Brief summary
In this prospective, single-center, randomized, self-controlled crossover manikin simulation study, participitants performed 2 minutes of single-rescuer CPR (30:2 compression-to-ventilation ratio) with each of the four techniques (the two-finger (2F), three-finger (3F), heel-of-one-hand (HOH), and two-thumb (2T) techniques) in a randomized order, with at least 10 minutes of rest between techniques. Chest compression depth, rate, release velocity, and the proportion of compressions within the target range were recorded using a feedback device. Provider fatigue and perceived difficulty (modified Borg scale) were assessed as secondary outcomes
Interventions
PROCEDURETwo-Finger (2F) Technique
Participants perform single-rescuer basic life support CPR on an infant manikin for 2 minutes using the two-finger chest compression technique with a 30:2 compression-to-ventilation ratio
PROCEDUREThree-Finger (3F) Technique
Participants perform single-rescuer basic life support CPR on an infant manikin for 2 minutes using the three-finger chest compression technique with a 30:2 compression-to-ventilation ratio.
PROCEDUREHeel-of-One-Hand (HOH) Technique
Participants perform single-rescuer basic life support CPR on an infant manikin for 2 minutes using the heel-of-one-hand chest compression technique with a 30:2 compression-to-ventilation ratio.
PROCEDURETwo-Thumb (2T) Technique
Participants perform single-rescuer basic life support CPR on an infant manikin for 2 minutes using the two-thumb chest compression technique with a 30:2 compression-to-ventilation ratio.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Mean Chest Compression Depth | 2 minutes of CPR application | Measured in centimeters (cm) using a CPR feedback device. |
| Mean Chest Compression Rate | 2 minutes of CPR application | Measured as compressions per minute |
| Chest Compression Release Velocity | 2 minutes of CPR application | Measured in millimeters per second (mm/s) |
| Compressions Within Target Range | 2 minutes of CPR application | Percentage of compressions performed within the target range. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Provider Fatigue | During the 2-minute CPR application | Defined and recorded as a 10% reduction in compression depth sustained over three consecutive compressions. |
| Perceived Difficulty | Assessed immediately after each 2-minute application. | Subjective level of difficulty assessed using the modified Borg scale, graded from 0 (no difficulty) to 10 (most severe difficulty). |
