20.500.12556/RUL-186650 Effect of rescuer–dispatcher communication on chest compression quality during simulated cardiac arrest Background: This study aimed to assess the effects of performing chest compressions (CCs) while calling emergency medical services (EMS), compared with performing CCs without simultaneously making an EMS call, and to explore participants’ experiences during both scenarios. Methods: We conducted a mixed-methods experimental study using a within-subjects repeated-measures design in a simulated environment at the Faculty of Health Sciences, University of Ljubljana. A total of 75 healthcare students participated in the study, and each participant performed CCs in two scenarios: (1) while communicating with a dispatcher during an EMS call and (2) without makiJanng a call. CC quality was measured using the Resusci Anne Quality Cardiopulmonary Resuscitation (QC.PR) manikin (Laerdal Medical, Norway) and QCPR Learner app, with overall quality summarized using the QCPR score (0–100%). Semi-structured interviews were conducted immediately after the scenarios to explore participants’ experiences, which were divided into intrinsic and extrinsic factors. Results: In simulated cardiac arrest, CC quality was better when the rescuer was not simultaneously calling EMS. Participants’ median CC depth (65 mm vs. 70 mm; Z = −6.21, p < 0.001) and chest recoil (29% vs. 80%; Z = −5.01, p < 0.001) were reduced when participants communicated with the dispatcher. CC rate and total number of compressions remained comparable, whereas pause durations were slightly longer during the call (0.6 s vs. 0.1 s; Z = −3.09, p = 0.002). Qualitative findings revealed that participants experienced more intrinsic (such as physical and psychological strain) than extrinsic factors, which included environmental and communication-related obstacles. Conclusions: Performing CCs while talking on a smartphone with EMS reduces CC quality and increases both physical and mental effort. out-of-hospital cardiac arrest dispatcher-assisted CPR telephone CPR true false true Angleški jezik Ni določen Članek v reviji 2026-09-03 19:15:55 2026-09-03 19:15:56 2026-09-04 04:31:04 0000-00-00 00:00:00 2026 0 0 Str. 129-139 iss. 3 Vol. 22 Aug. 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2026-08-01 614.88 1845-206X 10.22514/sv.2026.032 289975299 SV2025091602.pdf SV2025091602.pdf 1 A31744E30A4E330B5222785447B41C36 1e1ebd2f3a5973b65735d227b3adb7d80ecf9760238fb71068e557daf9f5d36e 59539e89-a7bb-11f1-8bc5-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=245967 https://www.signavitae.com/articles/10.22514/sv.2026.032 1 215a4acb-a7bb-11f1-8bc5-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=245966 Zdravstvena fakulteta 0 0 0
