A normal respiratory rate for adults is between 12 to 18 breaths per minute. Normal respiratory rates for children depend on how old they are. For example, babies and toddlers take more breaths per minute than older kids and teens. Show
Your respiratory rate is the number of breaths you take in a one-minute period while at rest. Normal respiratory rates vary slightly by age and generally increase during exercise. Since a change in your respiratory rate may signal a health problem, it's important to know what the normal respiratory rate is for your age group along with how to measure yours correctly. This article covers the normal respiratory rates in adults and children. It explains how to identify when yours has changed and what that change may be telling you about your health. Verywell / Jessica OlahNormal Respiratory Rates In ChildrenChildren breathe more quickly than adults, and what's "normal" varies by age. Here's a breakdown of the rate ranges for children:
Periodic Breathing In ChildrenInfants usually have a much faster breathing rate than older children. They can also have what's called periodic breathing. With periodic breathing, a child's average respiratory rate speeds up and slows down. They may have periods during which they breathe slower than normal followed by a few minutes of breathing much faster than normal. Periodic breathing can be frightening for a parent. But it's usually normal unless your child has other symptoms of an underlying medical condition. Normal Respiratory Rate In AdultsA respiratory rate should be measured when a person is at rest, not after intense activity. In general, breathing rates are slightly faster in women than men. The average respiratory rate in a healthy adult is between 12 and 18 breaths per minute. Periodic Breathing In AdultsWhen adults have periodic swings in breathing rates, it can be a sign of a health problem. One type of periodic breathing in adults is called Cheyne-Stokes breathing, a pattern of fast, shallow breaths along with periods of no breathing or slow breathing. This type of erratic breathing is not considered normal and may be caused by:
Elderly People Normal respiratory rates in elderly people tend to be higher than those of younger adults. That's especially true among older adults in long-term care facilities. Normal Respiratory Rates During ExerciseExercise makes your muscles work harder, and in order for them to work harder, they need to use more oxygen to make more energy. The normal respiratory rate for a healthy adult is up to 18 breaths per minute at rest, but when you exercise, that rate increases to 40 to 60 breaths per minute. The increased breathing rate allows more oxygen to reach your lungs. Children also breathe faster while exercising, and they may occasionally feel mildly short of breath for a temporary time. Fast breathing that is accompanied by other symptoms like coughing or wheezing is not normal at any age, however, and should be evaluated by a healthcare professional. What the Respiratory Rate MeansThe number of breaths you take per minute is a sign of how often your brain is telling your body to breathe. If the oxygen level in the blood is low, or if the carbon dioxide level in the blood is high, your body will breathe more often. For example, having a severe infection increases the carbon dioxide produced in the body. That's true even if there's a normal level of oxygen in the blood. The brain prompts the body to breathe more often to clear the carbon dioxide. But there are times when this system doesn’t work as well. One example is when people take narcotic medications. These medications dull the brain's response to signals from the blood. That means you may breathe less often than needed. Head injuries and strokes are two more examples. Both can damage the respiratory center in the brain. Recent studies suggest that knowing your respiratory rate can help your doctor predict serious medical events. Studies also suggest that respiratory rates are not measured as often as they should be. It's been coinedthe“ignored vital sign.” Abnormal Respiratory RatesBoth higher and lower respiratory rates can be a sign that something is wrong in the body. Many different health conditions can cause either a rapid or a slow rate. Medical professionals use several terms to describe abnormal rates, including:
The rate of breathing is separate from feeling short of breath (dyspnea). Sometimes the breathing rate affects whether or not someone feels short of breath. Other times it doesn't. It's possible to feel short of breath with rapid breathing. It's also possible to have a low respiratory rate without feeling short of breath. Measuring Respiratory RateRespiratory rate is measured by counting the number of breaths a person takes in one minute. Since many factors can affect the results, it's good to understand how to measure correctly. The rate should be measured at rest, not after someone has been up and walking about. Being aware that your breaths are being counted can affect results. That's because people often change the way they breathe if they know they're being watched. One study found that rates taken when the patient knew they were being measured were around 2.13 breaths per minute slower. Nurses handle this problem by discreetly counting breaths. They watch the number of times your chest rises and falls—often while pretending to take your pulse. If you're taking a respiratory rate, look for these other signs of a breathing problem:
Increased Respiratory RateIn adults, a breathing rate over 20 breaths per minute is usually considered elevated. A rate over 24 breaths per minute indicates a very serious condition. It may be less serious when the higher rate is because of a psychological condition such as a panic attack. The respiratory rate is a very important vital sign. One study found that the respiratory rate was abetterway to determine whether someone is high riskthan heart rate or blood pressure. AdultsThere are many causes of an increased breathing rate. Some are related to the lungs and some are not. The more common causes in adults are:
NewbornsIn newborns, common causes of a rapid respiratory rate include transient tachypnea of the newborn (TTN)—a mild condition. It can also be caused by more serious problems such as respiratory distress syndrome. ChildrenIn children, the most common causes of an increased breathing rate include fever and dehydration. Some say that for every degree Celsius the body temperature rises, the breathing rate increases five to seven breaths per minute. In children less than a year old, this does not always prove to be the case. Children with a fever may not breathe faster, and vice versa. When they do have a jump in breathing rate, it usually goes up an average of seven to 11 breaths per minute per degree Celsius. Conditions such as bronchiolitis and pneumonia are common causes. Acidosis and asthma can quicken breathing rates in children, too. Decreased Respiratory RateSome experts define a low respiratory rate as less than 12 breaths a minute. Others say it's less than eight. A low breathing rate is often cause for concern. Make sure to use the rate ranges for children when you're counting a child's breaths, and use the adult ranges for adults. Some causes of a lower rate include:
When to Call Your Healthcare ProviderIf your breathing rate changes, it's a good reason to contact your healthcare provider. This is especially true if you have a condition such as asthma or heart disease. An increased respiratory rate alone can be a warning sign. If you're a healthcare professional, pay close attention to this often-ignored vital sign. One study found that measuring respiratory rate around the time of discharge from the emergency room helped to predict problems after discharge. SummaryYour respiratory rate is the number of breaths you take in one minute. Adults typically breathe at a slower rate than children. Your respiratory rate is an important measurement because many health conditions, some of them serious, can change how fast or slow you breathe. When your breathing rate changes, it may mean your body isn't getting enough oxygen. Fever, dehydration, and infection can all speed up your breathing. So can long-term health conditions like asthma, COPD, and heart problems. Alcohol, medications, sleep apnea, brain injuries, and metabolic issues can all slow your breathing. If you notice changes to your respiratory rate, talk to a healthcare professional. You may be dealing with a health condition that needs treatment. A Word From VerywellPulse and blood pressure may be the first measurements you think of when it comes to your health. But respiratory rate is just as important if not more so. When your breathing slows or speeds up, it can be a warning sign of changes in your body. It's important to know the difference between normal respiratory rates for adults and children. If you care for children, be familiar with their ranges so you can tell when their breathing is too fast or slow. Frequently Asked Questions
What heart rate is too high for a 1 year old?Tachycardia can be defined as: More than 160 beats per minute in a child less than 12 months old. More than 150 beats per minute in a child 12-24 months old. More than 140 beats per minute in a child 2-4 years old.
What is the normal RR and HR for a baby?
What does it mean when a 1 year old is breathing fast?Babies rapidly breathe when something affects their respiratory system, such as not getting enough oxygen. Doctors call rapid breathing tachypnea. When a baby exerts themselves, such as during crawling or crying, they need more oxygen, so their breathing rate may increase.
