Module 1 ALS: initiating advanced life
support 100% CORRECT
3 steps to start advanced life support - ANSWER -initiate monitoring (ECG and End Tidal CO2)
-obtain vascular access
-administer reversal agents
electrocardiogram (ECG) - ANSWER A recording of the electrical activity of the heart
When should ECG leads be added to patient? - ANSWER After BLS has been started
What does it mean to have the ECG equipment kept in a "ready" state? - ANSWER -ECG monitor with
leads attached
-clips or stick-on electrode patches readily available
-get to improve contact
Lead placement on ECG (placement) - ANSWER Right forelimb, left forelimb, and left hindlimb
ECG lead colors and placement - ANSWER White: right forelimb
Black: left forelimb
Red: left hindlimb
*smoke over fire
What do you do if you cannot remember where the ECG leads are supposed to go? - ANSWER Place the
leads on 3 different limbs
This is sufficient for CPR
, Alligator clamp electrodes description - ANSWER Coupling material needed to provide a low resistance
contact through the fur to the skin
Pre-gelled adhesive electrodes description - ANSWER Preferred during CPR
-they can be placed on the foot pads of the appropriate limbs and quickly taped into place using white
medical tape
-they are much less likely to become dislodged than alligator clamp electrodes during chest
compressions and movement of the patient
How is contact improved when attaching ECG nodes? - ANSWER -electrode gel will improve contact
between the electrode and the patient and give a cleaner ECG signal
-non flammable coupling gels should always be used for electrodes that are not pre-gelled
Why should alcohol not be used during CPR? - ANSWER Alcohol should NEVER be used as a coupling
material during CPR. It is highly flammable and may ignite if electrical defibrillation is necessary
ECG monitor compatibility - ANSWER If using an electrical defibrillator, ensure that either the
defibrillator's ECG monitor is used or that any external ECG unit is safe for defibrillation use.
Full _____minutes cycles of chest chest compressions without interruption are recommended to
optimize perfusion to the brains and heart - ANSWER 2 minutes
It takes approximately ____minute of uninterrupted chest compressions to attain a maximal steady state
blood flow to the heart and other tissues. - ANSWER 1 minute
What does premature pausing of chest compressions prevent? - ANSWER Development of maximal,
steady state blood flow and results in poor perfusion of the tissues. Chest compressions should never be
stopped solely to evaluate the ECG, but instead the ECG should be evaluated during the brief pauses
between 2 minutes cycles.
Should chest compressions ever be paused? - ANSWER Chest compressions should never be stopped
solely to evaluate the ECG, but instead the ECG should be evaluated during the brief pauses between 2
minutes cycles.
