Oxygen Gradients/Oxygenation Flashcards
(20 cards)
how much oxygen (in percentage/liters) is approximately in room air?
around 21%
when do start with the humidification of oxygen?
around the given amount of 4 LPM
what is the cutoff of using a regular flowing NC?
cutoff ends at 6 LPM; have to use a HIGH FLOW NC
when do we use a HIGH FLOW NC?
utilized between 7-10 LPM
- can also have a switch onto a oxygen mask
when do we use a NONREBREATHER MASK?
given at highest levels of 15 LPM; no humidification
when do we use VENTURI MASKS?
these have precise controls of oxygen
- based on valve color; can range from 2 LPM - 15 LPM
1 LPM
24% effective FiO2
2 LPM
28% effective FiO2
3 LPM
32% FiO2
4 LPM
36% LPM
5 LPM
40% effective FiO2
6 LPM
44% effective FiO2
7 LPM
48% effective FiO2
8 LPM
52% effective FiO2
9 LPM
56% effective FiO2
10 LPM
60% effective FiO2
hypoxia
inadequate tissue oxygenation at the cellular level
incentive spirometry
type of hand held plastic device
- taking a deep breath and helps to expand the lungs–want to target around 1000 mL
- important to do routinely to prevent infections, improve breathing, and help COPD symptoms
what is important to consider in regards to OXYGEN DELIVERY?
- making sure if possible to use the lowest setting possible
- have enough oxygen during transportation
- oxygen is COMBUSTIBLE – no smoking or open flames
- allow for extension tubing when patient must be mobile
what to consider regarding COPD patients?
chronic obstructive pulmonary disease;
having LOW OXYGEN is the pt’s regular STIMULUS; very typical to see levels around 88% - 92%
- want to keep oxygen levels neutral; do not want pt to become more OXYGEN DEPENDENT
- typically for a normal patient having a HIGH CO2 level is considered our stimulus
