CALCIUM CHANNEL BLOCKERS
Calcium channel blockers are like valium for your heart. Calms the
heart down. Indicators – tachycardia, tacharythmias
Negative intropic, chronotropic, dromotropic (relax your heart, calm it
down)
They treat – A (antihypertensives), AA (antianginal), AAA (anti-atrial
arythmia) they treat atrial dysrhythmias and supraventricular
contractions (SVT)
Names – majority end in -dipine (amlodipine, nifedipine) & verapamil,
cardizem (can be given as a continuous IV drip)
Side effects – headache & HYPOtension (take BP before administering,
hold if systolic is <100)
CARDIAC ARRYTHMIAS
QRS refers to – Ventricular
P refers to – Atrial
ATRIAL FLUTTER
Rapid P wave repolarizations in a saw tooth pattern

ATRIAL FIBRILLATION
chaotic QRS depolarizations, heart rate is irregular
TX: HEPARIN first, then ABCD
VENTRICULAR FIBRILLATION
Chaotic QRS depolarizations
TX: defibrillation (shock them)
VENTRICULAR TACHYCARDIA
Wide bizarre QRS’s
TX: Lidocaine & amiodarone

ASYSTOLE
a lack of QRS repolarizations
TX: epinehphrine & atropine
PVC
Periodic wide, bizarre QRS’S. If there are more than 6 PVCs in a minute, or 6
in a row, you elevate the priority to moderate. PVC are not priority. NOT
necessary to contact HCP.
TX: lidocaine & amiodorone
LETHAL ARRYTHMIAS
Asystole
Ventricular fibrillation
POTENTIALLY LIFE THREATENING
Ventricular tachycardia (have a cardiac output, pulse)
Atrial fibrillation
Atrial flutter
PVC

HOW DO YOU TREAT SUPRAVENTRICULAR (ATRIAL) ARRYTHMIAS?
Adenocard (adenosine – push in less than 8 seconds, fast and don’t worry
about asystole)
Beta blockers (-lol)
Calcium channel blocker
Digitalis (lanoxin, digoxin)
CHEST TUBES
Purpose re-establish negative pressure in the pleural space
(negative is good in pleural space, makes things stick together)
In a pneumothorax, chest tube removes air
In a hemothorax, chest tube removes blood
You have a patient with a chest tube in for a hemothorax, what would you
report to HCP?
1. Chest tube is not bubbling
2. Chest tube drained 800 mL in first 10 hours
3. Chest tube is not draining (because it is not doing what it is supposed
to do)
4. Chest tube is intermittently bubbling
LOCATION OF CHEST TUBES
Apical chest tube way up high, removes air because air rises (A for
Apical)
Basilar chest tube bottom of the lungs, removes blood (B for Blood)
WHAT DO YOU DO IF A WATER SEAL BREAKS?
1. Clamp it (FIRST)
2. Cut broken device off of tube
3. Put the end of the tube in NS
4. Unclamp it (because you’ve reestablished the water seal)

BEST thing to
do is put in

WHAT DO YOU DO IF CHEST TUBE COMES OUT?
1. Cover hole with a gloved hand (FIRST)
2. Put on a Vaseline gauze dressing (BEST)
3. Put on sterile dressing and then tape on 3 sides.
BUBBLING IN CHEST TUBES GOOD OR BAD?
Where? Water seal INTERMITTENTLY (good, document it)
Where? Water seal CONTINUOSLY (bad, theres a leak in the system,
find it and put tape over till it stops leaking)
Where? Suction control chamber INTERMITTENT (bad, suction is not
high enough, too low, turn it up on the wall till its continuous)
Straight catheter is to a foley cather Like a thoracentesis is to a chest
tube
RULES TO CLAMPING TUBES
Never allowed to clamp tube for longer than 15 seconds without a
doctors orders.
Use rubber tipped double clamps (because it wont pierce the tube)
CONGENITAL HEART DEFECTS
TRouBLe or not
Trouble defect is right to left shunt (blue, cyanotic)
No trouble defect is left to right (pink, acyanotic)
How do you know which heart defects are trouble? If it starts with a T
it is trouble.
WHAT DO ALL KIDS WITH CONGENITAL HEART DEFECTS HAVE?
Murmur (because of shunting blood)
They have an echocardiogram done
FOUR DEFECTS OF TETROLOGY OF FALLOT?
VarieD PictureS Of A RancH
1. Ventricular defect
2. Pulmonic stenosis
3. Overriding aorta
4. Right hypertrophy
