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]
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.
Shortness of breath (SOB), known as dyspnea (in AmE) or dyspnoea (in BrE), is an uncomfortable feeling of not being able to breathe well enough. The American Thoracic Society defines it as "a subjective experience of breathing discomfort that consists of qualitatively distinct sensations that vary in intensity", and recommends evaluating dyspnea by assessing the intensity of its distinct ...
This is a list of mnemonics used in medicine and medical science, categorized and alphabetized. A mnemonic is any technique that assists the human memory with information retention or retrieval by making abstract or impersonal information more accessible and meaningful, and therefore easier to remember; many of them are acronyms or initialisms which reduce a lengthy set of terms to a single ...
If there is a valve mechanism which allows air to enter the skull but prevents it from escaping, a tension pneumocephalus can occur (similar to what can happen in a tension pneumothorax). CT scans of patients with a tension pneumocephalus typically show air that compresses the frontal lobes of the brain, which results in a tented appearance of ...
In a person with trauma presenting with pulseless electrical activity in the absence of hypovolemia and tension pneumothorax, the most likely diagnosis is cardiac tamponade. [ 26 ] In addition to the diagnostic complications afforded by the wide-ranging differential diagnosis for chest pain, diagnosis can be additionally complicated by the fact ...
These steps may happen simultaneously or depend on the most pressing concern such as a tension pneumothorax or major arterial bleed. The primary survey generally includes assessment of the cervical spine, though clearing it is often not possible until after imaging, or the person has improved. After immediate life threats are controlled, a ...
For example this paper Accidentally created tension pneumothorax in patient with primary spontaneous pneumothorax – confirmation of the experimental studies, putting into question the classical explanation says: "The widespread explanation of patophysiology of tension pneumothorax is that compression to the mediastinum by the progressively ...
