respiratory rate (vital signs analysis)

what is tachypnea

when the rate of breathing is too fast, over 20 at resting

rate of breathing is not about…

how much oxygenation you have but how acidic yoru blood is

more breathing =

less acid in the blood stream because you are getting rid of co2

increased metabolic demands…

increase acidity because body is working harder producing more co2 and acids

decreased ventilation..

increases acidity because you are not getting rid of as much co2

what are some other causes of acidity

DKA, lactic acidosis and kidney malfunction

Blood acidity and respiratory rate are closely related because

your lungs control how much CO₂ you keep or get rid of.

what system increases acidity

Sympathetic nervous system

sympathetic nervous system activation increases acidity because it is

early signs of shock, and things like anxiety, panic attacks, and extreme pain which can all increase your respiratory rates

low o2 in the blood stream is

hypoxemia

hypoxemia helps…

make respiratory rate speed up

bradypnea

respiratory rate goes down and slowes

why does respiration rate slow down

because of decreases acidity in blood stream, meds, and neurological injury

decreased acidity in bloodstream =

alkalosis

what kinda meds decrease respiratory rate

sedatives, opiates

what kinda neurological injuries slow down respiratory rates

increased ICP (intracranial pressure)

the more acid in your blood

the higher your respiration rate is
