Show This is an NCLEX review for pneumothorax. Patients who have a pneumothorax are experiencing a collapse lung due to air leaking into the intrapleural space. In the previous review, I covered other respiratory disorders. So, if you are studying for NCLEX or your nursing lecture exams be sure to check out that section. When taking care of a patient with a pneumothorax it is very important the nurse knows how to recognize the typical signs and symptoms seen in this condition, how it is diagnosed, nursing interventions, and patient education. Don’t forget to take the pneumothorax quiz. In this NCLEX review for pneumothorax, you will learn the following: -Definition of pneumothorax -Pathophysiology of pneumothorax -Different types (closed, open, and tension pneumothorax) -Signs and Symptoms -Nursing Interventions Lecture on PneumothoraxPneumothorax NCLEX ReviewDefinition: 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). Learn more about lung anatomy and physiology. Key Points to Remember about Pneumothorax:
Pathophysiology of PneumothoraxThe visceral pleura (attaches to the lungs) and parietal pleura (attaches to the chest wall) are separated by a small amount of serous fluid and this space is called the intrapleural space. In a pneumothorax, this is where the air collects that causes the lung to collapse. The intrapleural space allows the visercal 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. Therefore, if air enters the intrapleural space it causes a buildup of pressure (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 chest which leads to collapse. Types of Pneumothorax to remember for the NCLEX examOpen Pneumothorax: 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 .
Closed Pneumothorax: when air leaks into the intrapleural space without any outside wound (hence the chest wall and pleural stay intact). 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:
Two classifications of Spontaneous Pneumothorax:
Tension pneumothorax: a complication of a pneumothorax (can happen with open or closed pneumothorax). This is a medical emergency. It happens when the opening to the intrapleural space creates a one-way valve…where air collects into the space but never leaves. This causes major compression on the lungs and heart. The patient will have a mediastinum shift, increased intrathoracic pressure and decreased venous return.
Signs & Symptoms of Pneumothorax:Remember the mnemonic: COLLAPSED Chest pain (sharp and sudden and worst on inspiration), Cyanosis Overt tachycardia and tachypnea Low blood pressure Low SpO2 Absent lung sounds on affected side Pushing of trachea to unaffected side (tension pneumo.) Subcutaneous emphysema (escaping carbon dioxide collecting in the skin…crunchy bulges on the skin), Sucking sound with open pneumothorax Expansion of chest rise and fall unequal Dyspnea Nursing Interventions for Pneumothorax:
