What causes a low breathing rate?
Respiratory rate is a medical term for the number of breaths per minute, and one rise and fall of the chest is one breath, one inhalation and one exhalation. The number of breaths per minute is called respiratory rate.
Respiration is a necessary process for gas exchange between the internal and external environment of the human body. The human body inhales oxygen and exhales carbon dioxide through breathing to maintain normal physiological functions.
Low respiratory rate usually means that the respiratory rate is lower than 10 times/min. In most cases, the main reasons for the reduction of respiratory rate and respiratory movement include respiratory center depression, nerve conduction disorder, respiratory muscle weakness, etc. The details are as follows: First, respiratory center depression: carbon dioxide anesthesia can lead to respiratory center depression, resulting in a reduction and weakening of the respiratory rate.
Second, nerve conduction disorders: Central nervous system infections, trauma, tumors, and intracranial hypertension can all affect the respiratory center, resulting in a decrease in respiratory rate.
3. Weakness of respiratory muscles: There is no strength in the respiratory muscles, and the conduction of the neuromuscular is blocked, and the respiratory frequency will be reduced. Decreased movement and breathing rate. In most cases of hypoxia, the respiratory rate increases compensatively and rarely decreases. Only when the respiratory center is inhibited, the respiratory muscles have no strength, and the nerve conduction is blocked, the respiratory rate may decrease.
