What is the blue piece on an NG tube?
An anti-reflux valve is attached to the blue pigtail to prevent gastric contents from seeping out.
What is the purpose of the sump lumen on an NG tube?
Salem-sump: is a two-lumen nasogastric/orogastric tube. The dual lumen tube allows for safer continuous and intermittent gastric suctioning. The large lumen allows for easy suction of gastric contents, decompression, irrigation and medication delivery.
What is Salem sump?
Salem sump tube a double-lumen nasogastric tube used for suction and irrigation of the stomach. One lumen is attached to suction for the drainage of gastric contents and the second lumen is an air vent.
What is the purpose of an anti reflux valve and what consequences occur when one is not present on a Salem sump ‘?
The anti-reflux valve prevents stomach contents from exiting the vent lumen. This prevents unnecessary patient gown and bedding changes and reduces the risk of exposure to potentially infectious materials.
What is the difference between Salem sump and Levin tube?
The Levin tube is a one-lumen nasogastric tube. The Salem-sump nasogastric tube is a two-lumen piece of equipment; that is, it has two tubes. The Levin tube is usually made of plastic with several drainage holes near the gastric end of the tube.
What is a cantor tube?
Cantor Tube. This is a 10-foot long, single-lumen tube used for intestinal decompression. The Cantor tube has a mercury-weighted rubber tab attached to its perforated tip to help carry the tube through the stomach and intestine.
What is the difference between a Levin tube and a Salem sump tube?
What is anti reflux valve?
How can you prevent aspiration when removing an NG tube?
Instruct patient to take a deep breath and hold it. This prevents aspiration; holding the breath closes the glottis. 10. Kink the NG tube near the naris and gently pull out tube in a swift, steady motion, wrapping it in your hand as it is being pulled out.
What is a Lopez Valve used for?
The Lopez Valve is designed to help you save time by eliminating the use of nasogastric (NG) tube plugs and poor syringe connections while keeping you safe from accidental exposure to infectious bodily fluids.
How often should a Lopez Valve be changed?
Critical care nurses might consider changing Lopez valves at intervals of 14 days or less and perhaps at each tubing change (or per facility policy).
What is Cantor tube?
What type of suction is used for NG tube?
When using for suction, intermittent suction is used to prevent the tube from adhering to the gut wall. Prolonged use of these tubes may result in stiffening of the tube which may increase risk of perforation.
Can Salem sump be used for feeding?
At that time, Salem Sump nasogastric tubes were a reasonable choice for enteral nutrition because they have an air vent to facilitate gastric aspiration, and enteral feeding can be provided through the tube when suction is not being applied.
What is the best position to prevent aspiration?
Body positions that minimize aspiration include the reclining position, chin down, head rotation, side inclination, the recumbent position, and combinations of these. Patients with severe dysphagia often use a 30° reclining position.
What happens if NG tube is in lungs?
The tube may enter the lungs Because of the proximity of the larynx to the oesophagus, the nasogastric tube may enter the larynx and trachea (Lo et al, 2008). This may cause a pneumothorax (Zausig et al, 2008). When the tube is in the airway, it will cause severe irritation and cough.
What is the normal reflux index for a nasogastric tube?
With maximum 100 mm Hg abdominal pressure, the reflux index was control, 1.75 +/- 0.45%; small-bore tube, 1.67 +/- 0.28%; and large-bore tube, 1.88 +/- 0.35% (NS). The reflux index was not different between small-bore and large-bore nasogastric tubes.
What are the different types of nasogastric (NG) tubes?
A total of 11 subjects were studied three times: control, no nasogastric tube, small-bore (8F) nasogastric tube, and large-bore (14F) nasogastric tube.
How is reflux assessed in patients with gastroesophageal reflux disease?
Reflux was assessed by gastroesophageal scintiscanning, a radioisotopic technique that detects and quantitates GE reflux. A total of 11 subjects were studied three times: control, no nasogastric tube, small-bore (8F) nasogastric tube, and large-bore (14F) nasogastric tube.
Does nasogastric tube size affect pulmonary aspiration of gastric contents?
Pulmonary aspiration of gastric contents results initially from reflux of stomach contents into the esophagus. Small-bore enteral feeding tubes are thought to result in less pulmonary aspiration and less reflux. We prospectively investigated the effect of nasogastric tube size upon gastroesophageal …
