oxyhemoglobin dissociation curve

how many oxygen can hemoglobin hold?

four

what makes oxygen bind to hemoglobin?

iron

what does PaO2 mean?

pressure of oxygen dissolved in your arterial blood not bound to hemoglobin

what does the oxyhemoglobin dissociation curve show?

how much oxygen is bound to HEMOGLOBIN at difference oxygen levels in the blood

what is SaO2?

basically like SpO2, its the saturation

oxygen in your blank will be 100% due to

lungs, its a high concentrated space for oxygen. hemoglobin wants to grab all of the oxygen in order to transport it to the rest of the body

oxygen in your blank will be lower like 25%-50% due to

tissues like your feet or toes this is because hemoglobin has dropped of oxygen to other placed before it got to the further place

who wants to hold onto oxygen?

left shift, O2 Latches on

who wants to give up oxygen?

right shift , O2 is Released

signs and symptoms for RIGHT shift

decreased affinity for hemoglobin so you would see everything is Raised (think Raised and Right)

-Raised temperature

-CO2 is Raised

-Hydrogen is Raised causing pH to drop

signs and symptoms for a LEFT shift

increased affinity for hemoglobin so you would see everything is Lower (think Lower and Left)

-Lower temperature

-CO2 is Lower

-Hydrogen is Lower causing pH to raise

oxygen is primarily transported through the body in blank attached to blank molecules

red blood cells, hemoglobin

hemoglobin carries blank of the oxygen in blood

98%

for every blank molecule, there is a what attached to it

iron, oxygen

hemoglobin exist in two states. what are they?

t state and r state

what is the T state?

deoxygenated tense, unbound

what is the r state?

oxygenated-relaxed

with a right shift, are you more affinity or less affinity?

less affinity

with a left shift, are you more affinity or less affinity?

more

what does hydrogen ions do?

reduce the affinity of binding sites for oxygen molecules

when carbon dioxide enters the RBC, what does it do?

quickly converts to carbonic acid which then immediately goes to bicarbonate and hydrogen ions

how does temperature affect the curve?

oxygen unloading/getting rid of is favored at higher temps. meaning it’s a R shift
