So let's wrap up this video. I know
we threw a lot of numbers at you.
Keep in mind, sit down with
your handout and your notes,
look at some patient's CBC
results, and you will be amazed
at what you can learn about
what's going on with that patient.
Because, remember, the red blood cell count,
hemoglobin, and hematocrit
each measure certain aspects
of the red blood cells.
Low red blood cell is anemia.
High red blood cell is erythrocytosis
Each red blood cell carries
4 oxygen molecules.
A hematocrit rate is also known
as a packed cell volume,
is a measurement of the percentage
of the total volume.
Keep in mind the hydration status
has a significant impact
on the hematocrit and hemoglobin.
That means don't panic if your
patient was really dehydrated,
you gave them IV fluids, and their -- boom!
It looked like their hematocrit
and hemoglobin tanked.
It really didn't.
Because remember, hydration
status has significant impact
on hematocrit and hemoglobin.
Now, your patients will be able to adapt
to chronic causes of low red blood cells
much more effectively than acute and large
red blood cell loss, like hemorrhage.
MCV, MCH, and MCHC
are calculated with formulas
using the red blood cell,
hemoglobin, and hematocrit.
And they really are helpful
in determining more
detailed diagnosis and causes
of abnormal red blood cell counts.
