A

sinus tach, afib/flut, AV nodal reentry, accessory pathway -mediated tachycardia, atrial tachycardia, MAT, junctional tachycardia

21
Q

What is the mechanism of a PVC?

24
Q

What does monomorphic VT look like?

A

wide and bizarre QRS complexes

25
What is a Dressler beat?
p wave during monomorphic VT
26
Patient has narrow complex tachycardia, pt hemo unstable (or SVT)
synchronized cardioversion
27
regular, wide complex tachycardia, pt hemo unstable
antiarrythmic
28
CorPP (coronary perfusion pressure) calculation
= diastolic BP- right atrial pressure
29
What GCS score and RR are indicative of impending respiratory failure?
<8 or >40
30
2 categories of hypoxia?
normocapneic vs hypercapneic
31
What is a good algorithm to look up hypoxia algorithm?
Cleveland clinic algorithm
32
How to estimate FiO2 estimation of nasal cannulas?
= 21 + 3(L of O2)
33
What are EKG changes for Left atrial enlargement?
II and V1
34
How do you calculate how much fluid to give in a burn patient?
1. Parkland Formula=4mL x body weight (kg) x %TBSA, for total Liters in a 24 hour period 2. First 8 hours give half, and then divide the rest over a 16 hour period
