Ch.34 Flashcards
Cardiac contusion
Is a common cardiac injury following severe blunt trauma to the chest
Commotio cordis
Sudden cardiac arrest from blunt fore applied to the precordial area of the anterior chest
Crepitation
A granting sound or sensation
Diaphragm
The thoracic cavity is bordered inferior lay by
Flail segment
Segment of chest that is unattached to the rest of the rib cage
Hemoptysis
Coughing up blood or bloodstained sputum
Hemopneumothorax
Which is the collection of both blood and air in lungs
Hemothorax
The thoracic cavity filled with blood rather than air
Intercostal muscles
Muscles between the ribs
Jugular vein distention JVD
is an indication of possible cardiac injury or tension pneumothorax
Kussmaul sign
Increase in venous pressure
Mediastinum
A hallow area is the middle of the thoracic cavity between the right and left lungs
Open pneumothorax
Result of an open wound to the chest created by a penetrating object
Paradoxical movement
Flail segment may not exhibit paradoxical chest wall movement
Parietal pleura
Lungs Outermost layer and in contact with thoracic wall
Pericardial tamponade
Blood flow into the right side of the heart flows against greater resistance the venous pressure increases causing distention of the jugular veins
Pneumothorax
Pressure on the lung so the lungs collapses and leads to
Potential space
Between the pleural layers
Pulmonary contusion
Bleeding within the lung tissue
Pulses paradoxus
Drop in systolic blood pressure during inhalation is referred to as
Subcutaneous emphysema
Air trapped under the skin giving it a bubbly inflated appearance and a crackling feel when palpated
Sucking chest wound
An open chest wound can pull air into the thoracic cavity sometimes with a noticeable sucking sound
Tension pneumothorax
That is caused by air leaking into the chest cavity from a damaged lung with no opening through the outer chest
Thoracic cavity
Chest cavity
Traumatic asphyxia
Occurs when severe and sudden compression of the thorax causes a rapid increase in the pressure of the chest
Tracheal deviation
The trachea moves toward the side of the uninjured lung
Visceral pleura
Innermost layer and is in contact with the lung
