hemodynamics - the future, what now?
DESCRIPTION
Optimising hemodynamics saves lives. That’s why we all spend so much time trying to do it! We measure blood pressure, heart rate and SpO2 on anything that moves... But there is a big problem with this – We are actually just trying to guess what is really going on from very limited dataTRANSCRIPT

Optimising haemodynamics saves lives.
That’s why we all spend so much time trying to do it!
We measure blood pressure, heart rate and SpO2 on anything that moves...
But there is a big problem with this – We are actually just trying to guess what is
really going on from very limited data...
But none of this tells us DO2 or VO2
“It is impossible to draw conclusions from incomplete
data doctor.”
At the 6th PICC we promised
1)That we would publish the method for rapid bedside measurement of inotropy.
2) That we would build the Smith-Madigan Inotropy Index in to the USCOM for everyone to use.
3) That we would publish the results of the BUSH protocol in septic shock study.

The Ultimate Diagnostic Device –
The Tricorder
OK, so we’re not at the tricorder stage
BUT…
Using the USCOM 1A with SMII and the
BUSH Protocol for the treatment of
septic shock
resulted in…

What next?
We have to do something similar in paediatric sepsis!!!
We need people to joın us ın a multı-centre RCT...
But it’s too hard to
learn the USCOM!
Its haemodynamics Jim,
but not as we know it!
ThisUSCOM is
astonishing, Bones!!
Echocardiography is for a few expert users
USCOM is for everybody – Learn it in a week,
use it for life!!
