Duoneb is part of the group of anti-asthma drugs used in the form of inhalations. The main active components of the drug are ipratropium bromide and albuterol. Ipratropium bromide is a quaternary ammonium compound that has anticholinergic properties. It is a competitive antagonist of such a neurotransmitter as acetylcholine. Ipratropium bromide produces a blocking effect…

Sputum is mucus that is produced in the lungs and respiratory tract. It is important to prevent microbes from entering the airways and lungs. Usually, it is transparent and thin, completely invisible. However, when an infection appears, the mucus can thicken and change color. Therefore, depending on the disease, the mucus of different colors may…

Pulmonary artery catheter (Swan-Ganz catheter, PA catheter) is a catheter used in medicine to evaluate central hemodynamic parameters. What does it look like? The pulmonary catheter in the classic version is a four-lumen catheter with four “tails”: a venous (proximal) port, a temperature sensor connector, a balloon port and a pulmonary (distal) port. Depending on…

Lateral chest X-ray is a diagnostic method that uses x-rays and allows getting an image of the internal organs, blood vessels and lymphatic system of the chest, as well as the ribs and spine of the chest. Today, modern x-ray equipment is used, which allows a 5-fold reduction in the radiation dose compared to traditional…

Hypoxia (Greek – “little oxygen”) is the state of oxygen starvation of the whole organism and individual organs and tissues caused by various external and internal factors. Causes of hypoxia Hypoxic (exogenous) – a decrease in the oxygen content in the inhaled air (stuffy unventilated rooms, high altitude conditions, high-altitude flight without oxygen equipment); Respiratory…

SIMV stands for “synchronized intermittent (periodic) forced ventilation” of the lungs. The regimen is mainly used in patients with at least a small number of stable independent attempts at inspiration. Sedative therapy is minimized so as not to depress spontaneous breathing. It is fundamentally important to choose the trigger sensitivity correctly so that the fan recognizes most…

Minute Ventilation

Lung volume and vital capacity of the lungs are static characteristics measured in one respiratory cycle. But oxygen consumption and the formation of carbon dioxide occur in the body continuously. Therefore, the constancy of the gas composition of arterial blood depends not on the characteristics of one respiratory cycle but on the rate of oxygen…

Mandatory Minute Ventilation (MMV) is a fan action mode in which all breaths are forced and delivered by a fan with a given frequency (f), volume or pressure, and inspiration time. In the proposed list of modes, MMV covers all methods that deliver only forced or a combination of forced and auxiliary breaths. The only…

Sepsis is a dangerous disease that develops when an infection enters the bloodstream. As a result, a systemic inflammatory reaction develops that encompasses the entire body and affects vital organs What is sepsis? Translated from the Greek language, sepsis means “decay”. The people often call the disease “blood poisoning.” However, the Greek definition better explains…

What is Airway Resistance?

Category: Health Care
October 7, 2019lung diseaselungsrespiratory system

Airway resistance is the resistance to the flow of air through the respiratory tract during inhalation and expiration. When air goes into the lungs, gas molecules meet resistance, as they hit the walls of the airways. Therefore, the diameter of the airways affects resistance. Resistance will increase if the diameter of the bronchioles decreases. When the…
