Key result
Slow deep breathing in healthy men demonstrated that short-term blood pressure variability (Traube-Hering waves) is formed by the interaction of respiratory sinus arrhythmia and pulse pressure modulation.
Why the study?
Blood pressure variability has become an important metric given the link between excessive blood pressure variability and adverse health outcomes.
Does slow deep breathing alter the amplitude and timing of blood pressure variability in healthy men?
Observational (n=10)

Does slow deep breathing alter the amplitude and timing of blood pressure variability in healthy men?
Answers are grounded in this paper and cite their sources.
Short-term variability of blood pressure (Traube-Hering waves) is driven by at least two independent mechanisms: respiratory sinus arrhythmia and respiratory-driven changes in pulse pressure.
Variability in blood pressure has become an important metric to consider as more is learned about the link between excessive blood pressure variability and adverse health outcomes. In this study using slow deep breathing in human subjects, we found that heart rate and pulse pressure variations have comparable effects on the amplitude of blood pressure waves, and it is the common action of the two that defines the phase relationship between respiration and blood pressure oscillations.

Barnett et al. (2020) conducted an observational in Healthy (n=10). Slow deep breathing vs. Baseline normal breathing was evaluated on Amplitude and timing of blood pressure variability with respiration (Traube-Hering waves). Slow deep breathing in healthy men demonstrated that short-term blood pressure variability (Traube-Hering waves) is formed by the interaction of respiratory sinus arrhythmia and pulse pressure modulation.
