Negative pressure pulmonary edema (NPPE) arises from airway obstruction, causing fluid buildup in lungs. Early recognition and airway management are crucial for treating this condition.
Area of Science:
- Medicine
- Pulmonology
- Critical Care
Background:
- Negative pressure pulmonary edema (NPPE) is a serious complication of upper airway obstruction.
- It can lead to severe outcomes like hypoxemia, heart failure, and shock if not managed promptly.
- Current drug treatment strategies for NPPE remain controversial.
Purpose of the Study:
- To review the etiology, clinical presentation, pathophysiology, and management of NPPE.
- To highlight diagnostic challenges and differentiate NPPE from similar conditions.
- To provide a comprehensive overview of NPPE for clinicians.
Main Methods:
- This review synthesizes existing literature on NPPE.
- It discusses the pathophysiological mechanisms, risk factors, and clinical manifestations.
- Diagnostic criteria and therapeutic interventions are analyzed.
Main Results:
- NPPE results from high inspiratory pressures during airway obstruction, increasing pleural pressure and pulmonary microvascular pressure.
- This leads to alveolar fluid accumulation.
- Laryngospasm post-anesthesia/extubation is a common cause, complicating diagnosis due to similarities with other conditions.
Conclusions:
- Effective management of NPPE relies on securing airway patency through interventions like non-invasive ventilation, oxygen therapy, or re-intubation.
- Accurate diagnosis is critical but challenging.
- Further research into optimal pharmacological treatments is warranted.

A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.
