Aotearoa e te toa! How to assess your breathing rate(Health Navigator NZ, in partnership with Northland DHB & Ministry of Health, 2022) What is your breathing rate?Your breathing rate is also known as your respiratory rate. This is the number of breaths you take per minute. Breathing rates may increase with fever, illness and other medical conditions. When checking your breathing, it's important to also note whether you have any difficulty breathing, eg, it is hard to get the air in or it hurts to breathe. Normal breathing rateNormal breathing rates for an adult person at rest range from 12–16 breaths per minute. A breathing rate under 12 or over 25 breaths per minute while resting is considered abnormal. Let our healthcare team know if you have any difficulty breathing or your rate is abnormal. How to measure your breathing rateBreathing rate is usually measured when you are at rest. It involves counting the number of breaths taken in 1 minute by counting how many times your chest rises. Take these steps to get an accurate measurement:
Note: sometimes a person's breathing rate changes because they are thinking about it or getting anxious while they are trying to measure it. If this happens, you could ask a family member to measure your breathing rate when you are not aware your breaths are being counted. References

Normal values for each of these vital signs vary by age and, in some cases, by sex. They may also vary based on weight, exercise capability, and overall health. In healthy adults at rest, normal values are as follows:
This article is about the measurement of breathing. For the parameter used in ecological and agronomical modeling, see respiration rate. The respiratory rate is the rate at which breathing occurs; it is set and controlled by the respiratory center of the brain. A person's respiratory rate is usually measured in breaths per minute. Measurement[edit]The respiratory rate in humans is measured by counting the number of breaths for one minute through counting how many times the chest rises. A fibre-optic breath rate sensor can be used for monitoring patients during a magnetic resonance imaging scan.[1] Respiration rates may increase with fever, illness, or other medical conditions.[2] Inaccuracies in respiratory measurement have been reported in the literature.[3] One study compared respiratory rate counted using a 90-second count period, to a full minute, and found significant differences in the rates.[citation needed]. Another study found that rapid respiratory rates in babies, counted using a stethoscope, were 60–80% higher than those counted from beside the cot without the aid of the stethoscope.[citation needed] Similar results are seen with animals when they are being handled and not being handled—the invasiveness of touch apparently is enough to make significant changes in breathing. Various other methods to measure respiratory rate are commonly used, including impedance pneumography,[4] and capnography which are commonly implemented in patient monitoring. In addition, novel techniques for automatically monitoring respiratory rate using wearable sensors are in development, such as estimation of respiratory rate from the electrocardiogram, photoplethysmogram, or accelerometry signals.[5][6][7][8] There are also modern applications that allow accurate respiratory rate measurement.[9] Breathing rate is often interchanged with the term breathing frequency. However, this should not be considered the frequency of breathing because realistic breathing signal is composed of many frequencies.[10] Normal range[edit]For humans, the typical respiratory rate for a healthy adult at rest is 12–15 breaths per minute.[11] The respiratory center sets the quiet respiratory rhythm at around two seconds for an inhalation and three seconds exhalation. This gives the lower of the average rate at 12 breaths per minute. Average resting respiratory rates by age are:[12][self-published source][13]
Minute volume[edit]Respiratory minute volume is the volume of air which is inhaled (inhaled minute volume) or exhaled (exhaled minute volume) from the lungs in one minute. Diagnostic value[edit]The value of respiratory rate as an indicator of potential respiratory dysfunction has been investigated but findings suggest it is of limited value. One study found that only 33% of people presenting to an emergency department with an oxygen saturation below 90% had an increased respiratory rate.[15] An evaluation of respiratory rate for the differentiation of the severity of illness in babies under 6 months found it not to be very useful. Approximately half of the babies had a respiratory rate above 50 breaths per minute, thereby questioning the value of having a "cut-off" at 50 breaths per minute as the indicator of serious respiratory illness. It has also been reported that factors such as crying, sleeping, agitation and age have a significant influence on the respiratory rate.[citation needed] As a result of these and similar studies the value of respiratory rate as an indicator of serious illness is limited. Nonetheless, respiratory rate is widely used to monitor the physiology of acutely-ill hospital patients. It is measured regularly to facilitate identification of changes in physiology along with other vital signs. This practice has been widely adopted as part of early warning systems.[16] Abnormal respiratory rates[edit]

What is an unhealthy respiratory rate?The normal respiration rate for an adult at rest is 12 to 20 breaths per minute. A respiration rate under 12 or over 25 breaths per minute while resting is considered abnormal.
What respiratory rate is too high?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.

Is respiratory rate of 20 normal?In a healthy adult, a normal respiratory rate is roughly 12 to 20 breaths per minute. Respiratory rate, one of the main vital signs of the human body, is the number of breaths taken per minute. The normal respiratory rate for adults is 12 to 20 breaths per minute.
