RESPIRATION AND CHEST TRAUMA Flashcards
What is a roughly hollow cylinder formed by its bony and muscular structures, lined by visceral and parietal pleura to facilitate changing intrathoracic pressure and allow inspiration of air?
Thorax
The ___ of the chest is where the trachea, pulmonary arteries and pulmonary veins are located
Hilum
What are some blood vessels of the chest?
- Great vessels
- Pulmonary vessels
- Intercostal vessels
- Internal Mammary artery
What are some different injuries of the chest?
- Blunt trauma
- Penetrating trauma
- Compression injury
These are all different kinds of what injury?
- Simple/closed pneumothorax
- Open pneumothorax
- Hemothorax
- Pulmonary Contusion
- Tracheobronchial Tree Injury
- Blunt cardiac injury
- Cardiac tamponade
- Commotio Cordis
- Traumatic Diaphragmatic Injury
- Traumatic aortic disruption
- Blunt esophageal rupture
- Tracheobronchial Disruption
Injuries of the chest
What is a lethal disruption of heart rhythm that occurs as a result of a blow to the area directly over the heart at a critical time during the cycle of the heart beat causing cardiac arrest?
Commotio Cordis
What is present in up to 20% of severe chest injuries?
Pneumothorax
What are the different types of pneumothorax?
- Simple
- Open
- Tension
What kind of pneumothorax is just the presence of air within the pleural space?
Simple pneumothorax
What kind of pneumothorax is also called a “sucking chest wound”, involves a pneumothorax associated with a defect in the chest wall that allows air to enter and exit the pleural space from the outside with ventilation effort?
Open Pneumothorax
What type of pneumothorax occurs when air continues to enter the pleural space but has no avenue for egress, resulting in increasing pressure within the pleural place, compromising circulatory function?
Tension Pneumothorax
What demonstrates finding similar to those in a rib fracture like the following?
- Chest pain
- Dyspnea
- Tachycardia
- Decreased breath sounds on affected side
- Wound may make audible suck sounds during inspiration
Simple Pneumothorax
What is the key point in the management of a simple pneumothorax?
recognition that it may become a tension pneumothorax at any time
What pneumothorax happens when a projectile enters the chest causing a small or large hole, the opening in the chest cavity allows air to enter the pleural cavity and causes the lung to collapse due to the increase in pressure in the pleural cavity?
Open pneumothorax
What chest injury presents generally in obvious respiratory distress with some of the following symptoms?
- Dyspnea
- Sudden sharp pain
- Subcutaneous emphysema
- Decreased lung sounds on the affected side
- Red bubbles on exhalation from the wound (sucking chest wound)
Open Pneumothorax
What is the initial management of an open pneumothorax?
- Closing chest wall defect
2. Supplemental O2
True or False
A casualty with an open pneumothorax rarely has an injury to the underlying lung
False
Casualty with an open pneumothorax virtually always has an injury to the underlying lung
What is the introduction of a needle or catheter into the pleural space to release trapped/accumulated air within the pleural space?
Needle thoracentesis
What is a life threatening condition where air is progressively accumulates in the pleural space, eventually compressing the lung and the mediastinum, causing decreased blood flow in the great vessels and subsequent death?
Tension Pneumothorax
Needle Decompression should be performed when what criteria are met?
- Evidence of worsening respiratory distress or difficulty with BVM device
- Decreased or absent breath sounds
- Decompensated shock (SBP <90mmHg
