Steps to Performing the EC-Clamp Correctly

E-C Clamp Technique

The EC-Clamp is a technique used for holding the mask of manual ventilation on the face during cardiopulmonary resuscitation. Healthcare providers often use this technique during resuscitation efforts. It is an effective way to deliver breaths to a person who has stopped breathing. CPR training, including online courses, can help you learn and feel confident in performing CPR techniques like the EC-Clamp, which is crucial in rescue situations. Using a barrier device during CPR helps protect both the rescuer and the victim. Here are the detailed steps for performing the EC-Clamp technique in CPR:

Step-by-Step Guide

1. Tilt the Victim's Head Slightly Back

To open the airway, gently tilt the victim's head back. This helps align the airway and allows for effective ventilation.

2. Place the Mask Over the Victim's Face

Position the mask over the victim's face, ensuring it covers both the mouth and nose. The mask should fit snugly to create an effective seal.

3. Form the EC-Clamp

Using Your Least Dominant Hand

  • Form a “C” Shape: Use the thumb and index finger of your least dominant hand to form a “C” shape around the top and bottom edges of the mask. Place the thumb along the top edge of the mask and the index finger along the bottom edge by the chin.
  • Support with Other Fingers: Use the other three fingers of the same hand to form an “E” shape against the side of the victim's face. These fingers will help secure the mask and maintain a tight seal.

4. Ensure a Tight Seal

Once the mask is in place and the EC-Clamp is formed, ensure the seal is tight. This is crucial to prevent air from escaping when breaths are administered.

5. Administer CPR Breaths

Using the Bag Mask Ventilation (BVM)

  • Squeeze the Bag: With your dominant hand, squeeze the bag attached to the mask to deliver a breath. Each squeeze should be firm and consistent. Using the bag valve mask (BVM) for bag mask ventilation is crucial for effective oxygenation and ventilation until a definitive airway is secured. A self inflating bag is often used in this process, and it is important to squeeze the reservoir bag to deliver adequate ventilation.
  • Watch for Chest Rise: Observe the victim’s chest as you squeeze the bag. A proper breath will cause the chest to rise. If you do not see the chest rise, check the mask seal and reposition if necessary.

6. Recheck and Adjust

If the chest does not rise when you squeeze the bag, repeat the process:

  • Ensure the victim’s head is properly tilted back.
  • Check and adjust the seal of the mask, ensuring visible chest expansion.
  • Reapply the EC-Clamp technique and attempt to deliver another breath.

    Importance of Learning the EC-Clamp Technique

    Benefits of Proper Technique

    • Effective Ventilation: Ensures that each breath is delivered efficiently, providing the necessary oxygen to the victim. Achieving an adequate tidal volume is crucial for effective ventilation during CPR and other medical procedures.
    • Protection: Using a barrier device protects both the rescuer and the victim from potential infections.
    • Confidence in Emergency Situations: Being well-trained in CPR and techniques like the EC-Clamp boosts confidence and preparedness in emergency situations.

      CPR and Survival Rates

      CPR helps maintain oxygen and blood flow to the victim’s organs, sustaining life until professional medical help arrives. The sooner CPR is initiated, the greater the chances of survival and reduced recovery time. The average response time for paramedics ranges from four to ten minutes after receiving a 911 call. However, a victim’s survival rate decreases significantly after the first two minutes without CPR or medical assistance. Every minute counts, making it crucial to act promptly and effectively.


      Learning the EC-Clamp technique and other CPR skills can save lives. Medical sciences play a crucial role in advancing CPR techniques and training. CPR training, including online courses, equips you with the knowledge and confidence to respond to emergencies. The ability to perform CPR effectively can make a significant difference in survival rates and recovery outcomes. Get CPR trained today and be prepared to save a life when it matters most.
