Respiratory rate is an early predictor of clinical deterioration in children
Pediatric Pulmonology, 2020To assess the value of respiratory rate (RR) as a predictor of clinical deterioration in children, compared with other vital sign measurements.

Respiratory Rate as an Indicator of Acute Respiratory Dysfunction
JAMA: The Journal of the American Medical Association, 1980To assess respiratory rate as an indicator of acute respiratory dysfunction, we studied 58 consecutive patients four times daily during the postoperative period. Of 825 measurements of respiratory rate, 726 (89%) were normal (24/min or less). Elevations in respiratory rate without respiratory dysfunction were found in only 4% of all measurements ...

Heart rate variability in subjects with different respiratory rates
Human Physiology, 2006The variability of the cardiac rhythm was studied in males with different initial respiratory rates. At rest and during voluntarily controlled breathing, subjects with medium respiratory rates were found to have a less variable heart rate than their counterparts with low or high respiratory rates.

The Injurious Effects of Elevated or Nonelevated Respiratory Rate during Mechanical Ventilation
American Journal of Respiratory and Critical Care Medicine, 2019Respiratory rate is one of the key variables that is set and monitored during mechanical ventilation. As part of increasing efforts to optimize mechanical ventilation, it is prudent to expand understanding of the potential harmful effects of not only ...

Efficient Respiratory Rate Extraction on a Smartwatch
2020 42nd Annual International Conference of the IEEE Engineering in Medicine & Biology Society (EMBC), 2020Using the Photoplethysmogram (PPG) sensor of a smartwatch to extract Respiratory Rate (RR) is very attractive. However, existing algorithms suffer from lack of accuracy and susceptibility to noise and movement artifacts. To tackle this issue, we propose performing Frequency Domain Peak (FDP) analysis using the Frequency Modulation (FM) feature ...

Correcting respiratory rate for the presence of fever
Journal of Clinical Epidemiology, 1994This study defines what degree of respiratory rate (RR) elevation can be attributed to fever using a double blind randomized pre- and post-acetaminophen comparison of vital signs of febrile children presenting to an outpatient clinic. Inclusion criteria were aged between 6 weeks and 24 months, fever between 38.5 and 40.1 degrees C, no serious illness ...

Respiratory recovery rates after poliomyelitis
The American Journal of Medicine, 1954Abstract Over 1,000 young adults and children have recently survived the acute stage of poliomyelitis in the United States only to be left with permanent or protracted respiratory muscle paralysis with more or less complete quadriplegia. Through realistic and timely planning much can actually be offered these severely disabled patients.

Noninvasive Measurement of Heart Rate and Respiratory Rate for Perioperative Infants
Journal of Lightwave Technology, 2019A novel fiber optic sensor is designed with mesh microbenders for simultaneous perioperative measurement of heart rate (HR) and respiratory rate (RR) for infants.

Respiratory rate is a routine vital sign recorded on all patients, in addition to pulse rate, blood pressure, and temperature. Alveolar ventilation, a product of respiratory rate and tidal volume, is very tightly controlled by receptors in the respiratory center that is found in the medulla.
