Brief Summary

High-quality chest compressions are critical for outcomes after pediatric cardiac arrest, yet rescuer ergonomics and bed height may adversely affect compression quality and fatigue. This randomized crossover simulation study will evaluate how four different bed-height settings influence pediatric CPR quality and rescuer biomechanics. Pediatric emergency medicine residents will perform 2-minute chest-compression-only CPR on a pediatric manikin placed on a hospital bed under four bed-height conditions in randomized order across separate sessions. CPR quality metrics from the manikin's feedback system, rescuer fatigue, physiologic responses, and arm angle over time will be compared to identify an ergonomically optimal bed-height approach.

Outcome Measures

Primary Outcomes (1)

• Correct chest compression depth (%, QCPR-defined)

  Percentage of compressions meeting the target depth criteria as calculated by Laerdal Little Junior QCPR manikin sensors. (Recorded separately for each bed-height condition.)

  During each 2-minute chest compression-only CPR session (per bed-height condition).

Secondary Outcomes (7)

• Average chest compression depth (mm)

  During each 2-minute chest compression-only CPR session (per bed-height condition).

• Average chest compression rate (compressions/min)

  During each 2-minute chest compression-only CPR session (per bed-height condition).

• Correct chest recoil / release (%, QCPR-defined)

  During each 2-minute chest compression-only CPR session (per bed-height condition).

• Perceived exertion (Borg RPE score)

  Immediately after each 2-minute CPR session.

• Change in heart rate (beats/min)

  From immediately before to immediately after each 2-minute CPR session.

Study Arms (4)

Fixed Standard Bed Height (58 cm)

EXPERIMENTAL

Participants perform 2 minutes of single-rescuer, chest-compression-only pediatric CPR on a manikin placed on a hospital bed set to a fixed standard height of 58 cm.

Other: Fixed Standard Bed Height (58 cm)

Anthropometry-Based Bed Height (Patella Midpoint)

EXPERIMENTAL

Participants perform 2 minutes of single-rescuer, chest-compression-only pediatric CPR on a manikin with the hospital bed height adjusted to the participant's patella midpoint (knee midpoint) reference.

Other: Anthropometry-Based Bed Height (Patella Midpoint)

Anthropometry-Based Bed Height (Lower One-Third of Patella-ASIS Distance)

EXPERIMENTAL

Participants perform 2 minutes of single-rescuer, chest-compression-only pediatric CPR on a manikin with the hospital bed height adjusted to the lower one-third point of the distance between the patella and the anterior superior iliac spine (ASIS).

Other: Anthropometry-Based Bed Height (Lower One-Third Patella-ASIS)

Self-Selected Bed Height

EXPERIMENTAL

Participants perform 2 minutes of single-rescuer, chest-compression-only pediatric CPR on a manikin with the hospital bed height set to the participant's self-selected "most comfortable/optimal" height.

Other: Self-Selected Bed Height

Interventions

Fixed Standard Bed Height (58 cm) OTHER

Hospital bed height is set to a fixed standard height of 58 cm for the CPR session.

Fixed Standard Bed Height (58 cm)

Anthropometry-Based Bed Height (Patella Midpoint) OTHER

Hospital bed height is adjusted to the participant's patella midpoint reference before the CPR session.

Anthropometry-Based Bed Height (Patella Midpoint)

Anthropometry-Based Bed Height (Lower One-Third Patella-ASIS) OTHER

Hospital bed height is adjusted to the lower one-third point of the distance between the patella and ASIS before the CPR session.

Anthropometry-Based Bed Height (Lower One-Third of Patella-ASIS Distance)

Self-Selected Bed Height OTHER

Participant selects the bed height they perceive as optimal/comfortable prior to the CPR session.

Self-Selected Bed Height
