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. So, what tests should be done for patients with symptoms of slowed and irregular breathing? The following is a brief introduction: 1, X-ray, CT examination: for dyspnea caused by cardiopulmonary disorders are obvious cardiopulmonary X-ray signs, with magnification radiography can diagnose pneumoconiosis nodules and reticular structures, body layer photography (CT) to identify the nature of the mass or look for mediastinal and hilar masses; X-ray meter wave photography to identify pericardial effusion and heart enlargement, large angiomas and tumors; bronchography to diagnose bronchiectasis, bronchial Bronchogram to diagnose bronchial dilatation, bronchial adenoma and cancer, pulmonary arteriogram to diagnose pulmonary infarction, mediastinogram and body layer photography to establish the relationship between tumor and mediastinum have diagnostic value. 2.Electrocardiogram: Patients with heart disease can have electrocardiogram, echocardiogram, late potential, cardiac function, 24h dynamic electrocardiogram, 24h dynamic hypertension and other examinations. 3.Pulmonary function test: For chronic lung diseases such as chronic bronchitis, chronic obstructive pulmonary disease (COPD), bronchial asthma, etc., do pulmonary function measurement (force spirometry FVO, force expiratory volume in one second FEVI, maximum mid-expiratory flow rate FEJ0.25~0.75, lung closed air volume measurement, residual air measurement, etc.) to diagnose the nature and degree of lung function loss. 4.Radionuclide scan of the lung: it helps to diagnose emphysema and pulmonary vascular lesions.
