Inflation is a method of treating respiratory diseases using a small amount of air, which is introduced into the patient's respiratory tract using special devices. Since the end of the 19th century, it has been one of the few methods used to treat asthma and chronic cough. Unlike other breathing therapy methods, such as inhaled medications (tablets, aerosols), this approach does not involve the introduction of a drug into the body, and therefore does not carry the risk of unwanted side effects from the drugs. Air inflation has improved breathing and lung activity in patients, except in rare cases where air inflation is contraindicated or too painful. During the life of people, this method of treating the respiratory system was used infrequently. This has led to a reduction in use without the need for special training for patients and medical staff. For many years, this medical procedure was put on the shelf, and only became popular again with the advent of the need to use a breathing apparatus after surgery or chest injury.
