Introduction
In general, one can assess whether they might have "white lung" by observing the degree of shortness of breath, monitoring blood oxygen saturation, paying attention to the progression of systemic symptoms, considering underlying diseases and triggers, and undergoing imaging examinations. It is important to note that "white lung" is an imaging manifestation of severe lung lesions; self-assessment can only serve as an initial warning and cannot replace professional medical evaluation.
Generally, determining whether one has white lung can be done by observing the degree of shortness of breath, monitoring blood oxygen saturation, paying attention to the progression of systemic symptoms, considering underlying diseases and triggers, and imaging examinations. Specific analyses are as follows:
1. Assessing the Degree of Shortness of Breath
White lung often results from lung inflammation or consolidation leading to severely impaired gas exchange function, commonly presenting as significant chest tightness and rapid breathing. Even at rest, affected individuals may experience labored breathing, and in severe cases, they may be unable to lie flat, with symptoms worsening sharply upon exertion.
2. Monitoring Blood Oxygen Saturation
If home pulse oximetry consistently shows blood oxygen saturation below 93%, or if oxygen saturation fails to return to normal levels even after oxygen administration, it suggests a significant decline in pulmonary gas exchange function, indicating a possible white lung.
3. Observing Progression of Systemic Symptoms
In addition to respiratory symptoms, the presence of persistent high fever, lethargy, confusion, cold and clammy extremities, and decreased urine output—signs of systemic failure—often indicates severe lung pathology, possibly associated with white lung.
4. Considering Underlying Conditions and Triggers
If one has pre-existing conditions such as chronic obstructive pulmonary disease, asthma, diabetes, or immunocompromised status, or recent triggers such as severe lung infection or aspiration, and simultaneously exhibits the aforementioned symptoms, white lung should be highly suspected.
5. Imaging Studies
Chest CT or X-ray showing diffuse white infiltrative shadows in both lungs is the key diagnostic criterion. This appears as abnormal white lesions replacing the normal black air-filled areas of the lungs. This characteristic cannot be self-identified and must be confirmed through medical imaging.
It is important to note that white lung is an imaging manifestation of severe lung pathology. Self-assessment can only serve as an initial warning and cannot replace professional medical evaluation. If any of the above symptoms occur, especially declining blood oxygen saturation or worsening shortness of breath, immediate medical attention is necessary. Diagnosis must be confirmed through imaging studies to avoid delaying treatment for severe lung disease.
