HAPE：Recovery
Временное ограничение: From date of disease onset to achievement of recovery criteria ,assessed up to 36 months
|
Patients are defined as recovered only when all of the following criteria are met simultaneously: Resolution of clinical symptoms: complete relief of dyspnea (no shortness of breath at rest), disappearance of cough and expectoration, and resolution of chest tightness or chest pain. Restoration of normal physical signs: complete disappearance of lung crackles, resolution of cyanosis, and heart rate < 100 beats per minute at rest. Normalization of physiological parameters: blood oxygen saturation (SpO₂) ≥ 90% above 3500 m altitude (≥ 88% above 4000 m altitude) and normal arterial blood gas analysis (if performed). Improvement on imaging studies: clear bilateral lung fields on chest X-ray, and resolution of alveolar exudation without significant effusion on chest CT. Meeting hospital discharge criteria: stable condition for more than 48 hours, recovery of self-care ability, and no requirement for continuous oxygen therapy. |

HACE ：recovery
Временное ограничение: From date of disease onset to achievement of recovery criteria ,assessed up to 36 months
|
Patients are defined as recovered only when all of the following criteria are met simultaneously: Recovery of consciousness: Glasgow Coma Score (GCS) of 15, full restoration of orientation, and no signs of impaired consciousness. Resolution of neurological symptoms: complete relief of headache, and disappearance of ataxia, nausea, vomiting, blurred vision, and other related symptoms. Normal neurological signs: disappearance of pathological reflexes, negative meningeal irritation signs, and normal cranial nerve function. Improvement on imaging: resolution of cerebral edema, no mass effect, and normal ventricular system on head CT or MRI.
