These studies suggest that lung failure symptoms include fatigue, impaired gas diffusing capacity, pulmonary hypertension, and persistent respiratory symptoms, often associated with conditions like COPD, heart failure, and acute respiratory failure.

Lung failure, whether acute or chronic, presents with a variety of symptoms that significantly impact patients' quality of life. Understanding these symptoms is crucial for timely diagnosis and effective management. This article synthesizes findings from multiple studies to provide a comprehensive overview of the symptoms associated with lung failure.
Fatigue is a prevalent and debilitating symptom in patients with chronic lung conditions such as chronic obstructive pulmonary disease (COPD) and heart failure (HF). It is described as an overwhelming sense of lethargy, lack of energy, and physical weakness that does not improve with rest and progressively worsens over time. This fatigue severely disrupts daily activities, leading to a loss of independence and social isolation. Additionally, it is often accompanied by other symptoms such as sleep disturbances, anxiety, depression, reduced appetite, and impaired cognition, which further exacerbate the condition.
Dyspnea, or shortness of breath, is a hallmark symptom of lung failure. It is commonly reported in patients with advanced COPD and heart failure. This symptom can be persistent and severe, significantly limiting physical activity and exercise tolerance . Chronic cough and sputum production are also frequent complaints, particularly in COPD patients, contributing to the overall symptom burden.
Sleep-disordered breathing, including conditions like central sleep apnea, is another significant symptom in patients with heart failure. This condition is linked to recurrent episodes of elevated pulmonary capillary pressure, leading to pulmonary edema and long-term lung damage .
Patients with advanced lung diseases often experience a cluster of symptoms, including muscle weakness, low mood, sleeplessness, and frequent micturition. Despite the high prevalence of these symptoms, they are frequently under-treated, highlighting the need for comprehensive palliative care programs that regularly assess and address these issues.
In the context of acute lung failure, such as that seen in severe COVID-19 cases, patients may experience long-term respiratory symptoms and impaired pulmonary function. These symptoms can persist for months after the initial infection, with the severity of the acute phase correlating with the degree of long-term impairment. Patients with severe disease often show significant reductions in lung function and quality of life, which may improve over time but can remain problematic for those who required intensive treatments like ECMO.
Lung ultrasound has emerged as a valuable tool for the emergency diagnosis of conditions like pneumonia, acute heart failure, and exacerbations of COPD/asthma. It offers high accuracy and can accelerate the diagnosis and management of these life-threatening conditions, thereby improving patient outcomes.
Lung failure manifests through a range of symptoms, including chronic fatigue, dyspnea, cough, and sleep-disordered breathing. These symptoms are often part of a broader cluster that includes psychological and physical comorbidities. Effective management requires a comprehensive approach that addresses all aspects of the patient's condition, including the use of diagnostic tools like lung ultrasound to facilitate timely and accurate diagnosis. Understanding and addressing these symptoms can significantly improve the quality of life for patients with lung failure.
