Pleural Effusion
Edema (pulmonary)
Sepsis (leading to Ad Resp Distress Syn)
Fibrosis (pulmonary)
____is defined as a state in which the lung, in whole or in part, is collapsed or without air. It is a condition where the alveoli are deflated, as distinct from pulmonary consolidation.

The most common cause is post-surgical atelectasis, characterized by splinting, restricted breathing after abdominal surgery. Smokers and the elderly are at an increased risk. Outside of this context, atelectasis implies some blockage of a bronchiole or bronchus, which can be within the airway (foreign body, mucus plug), from the wall (tumor, usually SCC) or compressing from the outside (tumor, lymph node, tubercle). Another cause is poor surfactant spreading during inspiration, causing an increase in surface tension which tends to collapse smaller alveoli.

3 most common causes of TBI
vehicle-related accident (>50%)
falls (25%)
violence (20%)
3 common successive stages of TBI:
Post-traumatic amnesia
An injury that causes swelling in the brain that restricts the flow of blood-borne oxygen,glucose, and other nutrients.

Brain damage characterized by microscopic damage throughout many areas of the brain. Shearing of large nerve fibers and stretching of blood vessels in many areas of the brain. The ___ and ___ lobes are particulary susceptible.
Diffuse injuries
frontal and temporal
Brain damage confined to a specific area of the brain and causing localized damage that can often be detected by CT or x-ray
Focal brain injury
Bruises that cause swelling, bleeding, and destruction of brain tissue. _____ typically affect the ____ and ___ lobes.
frontal & temporal
Cerebral or intracranial blood leak from damaged vessel in brain tissue.
Occurs in TBI when an artery to the brain is compressed by swelling of surrounding tissues, preventing flow of blood-borne oxygen to the brain.
a macroscopic area of necrotic tissue in some organ caused by loss of blood supply. Supplying arteries may be blocked from within by some obstruction (e.g. a blood clot or cholesterol deposit), or may be mechanically compressed or ruptured by trauma.

Infarctions are commonly associated with atherosclerosis, where an atherosclerotic plaque ruptures, a thrombus forms on the surface occluding the blood flow and occasionally forming an embolus that occludes other blood vessels downstream.
80% of ___ are due to infarction.
a form of traumatic brain injury in which blood collects between the dura (the outer protective covering of the brain) and the arachnoid (the middle layer of the meninges). This bleeding often separates the dura and the arachnoid layers.
Subdural hematoma

Unlike in epidural hematomas, which are usually caused by tears in arteries, subdural bleeding usually results from tears in veins that cross the subdural space. Subdural hemorrhages may cause an increase in intracranial pressure (ICP), which can cause compression of and damage to delicate brain tissue.
a buildup of blood occurring between the dura mater (the brain's tough outer membrane) and the skull. Often due to trauma, the condition is potentially deadly because the buildup of blood may increase pressure in the intracranial space and compress delicate brain tissue.
Epidural or extradural hematoma
bleeding into the subarachnoid space surrounding the brain, i.e., the area between the arachnoid membrane and the pia mater. It may arise due to trauma or spontaneously, and is a medical emergency which can lead to death or severe disability even if recognized and treated in an early stage.
subarachnoid hemorrhage
True or False

Complications from TBI can develop weeks or months after the initial injury
a condition in which abnormal accumulation of cerebrospinal fluid (CSF) in the brain causes increased intracranial pressure inside the skull. This is usually due to blockage of CSF outflow in the brain ventricles or in the subarachnoid space at the base of the brain.
A Focal brain injury characterized by an accumulation or blood or spinal fluid on the surface of the brain, exerting pressure. Symptoms of this chronic secondary complication have a slower onset than those of epidural hemorrhages because the lower pressure veins bleed more slowly than arteries. Thus, signs and symptoms may show up within 24 hours but can be delayed as much as 2 weeks
chronic subdural hematoma
3 stages of medical treatment for TBI
Stage of medical treatment wherein the patient is stabilized immediately after the TBI
Stage of medical treatment wherein the TBI patient is rehabilitated and returned to the community
Stage of medical treatment wherein the TBI patient continues rehabilitation and treats long-term impairments
