Respiratory rate

The respiratory rate is the rate at which breathing occurs.

The number of respiratory cycles per minute is the breathing or respiratory rate, and is one of the four primary vital signs of life.

This is usually measured in breaths per minute and is set, and controlled by the respiratory centre.

They set and maintain the rate of respiration.

It is measured regularly to facilitate identification of changes in physiology along with other vital signs.

There are four primary vital signs: body temperature, blood pressure, pulse (heart rate), and breathing rate (respiratory rate), often notated as BT, BP, HR, and RR.

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.

If both tidal volume (V T ) and respiratory rate (ƒ or RR) are known, minute volume can be calculated by multiplying the two values.

The number of breath cycles per minute is known as the respiratory rate.

The subparabrachial nucleus regulates the breathing rate.

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.

Respiration rates may increase with fever, illness, or other medical conditions.

One study compared respiratory rate counted using a 90-second count period, to a full minute, and found significant differences in the rates.. 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.

Various other methods to measure respiratory rate are commonly used, including impedance pneumography, 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 and accelerometry signals.

One study found that only 33% of people presenting to an emergency department with an oxygen saturation below 90% had an increased respiratory rate.

It has also been reported that factors such as crying, sleeping, agitation and age have a significant influence on the respiratory rate.

Hypoventilation training is a physical training method in which periods of exercise with reduced breathing frequency are interspersed with periods with normal breathing.

Hypopnea is overly shallow breathing or an abnormally low respiratory rate.

The autonomic nervous system is a control system that acts largely unconsciously and regulates bodily functions such as the heart rate, digestion, respiratory rate, pupillary response, urination, and sexual arousal.
