Pneumothorax is a potentially life-threatening condition, a principal diagnosis that emergency medical services (EMS) providers must promptly identify. The most common symptoms of this condition are acute, unilateral chest pain and shortness of breath. Pneumothorax can affect all age groups. Thus, EMS providers should maintain a high index of suspicion for this condition for any patient with sudden-onset unilateral chest pain and respiratory distress. This activity is designed to enhance learners' competence in identifying pneumothorax in the prehospital setting. Valuable insights will be gained to improve learners' skills in working with an interprofessional team caring for patients affected by this condition. Objectives: Identify the clinical manifestations indicative of pneumothorax, encompassing subjective complaints and pertinent physical indicators associated with this pathological condition. Compare the therapeutic modalities available for the management of pneumothorax within the prehospital environment. Apply point-of-care ultrasound as a rapid and efficient diagnostic modality for evaluating patients suspected of having pneumothorax. Collaborate with an interprofessional healthcare team in planning and executing a comprehensive pneumothorax management strategy. Access free multiple choice questions on this topic.

Prehospital providers are responsible for identifying and treating various conditions that may need rapid intervention. Pneumothorax is one potentially life-threatening condition that may be quickly identified with high-quality physical examination skills. The condition develops when air accumulates in the pleural space, causing partial or complete lung collapse. Continuous air accumulation can increase intrathoracic pressure. Tension pneumothorax arises when intrathoracic air pressure is high enough to shift mediastinal contents contralaterally. Up to 1 in 20 major trauma patients develop tension pneumothorax.[1] Treating pneumothorax can be relatively simple, though complications like cardiac or major blood vessel injury can occur.[2] Identifying this condition in the prehospital setting is challenging. Unlike the resource-rich emergency department, prehospital providers cannot rely on imaging studies or thoracic surgery consultation when evaluating individuals with a possible pneumothorax (see Image. Left Pneumothorax on X-ray). Additionally, comorbid conditions like chronic obstructive pulmonary disease (COPD), asthma, congestive heart failure, and pleural effusion can mimic a pneumothorax clinically. Understanding the nuances in the clinical presentation of this condition can improve prehospital diagnostic accuracy and time to initial intervention.

Lung auscultation must be performed after needle decompression to reassess the patient. Needle decompression is only a temporizing measure. Chest tube placement is still necessary upon arrival at the emergency department. Possible treatment complications include worsening pneumothorax, bleeding, infection, and lung parenchymal damage. Most prehospital providers are confident in their ability to perform needle decompression. However, a study found that only approximately one-third of prehospital decompression catheters are correctly placed within the pleural cavity, and up to 20% of procedures are not medically indicated. Incorrectly placed needles may damage surrounding vasculature or solid organs, including the heart. Individuals with a simple, spontaneous pneumothorax who were simply provided oxygen treatment must be observed for 3 to 6 hours. Longer observation periods are warranted for patients with more complex pneumothoraces. Recurrence may occur after pneumothorax treatment, especially at high altitudes or deep sea. Therefore, patients must be advised to avoid air travel or diving for 7 to 14 days after treatment.[26]

Pneumothorax management is best approached interprofessionally. The members of this team include the following: EMS personnel: providers who are often the first responders, crucial in recognizing potential pneumothorax in the prehospital setting and providing initial treatment. Emergency physicians: responsible for confirming the diagnosis of pneumothorax, often using ancillary imaging modalities such as chest x-rays or CT. Emergency physicians may perform chest tube insertion and initiate referrals to surgeons and pulmonologists for co-management. Radiologists: interpret imaging studies, provide detailed assessments of pneumothorax severity, and offer insights into potential complications. Pulmonologists: provide treatment for the underlying medical causes of pneumothorax. Respiratory therapists: assist in managing patients' respiratory status, ensuring adequate oxygenation, and collaborating with the team in implementing appropriate ventilatory support if necessary. General or thoracic surgeons: may provide expertise in surgical repair of persistent or recurrent pneumothoraces. Nurses: play a critical role in continuous patient monitoring, administering medications, and providing supportive care. Pharmacists: ensure appropriate medication management and address potential drug interactions or contraindications in the context of pneumothorax management. Rehabilitation specialists: physical and occupational therapists help patients optimize their functional capacity after pneumothorax resolution. Effective communication, collaboration, and a clear delineation of roles within the interprofessional team are essential for providing optimal care to patients with pneumothorax.[27][28]
