Pneumothorax-I01:26

Pneumothorax-I

579
A pneumothorax is a condition where air builds up in the space between the lung and the chest wall, causing the lung to collapse. This condition arises when air enters the space between the parietal and visceral pleura, disrupting the negative pressure essential for lung inflation. This can lead to a partial or complete collapse of the lung.
Pneumothorax can be even further classified as spontaneous, traumatic, and tension pneumothorax.

Pneumothorax-II01:27

Pneumothorax-II

435
Pneumothorax is a medical condition defined by the buildup of air in the pleural space between the lungs and the chest wall. This accumulation of air can lead to partial or complete lung collapse, resulting in a range of clinical manifestations. Understanding the clinical presentation and effective management strategies is crucial for healthcare professionals in providing timely and appropriate care to individuals with pneumothorax.

Pulmonary Embolism I: Introduction

162
Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...

Pleura of the Lungs01:13

Pleura of the Lungs

3.5K
The lungs are nestled in a cavity, shielded by the pleura. The pleura, a form of serous membrane, wraps around each lung. This membrane arrangement consists of two layers: the visceral and parietal pleurae. The visceral pleura lines the surface of the lungIn contrast, the parietal pleura is the outer layer and contacts to the thoracic wall, the mediastinum, and the diaphragm. The hilum is the point of connection between the visceral and parietal layers. The space between the parietal and...

Acute Respiratory Failure-III01:30

Acute Respiratory Failure-III

372
Hypercapnic respiratory failure, also known as Type 2 or ventilatory respiratory failure, is a severe condition characterized by the body's inability to effectively remove carbon dioxide (CO2) from the bloodstream. It leads to an arterial CO2 pressure (PaCO2) exceeding 45 mmHg and a blood pH above 7.35. This situation indicates that the body's ventilatory demand, or the ventilation needed to maintain normal PaCO2 levels, surpasses its supply or the maximum gas flow achievable without...

Acute Respiratory Failure-II01:21

Acute Respiratory Failure-II

417
Type I Respiratory Failure, or hypoxemic respiratory failure, occurs when the partial pressure of oxygen (PaO2) in arterial blood falls below 60 mmHg while breathing room air without a corresponding increase in arterial carbon dioxide levels (PaCO2). This condition highlights a significant impairment in the lungs' capacity to oxygenate the blood.
The underlying physiological abnormalities that contribute to hypoxemic respiratory failure include:

Area of Science:

  • Pulmonology
  • Emergency Medicine
  • Radiology

Background:

  • Spontaneous pneumothorax (SP) involves air in the pleural space, leading to lung collapse.
  • Diagnosis relies on physical examination and imaging like chest X-ray (CXR), CT, and ultrasonography.

Observation:

  • A 35-year-old male cannabis user presented with sudden, sharp right-sided chest pain.
  • The patient sought medical attention nearly 12 hours after symptom onset.

Findings:

  • A 90% pneumothorax of the right lung was diagnosed.
  • The case details symptoms, diagnostic methods, treatment, and identified risk factors.

Implications:

  • Early recognition of SP symptoms is crucial for timely intervention.
  • Cannabis use may be a potential risk factor for spontaneous pneumothorax.
  • This case underscores the importance of considering SP in young adults with chest pain.
