Here, we present a protocol to assess two deep breathing patterns of natural and diaphragmatic breathing for their effectiveness and ease of execution. Fifteen participants were selected, utilizing an electrocardiograph and expired gas analyzer for measurement of the ventilatory parameters, together with visual assessment by video capture of thoracoabdominal movement.

The process of breathing, inhaling and exhaling, involves the coordinated movement of the chest wall, the lungs, and the muscles that move them. Two muscle groups with important roles in breathing are the diaphragm, located directly below the lungs, and the intercostal muscles, which lie between the ribs. When the diaphragm contracts, it moves downward, increasing the volume of the thoracic cavity and creating more room for the lungs to expand. When the intercostal muscles contract, the ribs...

Unrestrained barometric plethysmography is used to quantify the pattern of breathing in awake mice. We show that 15 s segments under a standardized protocol display similar values to an extended duration of quiet breathing. This methodology also allows for the quantification of apnea and augmented breaths during the first hour in the chamber.

Air-entraining Agents

Air-entraining agents improve the durability and workability of concrete in climates with frequent freezing and thawing. These agents prevent cracks by introducing small air bubbles into the mix, creating spaces accommodating water expansion when temperatures drop. The air-entraining agents lower the surface tension of water, forming stable, small air bubbles. This method is more effective than having accidental large voids, as the intentional, smaller, and evenly distributed air voids improve...

Effects of Air-entrainment in Concrete

2024
Air entrainment in concrete significantly enhances the material's durability, especially in environments subjected to freeze-thaw cycles. Introducing small air bubbles into the concrete mix acts as internal voids that accommodate the expansion of water when it freezes, thereby alleviating internal stress and preventing structural cracks. This function is crucial in climates with significant freezing and thawing, as it protects the concrete from repeated stresses that could lead to premature...
FAQs
Repeated cue-breath coupling can stabilize respiratory frequency by reinforcing the timing of inhalation and exhalation. A paced sound, visual signal, or guided count provides a temporal reference, while repetition helps the person coordinate breathing with that reference. This matters because the outcome is assessed not only by breathing frequency, but also by consistent timing.
Breathing pattern entrainment can be evaluated through respiratory rate, timing, and variability rather than through a single observation. Rate indicates how often breaths occur, timing captures the relationship between inhalation and exhalation, and variability shows how consistently the pattern is maintained. Together, these measures help determine whether coupling produced meaningful breathing control.
The source of the rhythm changes the form of the coupling. External pacing uses timed sounds, visual signals, or guided counting, whereas an internally generated physiological signal supplies the reference from within the person’s own physiology. Comparing these approaches helps researchers examine whether breathing aligns more readily with deliberate cues or another bodily rhythm.
Repetition gives the respiratory system repeated opportunities to match the same temporal structure. A single cue may influence one breath, but repeated coupling is associated with stabilization of breathing frequency and coordination with other bodily rhythms. In research or training, repeated exposure helps reveal whether breathing control becomes more stable across the observed period.
A basic session can begin by selecting a paced cue, presenting it consistently, and guiding the participant to time inhalation and exhalation to that cue. The breathing pattern is then observed or measured for rate, timing, and variability. This workflow gives clinicians or researchers a way to judge whether the intended coupling occurred and whether breathing control changed.
Applications span relaxation training, respiratory rehabilitation, sleep research, and interventions involving anxiety or autonomic regulation. In each setting, respiratory rate, timing, and variability provide a common way to evaluate the breathing response. These measurements help researchers and clinicians examine whether paced coordination supports the broader therapeutic or investigative goal.
