研究目的:

1.ARDS患者呼出气中存在哪些与ARDS发病机制密切相关的特异性成分?这些特异成分是否具有早期预警ARDS的价值? 2.ARDS患者具有何种肺部影像组学特征,以及如何运用这些影像组学特征早期诊断ARDS、预测ARDS严重程度? 3.联合应用AI影像组学分析和呼出气成分检测在早期诊断ARDS、预测ARDS严重程度方面是否存在临床应用价值?  

Objectives of Study:

1. What specific components in the exhaled breath of ARDS patients are closely related to the pathogenesis of ARDS? Do these specific components have value in early warning of ARDS? 2. What pulmonary radiomics features do ARDS patients present, and how to utilize these radiomics features for early diagnosis of ARDS and prediction of ARDS severity? 3. Does the combined application of AI-based radiomics analysis and exhaled breath component detection have clinical application value in early diagnosis of ARDS and prediction of ARDS severity?

纳入标准:

1.ARDS(柏林定义):ARDS是一种急性、弥漫性、炎症性肺损伤;其主要病理生理特征是炎症反应导致的肺微血管内皮及肺泡上皮受损,肺微血管通透性增高,肺泡腔渗出富含蛋白质的液体,进而导致肺水肿及透明膜形成。此外,还伴有肺容积减少、肺顺应性降低和严重通气/血流比例失调。 ARDS患者(柏林定义)纳入标准: (1)年龄≥18岁,性别不限; (2)急性起病(≤7天); (3)氧合障碍(需在PEEP≥5 cmH?O条件评估) 轻度:PaO?/FiO? 200-300 mmHg; 中度:PaO?/FiO? 100-200 mmHg; 重度:PaO?/FiO? ≤100 mmHg。 (4)胸片或CT显示双肺浸润影且无法完全用胸腔积液、肺不张或结节解释。 2.ARDS患者(2023全球新定义)纳入标准: (1)年龄≥18岁,性别不限; (2)急性起病(≤7天); (3)胸片/CT显示双侧肺部透亮度减低;肺部超声见双侧B线和/或实变,不能用积液、肺不张或结节/肿块解释。 (4)低氧血症:采用脉搏氧饱和度(SpO2)替代动脉氧分压(PaO2)用于评估氧合状况,同时需要满足SpO2≤97%。当SpO2≤97%时,可用SpO2/FiO2判定低氧血症及ARDS严重程度分级: 轻度:235 mmHg<SpO2/FiO2≤315 mmHg; 中度:148 mmHg<SpO2/FiO2≤235 mmHg; 重度:SpO2/FiO2≤148 mmHg; (5)特定类型: 插管ARDS:与柏林定义基本一致。 非插管ARDS:指接受高流量鼻导管氧疗(HFNC)≥30L/min或无创正压通气/持续气道正压通气时呼气末正压(PEEP)至少5cmH2O,且满足ARDS低氧血症标准者。 资源有限环境下的ARDS:在资源有限情况下,SpO2/FiO2≤315mmHg同时SpO2≤97%即可诊断,不要求特定的呼吸支持设备、最低氧流量或呼气末正压。 3.健康志愿者纳入标准: (1)年龄≥18岁,性别不限; (2)无肺部疾病史。 (3)血常规、血生化、凝血功能、心电图、胸部X线等常规检查均未发现异常;

Inclusion criteria

1. ARDS (Berlin Definition): ARDS is an acute, diffuse, inflammatory lung injury; its main pathophysiological features include damage to pulmonary microvascular endothelium and alveolar epithelium caused by inflammatory responses, increased pulmonary microvascular permeability, exudation of protein-rich fluid into alveolar spaces, which further leads to pulmonary edema and hyaline membrane formation. In addition, it is accompanied by reduced lung volume, decreased lung compliance, and severe ventilation/perfusion mismatch. Inclusion criteria for ARDS patients (Berlin Definition): (1) Aged >= 18 years, regardless of gender; (2) Acute onset (<= 7 days); (3) Oxygenation impairment (to be evaluated under the condition of PEEP >= 5 cmH?O) - Mild: PaO?/FiO? 200–300 mmHg; - Moderate: PaO?/FiO? 100–200 mmHg; - Severe: PaO?/FiO? <= 100 mmHg. (4) Chest X-ray or CT shows bilateral pulmonary infiltrates that cannot be fully explained by pleural effusion, atelectasis, or nodules. 2.Inclusion criteria for ARDS patients (2023 Global New Definition): (1) Aged >= 18 years, regardless of gender; (2) Acute onset (<= 7 days); (3) Chest X-ray/CT shows bilateral reduced lung opacity; lung ultrasound shows bilateral B-lines and/or consolidation, which cannot be explained by effusion, atelectasis, or nodules/masses. (4) Hypoxemia: Pulse oxygen saturation (SpO?) is used instead of arterial oxygen partial pressure (PaO?) to evaluate oxygenation status, and SpO? <= 97% must be met. When SpO? <= 97%, SpO?/FiO? can be used to determine hypoxemia and ARDS severity grading: Mild: 235 mmHg < SpO?/FiO? <= 315 mmHg; Moderate: 148 mmHg < SpO?/FiO? <= 235 mmHg; Severe: SpO?/FiO? <= 148 mmHg; (5) Specific types: Intubated ARDS: Basically consistent with the Berlin Definition. Non-intubated ARDS: Refers to patients receiving high-flow nasal cannula oxygen therapy (HFNC) >= 30 L/min or non-invasive positive pressure ventilation/continuous positive airway pressure with positive end-expiratory pressure (PEEP) of at least 5 cmH?O, and meeting the ARDS hypoxemia criteria. ARDS in resource-limited settings: In resource-limited situations, a diagnosis can be made if SpO?/FiO? <= 315 mmHg and SpO? <= 97% simultaneously, without requiring specific respiratory support equipment, minimum oxygen flow, or positive end-expiratory pressure. 3.Inclusion criteria for healthy volunteers: (1) Aged >= 18 years, regardless of gender; (2) No history of lung diseases. (3) No abnormalities found in routine examinations such as blood routine, blood biochemistry, coagulation function, electrocardiogram (ECG), and chest X-ray;
