Conclusion.

OK let’s put it all together. What do we need to know to get the full picture in haemodynamics? The table below shows all the parameters we need, along with which can be obtained using the USCOM and the Inotropy 2009 software.

Parameter	Indicator	Shown by USCOM	Inotropy 2009
Preload	SV, SVV, FTc.	*
	LVEDVI		*
Afterload	SVR	*
	BP mean	*
Inotropy	Vpk, SV, FT,	*	*
	Inotropy, SMII	†	*
Cardiac Output	CO, CI, SV, HR	*
Oxygen Delivery	CO, SpO2, DO2	*	*
Oxygen Usage	VO2		*
Haemoglobin	Hb	†
PE:KE Ratio	PKR	†	*

It’s not hard to see why the USCOM has been called the “Swiss Army Knife” of haemodynamics!

With the simple tools outlined in the three companion booklets in this series you should be able to handle just about any haemodynamic disturbance that medicine can throw at you. What’s more, you can do it quickly, non-invasively and without any guesswork.
The days of “let’s try it and see” or “it could be anything, cardiac, pulmonary, who knows?” have gone. We can now take control of the situation and base our therapy on what we know will happen, not on what we hope will happen. Uncross your fingers and let’s do some third millennium haemodynamics instead of third rate medicine.
