Figure Lengend Snippet: Summary of the literature review HRV: heart rate variability, HR: heart rate, VLF: very low frequency, LF: low frequency, HF: high frequency, LF/HF: low-frequency-to-high-frequency ratio, Ln LF/HF: natural logarithm of low-frequency-to-high-frequency ratio, RMSSD: root mean square of the successive differences between normal heartbeats, TP: total spectral power (overall autonomic activity), AVNN: average N-N interval, PNN50: mean number of times per time interval in which the change in the successive normal sinus (NN) intervals exceeds 50 ms, GRADE: Grades of Recommendation, Assessment, Development, and Evaluation, BP: blood pressure, PGY: postgraduate year, PTSD: post-traumatic stress disorder, D: diurnal, N: nocturnal, ASs: attending surgeons, JRs: junior residents, SRs: senior residents, HLTA: high-level trauma activation, MLTA: mid-level trauma activation, HEMS: helicopter emergency medical services, CEA: carotid endarterectomy, MWL: mental workload, AUC: area under the curve
Article Snippet: Ghazali et al., 2018 [ ] , To determine if technical and nontechnical performances correlated during immersive simulations and to quantify the physiological markers of stress (cross-sectional study) , 48 participants divided into 12 interdisciplinary teams (emergency physicians, ambulance drivers, medical residents, and registered nurses) (French National Health and Medical Research Institute) , High-fidelity simulations (pediatric patient with hypovolemic shock) , Δ PNN50, Δ LF/HF , Mean Δ PNN50 immediately before simulation-immediately after simulation: 9.0 ꝉ P < 0.0001, mean Δ LF/HF immediately before simulation-after simulation: -3.5 ꝉ P < 0.0001, ꝉ = statistically significant (P < 0.05) , Continuous electrocardiographic record (Holter analysis with the software Syncope) (Sorin Group, Clamart, France) , , Nonexperimental design, small sample size, GRADE: low.
