M-PRO, LLC designed the NPak nasopharyngeal aspiration kits to the highest quality and safety standards. To achieve the best results, we recommend following the instructions provided on this page and in our online brochure.
Patient should lie on their back with neck extended. Neck extension is important as this allows pooling of the aspirate in the nasopharynx.
The catheter is lubricated generously with the supplied lubricant (optional).
An appropriate volume of saline is retained or expelled in the syringe according to age.
Patient is instructed to hold their breath for a few seconds, and the catheter is advanced to the appropriate age depth marking or until resistance is met abutting the nasopharynx.
The syringe plunger is quickly pushed and pulled. The aspirate sample is adequate if between 0.5-1 cc is collected of the volume instilled.
The catheter tip is then detached and the Luer-Lock cap is tightly secured. The aspirate specimen can then be transported to the lab in the capped syringe.
