Confirm NG/OG Tube Placement with RightSpotpH®

The ONLY FDA Cleared, CLIA waived products that use pH for confirming gastric acidity for tubes intended to end in the stomach. Fully closed system that helps protect clinicians and patients from exposure to aspirate. Indicated for neonates, pediatrics and adults.



pH is the emerging US/Global Standard for confirming NG/OG tube gastric placement in the NICU.


Emergency Department

Faster and much less expensive than x-ray, immediate results and no exposure to radiation.



Immediate confirmation of gastric acidity, without exposure to x-ray.


General Use

Versatile, can be used in hospital or home environment to confirm tube placement without exposure to x-ray.

Our Mission: Eliminate any harm caused by misplaced NG/OG tubes.

“As a physician who has lost patients to misplaced NG tubes when a nurse used an inaccurate method to verify placement, it has become my lifetime mission to ensure these tubes are placed safely, every time. I invented the RightSpotpH® to address this issue and am thrilled that safe tube placement is now a global focus and that our technology is being recognized as an innovation in that area.”

Safe Placement of NG/OG Tubes

Using evidence-based technology to confirm NG/OG tube placement is important.

Validating correct placement with pH is the standard of care in the UK and is emerging as such in the US.

  • Published research states that up to 56% of blindly placed NG tubes intended for the stomach do not end in the stomach and their mis-placement can contribute to morbidity and mortality (Quandt. J, Pediatr Gastroenterol Nutr. 2009).
  • Pediatric/NICU patients are most vulnerable to misplacement because their stomach and lungs are in close proximity

Currently >70% of US Hospitals use auscultation to confirm placement

  • No clinical evidence supports this method
  • Nursing and Patient Safety Organizations are calling for the immediate discontinuation of auscultation. American Association of Critical Care Nurses (AACN), Children’s Hospital Association (CHA), National Patient Safety Association (NPSA)

Emerging US and Global Clinical Practice based on published studies will be to use pH

RightSpotpH® vs. pH Paper

Why RightSpotpH® vs. pH paper?

Regulatory Guidelines the RightSpotpH® addresses:


  • The RightSpotpH® indicators are the only pH products FDA Cleared and CLIA waived to assist in getting a pH reading of aspirate to help clinicians safely place tubes in the stomach.
  • RightSpotpH® indicators do not expose the clinician to bodily fluids therefore do not require health care workers to use protective wear.
Laboratory Accreditation
  • RightSpotpH® makes it easier for your Point of Care/Laboratory to be compliant
  • The RightSpot pH® is CLIA waived
  • Does not have any regular quality control requirements

Case Study

NICU Nurse Compares RightSpotpH® to pH paper

The attached photo shows a test I performed on a patient with continuous feeds. Patient vomited and pushed his OG tube out so a new tube had to be placed.

Tube was placed and PH was taken using RightSpotpH® indicator on 10 mL BD syringe. PH indicator immediately turned to a gold color closely matching that of 4.5 or less. I pulled several mL’s through indicator and removed indicator to place drops on PH paper. PH paper Lot # 208515 Exp 3/30/18 initially had zero color change. I took the attached photo several minutes later after finishing securing OG and the paper still had little to no change. The residual I pulled from patient stomach was tan/white partially digested formula.

Conclusion from initial use of RightSpotpH® indicator is that it is a much more accurate and reliable way to test PH. Without this indicator I would have had to rely on other means to identify placement of this tube.

I will continue to seek other opportunities to further evaluate this product.
