Emergency Medical Procedures (Passage 5) Flashcards
Who performs pre-hospital EMS? (3)
- Paramedics
- EMTs
- Medical First Responders (MFRs)
What is CPR designed to do? (2)
- To restore normal breathing and
2. assist with circulation after cardiac arrest.
What does CPR do with regard to cardiac output?
- It does not maintain normal cardiac output
- but does support delivery of oxygen to the heart and brain.
- Buys time until defibrillation and advanced care can restore normal heart action.
What was the difference in survival of cardiac arrest with defibrillation between immediate bystander CPR and no bystander CPR?
Those with bystander CPR were twice as likely to survive.
What does “ABC” stand for in terms of EMS?
A - first open the airway
B - check for normal breathing and give rescue breaths
C - check circulation
If you provide mouth-to-mask ventilation without supplemental oxygen, how should the rescue breaths be delivered?
Slowly over 2 seconds.
What provides the best possibility of survival after sudden cardiac arrest?
Immediate CPR and prompt defibrillation.
What skills does Paramedic training allow? (2)
- Advanced airway skills
2. Advanced cardiac life support
What are 2 examples of advanced airway skills?
- airway tube placement
2. emergency creation of an airway (crichothyrotomy)
What is a “Mega-code” training scenario?
Usually multiple medical or trauma scenarios wrapped into one large training scenario.
They are typically acute, dynamic, rapidly evolving scenarios based on the use of many various acute care EMS protocols.
What are 2 examples of practical therapeutic manipulation?
- CPR
2. the Heimlich maneuver
What simple axiom is the basis of the Mega-code scenario?
What is a strong example of this?
Certain medical modalities must be accomplished before certain others would be effective.
The simple order of Airway, Breathing, and Circulation.
What references can be used to identify standards related to Mega-codes? (2)
- AHA literature
2. National Association of EMT testing standards
How do you know the AED has detected a cardiac rhythm and an electric shock is indicated?
The AED will signal audibly and visually.
At what levels does the AED deliver shocks at increasing wattages?
120 Joules
150J
200J
What is the significance of an algorithm, decision tree, or flow chart in operating an AED?
An algorithm defines each step in an orderly manner and,
one step must be completed and,
the rescuer must evaluate the outcome of that step prior to,
moving to the next appropriate step.
How is the AED algorithm self-limiting?
It requires the rescuer to return to previous described steps, to repeat and re-evaluate the step to determine if a change in the direction of care must be made.
AED ALGORITHM
Assess Airway and Breathing –> Not Breathing
Then what?
Give 2 breaths;
Check pulse
AED ALGORITHM
If No Pulse, then what?
Begin chest compressions; Apply AED; Stop CPR; Stand clear; Analyze
AED ALGORITHM
Shock indicated and the AED charges.
Then what?
AED delivers shocks @ 120J, 150J, 200J;
Check pulse
AED ALGORITHM
You check pulse and there is NO pulse.
Then what?
CPR for 1 minute;
Stop CPR, stand clear, analyze
AED ALGORITHM
If there is a pulse (< = 30), then what?
CPR for 1 minute;
Check pulse
AED ALGORITHM
If there is a pulse (> 30), then what?
Monitor pulse
Evaluate for < = 30 or > 30 {and act accordingly}
AED ALGORITHM
Assess Airway and Breathing, BREATHING ADEQUATE
What next?
Check pulse; Pulse present, ANY RATE; Ventilate for 1 minute Re-check pulse after 1 minute {act accordingly}
