{0}------------------------------------------------ ## APR 3 0 1998 K980411 #### Section 16. 510(k) Summary #### Section 16.a Date Summary Prepared 30 January 1998 #### Section 16.b Company Information Establishment: Official Correspondent: Nellcor Puritan Bennett Inc. 4280 Hacienda Drive Pleasanton, CA 94588 David A.C. Green Manager, Regulatory Affairs Nellcor Puritan Bennett Inc. 11150 Thompson Avenue Lenexa, KS 66219 (913) 495-7140 (direct phone) (913) 495-7285 (fax) #### Section 16.c Name of Device Proprietary: Common/Usual: Classification: NPB-500 Spirometry System Spirometer Spirometer (§868.1840/73BZG) # Section 16.d Equivalent Devices Substantial equivalence to the following legally marketed predicate devices with the same or similar indications for use has been demonstrated by a comparison of product features as described in the labeling and promotional literature for the predicate devices and the NPB-500 Spirometry System. Safety and environmental testing to accepted industry standards has been conducted as well as in-vitro testing to confirm the accuracy of the NPB-500 Spirometry System. The predicate devices are as follows: - 1. Nellcor Puritan Bennett Inc., NPB-Renaissance Spirometer, K944762 - 2. Vitalograph Ltd., Model 2120 Spirometer, K946075 #### Section 16.e Device Description The NPB-500 Spirometry System comprises the following five components, including accessories: NPB-500 Spirometer (hand held), Flow Sensor II, Pressure Tubing, NPB-510 Spirometer Base (optional) and Printer/PC Cable (optional). Two versions of the cable are available, namely, a parallel cable for a Printer and a serial cable for a PC. {1}------------------------------------------------ The NPB-500 is a hand held diagnostic Spirometer intended for patient use in the performance of Forced Vital Capacity, FVC, testing. The patient performing a test is requested to take a deep breath and then exhale vigorously and continuously into the sensor's mouthpiece until complete exhalation is achieved. Initially, the testing process requires patient cooperation and supervisory coaching to achieve optimum results. FVC parameter test results may be displayed on the Spirometer's front face LCD display. Alternatively, the Spirometer can be inserted into the optional Spirometer Base, enabling data to be interfaced, via an output data port, to a parallel printer for graphical printout of the patient's test record, or to a PC. In addition to the above mentioned device features, the instrument has been designed to satisfy the needs of both the user and the patient. An audible, mid frequency, beep tone is provided to prompt the User for input, inform the User of the successful completion of a process step or warn of low battery condition. The NPB-500 System is powered by two AA size standard alkaline batteries which can provide an estimated operating time of six months under normal use. #### Section 16.f Intended Use The NPB-500 Spirometry System is intended for prescription use only to conduct simple diagnostic forced vital capacity (FVC) testing of adults plus pediatric patients, in the patient examination rooms of a physician's practice and in hospital or hospital-type facilities such as respiratory care centers. The intended use, patient population and environment of use are the same or similar to the predicate devices, the NPB-Renaissance Spirometer and the Vitalograph model 2120 Spirometer. ### Section 16.g Technological Characteristics A pneumotachometer sensor is used to convert the expired breath flow signal into a pressure signal. The NPB-500 Spirometry System measures the values of FVC parameters by continuously sensing this pressure throughout an expired breath. This signal is pneumatically coupled to a pressure transducer in the NPB-500 Spirometer to develop corresponding electrical data. Conventional electronics and embedded software are used to process this data and generate numerical values of FVC parameters for presentation on the NPB-500's LCD display. Alternatively, graphical test results may be recorded on a printer. The embedded software contains substantially the same software algorithm for determining test values of FVC parameters as used on the predicate device, the NPB-Renaissance, cleared under K944762, except for the inclusion of non-linear correction terms in the pressure/flow equation of the sensor. {2}------------------------------------------------ ## Section 16.h Certification Statement In accordance with the requirements of 21 CFR 807.87(j), the following certification is provided: Nellcor Puritan Bennett Inc. believes that all data and information submitted in this Premarket Notification are truthful and accurate and no material fact has been omitted.

Food and Drug Administration 9200 Corporate Boulevard Rockville MD 20850 APR 3 0 1998 Mr. David A.C. Green Nellcor Puritan Bennett Inc. 11150 Thompson Avenue Lenexa, KS 66219-2301 K980441 Re: NPB-500 Spirometry System Regulatory Class: II (two) Product Code: 73 BZG Dated: February 3, 1998 Received: February 4, 1998 Dear Mr. Green: We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major requlations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such Failure to comply with the GMP regulation may result in assumptions. regulatory action.
