Q

alpha 1,2

A

blood vessels, vasoconstriction

24
Q

B1

A

myocardium, inotropy and chronotropy

25
B2
blood vessels, vasodilation
26
D1
renal vasodilation
27
V1
vasculature, vasoconstrict
28
NE
alpha 1, beta 1 | vasoconstrict, increase CO, contractility
29
Phenylephrine
alpha 1
30
Epinephrine
low dose B1 | high dose alpha 1
31
Dopamine
low dose D1 Medium B1 High dose alpha 1
32
Vasopressin
V1
33
Dobutamine
B1 (some B2) | cardiogenic shock w/ HTN
34
Milrinone
PDE III Inhibitor | increased Co, , contractility
35
Inspiratory stridor- location
above vocal cords
36
ARDS definition
onset w/in 1 week of insult bilateral opacities not related to pulmonary edema or cardiac cause Po2/Fio2 <300 on at least 5cm PEEP
37
TV in ARDS
~6ml/kg | prevent volutrauma
38
Full Expansion on CXR
9-10 posterior ribs | 6-7 anterior ribs
39
Diagphrams on Lateral CXR
right over left
40
Size of pulmonary nodule (definition)
less than 3 cm
41
Nodular Pattern on CXR
- small discrete rounded opacities | - interstitial lung disease
42
Air Space Disease on Imaging, ddx includes 5 categories
``` water/pulm edema pus blood cells (lymphoma) lipoproteins (pulmonary alveolar proteinosis) ```
43
Structures of Anterior Mediastinum
teratoma thymoma retrosternal thyroid lymphoma
44
IPAP
inspiration pressure | ventilation
45
EPAP
expiration | oxygenation
46
AC Mode
- set volume and backup rate | - pressure is variable and related to compliance
47
Compliance =
change in volume / change in pressure
48
Pressure Control Mode
Select pressure | - TV, rate are variable, volume dependent on compliance
49
PEEP and venous return
PEEP increases intrathoracic pressure which increases R atrium pressure blood flows to heart due to gradient between which is decreased when you have increased R atrium pressure --> decrease in Cardiac Output
50
Peak Pressure
when there is airflow/airflow resistance
51
What causes high peak pressures
bronchospasms, secretions, ETT occlusion/plugging, mucuous plugging
52
Plateau Pressure
pressure when airflow stops/lung compliance
53
Cardiac Output =
HR x SV
54
Mixed Venous Oxygen Saturation
75-85 "oxygen left over" oxygen bound to Hgb returning to heart
55
Paraprotein Gap
Total protein - albumin | >4 significant
