- Adequate concentration of air
- Appropriate movement of oxygen arcoss the alveolar/capillary membrane into the aterial blood stream
- Adequate number of red bllod cells to carry oxygen
- Proper tissue perfusion
- efficant offloading of oxygen at the tissue level
Abdominal Soild organs
Abdominal Hollow organs
Three specific spaces
Peritoneal- Organs cover by abdominal (peritoneal lining
Retroperitoneal space-organs posterior to the periterior lining
Pelvic space-Organs contained within pelvis
- Increased central venous pressure (distended neck/arm veins in the presence of decreased arterial BP)
- Small quiet heart(decreased heart sounds)
seen with Pericardial tamponade
Heart is compressed by blood filling the pericardial sac.
Decreasing blood entering the heart
Blood in the pleural space
- Most comman result of major trauma
- Assoc. with great vessel or cardiac injury
- each lung can hold 2000-3000 cc of blood
Simple Pneumothorax (closed)
Air enters the pleural space causing partial lung collopse
Sucking chest wound
Wound must be 2/3 of the tracheal diameter
Affected side is exposed to atmospheric pressures= lungs collapse and shift ventilation/perfusion ratio
Buildup of pressure of air under pressure within the thorax. Results in compresion on lungs reduces effectiveness of respirations.
Can be on open or closed.
Open-Can occur when dressing sealing would does not allow air to excape during expiration.
When 3 or more consecutive ribs are boken in 2 oor more places
- Airway obstruction
- Tension pneomothorax
- Caridiac Tamponade
- Massive Hemothorax
- Open Pneomothorax
- Flail Chest
Penetrating trauma Low,Medium and High Volocity
Medium-Handguns and Shotguns
High- Assault rifles
