1
Q

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

A

1.34 mL

2
Q

Fick Equation

A

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

3
Q

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

A

Days to weeks

4
Q

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

A

It can’t get into the erythrocytes!

5
Q

Carbon monoxide affects ____ first

A

Carbon monoxide affects the heart first

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

6
Q

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

A

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

7
Q

CO effects on hemoglobin

A

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

8
Q

Symptoms of CO poisoning

A

Headache

Tightness across forehead

Irritability

Dizziness

9
Q

Treatment for CO poisoning

A

Hyperbaric 100% oxygen and removal of the CO source.
