Peptic Ulcer Disease & Upper GI Bleed

Progress
Stomach factory overview
Parietal Acid and Goblet Mucus factories rely on Perfusion First for ATP and shield strength.

Safety first

O2 + glucose fuel ATP for mucus + bicarbonate shield
Oxygen and glucose make ATP that powers acid control and the mucus-bicarbonate shield.

Perfusion Pipeline: fuel before repair

??AGENT PERFUSION FIRST

"I am a endothelial cell factory. I link with tight junctions to form vessel epithelium. I deliver oxygen, glucose, electrolytes, amino acids to every downstream factory. If I slow, ATP collapses and both acid control and mucus shield fail."

???AGENT PNEUMOCYTE OXYGEN

"I am a Type I pneumocyte factory. I join neighbors to build alveolar epithelial tissue. I pass oxygen to Perfusion First so it can fuel Parietal Acid and Goblet Mucus in the stomach organ."

Chain for the patient: Steady flow builds strong ATP; strong ATP keeps the acid pump steady and the mucus thick so the lining stays protected. When flow slows, ATP drops, the pump weakens, mucus thins, the lining gets sore, and it can bleed.

Stomach factory at a glance

Same epithelial tissue, different outputs: mucus with HCO3?, HCl + intrinsic factor, pepsinogen, gastrin.

Glandular cells are epithelial cells

Quick Cue Radar

Fast map: cue, then meaning, then move.

Burning eased by food

Meaning: acid touching thin mucus.

Actions:
1) PPI/antacid per order
2) Stop NSAIDs
3) Check perfusion

Why:
Calm pump, remove irritant, restore ATP for shield.

Coffee-ground emesis

Meaning: slow upper GI bleed.

Actions:
1) Alert provider
2) Two large-bore IVs
3) Fluids; type & cross

Why:
Access and volume protect perfusion while source is treated.

Cool clammy + MAP <65

Meaning: perfusion failing.

Actions:
1) Rapid bolus
2) Hold sedatives
3) Prepare pressors if ordered

Why:
Lift MAP so factories regain ATP; avoid further drops.
