Slowed and irregular breathing is seen in overdoses of sleeping pills, also known as Valium, on the respiratory center, a group of nerve cells in the central nervous system that produce respiratory rhythms and regulate respiratory movements. Among the many experiments on the localization of the respiratory center, the most important one is the segmental transection of the brain stem of the cat conducted by the British physiologist Lumsden in 1923. Respiratory centers are distributed at all levels of the cerebral cortex, mesencephalon, pons, medulla oblongata and spinal cord and are involved in the generation and regulation of respiratory rhythms, which together achieve normal respiratory movements of the body). The inhibitory effect of the So, what are the symptoms that cause patients to have slowed and irregular breathing that can be easily confused with? The following is a brief introduction: 1. Mild intoxication: drowsiness, impaired judgment and orientation, unsteady gait, slurred speech, and nystagmus. Various reflexes exist, and body temperature, pulse, respiration and blood pressure are normal. 2. Moderate intoxication: shallow coma, can be awakened by strong stimulation, cannot answer questions, and soon goes into coma again. Tendon reflex disappears, breathing is shallow and slow, blood pressure is still normal, corneal reflex and pharyngeal reflex exist. 3.Severe intoxication: deep coma, increased muscle tone of the limbs in the early stage, hyperactive tendon reflexes and positive pathological reflexes. In the later stage, the whole body muscles are flaccid and various reflexes disappear. Pupil reaction to light exists, pupils are sometimes dilated and sometimes narrowed. Breathing is shallow and slow, irregular or tidal breathing. The pulse rate is fine and rapid, and the blood pressure drops.
