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
Systemic Vascular Resistance (SVR) normal values - 🧠 ANSWER ✔✔800-
1200
