What is the frequency of breathing? To what extent is the index normal?

Breathing is an important activity to sustain life. Because this is the process of oxygen supply to the brain and other bodies of the body. When breathing frequency is affected by pathology or risk factors can be very beneficial to humans, can even be life-threatening.

1. What is the frequency of breathing?

Breathing frequency (breathing rate) is the measure of the number of breaths in a minute. The frequency of breathing is conditioned and controlled by the respiratory center. General principles for monitoring breathing frequencies:

  • The measuring subject should be rested before entering the measurement for about 15 minutes.
  • Subjects before measuring breathing frequency do not use respiratory stimulants or injections or other activities that affect breathing.
  • Follow proper technical procedures and breathing monitoring commands.
  • The measurement results are recorded accurately, clearly.

Measure breathing frequency in about 15 minutes

2. Indicators of normal breathing frequency

Normal breathing will have characteristics such as: regular, soothing respiratory process, slow and deep air through the nose.

Normal breathing frequency in adults is 16-20 times/min, breathing rate is even, breathing amplitas are average, breathing is strong and exhalation time is short.

Normal breathing frequency in children will be divided by month of age/ age:

  • Infant: 40 – 60 times/min
  • Children under 6 months of age: 35 – 40 times/min
  • Children 7 – 12 months: 30 – 35 times /min
  • Children from 2 to 3 years old: 25 – 30 times /min
  • Children from 4 to 6 years old: 20 – 25 times / minute
  • Children from 7 to 15 years old: 18 -20 times/min

3. Changes in breathing frequency

3.1. Changes in the well-being

That change in breathing is a change in normal, healthy people. Breathing will increase rapidly due to having to breathe faster and deeper than usual. This change is common in cases: after labor, practice physical exercise, it is hot, hot,… On the contrary, slow breathing will be encountered in some people thanks to the practice of physical exercise, air conditioning, so the breathing rate will be slower than in the average person.

3.2. Changes in pathology

In the case of pathology, the breathing rate will change both the frequency of breathing, the amplitasity of breathing. This is shortness of breath. Symptoms of shortness of breath are common but sometimes it is difficult to diagnose and treat, especially in patients with an emergency difficulty breathing. When dealing with emergency cases of shortness of breath, doctors should note the potentially life-threatening causes of patients such as: airway obstruction, cardiovascular diseases, respiratory diseases …

Cheyne-Stokes breathing: Common in patients with brain haemorrhage, brain tumors, intoxication. It is characterized by shortness of breath and serial rotational apnea. In a one-minute cycle:

  • At 1, 1 will stop breathing for about 15-20 seconds due to the respiration center's breast;
  • In, 2 will start with shallow, light breathing, slowly and then become fast, deep and strong. It then turns into a gentle breathing, then stops and begins a new breathing cycle. This process makes high levels of carbon dioxide accumulated in the blood and stimulates the respiratory center.

Kussmaul breathing: Commonly seen in diabetic coma. It is characterized by deep inhalation, short apnea and rapid exhalation.

If you have shortness of breath, you should be given airway through airway evaluation and control. The doctor will then select the technique depending on the patient's specific condition to conduct airway opening, such as in-administration, Heimlich test, oxygen breathing, and artificial ventilation.
