H10: manufacturing review: a manufacturing review was not required as this is the only complaint reported to date for this product and lot.Investigation summary: one presto inflation devices has returned for evaluation, on the visual evaluation of the device it appeared to contain some saline residue and liquid in the chamber and the piston had fully retracted.On the functional evaluation of the device, the button toggled easily and liquid in the chamber has cleared out.Then by using the returned valve the liquid has filled and it has noted the pressure raised on the inflation device and the gauge needle would go up.On upon depressurize the chamber the gauge needle moved slowly to 0 atm and found stuck.Then the inflation device has connected to pressure gauge and the piston get twisted to reach 8 atm and the pressure on the pressure gauge has noted at 8 atm.Then the button in the presto device toggled and the needle returned to 0 atm slowly and stuck at 4 atm.Therefore, the reported pressure gauge failed to work was confirmed as the needle of presto devices got stuck and moves slowly while depressurizing the device back to 0 atm.A definitive root cause for the alleged pressure gauge failed to work could not be determined based upon the provided information.Labeling review: the review of the instructions for use, indications, warnings, precautions, cautions, possible complications, and contraindications showed that the product labeling is adequate.H10: b5, d4 (expiry date: 03/2023), g3.H11: d4 (medical device lot), h6 (method, result, conclusion).H11: section a through f ¿ the information provide by bd represents all the known information at this time.Despite good faith efforts to obtain additional information, the complainant/reporter was unable or unwilling to provide any further patient, product, or procedural details to bd.
