Need to add more on slides 13-15 and need to review/add everything form 23 forward
What dosage of Atropine should be given to a kid < 5Kgs?
0.1mg (min dosage)
what is the max dosage dose of Atropine given to a kid > 25kg?
0.5mg
What are signs of a sinus tachycardia on a ECG?
- Infants < 220bpm
- Child < 180bpm
- Slow onset of increased HR
- Fever/Hypovolemia
- Rate varies w/stim
- Visible P waves
How do you differentiate a developing SVT from sinus tachycardia?
HR will rapidly increase to 180 and beyond.
- The P-waves will disappear
What are signs of SVT on a ECG?
- Infant HR > 220bpm
- Child HR > 180
- Abrupt start/stop
- pulmonary edemas
- Constant, fast rate
- Absent P waves
How can SVT lead to pulmonary edema?
- What is the snowball affect?
The heart may not have enough time to fill adequately during diastole
- Increase ventricular load and decreased diastolic time
- Causes the heart’s stroke volume can be reduced, leading to a lower cardiac output.
- Blood can pool in the alvoelar sacs, impairing O2 exchange = pink frothy secretions
What QRS is considered too long?
QRS wider than 0.12 secs
When do you use adenosine?
Tachycardias, you usually don’t use more than 2 doses (max dose)
What are the shock energies used for Cardiac Arrest?
- First shock: 2J/Kg
- Second shock: 4J/Kg
- Subsequent shocks: >4J/Kg
- Max dose: 10J/Kg
What is the dosage and frequency for Epi used for cardiac arrest if given by IV/IO?
0.01mg/kg repeated every 3-5 mins
What is the dosage and frequency for Epi used for cardiac arrest if given by ETT?
0.1mg/kg
What is the dosage and frequency for Amiodarone used for cardiac arrest if given by IV/IO?
5mg/kg, but only up to 2 times.
What shock energy pathway should you follow?
2,4,10 J/kg
- You don’t want to to waste critical time shocking inefficiently.
- AKA go big or go home after that point.
What are the H’s and T’s of Cardiac Arrest?
Reversible causes of cardiac arrest

What drugs are given for tachycardias?
Atropine and Epi
What drugs are given for Ventricular tachy?
none, cardiovert
How is Cardiogenic Shock distinguished from Hypovolemic shock?
Cardiogenic shock is usually accompanied by increased WOB
- body attempts to raise HR and SV by pumping more blood.
Hypovolemia = less volume, which means that the hearts ability to pump is not affected. So rate may increase at some point, but WOB won’t occur as there is no extra effort to pump blood.
What is Obstructive Shock?
Inadequate contractility of the heart BECAUSE of external forces preventing the heart from contracting
What are some pathologies that may cause Obstructive Shock?
- Cardiac tamponade
- Tension pneumothorax
What are potential causes of Hypovolemic Shock?
- Hemorrhage
- Water loss (dehydration) due to diarrhea or vomiting (third spacing)
Why is Hypovolemic shock problematic?
- Snowball affect?
Decreased blood = decreased preload to the heart which causes low blood pressure
- Afterload will increase because vasoconstriction is stimulated in order to maintain adequate blood pressure.
What are signs of Hypovolemic shock?
- Possible tachypnea
- Tachycardia
- Adequate or Low Blood Pressure
- Narrow pulse pressure
- Slow capillary refill
- Weak peripheral pulses w/normal central pulses
- Decrease urine output
- Decreased LOC
What is the pathophysiology of Distributive Shock?
Blood inappropriately distributed in the vasculature
- vasculature has relaxed and dilated to the point of inadequate BP
What are 3 types of Distributive Shock?
- Septic Shock
- Anaphylactic Shock
- Neurogenic Shock
How are preload, contractility, afterload in Septic Shock?
- Decreased preload
- Normal/decreased contractility
- Afterload varies
How are preload, contractility, afterload in Anaphylactic Shock?
- Decreased preload
- Contractility varies
- Afterload is low in left ventricle and high right ventricle
How are preload, contractility, afterload in Neurogenic Shock?
- Decreased preload
- Normal contractility
- Afterload is decreased
What are treatments for Hypovolemic shock?
Give fluids (Isotonic Crystalloids -> Normal saline or lactated ringers)

- minimize interruptions and achieve a depth of 1/3 of chest
What ratio compression to ventilation ratio do we aim for if there is no advanced airway?
- 30:2 compression to ventilation ratio for one provider
- 15:2 compression to ventilation ratio for two providers
How many breaths are given if there is a advanced airway?
- 10-15 breaths per minute for one provider
- 20-30 breaths per minute for two providers

- Avoid hypoxemia
- Avoid hypercarbia
- Avoid hyperthermia
- Avoid hypotension

Defibrillation vs Cardioversion?
(needs confirmation)
- Cardioversion = making one rhythm into another.
- Synchronized cardioversion is where you shock the R wave.
- Defib = unsynchronized cardioversion.
