Resp refers to people's breathing frequency per minute, and the normal situation should be about 15 to 20 breaths per minute.

If the respiratory rate is not within the normal range at the time of physical examination, further examination is needed. Especially for the elderly, the examination of resp during physical examination is the most common examination, because it is an important diagnostic basis.

Basic definition: chest fluctuation is a breath, that is, an inhalation and an exhalation. The number of breaths per minute is called breathing frequency.

Detection method: When calculating the breathing frequency, we should closely observe the chest of the subject, record the breathing times of the subject for half a minute with a clock with a second hand, and then multiply the measured times by 2 to get the breathing times per minute, that is, the breathing frequency.

Introduction: Breathing times per minute. Respiratory frequency varies with age, sex and physiological state. The breathing frequency of adults at rest is about 12-20 times per minute; Children are about 20 times per minute; Generally, women are faster than men 1-2 times. It is also an important diagnostic basis for doctors in clinical diagnosis.

Normal adults breathe about 12-20 times per minute. The ratio of respiration to pulse is 1: 4, that is, the pulse beats 4 times every 1 breath. Children breathe faster than adults, up to 20 ~ 30 times per minute; The newborn's breathing frequency can reach 44 times per minute. In the resting state, the breathing frequency of normal adults is 12 ~ 18 beats/min, and the ratio of breathing to pulse is 1: 4. Newborns breathe about 44 times per minute, which gradually slows down with age. The main manifestations of peripheral respiratory failure.

1, shortness of breath (tachypnea) means that the breathing frequency exceeds 24 times/minute. It exists in fever, pain, anemia, hyperthyroidism and heart failure. Generally, the body temperature rises by 65438 0℃, and breathing increases by about 4 times per minute.

2. Slow breathing means that the breathing frequency is lower than 12 beats/min. Shallow and slow breathing is seen in excessive anesthetics or sedatives and increased intracranial pressure.

3. The breathing frequency changes with the depth of breathing, and the breathing is shallow, which is found in respiratory muscle paralysis, severe bulging, ascites and obesity, as well as lung diseases such as pneumonia, pleurisy, pleural effusion and pneumothorax. Breathing is deep and fast during strenuous exercise, because the increase of oxygen supply in the body requires an increase in lung gas exchange.

In addition, when you are emotional or overly nervous, you often take deep breaths and hyperventilate. At this time, the partial pressure of carbon dioxide in arterial blood decreases, causing respiratory alkalosis. Patients often feel numb around the mouth and limbs, and in severe cases, they may have tetany and apnea. When severe metabolic acidosis occurs, there will be deep and slow breathing. Due to the lack of bicarbonate in extracellular fluid, the pH value decreases and carbon monoxide is excreted through the lungs. , compensation, to regulate extracellular acid-base balance, seen in diabetic ketosis and uremic acidosis. This kind of deep breathing is also called Cusmore breathing.
