Ph of peg
WebPEG per se does not modify pH of aqueous solution. When partly deteriorated due to oxidation it may lower pH. In your case increase in pH is due to alkaline catalyst. Cite 3 … WebSo, a pH of less than 5.0 would be most accurate in showing the tube is in the correct position. The study also evaluated the use of a pepsin assay in predicting proper tube placement.4 Pepsin levels are much higher in gastric aspirate than tracheal aspirate but, unfortunately, are not practical for bedside use.

WebApr 8, 2024 · Measuring the pH of gastric aspirate is considered the 'gold standard' in routine confirmation of NG tube placement prior to use. Typically, a pH of <6 would indicate an NG tube is in the stomach. See this previous Connected Care QuickHit for best practice for confirming placement of NG tubes. PEG and related polymers (PEG phospholipid constructs) are often sonicated when used in biomedical applications. However, as reported by Murali et al., PEG is very sensitive to sonolytic degradation and PEG degradation products can be toxic to mammalian cells.
