Pneumothorax Flashcards
the collapsing of a lung due to air accumulating in the pleural space (the space between the visceral and parietal pleura which is also called the intrapleural space).
Pneumothorax
___________ tubes & pneumothorax go hand in hand
chest tubes
Key Points to Remember about Pneumothorax:
It can be a partial or __________ collapse of the lung (mainly affects one lung).
Causes include but not limited to: ____________ (without warning), trauma to the _________ (blunt or penetrating), lung disease, medical procedures (central line placement, mechanical ventilation).
It is diagnosed with a chest x-ray, ultrasound, or CT scan.
A ____________pneumothorax usually resolves on its own.
A __________ pneumothorax usually requires treatment like a ___________ to remove air from intrapleural space or needle aspiration (as with a tension pneumothorax).
total; spontaneous; chest; small; large; chest tube
Attached to the chest wall is the ________ pleura
parietal
Attached to the lungs is the _______________ pleura ?
Visceral
What is within the intrapleural space and what does it do ?
Small amounts of serous fluid are between the parietal and visceral pleura. In a pneumothorax, this is where the air collects that causes the lung to collapse.
The intrapleural space allows the visceral and parietal pleura to glide over one another during inhalation and exhalation which creates a negative pressure. The negative pressure acts like suction to keep the lungs inflated.
In pneumothorax, the lung gets pushed away from the ____________
chest wall
Therefore, if air enters the____________ space it causes a buildup of ____________ (remember under normal condition the lungs like negative pressure) which decreases the ability of the lungs to recoil and pushes the lung away from the ___________ which leads to _________
intrapleural; pressure; chest; collapse
What kind of pneumothorax is this ?
an opening in the chest wall (from a gun shot, stabbing etc.) that causes a passage between outside air and the intrapleural space. This allows air to pass back and forth during inspiration and expiration. Therefore, the body will shunt air through the chest wall opening instead of the trachea .
Open pneumothorax
This type of pneumothorax is also known as a sucking chest wound ?
Open pneumothorax ………….
Remember, normally you have air passing through trachea (not the chest wall) to the lungs while breathing. Because of this you may hear a “sucking sound” This type of pneumothorax is also known as a sucking chest wound.
Remember, normally you have air passing through ___________ (not the chest wall) to the lungs while breathing.
trachea
In an open pneumothorax, you may hear a “sucking sound” because of the air passing through the chest wall. This type of pneumothorax is also known as a sucking chest wound.
Nursing intervention for an open chest wound ?
place a sterile occlusive dressing over the opening and tape it on 3 sides (leaving the 4th side free from tape). This prevents the wound from being occluded. This type of dressing will allow exhaled air to leave the opening but seal over the opening when inhaling (hence preventing a tension pneumothorax).
This is when air leaks into the intrapleural space without any outside wound. (hence the chest wall and pleural stay intact)
What can cause this ?
Closed Pneumothorax
Example of what can cause this: a rib fracture where the sharp, bony part of the bone punctures the lung causing air to be released into the intrapleural space. Another common cause of closed pneumothorax is called spontaneous pneumothorax
What is a spontaneous pneumothorax?
a defect in the alveolar wall and visceral pleura where air enters into the intrapleural space. An example: pulmonary bleb (sac-like blister that develops on the visceral pleura that ruptures and leaks air into the pleural space). This causes pressure to build up in the intrapleural space and causes the lung to collapse. It known as a “spontaneous” pneumothorax because the pneumothorax was NOT caused by an injury.
Patients can have multiple pulmonary blebs and they don’t have to rupture immediately. Exact cause of rupture is not totally understood but things that can increase the rupture of a bleb include: change in air pressure, taking a sudden, deep breath, or smoking
Why is a spontaneous pneumothorax known as “spontaneous”?
Because the pneumothorax was not caused by an injury
