The pH reading should be between 1-5.5. However, if you obtain a result of between 5-6 do not administer anything down the nasogastric tube. You must telephone your nurse or managing healthcare professional for further advice because the aspirate reading will need to be reconfirmed.

What should the pH of aspirate be?
Current healthcare guidelines recommend that the first-line test to confirm correct NGT placement prior to giving food or medications must be that the pH of an NGT aspirate is ≤5.5 (acidic).
What pH indicates correct tube placement?
If the pH value is 1-5.5 it suggests the tube is in the correct position (the stomach).
How do you know if NG tube is in pH of lungs?
To Check NG Tube Placement
- Attach an empty syringe to the NG tube and gently flush with air to clear the tube. Then pull back on the plunger to withdraw stomach contents.
- Empty the stomach contents on to all three squares on the pH testing paper and compare the colors with the label on the container.
What is the normal gastric pH?
The normal volume of the stomach fluid is 20 to 100 mL and the pH is acidic (1.5 to 3.5). These numbers are converted to actual acid production in units of milliequivalents per hour (mEq/hr) in some cases.
How do you measure ng pH?
Methods of confirming NG tube position
- Auscultation of air insufflated through the feeding tube (‘whoosh’ test)
- Testing the acidity/alkalinity of aspirate using blue litmus paper.
- Interpreting the absence of respiratory distress as an indicator of correct positioning.
- Monitoring bubbling at the end of the tube.
What would a gastric pH of 4 or lower indicate?
A pH of 4 has been defined as a threshold below which refluxed gastric contents become injurious to the oesophagus.
How do you know if NGT is in the lungs?
Locating the tip of the tube after passing the diaphragm in the midline and checking the length to support the tube present in the stomach are methods to confirm correct tube placement. Any deviation at the level of carina may be an indication of inadvertent placement into the lungs through the right or left bronchus.
Why do you aspirate a nasogastric tube?
Purpose of review: Aspiration is one of the most common complications in enterally fed patients. The source of aspiration is due to the accumulation of secretions in the pharynx of reflux gastric contents from the stomach into the pharynx.
How do you aspirate NG tube for pH?
Inject 30 ml of air into the tube via a 60-ml syringe immediately before pulling back on the plunger to facilitate fluid aspiration. But don’t assume the NG tube is correctly placed just because you hear a whoosh of air in the abdomen.
What pH values are basic?
As this diagram shows, pH ranges from 0 to 14, with 7 being neutral. pHs less than 7 are acidic while pHs greater than 7 are alkaline (basic).
How much do you aspirate from NG tube?
Aspirate minimum 0.5 – 1ml of gastric content (or sufficient amount to enable pH testing). Consider the “dead space” in the tubing.
What pH value should the nurse expect for small intestine secretions?
The nurse should expect to see a pH greater than 6 for respiratory and a pH of 6 or higher for the small intestine.
What are 3 complications of caring for the person with a nasogastric tube?
common complications include sinusitis, sore throat and epistaxis. more serious complications include luminal perforation, pulmonary injury, aspiration, and intracranial placement.
Can NG tube go to lungs?
While properly inserted nasogastric (NG) tubes are useful, if precautions are ignored, they can lead to several complications. These include: 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).
