Why the study?
Emergency physicians face high acute psychological stress during medical emergencies, but objective stress markers are difficult to measure clinically. The authors explored the relationship between heart rate variability and self-reported acute stress in residents learning intubation.
Does performing intubation alter heart rate variability as a measure of acute stress in novice airway managers?
Comparison
Before and during intubation vs resting baseline
Design
Single-center prospective study
Follow-up
1-month anesthesia rotation

HRV may track self-reported stress in EM residents; leaves open its role for real-time monitoring or intervention.
Does performing intubation alter heart rate variability as a measure of acute stress in novice airway managers?
Heart rate variability significantly decreases during intubation attempts by novice emergency medicine residents, correlating with self-reported anxiety, suggesting its utility as an objective marker of acute psychological stress.
