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 tests do patients need to do when they have symptoms of slowed and irregular breathing? The following is a brief introduction: 1, blood routine: in the case of infection there is an increase in the white blood cell count, neutrophils increased, allergic diseases or parasitic diseases, eosinophil count increased. 2.Urinary routine: positive urine sugar, positive urine ketone body in diabetic patients; positive urine protein, tubular type and red and white blood cells in uremic disease. 3.Blood biochemistry: increased blood glucose and decreased carbon dioxide binding in diabetic patients; increased blood urea ammonia and blood creatinine in uremic syndrome. 4, sputum examination: bronchial – lung disease should pay attention to the volume, nature and smell of sputum and do bacterial culture, fungal culture, sputum to find tuberculosis bacteria, sputum pathology to find cancer cells, etc. all have some diagnostic value.
