Paired
31

Paired
32
The Larynx extends from:
C3-C6
33
Which type of administration will provide the fastest onset of Succinylcholine if IV access is not available?
Submental administration
34
What is the only NMB that can be given IM?
Rocuronium
35
Which gas law applicable to respiration?
Boyle’s law
36
Which muscle increases the anterior-posterior diameter of the chest?
External intercostals
37
Is expiration active or passive?
Passive (usually)
38
What muscles are involved in active expiration? (4)
Abdominis muscles (rectus admoninis and transversus abdominis) Oblique muscles (external and internal) *total of 4
39
How many muscles are used in active expiration?
4
40
Accessory muscles that aid in inspiration
Sternocleidomastoid Scalene muscles
41
2 main muscles for inspiration:
1. Diaphragm 2. External intercostals
42
Contraction of inspiratory muscles (reduces/increases) thoracic pressures and (reduces/increases) thoracic volume
REDUCES thoracic pressure INCREASES thoracic volume
43
What is the amount of air in a single breath X the number of breaths per minute? TV X RR
Minute ventilation
44
What measures the fraction of minute ventilation that is available for gas exchange?
Alveolar ventilation
45
= (TV - anatomic dead space)XRR What is this equation for?
Alveolar ventilation
46
Is Alveolar ventilation (VA) directly or indirectly proportional to CO2 production?
DIRECTLY
47
Is Alveolar Ventilation directly or indirectly proportional to PaCO2?
INDIRECTLY
48
What are the 4 types of dead space?
1. Anatomic 2. Alveolar 3. Physiologic 4. Apparatus
49
This dead space is defined as air confined to the conducting airway
Anatomic
50
This dead space is defined as alveoli that are ventilated but not perfused
Alveolar dead space
51
This dead space is defined as anatomic dead space + alveolar dead space
Physiologic dead space
52
This dead space is defined as dead space added by equipment
Apparatus dead space
53
How many mL/kg Vital Capacity is required for an effective cough?
15 mL/kg
54
What are the 3 zones of the lung (not West’s)
Conducting Transitional Respiratory
55
If TPP is positive, does the airway stay open or closed?
Open
56
Pressure outside of the airway is called
Pleural pressure
57
Pressure inside the airway is called
Alveolar pressure
58
How much is the normal dead space in a 70 kg adult?
2 mL/kg or 150 mL
59
Does atropine increase or decrease anatomic dead space?
Increase *bronchodilator = increases the volume of the conducting zone
60
3 factors that increase Vd/Vt ratio
Face mask Atropine Neck extension
61
Factors that decrease the ratio of Vd to Vt
ETT LMA neck flexion
62
Which equation can be used to calculate physiologic dead space?
Bohr equation Vd/Vt = (PaCO2 - PeCO2)/PaCO2
63
The best ventilated alveoli are the most
Compliant
64
V/Q ratio represents
Ventilation to perfusion
65
Normal minute ventilation
4 L/min
66
Normal cardiac output
5 L/min
67
Normal VQ ratio
0.8
68
V/Q mismatch: When the number is greater that 0.8, this moves toward
dead space
69
V/Q mismatch: When the number is smaller than 0.8, this moves toward
Shunt
