IMMUNOLOGY

Detailed explanation-1: -Abstract. Pulmonary hypertension (PH) is a characteristic feature of the acute respiratory distress syndrome (ARDS). The magnitude of PH has been shown to correlate with the severity of lung injury in patients with ARDS independently of the severity of associated hypoxaemia and has an adverse prognostic significance.

Detailed explanation-2: -Pulmonary hypertension, or PH, occurs when blood pressure within the lungs becomes abnormally elevated. It can be caused by a thickening of the pulmonary artery walls, heart failure, lung disease (such as interstitial lung disease), and clots within the lungs’ blood vessels.
