Slowed and irregular breathing is seen in sleeping pill overdose, sleeping pill also known as Valium, the main component is Cipro, this product white or off-white crystalline powder; odorless, taste slightly bitter. Almost insoluble in water, soluble in hydrochloric acid. It is easily hydrolyzed by acid or alkali and heat. The oral drug opens the ring under the action of gastric acid and re-cycles into the original drug when it enters the alkaline intestine. Therefore, it does not affect the bioavailability of the drug. Anti-anxiety, less compensatory rebound after discontinuation, less difficulty in discontinuation. Lighter after-effects. Large safety range. The following diseases are also etiologies that can lead to a slowed and regular respiratory rate: 1. Metabolic alkalosis Metabolic alkalosis is a clinical condition in which too much acid is lost from the body or too much base enters from outside the body, with the main biochemical manifestations being excessive blood HCO3- and increased PaCO2. pH varies according to the compensatory situation and can be significantly too high; it can also be only mildly elevated or even normal. The disease is often accompanied by low blood potassium. 2, sleep apnea syndrome Sleep apnea syndrome (SAS) refers to the continuous cessation of airflow in the mouth or nasal cavity for more than 10s and more than 30 times during 7h of sleep at night. Common causes include nasal septal deviation, nasal polyps, nasopharyngeal adenoid hypertrophy, macroglossia, tonsillar hypertrophy, mandibular malformation, chronic obstructive pulmonary disease, pulmonary heart disease, obesity dyspnea narcolepsy, acromegaly, mucinous edema, plateau erythrocytosis, pharmacological respiratory depression, and delayed medullary palliditis. Apnea can be divided into central type (no respiratory action of thoracic and abdominal muscles), obstructive type (thoracic and abdominal muscles try their best to make respiratory action) and mixed type (no respiratory action of thoracic and abdominal muscles at the beginning, and then appear and gradually strengthen), all without voluntary breathing during this period. 3, drug-induced respiratory failure (drug-induced respiratory failure, DRF) is an acute respiratory failure caused by the application of therapeutic drugs or prohibited drugs induced or promoted.
