25
What happens if the non-rebreather mask does not function properly?
CO2 buildup, the pt can't breathe room air
26
What are 5 types of high-flow O2 devices?
- Venturi mask - Face tent - Aerosol mask - Tracheostomy collar - T-piece
27
Venturi mask: | Used for _____ O2 delivery.
precise
28
Venturi mask: | The best for ____ ____ ____.
chronic lung disease
29
T-piece: | Delivers desired FiO2 for what type of pts?
those with tracheostomy, laryngectomy, ET tubes
30
T-piece: | If we see mist during inspiration or expiration, what should we do?
Nothing! This is what you want to happen.
31
2 Types of noninvasive positive-pressure ventilation (NPPV):
- BiPAP | - CPAP
32
How do NPPV systems deliver oxygen?
uses positive pressure to keep alveoli open
33
CPAP: | When does it deliver the set positive airway pressure?
Throughout the breathing cycle...during both inhalation and exhalation
34
CPAP: | Opens collapsed _____.
alveoli
35
CPAP: | When is it used?
- atelectasis after surgery - cardiac-induced pulmonary edema - sleep apnea
36
T/F: Transtacheal Oxygen Delivery (TTO) is used for LONG-term delivery of O2 directly into the lungs.
True
37
TTO: | What is the benefit?
- avoids irritation that can be caused by nasal prongs | - more comfortable
38
3 types of O2 "tanks" for home use:
- compressed gas in tank - liquid O2 in reservoir - O2 concentrator
39
How do we reposition patient to open the airway?
- head tilt-chin lift (normal) | - jaw thrust method (spinal injury)
40
How do we clear the airway?
suction
41
What is the rate when using a bag-mask-valve (BMV)?
8 - 12 squeezes per min
42
Who can we use an oropharyngeal airway on? Why?
Only for unconcious/semiconcious pts | will stimulate gag reflex
43
How do we place an oropharyngeal airway?
- Place along the outside of the jaw with one end of the airway at the bottom tip of the ear - Close mouth and bring tip of the airway toward the corner of the mouth
44
Proper placement of the oropharyngeal airway:
tip of the airway lies above the epiglottis at the base of the tongue
45
Why is it important to use the correct size oropharyngeal airway?
can cause airway obstruction
46
What do we do before placing a nasopharyngeal airway?
- LUBRICATE! | - Hold the airway against the side of the face and ensure it extends from the tip of the nose to the earlobe
47
Proper placement of the nasopharyngeal airway:
the tip of the airway lies above the epiglottis at the base of the tongue
48
Short-term airway: ___ or ___ | Long-term airway: ____ (how long?)
Short-term: oral or nasal | Long-term: tracheotomy (for greater than 21 days)
49
3 ways to check for correct ETT placement:
- auscultate - inspect chest expansion - end-tidal CO2 detector
50
Where do you auscultate first when checking ETT placement?
epigastric area
51
What test is used to validate the depth of the ETT?
CXR
52
What is correct placement of ETT?
3-4 cm above carina
53
What 6 things do you assess with ETT?
1) tube TYPE 2) SIZE of airway 3) LOCATION at teeth/gums 4) pilot BALLOON 5) check for mucosal DAMAGE 6) check for STABILITY
54
If ETT balloon pressure is too high: | If too low:
Too high = tracheal damage | Too low = aspiration around cuff leak
55
What tool is used to measure cuff pressure?
aneroid pressure manometer
56
Why do we suction ETT?
maintains patent airway, promotes gas exchange
57
Where is the HOB when suctioning?
elevated
58
How long should we suction each time?
10-15 sec
59
5 complications of suctioning:
1) hypoxia 2) tissue (mucosal) trauma 3) infection 4) vagal stimulation, bronchospasm 5) cardiac dysrhythmias
60
What should we do if vagal stimulation occurs during suctioning? How do we know when it happens?
back off quickly | slows down heartrate
61
What cardiac dysrhythmia can occur from induced hypoxia during ETT?
PVCs from lack of oxygen
