on post valve cardiac patients, and colon rectal surgical patients, it is harder to find such data, that is all concordant, on critically ill medical patients. In fact, you can find negative as well as positive studies. One, on septic patients in the ED for example, found that the 250 cc bonus protocol did not give good results, but the 500 cc did better. I believe there is an NIH study to answer this now enrolling. Finally, still look at the patients, as Cheetah would agree. A look at Annie and her neck veins would have told you that she was fluid responsive. It’s use is in those patients where we would previously have placed an arterial line and a Swan!
The video narration is VERY vague about how to interpret the data at about 14:30. The video shows a -15% result, yet the narration appears to be speaking only in terms of positive percentage. Do you mean that anything LESS THAN A 10% INCREASE FROM BASELINE suggests the patient is NOT Fluid Responsive? I'm guessing that anything BELOW a 10% INCREASE ABOVE Baseline is Not Fluid Responsive, and anything ABOVE a 10% INCREASE ABOVE BASELINE is considered Fluid Responsive? You really should re-narrate the video so that the positive or negative changes in baseline are properly explained... Why don't you simply make the data indicated on the Cheetah indicate whether or not the test suggests Fluid Responsiveness or Not?
Hi Bryan, Thank you for your questions and comments. I encourage you to go on our new website which includes updated videos that you may find more useful. Regarding your question, yes, below a 10% increase above baseline suggests the patient may not be fluid responsive and above 10% suggests the patient is likely to be fluid responsive - this is language directly from clinical studies. Apologies if you find the narration confusing, and the updated videos on the website should help with this. If you have any additional comments or questions, please contact us through our website and I am happy to set up a quick call to discuss further. Thank you.
The SVI is negative (-15) meaning the patient does not need more fluids and may be even fluid overloaded. Anything from 0-10% = not responsive to more fluids (or with barely any effect). An SVI > 10% means the patient will benefit from more fluids. If I see a negative SVI number pop up I do not give more fluids and/or recheck the test.
