Infant under 1 year CPR | head tilt chin lift, 12-20 breaths per min, 2-3 fingers 1/2-1 inch 100/min ratio 15:2 |
Newborn birth to 1 month CPR | head slightly extended, 40-60 breaths, 2 fingers or thumbs 1/2-3/4 inch 90/min ratio 3:1 |
What is hypotension | low blood pressure, poor capillary refill, weak thready pulse |
What do you treat hypotension with | fluid, dopamine, dobutamine |
What is bradycardia | hr less than 60 adult, less than 100 in infant |
What is bradycardia treated with | atropine, dopamine and epinephrine for an adult, epinephrine and atropine for children, external pacemaker |
What is ventricular arrhythmias | PVC treat with oxygen and lidocaine, ventricular tachycardia treat with defibrillation 360 joules or epinephrine, amiodarone, or lidocaine |
What do you treat ventricular fibrillation with | defib 360 joules, epinephrine, amiodarone, or lidocaine, if patient has metabolic acidosis administer sodium bicarbonate |
What asystole | confirm 2 leads treat with epinephrine, atropine, DO NOT defibrillate |
What is cardioversion | therapeutic procedure that involves administering a low voltage current to the heart tissue in an attempt to convert a cardiac dysrhythmia to normal sinus rhythm, synchronizing switch is on, 50-100 joules, o2 should be present |
In cardioversion, if ventricular fibrillation occurs then | check pulse first, then turn off synchronizing switch, increase to 200 joules and defibrillate |
What strong short acting sedative is given prior to the cardioversion | midazolam(versed) |
What is defibrillation | used when emergency cardiac dysrhythmias are present |
What are the indications for defibrillation | pulseless ventricular tachycardia, ventricular flutter, ventricular fibrillation |
How many joules are sufficient for defibrillation | 360 joules |
Criteria for the ideal resuscitation bag self inflating, ideal stroke volume | adult 800 ml(1000-1800) infant 200 ml |
What are the safety features for the self inflating resuscitation bag | true non rebreathing valve, universal connector with a 22 mm OD and 15 mm ID, patient valve that does not jam at 15 liters per minute, oxygen inlet flow to provide that highest FIO2 possible |
What does the mask look like for a self inflating resuscitation bag | well fitting, shapeable, transparent |
What does the reservoir give | 95-100% oxygen (at 15 L/min), quick attachment, non bulky |
When trouble shooting a self inflating bag excessively high flow may cause | valves to jam, use 15 L/min or low range of flush |
What are the advantages of the mouth to valve mask ventilation | eliminates direct contact with the patient, supplemental o2 can be administered up to 50% oxygen concentration with a flow rate at 10L/min, a one way valve between the mask and the practitioners mouth eliminates the exposure to exhaled air |
