3 types of SVT and describe

A

all always early
PAC- wide QRS w/ P before it

Q

PEA is

A

pulseless but not asystole, vfib, vtach

so. ..
- EMD (no wall motion)

Q

how to treat all symptomatic bradycardia

A 
atropine 0.5mg IV 
then
any of the following:
- more atropine (0.5mg) IV
- dopamine (2-20 mcg/kg/min) IV
- epi (2-10 mcg/min) IV

20
Q

cause of a huge R wave

A

LVH

21
Q

cause of lots of ST changes in many leads

A

pericarditis

22
Q

acute heart failure means

A

new onset pulmonary symptoms

23
Q

maximal rate to pace a bradycardic person

A

2x current rate (more MI or rhabdo)

24
Q

how do you know you have to increase the current when transcutaneously pacing someone

A

no heartbeat after pacer spike, no palpable pulse

electrical and mechanical capture

25
Q

cardioversion tachycardias (charge in joules)

A

narrow + reg: 50-100
wide + reg: 100
narrow + irreg: 120-200
wide + irreg: 200 (unsynch)

26
Q

treat a reg + wide tachycardia w/ pulse

A 
unstable - cardiovert 100
stable - proceed w/o cardiovert
...
is it vtach or SVT?
....
adenosine 6mg IV helps SVT only; if helps, give 12mg IV
....
if that doesn't work, you have amiodarone 150mg/10min IV (have V.tach)
27
Q

treat a reg + narrow tachy w/ pulse

A 
vagal maneuver (if stable)
shock 50-100 (if unstable)
then
adenosine 6mg IV
not working?
adenosine 12 mg IV
28
Q

adenosine IV must be followed by

A

saline flush x 2

29
Q

treat narrow, irregular tachy w/ pulse

A

CCB or BB

30
Q

treat wide, irregular tachy w/ pulse

A

amiodarone 150 mg/10 min IV

31
Q

treat wide, irreg, tachy WITHOUT pulse

A

amiodarone 300 mg PUSH followed by 150 mg PUSH

Unless is PEA or asystole

32
Q

after they become stable, what to do

A
  • mental status ok? (follow commands?)
  • breathing (ET tube needed?)
  • BP
  • 12 lead
  • CXR
  • cool (if mental status impaired)
33
Q

ideal CCF (chest compression fraction)

A

80% (60% = “adequate”)

34
Q

ideal tidal volume

A

500-600 mL (half squeeze of adult bag)

35
Q

what % of normal capnography does CPR give?

A

25-30%

36
Q

OPA how to size?

A

corner lip to angle mandible

37
Q

NPA how to size?

A

corner nare to tragus

38
Q

name advanced airways

A

supraglottic:
king, combitube, laryngotube
definitive:
ET, trachostomy

39
Q

1 of confirming and monitoring tube placement

A

capnography

40
Q

what does epi do?

A

increase MAP which increases perfusion pressure to heart

41
Q

what does amiodarone do?

A

blocks a and b stimuli

slows heart, making defibrillation more effective

42
Q

reversible causes of cardiac arrest are (6H + 5T)

A 
hypovolemia
hypoxia
hydrogen ion (acidosis)
hypokalemia
hyperkalemia
hypothermia
tension pneumo
tamponade 
toxins
thrombosis (PE)
thrombosis (coronary)
43
Q

PETCO2

A

10

44
Q

diastolic pressure

A

20

45
Q

Joules for a monophase defib

A

360

46
Q

Joules for a biphasic defib

A

120-200 (do what manufacturer says)

47
Q

Epi dose for cardiac arrest

A

1 mg/4 min

48
Q

Amiodarone dose for cardiac arrest

A

300 mg bolus
followed by
150 mg bolus

49
Q

Treat cardiac arrest

A 
CPR 2 rounds, 2 shocks
epi 1mg @ 4 min
amiodarone 300mg @ 6 min
epi 1 mg @ 8 min
amiodarone 150 mg @ 10 min
