Synchronous Respiration: Which Ventilator Rate Is Best?
Acta Paediatrica, 1987Twenty‐four infants were ventilated through a series of rates (30, 60 and 120/min), to determine which rate was most successful in provoking synchronous respiration. Their spontaneous respiratory rate was also documented during a temporary disconnection from the ventilator: respiratory rate and gestational age were significantly correlated (r=–0.85 ...

Paper sensor measures respiration rate
C&EN Global Enterprise, 2016To diagnose conditions such as sleep apnea, doctors monitor patients’ respiration rates with devices that can be cumbersome and expensive. George M. Whitesides and coworkers at Harvard University have now developed an inexpensive, lightweight paper-based alternative (Angew. Chem. Int. Ed. 2016, DOI: 10.1002/anie.201511805).

Sweat Rate Inside a Full-Facepiece Respirator
American Industrial Hygiene Association Journal, 1997The accumulation of sweat inside a full-facepiece respirator mask and the rise in facial skin temperature can be important factors for acceptability of respirators worn in the heat. This study questioned how much sweat would have to be removed from a respirator (if a design to remove accumulated sweat were possible). Results from 20 subjects sitting in

Journal of Clinical Monitoring and Computing, 2017
We tested the hypothesis that the environmental noise generated by a forced-air warming system reduces the monitoring accuracy of acoustic respiration rate (RRa). Noise levels were adjusted to 45-55, 56-65, 66-75, and 76-85 dB. Healthy participants breathed at set respiration rates (RRset) of 6, 12, and 30/min. Under each noise level at each RRset, the

Community Respiration Rates in Lake Superior
Journal of Great Lakes Research, 2004Phytoplankton photosynthesis and community respiration are two key components of the carbon cycle that determine the magnitude of net ecosystem production and the balance between oxygen production and oxygen consumption in lakes. As part of the Keweenaw Interdisciplinary Transport Experiment in Superior (KITES) project, rates of community respiration ...

REM Sleep Classification with Respiration Rates
2007 6th International Special Topic Conference on Information Technology Applications in Biomedicine, 2007Polysomnagraphy, the method evaluating the sleep quality, is the reliable and standard method. However, to perform it, subject has to attach many sensors to their body. It seems intrusive, tangled and interrupting the subjects sleep. For the sake of monitoring the daily sleep pattern, simple method measuring the biosignal nonintrusively is needed.

Respiration rates of two species of Gnathostomulids
Oecologia, 1973Respiration rates for two species of Gnathostomulida from poorly oxygenated subtidal sands of Bermuda were measured using Cartesian diver respirometers.ForHaplognathia cf.ruberrima a respiration-body weight regression gaveR=0.790·W 0,649 (in μl·10-3O2/h and μg wet weight). Respiration rates for adult animals ofGnathostomula sp.

THE CROP RESPIRATION RATE OF TULIPS
New Phytologist, 1967SummaryThe shading methods developed by Watson and Hayashi (1965) for differentiating the photo‐synthetic and respiratory components of net assimilation rate were used on a field scale for estimating the respiratory losses in a tulip crop. By selecting a period in the plant's life which may be described by a linear regression, variation due to weather ...
