Tension pneumothorax occurs when the opening that allows air to enter the pleural space functions as a one-way valve, allowing more air to enter with every breath but none to escape. The body compensates by increasing the respiratory rate and tidal volume (size of each breath), worsening the problem.
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.
Left tension pneumothorax with a large, well-demarcated area devoid of lung markings with tracheal deviation and movement of the heart away from the affected side. Mediastinal shift is an abnormal movement of the mediastinal structures toward one side of the chest cavity .
Pneumothorax Condition; A person breathing at rest inhales and exhales approximately half a liter of air during each respiratory cycle, which is called tidal volume. The respiratory rate is directly affected by the concentration of carbon dioxide in the blood. Lungs do not collapse after forceful respiration because of the residual volume.

Untreated tension pneumothorax is an absolute contraindication. [7] IMPLEMENTATION When treating atelectasis - Therapy should be volume-oriented; 2. Tidal volumes(VT) must be measured 3. VT goals must be set 4. VT goal of 10-15mL/kg ofbody weight 5. Pressure can be increased to reach VT goal if tolerated by patient.
Signs of serious chest injuries, including penetrating trauma to the chest, which can cause a sucking chest wound; flail chest; tension pneumothorax; and cardiac tamponade; Breathing problems (like airway problems, these are also rechecked during the rapid trauma assessment by listening to breath sounds with a stethoscope)
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 ...
