The RightSpotpH® Indicator is a medical device designed for verifying the correct placement of nasogastric and orogastric tubes. Developed by RightBio Metrics, this device uses pH measurement to confirm that feeding tubes are correctly positioned in the stomach, aiming to reduce risks associated with tube misplacement.
Future techniques may include measuring the concentration of enzymes such as trypsin, pepsin, and bilirubin to confirm the correct placement of the NG tube. As enzyme testing becomes more practical, allowing measurements to be taken quickly and cheaply at the bedside, this technique may be used in combination with pH testing as an effective ...
Colorimetric capnography is a qualitative measurement method that detects the presence of carbon dioxide (CO2, a relatively acidic gas) in a given gaseous environment. From a medical perspective, the method is usually applied by exposing litmus paper/film to an environment containing a patient's airway gases (i.e. placing it into their breathing circuit/airway circuit), where it will then ...
The gold standard for checking and confirming NG tube placement is to aspirate some fluid and check the pH level. The pH level of gastric secretions should be between 4-6. A secondary way to confirm placement (no longer the gold standard) is to auscultate using a stethoscope by placing the diaphragm of the stethoscope over the stomach and ...
A Miller–Abbott tube is a tube used to treat obstructions in the small intestine through intubation. [1] It was developed in 1934 by William Osler Abbott and Thomas Grier Miller . The device is around 3 metres (9.8 ft) [ 2 ] long and has a distal balloon at one end.
Percutaneous endoscopic gastrostomy (PEG) is an endoscopic medical procedure in which a tube (PEG tube) is passed into a patient's stomach through the abdominal wall, most commonly to provide a means of feeding when oral intake is not adequate (for example, because of dysphagia or sedation).
The French scale, also known as the French gauge or Charrière system, is a widely used measurement system for the size of catheters.It is commonly abbreviated as Fr but may also be abbreviated as Fg, FR or F, and less frequently as CH or Ch (referencing its inventor, Charrière).
Esophageal pH monitoring is performed for 24 or 48 hours and at the end of recording, a patient's tracing is analyzed and the results are expressed using six standard components. Of these 6 parameters, a pH score called Composite pH Score or DeMeester Score has been calculated, which is a global measure of esophageal acid exposure. A Demeester ...
