The aim of the present study is threefold: (i) the development of the measuring system capable of noncontact monitoring of respiratory pattern by using RGB video signal acquired from a single built-in high-definition (HD) webcam; (ii) the experimental test of this monitoring system in extracting average and breath-by-breath breathing rate values using both frequency-domain and time-domain ...

- Summary
Many factors, including age and activity levels, affect a person’s respiratory rate. Adults usually take between 12–20 breaths per minute, but children tend to breath faster.
The respiratory rate is the number of breaths someone takes every minute. It is one of the main vital signs, along with blood pressure, pulse, and temperature.
Some health issues — such as anxiety, a fever, or heart problems — can cause breathing rates to speed up.
This article looks at the normal respiratory rates in adults and children. It also discusses the causes of high or low respiratory rates and when a person should contact a doctor.
Although respiratory rates can vary slightly between individuals, there is a standard range for doctors and nurses to consider. The following table outlines normal respiratory rates based on age:
The authors of a 2022 article state that children have a higher respiratory rate than adults. Once a child reaches the age of 2, the respiration rate reduces from 44 breaths per minute to 26.
It is essential to measure a person’s respiratory rate at rest. Exercise or even walking across a room can affect it.
To take an accurate measurement, watch the person’s chest rise and fall. One complete breath comprises one inhalation when the chest rises, followed by one exhalation when the chest falls.
Breathing relies on the coordination of the control center in the brain and the respiratory muscles. An area at the base of the brain controls breathing. The brain sends signals from the brain to the breathing muscles.
Sometimes, the body needs to adjust the breathing rate. Receptors in the brain detect low oxygen or high carbon dioxide levels and send signals to the body, which can change the breathing rate.
Having an atypical respiratory rate can indicate a variety of things. In some cases, a high or low respiratory rate is due to an activity, such as exercise, and is not an indication that there is anything wrong.
Sometimes, though, various diseases, injuries, and substances can lead to a change in breathing. In a medical setting, an atypical respiratory rate, especially if it is too fast, can indicate a health problem.
Doctors refer to a high respiration rate of more than 20 breaths per minute as tachypnea.
Common causes of high respiration rates include:
•Anxiety: People may breathe faster when they are afraid or anxious. Fast breathing, or hyperventilation, is a common symptom of panic attacks. The fast breathing will usually pass once the anxiety goes away.
•Fever: As body temperature increases with a fever, respiratory rate can also increase. The increase is the body’s way of trying to get rid of the heat.
•Respiratory conditions: Conditions that can increase a person’s respiration rate include:
•chronic obstructive pulmonary disease
Doctors refer to a low respiratory rate of fewer than 12 breaths per minute as bradypnea. This can occur as a result of a worsening of an underlying respiratory condition. It can also occur as a result of airway obstructions and cardiac arrest.
Other causes include:
•Drug overdose: The use of alcohol and other depressants, such as narcotics and benzodiazepines, can depress the breathing drive in the brain, leading to low respiration rates.
•Obstructive sleep apnea: Sleep apnea involves a blockage of the airway, often due to the relaxation of the soft tissues in the throat. The blockage causes brief pauses in breathing and may decrease the overall respiratory rate.
•Head injury: Head injuries can affect the area in the brain that plays a role in breathing, which may cause a decrease in the respiration rate.

A mild variation from the typical respiratory rate may not be a cause for concern. But in some cases, a respiratory rate that is too high or too low can be a sign of a medical problem.
If the respiratory rate is atypical or a person has signs of infection such as fever, fatigue, or a sore throat, they should consult a doctor.
People with lung diseases, such as emphysema, asthma, and chronic bronchitis, may also want to contact a doctor if their respiratory rate is often atypical. It can be a sign that their lung disease is worsening.
Seek immediate assistance if any of the following is present:
•chest pain
•cyanosis, when the skin turns blue
The outlook of a person with a low or high respiratory rate depends on the underlying cause.
A normal respiratory rate varies based on age and activity levels. But various conditions, including illnesses and injuries, can also lead to a breathing rate that is too high or too low.
A person’s respiratory rate is the number of breaths they take per minute. This can vary from person to person. However, a typical breathing rate for an adult should fall between 12–20 breaths per minute. The normal breathing rate for children varies depending on their age.
A high or low respiratory rate may be a sign that an underlying issue is present. Potential causes of a high respiratory rate include anxiety, fever, respiratory diseases, heart diseases, and dehydration. Potential causes of a low respiratory rate include drug overdoses, obstructive sleep apnea, and head injuries.
If a person is experiencing an atypical breathing rate, they should contact a doctor. Seek immediate medical help if a person also has chest pain, bluish skin, gurgling sounds during breathing, or breathing very few breaths per minute.

Sep 12, 2022 · Respiration is a vital process for normal function at every level of organization from a cell to an organism; oxygen, supplied by local circulation at the tissue level, functions at the mitochondrial internal membrane as an essential mediator for energy release. In mitochondria, digested nutrients undergo metabolic reactions, end up at the level of the electron transport chain, and release ...

All the patients presented with history of cough and/or difficult breathing, on physical examination having (i) fast breathing (respiratory rate >50/min if age 2-11 months, rate >40/min if age 12-59 months) or (ii) lower chest wall in-drawing admitted in the ward and further evaluated for x-ray chest findings (mentioned in operational definition) specific for pneumonia by advising chest ...
pulse rate the rate of the pulse, measured as number of pulsations in an artery per unit of time; normally between 60 and 80 per minute in an adult. respiration rate the number of inhalations and exhalations per unit of time, usually measured by observation of chest movements and averaging 16 to 20 per minute in an adult.
Bradypnea is the medical term used to define breathing that is abnormally slow. Tachypnea is the medical term used to define an elevated respiratory rate. This rapid respiratory rate is usually shallow, versus hyperpnea which can be rapid and deep. Dyspnea refers to the sensation of shortness of breath and can occur with an elevated, a normal ...

Jan 9, 2020 · Volume 29 · Issue 1. ISSN (print): 0966-0461. ISSN (online): 2052-2819. References. This article explores the monitoring of respiratory rates in adult patients. This is a significant physical assessment skill because breathing is usually the first vital sign to alter in the deteriorating patient (Hunter and Rawlings-Anderson, 2008).
