The volume explores the current state of knowledge on oxidants and antioxidants in disease processes, including arteriosclerosis, adult respiratory distress syndrome, cystic fibrosis, Down's syndrome, inflammation, cataract, age-related macular degeneration, afflications of the nervous system, AIDS, liver diseases, diabetes, skin diseases, and Edition: 1.

A prothrombotic coagulopathy is commonly found in critically ill COVID‐19 patients with acute respiratory distress syndrome (ARDS). A unique feature of COVID‐19 respiratory failure is a relatively preserved lung compliance and high Alveolar‐arterial oxygen gradient, with pathology reports consistently demonstrating diffuse pulmonary microthrombi on autopsy, all consistent with a vascular.

Acute respiratory distress syndrome is a form of acute respiratory failure that occurs as a complication of some other condition, is caused by a diffuse lung injury, and leads to extravascular lung fluid.

Acute respiratory distress syndrome is a type of respiratory failure characterized by rapid onset of widespread inflammation in the lungs.

Symptoms include shortness of breath, rapid breathing, and bluish skin coloration. For those who survive, a decreased quality of life is common.

Causes may include sepsis, pancreatitis, trauma, pneumonia, and aspiration. The underlying mechanism Specialty: Critical care medicine. Acute respiratory distress syndrome presents as hypoxia and bilateral pulmonary infiltrates on chest imaging in the absence of heart failure sufficient to account for this clinical state.

Since its first description, the acute respiratory distress syndrome (ARDS) has been acknowledged to be a major clinical problem in respiratory medicine. From July to July almost indexed articles were published on ARDS. This review summarises only eight of them as an arbitrary overview of clinical relevance: definition and epidemiology, risk factors, prevention and treatment.

Introduction. Chronic obstructive pulmonary disease (COPD) is a growing health problem around the world and one of the major chronic health conditions in which disability and death rates are increasing.

1 The economic burden of COPD continues to increase while new therapies are having limited impact on health-related quality of life, respiratory exacerbations or the risk of acquiring COPD. Definition. Acute respiratory distress syndrome (ARDS) is a life-threatening lung condition.

It is a form of breathing failure that can occur in very ill or severely injured people. It is not a specific disease. It starts with swelling of tissue in the lungs and build up of fluid in the tiny air sacs that transfer oxygen to the bloodstream.

This leads to low blood oxygen levels. Acute respiratory distress syndrome (ARDS) is a serious lung condition that causes low blood oxygen. People who develop ARDS are usually ill due to another disease or a major injury.

In ARDS, fluid builds up inside the tiny air sacs of the lungs, and surfactant breaks down. Most common symptoms and signs are dyspnea and hypoxemia, which progress to acute respiratory failure. Common causes are pneumonia, sepsis, aspiration, and severe trauma.

Mortality is between 40% and 50%. Low tidal volume, plateau-pressure-limited mechanical ventilation is the primary treatment t. The patient progressed from acute lung injury to acute respiratory distress syndrome (ARDS).

ARDS is a lung condition caused by trauma, sepsis, pancreatitis, aspiration, drug overdose, and massive blood transfusion.• Provide respiratory modalities including oxygen, nebulizer therapy, chest physiotherapy, endotracheal intubation or tracheostomy, mechanical ventilation, suctioning, bronchoscopy.

• Turn the patient frequently; prone position may be attempted. • Reduce anxiety by explaining all procedures and providing care in a calm, reassuring manner.
