Shock/Ischemia/CPR Flashcards
Regarding CPR, how does survival in anesthetized patients compare to overall survival?
47% vs. 4-9.6%
From RECOVER, due to decay of skills, refresher training is recommended every?
6 months
T/F: veterinarians or technicians may be considered leaders of a CPR team
TRUE
From RECOVER, recommended chest compression depth:
1/3 to 1/2 the width of the chest
From RECOVER, in large and giant breed dogs, hands should be placed…
over the widest portion of the chest
From RECOVER, in keel-chested dogs, hands should be placed…
directly over the heart
From RECOVER, in barrel-chested dogs, you should consider chest compression in which position?
dorsal recumbency with sternal chest compressions
From RECOVER, recommended chest compression rate
100-120 compressions/min
From RECOVER, in nonintubated patients or single-rescuer CPR, what C:V ratio is recommended?
30:2
From RECOVER, recommended ventilation rate and tidal volume?
10 bpm and 10 ml/kg
From RECOVER, CPR should be performed in cycles of how many minutes?
2
From RECOVER, what is the low dose of epi? High dose? How often?
0.01 mg/kg (low), 0.1 mg/kg (high), and q 3-5min
From RECOVER, dose of vasopressin? How often?
0.8 U/kg q3-5min
From RECOVER, dose of external defibrillation with monophasic vs biphasic?
4-6 J/kg (mono), 2-4 J/kg (bi)
From RECOVER, immediate defibrillation is recommended in cases of CPA due to VF of duration of how many minutes or less?
4 minutes or less
From RECOVER, T/F: immediate defibrillation may be considered if VF is diagnosed during a rhythm check b/w cycles of CPR
TRUE
From RECOVER, T/F: 2-minute cycle of CPR should PREcede defibrillation in cases of CPA due to VF of known or suspected duration of greater than 4 minutes.
TRUE
From RECOVER, which drug can be considered in cases of pulseless VT/VF resistant to defibrillation?
amiodarone
From RECOVER, what class is amiodarone? (Vaughan Williams classification)
Class III
From RECOVER, what is the MOA of amiodarone?
Classified as class III (potassium channel blocker), but also has Class I, II, and IV activity!
From RECOVER, what is the SECOND choice drug for pulseless VT/VF resistant to defibrillation?
Lidocaine
MgSO4 may be considered for which arrhythmia?
Torsades de pointes
MOA of impedance threshold device?
more negative intrathoracic pressure = more venous return = more cardiac output
ITD not recommended in patients weighing less than? Why?
10kg. Cannot generate cracking pressure (-12 mmHg)
