Using a Cardiac Science Defibrillator During Sudden Cardiac Arrest: Male vs. Female Casualties

Sudden Cardiac Arrest (SCA) requires immediate action to improve survival chances. Using a defibrillator, such as the Cardiac Science Powerheart G5 Automated External Defibrillator (AED), significantly enhances outcomes when paired with high-quality CPR. While the process is the same for all casualties, there are some important considerations when treating male and female casualties.

 

Steps for Using a Defibrillator

 

1. Assess the Casualty and Call Emergency Services
Check for responsiveness and normal breathing. If the casualty is unresponsive and not breathing normally, call 999 and retrieve the defibrillator.


2. Prepare the Casualty and the AED
Begin CPR immediately. Once the defibrillator is ready, turn it on and follow the voice prompts to prepare the pads.


3. Apply the Pads Correctly
Position the pads as instructed:

  • One on the casualty’s upper right chest.
  • The other on the lower left chest, below the armpit.

 

Considerations for Male and Female Casualties

 

Male Casualties

  • Chest Hair:
    If chest hair prevents the pads from adhering, quickly shave the area using the razor provided in the AED kit. This ensures proper contact for effective shock delivery.
  • Muscle Definition:
    For casualties with a particularly muscular chest, ensure the pads are firmly pressed against the skin.

 

Female Casualties

  • Clothing and Bra Removal:
    Remove clothing and bras, especially those with underwire, to allow proper pad placement. AED kits include scissors to assist with this. Responders should act promptly and confidently to avoid delays.
  • Breast Tissue:
    For casualties with larger breasts, gently move the tissue aside to position the pads directly on the chest wall. Ensure the pads do not overlap or rest on the breast.
  • Pregnancy:
    If the casualty is pregnant, defibrillation is safe for both the mother and baby. Deliver high-quality CPR and follow the AED prompts as you would for any adult.

Acting Without Hesitation

Studies indicate that female casualties are less likely to receive bystander CPR or defibrillation, often due to hesitation or concerns about modesty. Taking immediate action with a defibrillator increases survival chances significantly. Education and awareness can help overcome barriers and ensure everyone receives the life-saving care they need.
