  2. Pneumothorax - Wikipedia

    en.wikipedia.org/wiki/Pneumothorax

    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]

  3. Traumatic cardiac arrest - Wikipedia

    en.wikipedia.org/wiki/Traumatic_cardiac_arrest

    Basic life support is commonly initiated by bystanders and first responders, but the role of basic life support in traumatic cardiac arrest is unclear. Basic life support is targeted to maintain oxygenation and circulation throughout the body, which can be lifesaving in cases of medical cardiac arrest, but does not address the frequent large ...

  4. Obstructive shock - Wikipedia

    en.wikipedia.org/wiki/Obstructive_shock

    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.

  5. Traumatic asphyxia - Wikipedia

    en.wikipedia.org/wiki/Traumatic_asphyxia

    The sudden impact on the thorax causes an increase in intrathoracic pressure. [4] In order for traumatic asphyxia to occur, a Valsalva maneuver is required when the traumatic force is applied. [6]

  6. Shock (circulatory) - Wikipedia

    en.wikipedia.org/wiki/Shock_(circulatory)

    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]

  7. Tracheal deviation - Wikipedia

    en.wikipedia.org/wiki/Tracheal_deviation

    Image shows early occurrence of tracheal deviation. Tracheal deviation is a clinical sign that results from unequal intrathoracic pressure within the chest cavity.It is most commonly associated with traumatic pneumothorax, but can be caused by a number of both acute and chronic health issues, such as pneumonectomy, atelectasis, pleural effusion, fibrothorax (pleural fibrosis), or some cancers ...

  8. Pulmonary contusion - Wikipedia

    en.wikipedia.org/wiki/Pulmonary_contusion

    [27] [43] [44] The X-ray appearance of pulmonary contusion is similar to that of aspiration, [32] and the presence of hemothorax or pneumothorax may obscure the contusion on a radiograph. [25] Signs of contusion that progress after 48 hours post-injury are likely to be actually due to aspiration, pneumonia, or ARDS. [10]

  9. Signs and symptoms - Wikipedia

    en.wikipedia.org/wiki/Signs_and_symptoms

    Signs and symptoms are also applied to physiological states outside the context of disease, as for example when referring to the signs and symptoms of pregnancy, or the symptoms of dehydration. Sometimes a disease may be present without showing any signs or symptoms when it is known as being asymptomatic. [13]
