Researchers have found a possible link between the frequency of strokes and pollutants released into the air from the pipes of oil refineries. The work was carried out by scientists from the University of Illinois at Chicago. A new study has shown that exposure to pollutants released into the atmosphere by oil refineries can increase…
Complications of tracheal intubation are pathological conditions that occur when an intubation tube is inserted into the respiratory tract. The symptoms depend on the type of undesirable consequences. Diffuse cyanosis, barking cough, hemoptysis may occur. In the absence of timely sanitation, wheezing and gurgling can be heard at a distance. After removing the equipment, there…
Ventilator complications are the negative consequences of artificial lung ventilation that occur immediately after its onset or are the result of prolonged respiratory support. The symptoms are determined by the type of disorders. Signs of respiratory failure, emphysema, inflammatory phenomena, changes in the work of internal organs may be detected. Pathology is diagnosed on the…
Dehydration is a pathological condition that occurs when water losses exceed its intake. It is characterized by thirst, decreased diuresis, dry skin. In severe cases, symptoms such as hypotension, impaired consciousness, diffuse cyanosis are noted. Dehydration is diagnosed according to the results of a laboratory examination, which allows you to detect an increase in hematocrit indicators,…
Metabolic acidosis is a disorder of acid–base balance, which is characterized by a decrease in the concentration of bicarbonates against the background of normal or elevated acid content in plasma. The main signs are a decrease in the pH of arterial blood to the level of 7.35 and below, a deficiency of alkaline bases of…
Metabolic alkalosis is a change in the acid–base balance of the internal environment associated with the accumulation of hydroxyl anions OH- and “alkalinization” of blood. It manifests itself in the form of severe respiratory and vasomotor disorders. When the pH (hydrogen index) is shifted by more than 0.2-0.3, a comatose state occurs, by 0.4 –…
Collapse is an acutely developing vascular insufficiency, accompanied by a decrease in the tone of the bloodstream and a relative decrease in CBV. It is manifested by a sharp deterioration of the condition, dizziness, tachycardia, hypotension. In severe cases, loss of consciousness is possible. It is diagnosed on the basis of clinical data and the…
Clinical death is a reversible stage of dying that occurs at the moment of cessation of cardiac and respiratory activity. It is characterized by the absence of consciousness, pulse on the central arteries and chest excursions, dilation of the pupils. It is diagnosed according to the data obtained during the examination, palpation of the carotid…
Cardiogenic shock is an extreme manifestation of acute heart failure, characterized by a critical decrease in myocardial contractility and tissue perfusion. Symptoms of shock: falling blood pressure, tachycardia, shortness of breath, signs of centralization of blood circulation (pallor, decrease in skin temperature, the appearance of stagnant spots), impaired consciousness. The diagnosis is made on the…
Cardiogenic pulmonary edema is a pathological condition characterized by perfusion of fluid from the pulmonary vessels into the interstitial space and alveoli. It is a consequence of acute heart failure. At the initial stage of the disease, the patient is diagnosed with acrocyanosis, tachycardia, shortness of breath. As the pathology develops, white or pinkish foam…
