Q

CVP Monitoring: V wave

Study These Flashcards
A

Venous return against a closed tricuspid valve

20
Q

Normal ICP

21
Q

Preferred drug to treat brain swelling: and dose:

Study These Flashcards
A

Mannitol 0.25-1 g/kg

22
Q

Hyperventilation affect on cerebral vessels/blood flow

Study These Flashcards
A
  • Constriction of cerebral blood vessels
  • decreases cerebral blood flow
  • decreases ICP
23
Q

Noninvasive ways to decrease ICP

Study These Flashcards
A
  • maintain normoglycemia
  • maintain normothermia
  • suction ONLY when indicated
  • sedation
24
Q

Normal cerebral perfusion pressure (CPP)

Calculation?

Study These Flashcards
A

CPP= MAP-ICP

50-150 mm Hg

25
Cushing's triad
Hypertension Bradycardia Irregular respirations
26
Syndrome of inappropriate antidiuretic hormone (SIADH)?
Excessive reabsorption of water due to increased production of ADH
27
Common causes of SIADH
Carcinoma of the lungs | Various head problems
28
Roles of CRNA: pre-op
interview pt establish rapport review labs/medication Determine type of anesthesia to deliver
29
Roles of a CRNA: peri-op
Preform safe induction Maintain anesthesia Safe emergence Meticulous scrutiny of pt and monitors
30
Roles of CRNA: post-op
Adequate pain control | Monitor for post-op complications
31
Alpha 1 & 2
A1 stimulation leads to constriction of vascular smooth muscle therefore ⬆️ PVD A2 stimulation inhibits norepinephrine
32
Beta 1 & 2
B1 stimulation ⬆️ heart rate, conduction velocity & contractility. B2 stimulation relaxes vascular smooth muscle, skeletal muscle, and bronchial smooth muscle.
33
Levophed
Alpha adrenergic affects and beta stimulation. Intensely contracts vascular .... including kidneys. Increases PVR.
34
Propofol
Sedation not a pain reliever, it relaxes smooth muscles and can ⬇️ CO, contains disodium odetate to help retard microbial growth
35
Cerebral perfusion pressure (CPP)
CPP= MAP - ICP
36
Transducer level for ICP
Foreman of Monroe (top of ear and outer of eye)
37
Transducer level for A-Line
3rd intercostal space, mid axillary line on phlebostatic axis
38
Heart sounds with papillary rupture: right ventricle
Rupture of right ventricular pap muscle you get tricuspid regurgitate
39
Heart sounds with papillary rupture: left ventricle
Mitral regurgitate. | if complete transaction occurs you get mitral regurgitate not compatible with life
40
ST elevation in leads: V1, V2, V3, V4
Coronary: LAD | Part of heart: anterior/septal wall
41
ST elevation in leads: 1, avL, V5, V6
Coronary: Circumflex | Part of heart: lateral wall
42
ST elevation in leads: II, III, avF
Coronary: right coronary | Part of heart: inferior wall
43
ST elevation in leads: V1, V2
Coronary: right | Part of heart: posterior wall
44
ST elevation in leads: V3R, V4R, V5R, V6R
Coronary: right | Part of heart: right ventricular wall
45
SAo2 vs PAo2
SAo2- percentage of hemoglobin molecules that are bound to oxygen molecules in the blood. PAo2- measures O2 in the blood
