Residual gastric volume of greater than 25ml, with; pH of less than 2.5; However these are indirect measurements and are not factors that directly influence aspiration risk. [3] Patients with a high risk should have a rapid sequence induction. High risk is defined as these factors: [3] Non-elective surgical procedure
The effectiveness of the RightSpotpH® Indicator has been validated through clinical studies. A significant study published in the International Journal of Emergency Medicine demonstrated that the device is sensitive and specific for determining intragastric pH levels below or above 5.5, a common threshold used for confirming nasogastric tube placement.
Increased gastric residual may be caused by an underdeveloped gastrointestinal system that leads to slower gastric emptying or movement of the milk in the intestinal tract, reduced hormone or enzyme secretions from the gastrointestinal tract, duodenogastric reflux, formula, medications, and/or illness.

Gastric outlet obstruction (GOO) is a medical condition where there is an obstruction at the level of the pylorus, which is the outlet of the stomach. Individuals with gastric outlet obstruction will often have recurrent vomiting of food that has accumulated in the stomach, but which cannot pass into the small intestine due to the obstruction.
Gastroparesis (gastro- from Ancient Greek γαστήρ – gaster, "stomach"; and -paresis, πάρεσις – "partial paralysis") is a medical disorder of ineffective neuromuscular contractions (peristalsis) of the stomach, resulting in food and liquid remaining in the stomach for a prolonged period of time.
This avails for aspiration in one lumen, and venting in the other to reduce negative pressure and prevent gastric mucosa from being drawn into the catheter. [5] Dobhoff tube, which is a small bore NG tube with a weight at the end intended to pull it by gravity during insertion. The name "Dobhoff" refers to its inventors, surgeons Dr. Robert ...
Pulmonary aspiration is the entry of solid or liquid material such as pharyngeal secretions, food, drink, or stomach contents from the oropharynx or gastrointestinal tract, into the trachea and lungs. [1] When pulmonary aspiration occurs during eating and drinking, the aspirated material is often colloquially referred to as "going down the ...
For practical purposes, gastric pH and endoscopy should be done in someone with suspected achlorhydria. Older testing methods using fluid aspiration through a nasogastric tube can be done, but these procedures can cause significant discomfort and are less efficient ways to obtain a diagnosis.
