Anyone use this? HR/Systolic BP... its a good indicator left ventricular dysfunction is you suspect such. Higher numbers are worse.

I've never seen it used nor have I ever used it. But it does seem interesting.

Overview :
The Shock Index (SI) is the ratio of the heart rate to systolic blood pressure. The index is a sensitive indicator of left ventricular dysfunction and can become elevated following a reduction in left ventricular stroke work. It can be used in the Emergency Department and Intensive Care Unit to identify patients needing a higher level of care despite vital signs that may not appear strikingly abnormal.

It makes sense to me. If the pulse is increasing and the blood pressure is decreasing, you would expect outcomes to be worsening.
However, I think this can indicate a lot of things beside left ventricular failure. For instance, hypovolemic shock would result in a compensatory increase in heart rate, and perhaps a decrease in blood pressure if the system couldn't keep up with losses. So, I'm not sure the "shock index" will work for pre-hospital providers.
I'd be interested to hear from some people in hospital ICU/CC settings about whether or not this is used and what they think of it.
