2021年6月24日 · A tension pneumothorax is a life-threatening condition caused by a pleural injury which acts as a one-way valve. As a result, air can enter the pleural space during inspiration, but is unable to escape during expiration. The accumulated air in the pleural space compresses the lungs, blood vessels, and other structures of the chest cavity.
Summary. A pneumothorax refers to an abnormal collection of air or gas in the pleural space that causes a loss of negative pressure. Like pleural effusion (liquid buildup in that space), pneumothorax may interfere with normal breathing. Pneumothorax can either be traumatic, or spontaneous. Traumatic pneumothorax occurs due to an injury to the ...
2020年11月27日 · Beck’s triad is associated with the development of acute cardiac tamponade, a medical emergency caused by the compression of the heart due to a build-up of fluid, blood, or air in the pericardial sac. The pericardial sac is a double-walled sac surrounding the heart. Normally, the pericardial sac is filled with a small amount of fluid that ...
2022年3月28日 · Obstructive shock refers to the anatomical blockage of the great vessels of the heart, leading to decreased venous return, increased afterload, and decreased cardiac output. Tension pneumothorax, pulmonary embolism, and cardiac tamponade are different causes of obstructive shock, all of which are considered medical emergencies.
2021年9月23日 · The signs and symptoms of an open pneumothorax include sudden chest pain, shortness of breath, rapid and shallow breathing, a fast heart rate, and low oxygenation of body tissues (i.e., hypoxia). Sometimes, individuals with this condition may feel weak, dizzy, restless, or agitated. An open chest wound may be visible, or a sucking sound may be ...
The pleura is the blanket that covers our lungs, and it’s made of two layers, the inner visceral pleura and the outer parietal pleura. In between those two layers is a space. If air gets in that space, it’s called a pneumothorax. Pneumothoraces can be classified into two broad categories: spontaneous or traumatic.
Pneumothorax and hemothorax are conditions that affect the pleural space surrounding the lungs. When air leaks into this space, it’s called a pneumothorax; whereas when blood fills this space, it’s called a hemothorax. Now, let’s quickly review the anatomy and physiology of the pleural space. The lungs are lined with a membrane called the ...
It extends all the way up to the clavicle and first rib, which is something that will help you understand why neck injuries can cause tension pneumothorax. Also know the inferior limit of the pleura is the 7th rib on the midclavicular line, the 10th rib on the mid axillary line, and the 12th rib on the paravertebral line.
2012年9月18日 · Needle Move Proposed for Tension Pneumothorax. Damian McNamara. September 18, 2012. September 18, 2012 — With trauma patients, it is traditional to decompress tension pneumothorax by quickly ...
2023年3月6日 · The compensatory phase of shock refers to the initial stage of shock when the body is still able to compensate for the decrease in tissue perfusion despite a loss of intravascular fluid volume or cardiac dysfunction. During the compensatory stage, compensatory mechanisms (e.g., increased heart rate, increased heart contractility, and/or ...
