Physiology
The stomach protects itself from the harsh acidic environment and its own digestive enzymes through the secretion of a thick layer of mucus by mucosal cells. This mucus barrier forms a physical and chemical barrier that shields the underlying tissue from the acid and pepsin. Additionally, the stomach lining has a high turnover rate and is continuously regenerated, and the enzymes in the gastric juice are inactive until they come into contact with food.

Pulsus paradoxus is an exaggerated decrease in systolic blood pressure during inspiration, which can occur in patients with airflow obstruction conditions such as emphysema and asthma. These conditions can lead to increased intrathoracic pressure swings during respiration, which affects the cardiac output and arterial pulse amplitude.
