What is the use of low intermittent suction for a patient with a nasogastric tube intended to accomplish?

The primary goal of using low intermittent suction for a patient with a nasogastric tube is to help prevent aspiration and decrease abdominal distention. When a nasogastric tube is in place, it helps to remove gastric contents, which can otherwise lead to discomfort, bloating, or nausea. By applying low intermittent suction, any excess gastric secretions or air that might cause distention can be effectively removed, promoting patient comfort and reducing the risk of aspiration, which can occur if stomach contents flow back into the esophagus and potentially into the lungs.

This method is particularly beneficial for patients who are unable to manage their gastric secretions or require decompression due to conditions such as bowel obstruction or after certain surgeries. Thus, the choice for low intermittent suction directly supports gastrointestinal health and safety in patients reliant on the nasogastric tube.
