A Process not a Form This deficiency contributed to poor end-of-life care. Act of codifies a comprehensive set of laws governing health care decision making for incompetent persons. Act creates statutorily-sanctioned methods for competent adults to provide instructions for their health care in the event of incapacity.
The alveoli Pulmonary contusion and laceration are injuries to the lung tissue. Pulmonary lacerationin which lung tissue is torn or cut, differs from pulmonary contusion in that the former involves disruption of the macroscopic architecture of the lung,  while the latter does not.
These conditions do not inherently involve damage to the lung tissue itself, but they may be associated with it.

Anyone who spends a lot of time in a vehicle is likely to experience the aches and pains that come from prolonged sitting. Long distance drivers or those that spend a lot of time driving experience pain more often as it is more difficult to shift body positions while driving.

Injuries to the chest wall are also distinct from but may be associated with lung injuries. Chest wall injuries include rib fractures and flail chestin which multiple ribs are broken so that a segment of the ribcage is detached from the rest of the chest wall and moves independently.
Signs and symptoms[ edit ] Presentation may be subtle; people with mild contusion may have no symptoms at all. Because gas exchange is impaired, signs of low blood oxygen saturationsuch as low concentrations of oxygen in arterial blood gas and cyanosis bluish color of the skin and mucous membranes are commonly associated.
Signs and symptoms take time to develop, and as many as half of cases are asymptomatic at the initial presentation. Pulmonary contusions that accompany gun and knife wounds are not usually severe enough to have a major effect on outcome;  penetrating trauma causes less widespread lung damage than does blunt trauma.
However, it is known that lung tissue can be crushed when the chest wall bends inward on impact. In the inertial effect, the lighter alveolar tissue is sheared from the heavier hilar structures, an effect similar to diffuse axonal injury in head injury. A similar mechanism may occur at the front of the lungs when the back is struck.
Fluid impairs this diffusion, resulting in less oxygenated blood bottom.
Pulmonary contusion results in bleeding and fluid leakage into lung tissue, which can become stiffened and lose its normal elasticity.
Bleeding and edema[ edit ] In contusions, torn capillaries leak fluid into the tissues around them. Fluid accumulation interferes with gas exchange,  and can cause the alveoli to fill with proteins and collapse due to edema and bleeding. Macrophagesneutrophilsand other inflammatory cells and blood components can enter the lung tissue and release factors that lead to inflammation, increasing the likelihood of respiratory failure.
Lung swelling is seen as vertical white lines, the "B-lines". Its use is still not widespread, being limited to facilities which are comfortable with its use for other applications, like pneumothorax, airway management, and hemothorax.
Accuracy has been found to be comparable to CT scanning. Airbags in combination with seat belts can protect vehicle occupants by preventing the chest from striking the interior of the vehicle during a collision, and by distributing forces involved in the crash more evenly across the body.
Positive pressure ventilationin which air is forced into the lungs, is needed when oxygenation is significantly impaired. Noninvasive positive pressure ventilation including continuous positive airway pressure CPAP and bi-level positive airway pressure BiPAPmay be used to improve oxygenation and treat atelectasis: A chest wall injury can make coughing painful, increasing the likelihood that secretions will accumulate in the airways.
Hooker showed that pulmonary contusion was an important part of the concussive injury that results from explosions. Trinkle confirmed this hypothesis in The First Aid at Work Revalidation course ensures First Aid At Work certificates are renewed and maintained.
