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.
Polyurethane NG tube (Viasys Corflo), 8 Fr × 36 in (91 cm). This fine bore tube is appropriate for longer use (up to 4 weeks). Types of nasogastric tubes include: Levin catheter, which is a single lumen, small bore NG tube. It is more appropriate for administration of medication or nutrition. [5]
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 ...
For example, nasogastric (NG) tubes inserted through the nose and into the stomach can help remove stomach contents for patients who have a blockage further along in their gastrointestinal tract. After surgery, drains can be placed to remove blood, lymph, or other fluids that accumulate in the wound bed.
In and of themselves, pH indicators are usually weak acids or weak bases. The general reaction scheme of acidic pH indicators in aqueous solutions can be formulated as: HInd (aq) + H 2 O (l) ⇌ H 3 O + (aq) + Ind − (aq) where, "HInd" is the acidic form and "Ind −" is the conjugate base of the indicator. Vice versa for basic pH indicators ...
The pH range is commonly given as zero to 14, but a pH value can be less than 0 for very concentrated strong acids or greater than 14 for very concentrated strong bases. [2] The pH scale is traceable to a set of standard solutions whose pH is established by international agreement. [3]

pH meter: A potentiometer with an electrode whose potential depends on the amount of H + ion present in the solution. (This is an example of an ion-selective electrode.) The pH of the solution is measured throughout the titration, more accurately than with an indicator; at the endpoint there will be a sudden change in the measured pH.
