In contrast, tension pneumothorax is a medical emergency and may be treated before imaging – especially if there is severe hypoxia, very low blood pressure, or an impaired level of consciousness. In tension pneumothorax, X-rays are sometimes required if there is doubt about the anatomical location of the pneumothorax. [16] [18]
Obstructive shock may be due to cardiac tamponade or a tension pneumothorax. [1] Distributive shock may be due to sepsis, anaphylaxis, injury to the upper spinal cord, or certain overdoses. [1] [4] The diagnosis is generally based on a combination of symptoms, physical examination, and laboratory tests. [2]
Left-sided tension pneumothorax. Note the area without lung markings which is air in the pleural space. Also note the tracheal and mediastinal shift from the patient's left to right. Causes include any obstruction of blood flow to and from the heart. There are multiple, including pulmonary embolism, cardiac tamponade, and tension pneumothorax.
Others, like reduced oxygen tension at high altitude, may be regionally distributed or associated with a specific demographic. [8] Generalized hypoxia is an occupational hazard in several high-risk occupations, including firefighting, professional diving, mining and underground rescue, and flying at high altitudes in unpressurised aircraft.
According to the Pew Research Center, 27% of U.S. adults age 60 and over live alone, compared with 16% of their peers in the 130 countries and territories studied.Despite pushback from their adult ...
Barotrauma is physical damage to body tissues caused by a difference in pressure between a gas space inside, or in contact with, the body and the surrounding gas or liquid. [1] [2] The initial damage is usually due to over-stretching the tissues in tension or shear, either directly by an expansion of the gas in the closed space or by pressure difference hydrostatically transmitted through the ...
Typically, dementia is associated with classic symptoms like confusion and memory loss. But new research finds that there could be a less obvious risk factor out there: your cholesterol levels ...
Of people with pulmonary contusion alone, 17% develop ARDS, while 78% of people with at least two additional injuries develop the condition. [6] A larger contusion is associated with an increased risk. In one study, 82% of people with 20% or more of the lung volume affected developed ARDS, while only 22% of people with less than 20% did so. [7]
