early recognition and maintenance of airway
156
signs and symptoms of laryngeal trauma
- hoarse - pain - stridor - dyspnea - dysphagia - hemoptysis
157
airway obstruction can occur from
airway edema, laryngeal fracture, or hematoma development

164
hemoglobin
low hemoglobin results in lack of binding oxygen and CO2
165
oxygen saturation
the percentage of hemoglobin bound with oxygen, this is measured non-invasively and estimates oxygenation status
166
red blood cells
transport oxygena dn carbon dioxide, an inadequate amount of RBCs result in not enough binding material low RBCs = low Hgb = decreased transportation of oxygen and carbon dioxide
167
anemia
lack of RBCs or hemoglobin that causes insufficient oxygenation to the body
168

170

171
hypoxia
lack of oxygen in the cells
172
peak flow
vollume of air a patient can move in and out of lungs
173
respiration
movement of oxygen and CO2 across capillary and cellular membranes
174
ventilation
movement of air in and out of the lungs
175
lower airway disorders negatively impact
oxygenation, ventilation, and gas exchange which impact tissue perfusion
176
gas exchange
oxygen transport to all cells in the body and waste products of metabolism (CO2) is transported away from cells
177
gas exchaneg is acheived via
ventilation by lungs, o2 transport in blood, and perfusion via heart and vascular system
178
three mechanisms must be function for adequate gas exchange to occur
1. adequate ventilation (breathing) 2. adequate transport of o2 and co2 via RBCs w/ Hgb 3. adequate perfusion (circulation)
179
complications impacting gas exchange
1. problems with lung structure that causes difficulty in moving air in and out of alveoli (ventilation problem) 2. inability to bind and release o2 and co2 due to low RBC count or low Hgb (transport problem) 3. inability to pump oxygenated blood to cells (perfusion problem)

259
thrombolytics indicated for
massive PEs given IV or direct therapy high risk for bleeding
259
IV heparin drips are used for
moderate clots PTT levels to show proper clotting factors must perform bridging meaning to get them off drip to an oral med

common injuries occurring from chest trauma include
- flail chest - pneumothorax - hemothorax - cardiac constitution - cardiac tamponade
312
flail chest
- 3+ adjacent ribs fractured in 2+ places resulting in a free segment of ribs - result of blunt or crush chest trauma - paradoxical chest wall movement (HALLMARK SIGN) with each inhalation, the damaged area moves inward; on exhalation the chest moves outward
313
pneumothorax
reduction in negative thoracic pressure because of air in pleural space making inspiration difficult because lung cannot fully expand resulting from blunt or penetrating trauma
314
hemothorax
blood fills the pleural space, negative pressure is lost, limiting th elungs ability to expand loss of blood may result in hemodynamic compromise result of lacerated vessel from trauma
315

319
tension pneumothorax
- may occur if air or blood collects in pleural space and is not removed, the postive pressure in pleural caavity increases and the affected lung collapses - can result in compression of heart, vena cava, aorta, and contralateral affected lung - tracheal deviation toward unaffected side
320
cardiac tamponade
- excessive air, fluid, or blood collecting in pericardial sac - heart cannot adequately fill or contract because of compression of ventricles - treated with a pericardiocentesis the insertion of large bore needle into pericardial space to drain the fluid

323
subq emphysema
- air from chest injury espacing into subq space indicating potential chest trauma or chest tube not positioned appropriately - subq emphysema of head and neck could be life threatening because airway could be compromised
324
