That is usually the journal article where the information was first stated. In most cases Physiopedia articles are a secondary source and so should not be used as references. Physiopedia articles are best used to find the original sources of information (see the references list at the bottom of the article). If you believe that this Physiopedia article is the primary source for the information you are refering to, you can use the button below to access a related citation statement. Introduction[edit | edit source]Respiratory rate (RR) is a non–invasive and useful assessment tool and abnormalities in respiratory rate have been shown to indicate patient deterioration and should be managed accordingly.[1] Respiration is a vital process for humans, supplying oxygen to the mitochondria for ATP production (our bodies energy currency). The main byproduct of this process, carbon dioxide which goes through a process to finally be exhaled form our lungs. The respiratory rate, i.e., the number of breaths per minute, is highly regulated to enable cells to produce the optimum amount of energy at any given occasion.
Image 1: Animation of a diaphragm exhaling and inhaling Norms - Respiratory Rates[edit | edit source]RR is measured by counting the number of breaths a person takes in a one-minute period. The rate should be measured at rest, not after someone has been up and walking about.
Recent evidence suggests that an adult with a respiratory rate of over 20 breaths/minute is probably unwell, and an adult with a respiratory rate of over 24 breaths/minute is likely to be critically ill.[3] Best Practice Procedure[edit | edit source]Points to remember:
Importance[edit | edit source]Changes and anomalies in RR are not simply associated with respiratory conditions, they are a good indicator that a patient is struggling to maintain homeostasis. Respiratory rate is an early, extremely good indicator of physiological conditions such as hypoxia (low levels of oxygen in the cells), hypercapnia (high levels of carbon dioxide in the bloodstream), metabolic and respiratory acidosis. Conditions in altered RR include:
Image 2: Researchers at University College London have developed new algorithms that make it possible to use low-cost thermal cameras attached to mobile phones to track how fast a person is breathing. This type of mobile thermal imaging could be used for monitoring breathing problems in elderly people living alone, people suspected of having sleep apnea or babies at risk for sudden infant death syndrome (SIDS). Terminology[edit | edit source]Terms to describe abnormal respiratory rate include:

Why is monitoring respiratory rate important?Respiratory rate is a fundamental vital sign that is sensitive to different pathological conditions (e.g., adverse cardiac events, pneumonia, and clinical deterioration) and stressors, including emotional stress, cognitive load, heat, cold, physical effort, and exercise-induced fatigue.
Why is recording the results of pulse respiratory rate important in health care?Respiratory rate assessment has many uses such as: to monitor fluctuations in a patient's condition or recognize acute changes, to indicate signs of deterioration and to recognize the need for treatment escalation [8].
Why is respiratory rate important to cardiovascular endurance?Breathing rate increases to provide the body (exercising muscles) with oxygen at a higher rate. Heart rate increases to deliver the oxygen (and glucose) to the respiring muscles more efficiently. The heart, lungs and circulatory system working together make up the cardiovascular system.
What is respiratory rate monitoring?Your respiratory rate is also known as your breathing rate. This is the number of breaths you take per minute. You can measure your breathing rate by counting the number of breaths you take over the course of one minute while you're at rest. To get an accurate measurement: Sit down and try to relax.
