The dobhoff tube goes from nose to small intestine duodenum. The nasogastric (NG) tube goes from nose to stomach.
More in-depth answer: A dobhoff tube is a small-bore feeding tube that runs from one of the nares to the stomach, then to the first part of the small intestine (duodenum). It can be advanced blindly 10 more cm to see if it can be threaded through the pyloric valve, but if it keeps coiling in the stomach, most doctors will order to place it the rest of the way under fluoroscopy. It can also be bridled in for extra security. This is mainly a feeding tube and can stay in for weeks to a few months.
An NG tube is a large-bore tube that is used for many different reasons, including decompressing the stomach for surgery and to prevent nausea/vomiting. It is NOT used for tube feedings. Usually this tube does not stay in for very long.

DevinA Dobhoff tube is a type of feeding tube that is smaller in diameter and more flexible compared to a traditional nasogastric (NG) tube. Dobhoff tubes are designed to be passed through the nose into the duodenum or jejunum, whereas NG tubes are inserted through the nose and into the stomach. Dobhoff tubes are often used for feeding patients who cannot tolerate a larger NG tube or who require feeding beyond the stomach.

Why use a dobhoff tube instead of a nasogastric tube?
A Dobhoff tube is more flexible and less likely to cause nasal trauma compared to a nasogastric tube. It is also preferred for long-term use as it can be left in place for several weeks. Additionally, a Dobhoff tube is more suitable for delivering nutrition directly into the small intestine.
What is the difference between a boiling tube and test tube?
A boiling tube is for boiling chemicals or metals, a test-tube is for holding chemical reactants. Test tubes are slimmer, boiling tubes are wide and are made of thin glass
What is the difference between a test tube and a graduated cylinder?
A test tube is a cylindrical container used for holding small amounts of liquid or solids for testing or mixing. A graduated cylinder is a tall, narrow cylinder with volume markings used to measure the volume of liquids. The main difference is that a graduated cylinder is used for precise volume measurements, while a test tube is for general purposes.
What is tube pitch?
Tube pitch refers to the center-to-center distance between adjacent tubes in a heat exchanger or a tube bundle. It plays a critical role in determining the heat transfer efficiency and pressure drop in the system. Optimal tube pitch is typically chosen based on factors such as fluid flow requirements and heat exchanger design constraints.
What is the difference between a test tube holder and a test tube rack?
A test tube holder is used to hold and carry individual test tubes securely, typically made of metal or plastic with a spring mechanism to grip the tube. A test tube rack is used to hold multiple test tubes upright and organized, often made of plastic or wood with holes to fit the test tubes.
