Ultrasound of the eye is a method of diagnosing ophthalmic diseases, visualizing the structure of the eye, the condition of the ocular nerves, muscles and vessels, the lens, the retina. It is used as part of a comprehensive diagnosis of myopia, hyperopia, astigmatism, retinal dystrophy, cataract, glaucoma, eye tumors, injuries, vascular pathologies, neuritis. Several variants…
Pneumotachography (pneumotachometry) is a technique for measuring volume-velocity air flows with forced and calm breathing. The greatest diagnostic value is the determination of the flow-volume curve with forced exhalation, which allows to judge bronchial patency, to detect the presence of obstruction at preclinical stages. During the procedure, the patient breathes into a special tube with…
Body Plethysmography is a technique for studying the mechanics of external respiration: tracheobronchial resistance, extensibility of the lungs and chest, lung volumes, etc. The patient is placed in a special sealed cabin-a plethysmograph, in which he breathes through a tube communicating with the air outside the chamber. During the study, the breathing tube is closed…
Peak flow meter is a technique for measuring the maximum (peak) velocity of forced exhalation. Peak flow meter allows you to assess the degree of obstruction of the airways in COPD, bronchial asthma; determine the reversibility of bronchospasm; monitor the effectiveness of drug treatment. During the diagnosis, the patient makes the maximum possible inhalation and exhalation…
Spirometry is a functional study of the lungs, including the measurement of volumetric indicators of external respiration using a spirometer device. During the diagnosis, the lung volume (LV), minute ventilation (MV), reserve volumes of inhalation and exhalation (RO vd., RO vd.), inhalation capacity (E vd.), vital lung capacity (VC), forced vital lung capacity (FVC), maximal…
Scientists have created living robots with the ability to reproduce, that is, self-reproduction. Microscopic organisms made from frog cells may one day be used to destroy cancerous growths. A real breakthrough has been made in the field of regenerative medicine. Researchers from the University of Vermont together with colleagues from Tufts University in the USA…
A new study from the University of California has shown that the cause of Alzheimer’s disease may be breakdowns in the tau protein, which affects the stability of the cellular architecture of neurons. With age, the body loses the ability to get rid of such proteins, and this leads to the destruction of brain cells.…
A new study by American scientists suggests that adults and especially women have become more likely to experience high blood pressure during the coronavirus pandemic. This is the conclusion reached by researchers from the Cleveland Clinic. The study is based on data on 464,585 people who annually participated in various health improvement programs sponsored by…
Holly Zoccolan, a healthy lifestyle and nutrition coach, spoke about winter nutrition and the most important dietary supplements. “During the winter months, I recommend taking vitamin D, zinc and vitamin C. Vitamin D is a nutrient derived from sunlight. In the winter months, when we get less sunlight, it is better to take supplements to…
Renowned virologist and infectious disease specialist Dr. Anthony Fauci said that the COVID-19 Omicron strain may be less dangerous than the Delta variant. Therefore, the authorities are already reviewing travel restrictions to South Africa. The United States was one of the first countries in the world to impose a ban on air traffic with South…
