The accumulation of air under pressure in the pleural space. An imminent danger is that the lung will collapse under the pressure. In tension pneumothorax, what happens is that air enters the pleural cavity and is trapped there during expiration so the air pressure within the thorax mounts higher than atmospheric pressure, compresses the lung, may displace the mediastinum and its structures (including the lung) toward the opposite side, and cause cardiopulmonary impairment. Also called pressure pneumothorax,
- Tension, arterial

- Tent, oxygen
A tent-like device used to deliver high levels of oxygen to a patient in a bed. The tent typically covers the whole bed of an infant and the head and upper body of an older child or adult. The oxygen is pumped in from a tank. Oxygen is a colorless, odorless and tasteless gas that […]
- Tenth cranial nerve
The tenth cranial nerve, and one of the most important, is the vagus nerve. All twelve of the cranial nerves, the vagus nerve included, emerge from or enter the skull (the cranium), as opposed to the spinal nerves which emerge from the vertebral column. The vagus nerve originates in the medulla oblongata, a part of […]
