Intended Use

Intended use for the Flowmate II PLUS is for Pulmonary Function Testing (measuring a person's ability to move air into and out of their lungs). The volume and flow rates measured for the effort and then reported as numerical results with a printout of the results if selected.

Device Story

Flowmate II PLUS is a desktop diagnostic spirometer used in hospitals, clinics, and industrial screening. Device utilizes a flow-sensing pneumotach base to measure differential pressure as air passes through; calculates pulmonary function parameters including FVC, FEV1, FEV1/FVC%, FEF25-75%, PEF, and MVV. System performs automatic test calculations and selects best test results based on ATS 1994 criteria. Clinicians operate device to assess lung function; results are displayed and printed on thermal or standard paper. Cross-contamination is managed via external filter system. Device provides objective data to assist physicians in diagnosing respiratory conditions, monitoring therapeutic efficacy, and evaluating disability or occupational health status.

Clinical Evidence

Bench testing only. Performance validated using a Pulmonary Waveform Generator (PWG) to simulate 24 BTPS waveforms and 26 PEF waveforms. Accuracy and precision for FVC, FEV1, FEF 25-75, PEF, and MVV compared against known 3-liter syringe inputs and ATS 1994 criteria. Results showed device met or exceeded ATS recommendations for accuracy and precision.

Technological Characteristics

Desktop design; molded high-impact UL-rated ABS plastic. Flow-sensing pneumotach; measures differential pressure. Capacity 10L; volume accuracy +/- 3%; max flow rate +/- 16 L/s; back pressure < 1.5 cm H2O. Connectivity: internal/external printer support. Calibration: field-calibrated via 1-9L syringe. Safety: IEC 601-1, UL 2601, EN60601-1-2. Software: automatic calculation and best-test selection based on ATS 1994 criteria.

Indications for Use

Indicated for pulmonary function testing in children and adults. Used for diagnostic evaluation of respiratory symptoms (dyspnea, wheezing, cough, chest pain), signs (cyanosis, diminished breath sounds), or abnormal lab results. Used to measure disease effects, screen high-risk individuals (smokers, occupational exposure), assess preoperative risk, prognosis, and fitness for physical activity. Used for monitoring therapeutic interventions (bronchodilators, steroids), disease progression (obstructive/interstitial lung, cardiac, neuromuscular), and drug toxicity. Used for disability/impairment evaluations (rehabilitation, insurance, legal) and public health/epidemiologic surveys.

Regulatory Classification

Identification

The volume and flow rates measured for the effort and then reported as numerical results with a printout of the results if selected. Waveform performance testing was conducted using a Pulmonary Waveform Generator (PWG), and showed that the Flowmate II PLUS exceeded the ATS recommendations for FVC, FEV1, FEF 25-75 and PEF accuracy and precision at all of the 24, testing under Body Temperature Pressure Saturated with water (BTPS) (see Summary Exhibit 2), and the 26 PEF waveforms (see Summary Exhibit 5). The exhale / inhale performance of the device was tested using exponential waveforms created by the PWG using the same exponential curve in both exhale / inhale maneuvers. FVC, FIVC, PEF and PIF were recorded from four progressively faster exponential waveforms, with the accuracy and precision compared against the known three (3) liter syringe inputs. See Summary Exhibit 3 & 4. MVV testing with the PWG also showed acceptable results compared with the ATS criteria for accuracy and precision to the delivered values (See Exhibit 3 & 4). ## 510(k) SUMMARY {2}------------------------------------------------ EMC and safety testing has shown the device to meet the EN60601-1-2 for emmissions and immunity, and the IEC 601-1 and UL 2601 safety standard for medical equipment. See Summary Exhibit 6. Our conclusion is that the Flowmate II PLUS is substantially equivalent to the predicate device the FlowmateLTE. It is also substantially equivalent to the Flowmate, PC Flow+, Renaissance, and Presto Flash Portable Spirometry System. {3}------------------------------------------------ Image /page/3/Picture/2 description: The image shows the seal for the Department of Health & Human Services USA.
