Abnormal breathing

The human respiratory rate is 16 to 20 beats / min for adults, and the ratio to the number of heart beats is 1: 4. The average volume of Honduras breathing at rest is 500ml (300 ~ 700ml), and the ventilation volume per minute is about 8 ~ 10l. Respiratory abnormalities are changes in the frequency of breathing, and the concept of rhythm. When the patient feels subjectively that the air is insufficient and the breathing is laborious, objectively the patient is breathing vigorously. Both the breathing muscles and the assisted breathing muscles participate in breathing movements, increased ventilation, changes in breathing frequency, depth and rhythm are called dyspnea. This is the focus of this section.
