Respiratory Rate during Acute Asthma

Chest, 1990
Asthmatic patients hyperventilate during acute attacks, but controversy persists as to whether they breathe rapidly, deeply or both. We monitored respiratory rate under the three following conditions: (1) asthma treated in the emergency room; (2) airways obstruction provoked by methacholine inhalation; and (3) airways obstruction provoked by exercise ...

RESPIRATORY RATES IN PEDIATRIC EMERGENCY PATIENTS

Southern Medical Journal, 1990
Respiratory rates are routinely measured in pediatric emergency patients. The normal range has not been established, and commonly reported ranges seem lower than those encountered in clinical practice. This prospective study selected subjects from pediatric patients presenting for care to a suburban emergency department.

Increasing Cardiac Rate by Tracking the Respiratory Rate

Pacing and Clinical Electrophysiology, 1984
Un stimulateur asservi qui utilise la fréquence venlilatoire comme capteur a été implunté chez 22 patients, dont 19 pour la stimulation ventriculaire et 3 pour la stimulation auriculaire. Le niveau d'exercice atteint en utilisant ce système a été toiijours supérieur à celui de la stimulation ventriculaire à fréquence fixe.

Respiratory rate: the neglected vital sign

Medical Journal of Australia, 2008
The level of documentation of vital signs in many hospitals is extremely poor, and respiratory rate, in particular, is often not recorded. There is substantial evidence that an abnormal respiratory rate is a predictor of potentially serious clinical events.

Contactless portable respiratory rate monitor (CPRM) accurately measures respiratory rate in children

9.1 Respiratory Function Technologists/Scientists, 2016
Background: Respiratory rate (RR) is an important vital sign used in the initial and ongoing assessment of acutely ill children. It is also used as a predictor of serious deterioration in a patient9s clinical condition. Convenient electronic devices exist for measurement of pulse, blood pressure, oxygen saturation and temperature.

Don't Hyperventilate Over Triage Respiratory Rates

Annals of Emergency Medicine, 2013
Are triage respiratory rates inaccurate? Absolutely. In this month’s Annals, Bianchi et al compared standard nurserecorded triage respiratory rates with those measured by a research assistant during 60 seconds and those obtained by a commercial respiratory rate sensor (BioHarness; Zephyr Technology, Corp, Annapolis, MD).

Respiratory rates in emergency department patients

The Journal of Emergency Medicine, 1989
The respiratory rate is a sensitive and nonspecific indicator of respiratory dysfunction. Establishing a "normal" respiratory rate has mainly been arbitrary. This study evaluated "normal" respiratory rates in 110 emergency department patients. The mean respiratory rate was 20.1 (+/- 4.0).

Monitoring Respiratory Rate

2013
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.

Heart rate variability in subjects with different respiratory rates

Human Physiology, 2006
The 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.

Respiratory Rate as a Determinant of Optimal Pacing Rate

Pacing and Clinical Electrophysiology, 1983
Des essais ont été faits dans ľutilisation des paramètres bialogiques pour déterminer la fréquence optimale de stimulation cardiaque. Dans cette étude, le rapport entre fréquence respiratoire et fréquence cordiaque a étéétabli chez 67 patients au cours de ľexercice.
