What is oxygen saturation?
The amount of oxygen bound to hemoglobin in the blood.
What is a pulse oximeter?
A device attached to the earlobe that measure the oxygen saturation of arterial blood.
What does a pulse ox measure?
The amount of oxygen saturation in the blood
What is the normal measurement?
the amount of oxygen saturation in the blood
What does it mean if it is low?
there is impaired gas exchange or ventilation.
What is capillary refill?
the amount of time it take for blood to be refilled into the arterial capillaries.
What is normal cap refill for an adult client?
< 3seconds
Does it require a physician's order?
YES!
How can oxygen be delivered (name 4 ways)
non-rebreather mask, nasal cannula, venturi mask, oxygen mask, partial rebreather mask, ambu bag/intubation
A client has a NC at 2L. What if their lips are dry?
- Use KY jelly, no petroleum
What if their mucous membranes are dry?
use humidifier
What if their oxygen saturation is 88% What about if it is 98% (what are your actions as an LVN?)
- if low (88%) report to charge nurse unless COPD, get an order for O2 - Only for a short period of time
If a client is on high flow oxygen (6L) what do you need to do?
- Remove mask, clean skin and face Q2 hrs. - only for a short period of time
If someone is cyanotic, what does that imply?
Tissues do not have enough oxygen
What other VS should you do FIRST after oxygen saturation?

What is the function of Hgb? What does it carry? Where does this occur?
- Hemoglobin is iron containing oxygen transport protein in the red blood cell. - It carries oxygen and iron - It occurs in the gas exchange in the alveoli
