Guaranteed pass
Normal Length for PR, QRS, and QT intervals. - ANSWER PR 0.12-0.20 sec, QRS 0.08-0.12 sec,
and QT interval less than or = to 450 ms or half the R-R interval
Big box on ECG readings = ___ seconds? - ANSWER 0.20 seconds
Little boxes on ECG readings = ____ seconds? - ANSWER 0.04 seconds
The mA that achieves capture is the _______ _________ - ANSWER pacing threshold
Defibrillation energy settings (biphasic and monophasic) - ANSWER biphasic 120-200 j and
monophasic 360 j
Synchronized Cardioversion energy settings for SVT or aflutter, for afib, and for monomorphic VT
(biphasic and monophasic) - ANSWER SVT or aflutter-biphasic 50-100 j & monophasic 200 j
Afib-biphasic 120-200 j & monophasic 200 j
Monomorphic VT-biphasic 100 j & monophasic 100 j
Vtach treatment - ANSWER Synchronized cardioversion and Antiarrhythmic such as Amiodarone
(150-300 mg) and/or lidocaine
Vfib treatment - ANSWER Defibrillation also can load them up with Amiodarone
, SVT treatment - ANSWER Vasovagal maneuvers, carotid massage, Adenosine (if BP is good) 6 mg
for first dose and then 12 mg for the second dose, or synchronized cardioversion
Torsades treatment - ANSWER Synchronized cardioverison (if regular) or defibrillation (if
irregular) and administer Mg (treating underlying cause)
Anatomical location of Cardiac Assessment Landmarks - ANSWER
Pulse pressure calculation - ANSWER Difference between the systolic and diastolic pressure for
example 120/60 the pulse pressure is 60!
Cardiac output normal values - ANSWER 4-8 Liters per minute (formula is Stroke Volume x Heart
Rate)
Cardiac Index normal values - ANSWER 2.5-4 L/min/m2 (formula is Cardiac output divided by
Body Surface Area aka need ht and wt)
Central Venous Pressure or Right Atrial Pressure normal values - ANSWER 2-6 mmHg or 2-8 cm
H2O
Pulmonary Arterial Pressure (PAP) normal values - ANSWER Pulmonary Artery Systolic (PAS) 15-
30 mmHg
Pulmonary Artery Diastolic (PAD) 5-15 mmHg
Pulmonary Artery Mean (PAM) 9-18 mmHg
Pulmonary Artery Occlusion Pressure (PAOP) AKA Wedge normal values - ANSWER Similar to
CVP or RAP and the diastolic pulmonary artery pressure will reflect this value closely... PAOP 6-
12 mmHg
