I am thinking it is because this patient is compensating for something, but the BP is throwing me off. His pulses were regularly irregular. No, this isn't some test question, I am just having a hard time understanding homeostasis.

Those would be normal numbers in a small child, and with the irregularly irregular rate are what one would expect in an older person with atrial fibrillation. Atrial kick actually accounts for only a small amount of cardiac output, so the compensatory mechanisms to keep a normal pressure aren't a big trick. People tend to maintain normal blood pressure for a long time. It won't make a notable drop until you've lost one heck of a lot of output. It's amazing to see, but folks can lose a quarter of their blood volume and not drop their pressure a whit.

the heart can pump more or less blood through the body by either modifying heart rate or stroke volume, which is the vol. of blood the heart puts out with each heart beat. in the case you mentioned, the respiratory rate and BP is normal, but the heart rate is pretty high for the other 2 values. this might mean that the heart is just beating really fast without putting out too much vol/stroke or oxygen for that matter bc of the low resp. rate. this would probably happen from panicking or something like that. actually im not even sure what conditions would cause this

I get an irregular heartbeat and a feeling of uh-oh this might be a heart attack. My heart will actually skip a couple beats. Pulse gets kind of thready sometimes. And I figured out the same thing as the writer above me. MSG.
Glad to know I am not alone. Thank You

I dunno, but one time I spent 9 hours in the hospital because my pulse was 122, resp 20, and BP 100/65 (which is high for me). I had blood gases taken (they wanted to see if I was having a stroke).
It happened again another time, and I figured out that whenever I eat MSG, I react with rapid pulse. So now I avoid MSG.

Paroxysmal tachycardia is a condition of unknown etiology. This can cause tachycardia while respiratory rate and BP are normal. It can also be caused by extra focus in myocardium. It can also becaused by tobacco abuse. Treatment depends upon cause. Idiopathic one is treated by carotid sinus massage and beta blockers.
