Chapter 17- AED maintenence Flashcards
What is one of your primary missions as an EMT?
To deliver an electrical shock to a patient in VF
VF stands for ventricular fibrillation, a life-threatening heart rhythm that requires immediate attention.
What is essential for delivering a shock to a patient in VF?
A functioning AED
AED stands for Automated External Defibrillator.
What should you read to become familiar with the maintenance procedures for an AED?
The operator’s manual
This manual provides specific guidelines for the upkeep of the AED.
Who may inquire about the AED’s malfunction on the scene?
System’s administrator, medical director, local newspaper reporter, family’s attorney
These individuals may seek accountability regarding the AED’s performance.
What is the main legal risk in using an AED?
Failing to deliver a shock when one was needed
This can have serious legal ramifications for the EMT.
What are the three most common errors in using certain AEDs?
Failure to shock fine VF, applying AED to a moving patient, turning off AED before analysis or shock is complete
These errors can hinder effective resuscitation efforts.
What are some operator errors associated with AED use?
Failing to apply AED to a cardiac arrest patient, not pushing analyze or shock buttons, pushing power instead of shock button
Operator errors can prevent the AED from functioning properly.
What is a rare but possible issue with the AED?
The AED can fail
Ideally, such failures are identified during routine maintenance.
What is a common reason for failure to deliver a shock?
A battery that did not work due to improper maintenance
Regular maintenance is crucial for the AED’s reliability.
How often should you check your AED equipment?
Daily at the beginning of each shift
Daily checks help ensure the AED is functional when needed.
What should you ask the manufacturer regarding AED maintenance?
For a checklist of items that should be checked daily, weekly, or less often
This checklist aids in systematic maintenance and ensures compliance.
What can occur when the AED is applied to a responsive patient with a rapid heart rate?
The patient may lose his or her pulse and go into cardiac arrest
Most AEDs identify a regular rhythm faster than 150 or 180 beats/min as VT.
Under what condition should you apply the AED?
Only to unresponsive pulseless patients
This is to avoid shocking VT in a patient with a pulse.
What should you do if the AED fails while caring for a patient?
Report the problem to the manufacturer and the US Food and Drug Administration
Follow appropriate EMS procedures for notifying these organizations.
What is the threshold heart rate that AEDs identify as VT?
Faster than 150 or 180 beats/min
This rhythm should be shocked if the patient is pulseless.
True or False: Shocking a patient with a pulse can lead to cardiac arrest.
True
Shocking VT in a patient with a pulse may result in losing the pulse.
