The Effect of T-CPR on the Quality of CPR and AED Use

The purpose of the study is to examine the effect of telephone assistance and standardized basic life support courses on the quality of cardiopulmonary resuscitation (CPR) and the use of automated external defibrillator (AED).

The investigators hypothesize that bystanders can provide compressions in correct frequency and use an AED correctly as well as safely from telephone instructions but that correct and successful ventilations including correct open airway require training on a course.

About this study

The study aims at answering the following research questions:

  • How is the quality of CPR and use of AED when performed by an inexperienced bystander who receives telephone assistance compared to the quality when performed by a trained bystander, who has passed a standardized European Resuscitation Council (ERC) course in basic life support (BLS) but does not receive telephone assistance?
  • How is the quality of CPR and use of AED when performed by a trained bystander who has passed a standardized ERC course in BLS and who receives telephone assistance compared to the quality when performed by a trained bystander who does not receive telephone assistance?

The questions are sought answered through simulated cardiac arrest scenarios in non-classroom settings.

Participants are recruited from ERC courses in BLS.

Participants are randomised to one of three groups (stratified for course type using computer-generated randomisation lists with blocks of variable sizes):

  • Cardiac arrest scenario test before BLS course with telephone-assistance.
  • Cardiac arrest scenario test after BLS course, no telephone-assistance.
  • Cardiac arrest scenario test after BLS course with telephone-assistance.

Treatment and study plan

T-CPR

Other

Participants receive telephone instructions in cardiopulmonary resuscitation (T-CPR) from the Emergency Medical Services in Copenhagen during the cardiac arrest scenario test.

ERC standardized BLS course

Other

Participants will receive and complete the standardized course in basic life support (BLS) from European Resuscitation Council (ERC).

Primary outcomes

  1. Compression depth

    Time frame: 8 minutes

    Keeps a compression depth as recommended by International Liaison Committee on Resuscitation (ILCOR) (5-6 cm) on at least 50 % of compressions (yes/no). Measured by advanced manikin.

  2. Compression rate

    Time frame: 8 minutes

    Rescuer keeps a compression rate of approximately 100-120 compressions per min. throughout the CPR (yes/no). Measured by advanced manikin.

  3. Shock delivered

    Time frame: 8 minutes

    Shock delivered with AED (yes/no). Assessed by ERC instructor.

Secondary outcomes

  1. Hands-of time

    Time frame: 8 minutes

    Relevant actions of resuscitation within more than 75 % of the test time (yes/no). Measured as no flow time by advanced manikin.

  2. Responsiveness

    Time frame: 8 minutes

    Shakes AND shouts (yes/no). Assessed by ERC instructor.

  3. Open airway

    Time frame: 8 minutes

    Opens or correctly tries to open mouth (chin lift OR jaw thrust) (yes/no). Assessed by ERC instructor.

  4. Assess breathing

    Time frame: 8 minutes

    Looks, listens AND feels for normal breathing (yes/no). Assessed by ERC instructor.

  5. Recoil/lean

    Time frame: 8 minutes

    Full rise on at least 50 % of all compressions (yes/no). Measured by advanced manikin.

  6. Rescue breaths

    Time frame: 8 minutes

    More than 400 mL for at least 50 % of all ventilations (yes/no). Measured by advanced manikin.

  7. Ratio

    Time frame: 8 minutes

    Acceptable range 28-32:2 (yes/no). Assessed by ERC instructor.

  8. Activate AED

    Time frame: 8 minutes

    Activates AED immediately upon arrival (yes/no). Assessed by ERC instructor.

  9. Attachment of AED pads

    Time frame: 8 minutes

    Correct attachment of AED pads according to the picture in protocol (yes/no). Assessed by ERC instructor.

  10. Stand clear

    Time frame: 8 minutes

    Ensures safety by looking around and verbally announcing delivery of shock (yes/no). Assessed by ERC instructor.

  11. Compression depth 2

    Time frame: 8 minutes

    Percentage of compressions with a depth within the recommendations from ILCOR (5-6 cm) (%). Measured by advanced manikin.

  12. Compression rate 2

    Time frame: 8 minutes

    Average rate of compressions (compressions/minute). Measured by advanced manikin.

  13. Rescue breaths 2

    Time frame: 8 minutes

    Percentage of ventilations with more than 400 mL (%). Measured by advanced manikin.

  14. Time to first compression

    Time frame: 8 minutes

    Time from scenario start to first compression. Assessed by ERC instructor.

  15. Hand placement

    Time frame: 8 minutes

    Correct hand placement in at least 50 % of compressions (yes/no). Measured by advanced manikin.
