Study Notes

CPR Procedures and Steps

Unresponsive Person with Gasping Sounds and No Pulse:
- Initiate CPR if gasping is not normal breathing.
- Provide rescue breaths only if gasping is not normal breathing.
- Monitor the patient if gasping is considered normal breathing.
- Begin CPR if gasping is normal breathing.
- Start chest compressions only if gasping is considered normal breathing.

Ineffective Rescue Breaths

If two rescue breaths aren't effective within 10 seconds, reposition the airway.
If repositioning doesn't work, switch to mouth-to-mouth.
If mouth-to-mouth doesn't work, continue CPR.

Initial Steps for Cardiac/Respiratory Arrest (Alone)

Check for safety.
Check for response.
Get help immediately.
Activate EMS or call emergency medical services.
If available, get an AED (automated external defibrillator).
Initiate CPR if appropriate.

Post-Shock AED Procedure

Reassess the patient for a pulse.
Continue CPR if the pulse is absent; otherwise, continue monitoring.
If needed immediately call for help/EMS.

Unresponsive Victim with No Pulse (Park Scenario)

Tell a bystander to call 123 (or appropriate emergency number) and get an AED.
Begin CPR, starting with chest compressions.
Wait for the bystander to come back with AED.
Do not perform abdominal thrusts.
Do not give rescue breaths every 5 seconds unless gasping is not normal breathing

BLS (Basic Life Support) Steps for Adults

Assess the individual for responsiveness.
Activate EMS or call the emergency medical services (EMS).
Obtain an AED, if available.
Initiate CPR if needed and possible.

Single Rescuer CPR (After EMS Activation)

Obtain an AED or defibrillator and the necessary equipment.
Begin CPR.

Pulse Assessment Location for Cardiac Arrest

Carotid or femoral artery (typically carotid artery is preferred).

AED Use with Rescuer Present

Place AED pads on the victim's bare chest.
AED will shock the patient if the rhythm analysis indicates it's time shock.
Continue CPR immediately after delivering shock.

AED Operation Steps

Turn on the AED
Place electrode pads on the patient.
Analyze the rhythm.
Deliver the shock if indicated.

Unresponsive Victim CPR Steps (Absent Pulse and Breathing)

Immediately begin chest compressions without delay.
Request help and activate EMS or call emergency services.

Pulse Verification Time Limit During Basic Life Support

No more than 10 seconds

CPR Quality Criteria

Push hard and fast
Minimize interruptions.
Initial chest compressions should be started as quickly as possible.

Post-AED Shock Actions

Reassess the victim for a pulse.
Continue CPR, if a pulse is not detected.

BLS Steps for Adults/Cardiac Arrest

Check for responsiveness.
Activate EMS
Check for pulse and breathing.
Begin CPR if necessary and possible.

CPR Victim Recovery Signs

Waking up.
Moving.
Breathing normally.
Opening eyes.

Sudden Cardiac Arrest Symptoms

Lack of pulse.
Loss of consciousness.
Sudden collapse.
Absence of breathing.

Hand Placement on Chest During CPR

Lower half of the sternum.

Airway Opening for Unconscious Adult (No Trauma)

Use head tilt and chin lift to open the airway.

Victim Requiring High Quality CPR

Unresponsive victim with no pulse and no breathing.
Responsive victim with breathing problems who has a pulse <60/minute

Importance for Effective Victim Survival During Cardiac Arrest

Performing high quality CPR.

Importance of Chest Recoil in CPR

The heart will adequately refill between compressions.
It reduces the risk of rib fractures.

Importance of Defibrillation (AED)

Prevents recurrent cardiac arrest
Restores effective heart rhythm

Pediatric CPR Compressions to Breaths Ratio

15 compressions to 1 breath
30 compressions to 2 breaths

Effective Breath Technique During Mouth-to-Mouth

Observe chest rise with each breath.

AED First Use Step

Apply pads.

Unresponsive Patient Before Starting CPR

Call 123 to activate EMS or emergency medical services. (Check local emergency number).

Pediatric Arrest 5 Breaths Before Cardiopulmonary Resuscitation

Pediatric patients in cardiac arrest often have respiratory issues.

Correct Chest Compression Depth for Adults

At least 3 cm deep.

Adult CPR Chest Compression Rate

100 to 120 compressions per minute (or about 2 per second).

False Statement about Chest Compressions During CPR

Pressure should not be completely released after each compression.

Intubation BLS Interruption Time

BLS should not be interrupted for more than 30 seconds when performing intubation.

Pulse Check Location in Unresponsive Adults

Carotid artery.

Correct Sternum Compression Depth

2-5 cm

Airway Opening with Head and Neck Injury

Perform a jaw thrust maneuver.

CPR Chest Compression Location

Upper part of the sternum.

A-B-C in Basic Life Support

Airway, Breathing, Circulation

Cardiac Arrest Diagnosis Criteria

Loss of consciousness with absence of carotid pulses for 3 seconds.

Goal of Basic Life Support

Maintain organ perfusion until definitive treatment can be administered.

Cardiac Arrest Definition

An abrupt cessation of cardiac pump function.

Determining Responsiveness (No Trauma)

Gently shake the patient and call his name.

Essential CPR Compression Characteristics

Begin chest compressions within 10 seconds of recognizing cardiac arrest.
Push hard and fast
Minimize interruptions.

Two Rescuer CPR Role-Switching Frequency

Every two cycles of chest compressions.

Child vs. Adult Pulse Check Location (1-puberty)

Brachial artery.

Adult BLS Steps

Assess the individual, give two rescue breaths
Defibrillate, and start CPR.

Important First-Rate CPR Characteristics

Begin chest compressions within 10 seconds.
Perform continuous compressions; pushing hard and fast.
Minimize interruptions during compressions.

CPR Compression/Ventilation Ratio

30 compressions per 2 ventilations
