Introduction

Whether pulmonary bullae affect respiratory function depends on the specific circumstances. If the bullae are small and clearly asymptomatic, they may not impact respiratory function. However, larger bullae may affect respiratory function. It is recommended to seek timely medical attention and undergo treatment under a doctor's guidance. If bullae have developed and are affecting respiratory function, patients may follow medical advice to undergo lobectomy.

Whether pulmonary bullae affect respiratory function depends on the specific circumstances. If the bullae are small and clearly asymptomatic, they may not impact respiratory function. However, if the bullae are large, they might affect respiratory function. It is recommended to seek timely medical attention and receive treatment under a doctor's guidance. Detailed analysis is as follows:

If the pulmonary bullae are small and few in number, patients may experience no obvious symptoms, and the impact on respiratory function would be minimal. These patients typically do not require special treatment but should undergo regular follow-up chest CT scans.

When the bullae are large or numerous, they may compress surrounding lung tissue, leading to structural changes in the lungs and thereby affecting normal gas exchange function. This can cause patients to feel shortness of breath both during activity and at rest, and in severe cases, may require assisted ventilation therapy.

If bullae have developed and are affecting respiratory function, patients can follow medical advice to undergo lobectomy to help alleviate symptoms. It is important to rest adequately and avoid strenuous physical activity in daily life to promote recovery.

Is nebulization required for influenza A?

Under normal circumstances, "swine flu" refers to Influenza A (H1N1). Whether nebulization is needed for Influenza A (H1N1) depends on the severity of the patient's respiratory symptoms and the condition of the sputum. If symptoms are severe, affecting respiratory function, or if sputum is difficult to expel, nebulization may be required. However, if symptoms are mild and the sputum can be easily coughed up, nebulization might not be necessary. If discomfort occurs, prompt medical attention is recommended.

What is a pulmonary bulla? Is it serious?

Pulmonary bullae refer to air-filled cystic cavities formed within lung tissue due to increased pressure within alveolar spaces from various causes, leading to rupture and merging of alveolar walls. The severity of pulmonary bullae needs to be determined based on their size and associated symptoms. If the bullae are small and symptoms are mild, they are generally not considered severe; however, if the bullae are large and symptoms are significant, the condition is considered more serious.
