Drugs Flashcards
1
Q
Oxygen indications
A
- Chest pain or SOB for any reason
- 10-15 L/min by non-rebreather mask
- Don’t mess with NC, not enough at 6 L/min max
- Positive pressure in cardiopulmonary arrest
2
Q
Oxygen indication for positive pressure in cardiopulmonary arrest
A
- Bag-valve-mask with an oropharyngeal airway (BVM with an OPA)
- Laryngeal mask airway (LMA)
- Endotrachial tube
3
Q
Epinephrine indications
A
- V-fib
- pulseless V-tach
- PEA
- asystole
4
Q
Epinephrine MOA
A
Increases:
- systemic vascular resistance
- arterial pressure
- heart rate
- contractility
- myocardial oxygen demand
- automaticity
5
Q
Epinephrine dose
A
1 mg Q 3-5 mins (IV or IO)
- No max dose
- 10 ml of 1:10,000 soln = 1 mg
- 2.5 X IV dose down ET tube
6
Q
Amiodarone indications
A
- V-fib, pulseless v-tach
- wide complex v-tach
- SVT due to WPW
7
Q
Amiodarone MOA
A
- suppresses ectopy
- increases atrial, AV and ventricular refractory periods
- antianginal effect
- slows sinus rate
- prolongs QRS and QT intervals
8
Q
Amiodarone dose
A
- 300 mg, may rebolus 150 mg in v-fib/pulseless v-tach, PSVT
- 150 mg over 10 min, may bolus once in wide complex v-tach
- drip rate 0.2-2 mg/min
9
Q
Atropine indications
A
bradycardia
10
Q
Atropine MOA
A
- parasympatholytic
- accelerates rate of SA discharge
- improves AV conduction
11
Q
Atropine dose
A
- 0.5 mg IV q 3-5 min prn
- MAX dose 3 mg
12
Q
Adenosine indications
A
- SVT
- diagnostic tool in stable VT
13
Q
Adenosine MOA
A
- slows AV conduction
- interrupts AV nodal re-entry pathway
- may worsen SVT due to WPW
- half-life is less than 10 seconds
14
Q
Adenosine dose
A
- 6 mg IV push followed by 20 cc saline flush
- may repeat at 12 mg IV in 1-2 minutes
- may repeat 12 mg dose once more
- sinus pause if effective
15
Q
Diltiazem (Cardizem) indications
A
- SVT
* *DO NOT use in WPW, AV block, with IV beta-blockers
