# How To Calculate Respiratory Rate From Heart Rate

The respiratory rate (RR) is the number of breaths taken per minute. The heart rate (HR) is the number of heartbeats per minute. The two are not the same but they are related.

The heart rate is affected by the respiratory rate. The faster the breathing the higher the heart rate. This is because the heart is affected by the change in pressure in the thoracic cavity during breathing.

The relationship between the respiratory rate and the heart rate is described by the respiratory sinus arrhythmia (RSA). This is the change in the heart rate that occurs with each breath.

The RSA is caused by the changing pressure in the thoracic cavity during breathing. This pressure change affects the conduction of the electrical impulses that control the heart beat.

The RSA is greatest when the breathing is slow and shallow. When the breathing is deep and fast the RSA is less.

The relationship between the respiratory rate and the heart rate can be used to calculate the respiratory rate from the heart rate.

The heart rate is usually measured in beats per minute (bpm). The respiratory rate is usually measured in breaths per minute (bpm).

To calculate the respiratory rate from the heart rate the heart rate is divided by the RSA.

For example if the heart rate is 60 bpm and the RSA is 20 the respiratory rate would be 3 breaths per minute (60/20 = 3).

The heart rate can also be affected by other factors such as exercise emotion and medications. These factors can make the heart rate go up or down.

If the heart rate is affected by another factor the respiratory rate must be adjusted accordingly. For example if the heart rate is increased by exercise the respiratory rate must be increased to maintain the same RR.

The relationship between the respiratory rate and the heart rate is important in many medical situations. It can be used to help diagnose certain conditions such as heart failure.

It can also be used to monitor the progress of a condition such as pneumonia.

The respiratory rate can also be used to help determine the appropriate dose of a medication such as an asthma inhaler.

In general a higher respiratory rate is indicative of a more serious medical condition. A lower respiratory rate is usually not a cause for concern.

There are many factors that can affect the respiratory rate. These include the depth and rate of breathing the use of accessory muscles and the presence of secretions.

The depth of breathing can be shallow normal or deep. The rate of breathing can be fast normal or slow.

Shallow breathing is usually not a cause for concern. It may be seen in normal healthy individuals when they are at rest.

Deep breathing is often seen in people with respiratory conditions such as asthma. It can also be seen in people who are exercising.

The use of accessory muscles is often seen in people with respiratory conditions such as COPD. These muscles are used to help move air into and out of the lungs.

The presence of secretions can also affect the respiratory rate. Secretions can make it more difficult to breathe and can increase the work of breathing.

The respiratory rate can be affected by many other factors including age weight gender and altitude.

Age: Infants and children have a higher respiratory rate than adults. This is because their bodies are growing and they have a higher metabolic rate.

Weight: Obesity can lead to a higher respiratory rate. This is because obese individuals have a higher body mass and a higher metabolic rate.

Gender: Females have a higher respiratory rate than males. This is because they have a higher body fat percentage and a higher metabolic rate.

Altitude:People who live at high altitudes have a higher respiratory rate. This is because the air is thinner at high altitudes and the body needs to work harder to get oxygen.

## How do you measure heart rate?

You can find your pulse on the inside of your wrist on the side of your neck or anywhere else an artery is close to the skin.
