Invasives GI Practice Exam

The main idea is to prevent aspiration during and after bolus feeding by keeping the head of the bed elevated. A moderate incline of about 30 degrees provides a safe balance: it reduces reflux back toward the esophagus without making breathing or digestion uncomfortable. Keeping this position for 30 to 60 minutes after feeding is important because the stomach is still processing the bolus and gastric emptying can lead to residual contents that could reflux and be aspirated if the patient is flat. Elevating only during feeding or at a higher angle, or going flat after feeding, doesn’t adequately protect the airway during the vulnerable post‑meal period. Therefore, elevating the head of the bed to 30 degrees and maintaining that position for 30–60 minutes after feeding best minimizes aspiration risk.
