The real power of this product is the internal algorithms that crunch raw data and turn it into a dashboard of health risk factors, visual event logs, and real-time alarms about baby roll-overs, sleeping position, breathing frequency, excessive fussing, sleeping patterns, and other information.
An alternative approach, which takes advantage of the fact that air moving into and out of the respiratory system creates sound (detectable as breathing frequency and sound volume) might provide an viable approach to threshold determination (Foster et al.
A special focus is on the aerodynamics of the exhalation flow and on the importance of the person's activity levels expressed as volume flow rate and breathing frequency.
The purpose of the study, according to the report, was to "measure and compare the performance of four commercially available POCs in terms of their oxygen production, purity and delivery to a simulated patient as a function of breathing frequency.
Normal subjects increase their tidal breathing up to about 50-60% of their VC, and then accomplish further increases in ventilation by increasing the breathing frequency.
The activity level and the corresponding breathing frequency of the manikins (persons) are also important.
Increased breathing frequency exacerbates DH as it limits the time for exhalation and a positive feedback cycle ensues in which DH leads to decreased IC, leading to increased breathing frequency leading to intrinsic PEEP, leading to further DH and dyspnea.
We used measurements of heart rate (HR), breathing frequency, galvanic skin response (GSR), and skin temperature.
Both CAPs-exposed groups had a significant response to the exposure, but the stress group exhibited greater breathing frequency, shorter inhalation and exhalation times, and lower expiratory flows and tidal volumes--that is, a rapid, shallow breathing pattern--compared with the nonstress group.
The yoga breathing group performed exercises designed to achieve reduced breathing frequency, slow expiration, and a pause at the end of inspiration and expiration.
Perhaps the best example in sport of where breathing frequency is naturally reduced is during front crawl swimming.
