Paramedic elevation doesn't help CPR in obesity simulation

Effect of Body Position on Chest Compression Quality During CPR in an Obesity Simulation Model: A Randomized Crossover Trial
Prehospital Emergency Care · Added 1 September 2026

Randomised crossover simulation trial testing whether 10cm elevation of paramedics improves chest compression quality in obese manikins — it didn't, obesity still impaired compression depth by ~18mm despite increased rescuer effort

Study type

Simulation

Design

Randomised crossover simulation trial

Participants

60 paramedics

Main finding

Compression depth reduced ~18 mm with simulated obesity (adjusted mean differences 17.83 mm and 18.44 mm vs standard, both p<0.001); 10 cm paramedic elevation made no difference (p=0.523)

Caveat

Simulation with manikins, not real patients

Bottom line

Context only

Learning goal

Understand how patient obesity affects my ability to achieve effective compression depth during resuscitation.

• Community CPR training only helps public arrests

  Resuscitation · 3 Sep 2026 · Registry · Hypothesis-generating

  Difference-in-differences evaluation of a year-long community hands-only CPR training initiative across 20,414 OHCAs — overall bystander CPR rates rose from 37.4% to 42.5% but the adjusted intervention effect wasn't significant (+2.94 pp, 95% CI −0.95 to 6.83); only public-location arrests showed a significant increase (+8.59 pp), with no effect at home and no detectable survival or neurological benefit.

  Resuscitation · 3 Sep 2026 · Systematic review · Hypothesis-generating

  Scoping review of 22 studies (1,254 patients, 84% OHCA) mapping intra-arrest transoesophageal echocardiography — insertion succeeded in 80–100% of cases and TEE changed management in 31–48% of patients, but the two randomised trials found no difference in ROSC, survival, or favourable neurological outcome versus conventional CPR.

  Resuscitation · 2 Sep 2026 · Cohort · Context only

  Retrospective cohort study using NEMSIS data (n=19,612) found Black patients with opioid-associated OHCA had significantly lower odds of receiving bystander CPR than White patients (AOR 0.70, 95% CI 0.63-0.77), with Hispanic patients also less likely (AOR 0.82).
