(b)(4).Method: the complaint (b)(4) neopuff infant resuscitator was returned to the f&p service center in (b)(4) where it was inspected by a trained f&p service technician.Our investigation is based on the service report and photograph provided by the f&p service technician.Results: the photograph showed that the peak inspiratory pressure (pip) valve's adjustment knob was broken.Conclusion: the neopuff is a portable, reusable device used to assist in the delivery of respiratory breaths to an infant until adequate spontaneous breathing occurs.Being a portable device, the neopuff can be susceptible to damage, for instance when accidentally dropped or subjected to considerable external force.The physical damage observed was most likely due to impact to the subject neopuff unit.It must also be noted that the subject neopuff is 15 years old.The neopuff technical manual states the following: "dropping the neopuff infant resuscitator or other similar forms of impact may cause damage resulting in incorrect operation of the unit.If you suspect damage to have occurred, please perform checks as outlined [in the manual] before connection to a patient".Each neopuff unit is assembled and 100% tested in the production line to verify that each unit conforms to critical product specifications.Any unit that fails is rejected.The subject neopuff unit was repaired and returned to the hospital after passing the performance tests specified on the neopuff technical manual.
