Definition. Respiratory rate (also known as ventilation rate, respiration rate, breathing rate, pulmonary ventilation rate, breathing frequency, and respiratory frequency or Rf) = the number of breaths a person takes during one minute. It is usually measured at rest while sitting. Medical research ...
Through breathing, it is thus possible for us to consciously influence the heart rate to a certain extent: If we breathe deeply and in a relaxed manner, the heart rate decreases because we take in more oxygen per breath. If we breathe shallowly, not enough oxygen can be taken in with one...
A normal respiratory rate for a healthy adult is between 14 to 18 breaths a minute. In children, a normal respiratory rate...

FBM in the growth-retarded group were regular at each gestation studied and the rate was even slower than in the normal group at term, being 41.9 (1.2) at 30–33 weeks and 41.1 (1.0) at 37–40 weeks. Hyperoxia and hypercapnia aeared to have no consistent effect on fetal breathing rate...

We sought to establish normal values for the diameters of the thoracic aorta and reference curves related to body growth in children using CE-CMRA. Results CE-CMRA was performed in 53 children without cardiovascular disease. The median age was 9 years (range 2 – 20 years), weight 30 kg (...
Human heart rate is moderated by the autonomous nervous system acting predominantly through the sinus node (the main cardiac physiological pacemaker). One of the dominant factors that determine the heart rate in physiological conditions is its coupling with the respiratory rhythm. Using the language of...
Age distribution, body size and heart rate were equal between genders. Only 12/141 children were younger than 6 years [45]. Boys had larger ventricles than girls [45]. LVEF was found to be slightly higher in boys (67% vs 65%; p 0.01), but not for the RV [45]. Gender differences...
During this stage, your heartbeat and breathing all reach their lowest levels, and your muscles become as relaxed as they’ll get during the whole sleep cycle. REM sleep usually occurs about 90 minutes after you fall asleep and this stage involves an increase in your breathing, heart rate, ...
