USMLE FA 2016 page 247 Abbreviation Question

Not sure if I'm allowed to post a screenshot so I won't but what does "PP" stanford in the diagram on that page?

The context is that Norepinephrine, Epinephrine, and Isopreternol all cause increased "PP" - with Isoproternol causing greatly increased "PP"

I looked in the abbreviations section at the back of the book and couldn't find it either.

Pulse pressure

 

[justadream]

Pulse pressure

Thanks!

Is there a clinical significance to this (for example, is having increased PP from taking these drugs a bad thing)?

Increased pulse pressure will make peripheral pulsations stronger maybe even felt by the patient (head nodding and all other peripheral signs of aortic regurgitation is due to increased pulse pressure).
