Chest Injuries Flashcards
What does the Mediastinum contain?
The heart, Esophagus, trachea, and the great vessels
What does the Parietal Plura cover?
The inner chest wall
What does the Visceral Pleura cover?
Covers the lungs
Open Pneumothorax is also known as?
Sucking chest wound
Closed Pneumothorax is what and can be caused by?
Leak in lung wall and can be cause by blunt force trauma, tall men(can happen just from stretching)and athletes
How do you diagnose a Simple pneumothorax? Signs and symptoms…
Any pneumothorax not resulting in changes to cardiac physiology. Blunt trauma causing fractured ribs. Can turn into a tension
Tachypnea, crackling during palpating(subcutaneous emphysema) and decreased O2 saturation on pulse oximeter.
Tension Pneumothorax happens when? Signs and symptoms
Air accumulation in pleural space, increasing pressure in chest causing lung affected to collapse into heart decreases CO causing shock then death.
Chest pain, tachycardia, respiratory distress, absent lung sounds on affected side, JVD, cyanosis, tracheal deviation and ALOC.
What is Cardiac Tamponade? Signs and symptoms
Pericardium around heart fills with blood or fluid. Heart can’t pump enough blood
Weak(rapid) pulse, ALOC
Becks triad: JVD, muffled heart sounds, narrowing pulse pressure and hypotension
Commotion Cordis happens when? What do you need to do?
Sudden direct injury to chest during a specific part of the heartbeat electrical system.
Cardiac arrest happens causing ventricular Fib treat by(AED) D-fib and CPR
Aortic Shearing/Rupture
Laceration of great vessels, fatal hemorrhage(death likely)
What kills 1/3 of Pts. during MVC from rapid deceleration?
Aortic Shearing/Rupture
What is Paradoxical Motion and what causes it?
Move in opposite of chest during inhale, sucking on one side of chest. Happens from Flail Chest(2 fractures min on two ribs next to each other)
Cardiac contusion signs and symptoms
Can’t maintain BP, cardiac arrhythmias(irregular pulse rate, chest pain
What is Traumatic Asphyxia and what are the signs and symptoms?
Compression on chest wall, normally from compression injury(pinned)
JVD, cyanosis of face and neck(purple), bulging of the eyes.
