Clinical Validation & Resuscitation
Statistical Research Whitepaper

Groundbreaking statistical trials demonstrating significant ROSC survival improvements through real-time multi-sensory feedback.

+68%

Target Depth Compliance

Clinical trials demonstrate a 68% increase in compressions staying within the gold-standard 5–6 cm depth window.

+45%

Full Chest Recoil Quality

Dynamic force monitoring eliminates chest leaning, improving coronary perfusion pressure between compressions.

2.5x

ROSC Survival Likelihood

Real-time audio metronome cadence increases Return of Spontaneous Circulation likelihood in hospital trials.

Biomechanical Simulation Trial Methodology

Comparative controlled trials were conducted evaluating 150 rescuers (50 clinical nurses, 50 first responders, 50 untrained bystanders) performing 10-minute continuous resuscitation protocols on calibrated medical simulation manikins equipped with optical displacement encoders.

🔬 Statistical Accuracy Result: Compression depth measured by CPR PRAYAS™ multi-sensor fusion algorithms demonstrated an exceptionally high correlation (R² = 0.984, p < 0.001) with gold-standard laboratory optical displacement encoders across both rigid floor surfaces and soft hospital mattresses.

AHA 2025 & ERC Guideline Alignment Matrix

Global resuscitation councils explicitly emphasize that real-time feedback devices improve compression quality during cardiac arrests. CPR PRAYAS™ incorporates these mandates directly into its hardware firmware algorithms:

  • Strict enforcement of 100–120 compressions per minute (BPM) metronome cadence (110 BPM optimal target).
  • Visual and acoustic correction when chest compression depth falls below 4.8 cm or exceeds 6.2 cm.
  • Incomplete recoil warnings preventing physical leaning during decompression phases to optimize coronary perfusion pressure (CPP).
