Flashcards in Class Information Deck (9)
1

How many mL of oxygen may be bound to one gram of normal Hb?

1.34 mL

2

Fick Equation

O2 unloaded (mL/dL) = Flow x Hb CONCENTRATION (g/dL)*1.34 mL O2/g x (Asat - Vsat)

3

How long does it take to make new erythrocytes in response to EPO?

Days to weeks

4

Why is administering 2,3-BPG IV no good?

It can't get into the erythrocytes!

5

Carbon monoxide affects ____ first

Carbon monoxide affects the heart first

 

Because it extracts a larger portion of available oxygen from its blood supply

6

Why can't carbon monoxide be picked up by a pulse oximeter?

It produces a very similar change in absorptive wavelength when bound to hemoglobin.

7

CO effects on hemoglobin

CO causes a left shift which decreases the ability of Hb to release its oxygen

8

Symptoms of CO poisoning

Headache

Tightness across forehead

Irritability

Dizziness

9

Treatment for CO poisoning

Hyperbaric 100% oxygen and removal of the CO source.
