Intended Use

The microMESAM® Basic-Set is used for recording the patient's respiratory nasal pressure during sleep. The device is intended for use as a screening device to determine the need for clinical diagnosis and evaluation by polysomnography based on the patient's test score.

Device Story

Single-channel, battery-powered respiratory pressure sensor system; records nasal pressure during sleep. Patient wears device at home, attached to chest via belt, with nasal cannula for signal collection. After recording, device returned to physician; data downloaded via USB to PC. Software automatically analyzes flow-time curves to detect apneas, hypopneas, flow limitations, and snoring. Physician reviews generated report to determine need for further clinical diagnosis or polysomnography. Benefits include screening for sleep-disordered breathing (SDB) in a home environment, facilitating timely clinical intervention.

Clinical Evidence

Prospective study of 50 patients suspected of obstructive sleep apnea. Compared automated analysis of MicroMESAM flow-time curves against manual scoring of simultaneous PSG data and pneumotachograph curves. Results: 95% correspondence with pneumotachograph; high correlation for apneas (r=0.99), hypopneas (r=0.81), and AHI (r=0.98). Sensitivity/specificity for SDB: 97.3%/46% at AHI=5; 100%/87.5% at AHI=10.

Technological Characteristics

Single-channel, battery-powered (AA/NiMH) recorder. Uses solid-state pressure sensor to convert pressure changes to electrical signals. Includes disposable plastic nasal cannula. Connectivity via USB 1.1 for data download to PC. Complies with IEC 60601-1, IEC 60601-1-2, IEC 60068-2-1, and ISO 10993-1.

Indications for Use

Indicated for adult patients suspected of having sleep-related respiratory disorders to screen for the need for clinical diagnosis and polysomnography.

Regulatory Classification

Identification

A breathing (ventilatory) frequency monitor is a device intended to measure or monitor a patient's respiratory rate. The device may provide an audible or visible alarm when the respiratory rate, averaged over time, is outside operator settable alarm limits. This device does not include the apnea monitor classified in § 868.2377.

The physician prescribed device will help to recognise sleep-related respiratory disorders and lead to comprehensive clinical diagnosis and therapy. The patient may actually perform the recording at home by himself. The microMESAM® recorder must be fastened with the reusable belt on the patient's chest. All relevant respiratory information during sleep will be collected via nasal pressure cannula. The disposable plastic nasal pressure cannula is connected to the microMESAM® recorder and fixed at the patient's nose. After recording, the microMESAM® recorder must be returned to the physician. With the microMESAM® software installed on a personnel computer the physician has the possibility to generate a report with the recorded and analysed data. ### Device Technological Characteristics and Comparison to Predicate Device: The comparison table below, is provided, to demonstrate that the microMESAM® Basic-Set has no siqnificant differences from the predicate device that would adversely affect product safety and effectiveness. | Comparison Parameter | Sector Medical Corp.

Because of costs and labor-intensity it is, however, performed last in graded diagnostic protocols that often involve respiratory pressure measurements via nasal pressure cannula as an alternative sensitive method for DSB detection. MicroMESAM, a newly developed screening device based on this method, allows automated analysis of apnoeas, hypopnoeas, flow limitations and snoring. Aim and Methods: To validate the device, we first compared signal quality of MicroMESAM flow-time curves with those generated by a pneumotachograph. Then, in 50 patients suspected of having obstructive sleep apnoea, we compared MicroMESAMgenerated automated analysis with manually scored results of simultaneously collected PSG data. MicroMESAM-generated flow-time curves corresponded Results: with oneumotachograph-generated curves in 95% of respiratory events, resulting in less 4±2% difference in respective area under the curves. MicroMESAM and PSG generated numbers of apnoeas (r=0.99) and hypopnoea (r=0.81), as well as AHI (r=0.98) correlated highly, displaying mean differences in AHI of 3.8, and in 1.96 intervall of +11.1 to -3.5/h. Sensitivities and specificities for SDB were 97.3%, respective 46% at SDB-defining AHI of 5, and 100%, respective 87.5%, at SDB-defining AHI of 10. {3}------------------------------------------------ Summary: MicroMESAM-qenerated flow-time curves correspond well well with pneumotachograph generated curves, producing automated AHls that are highly sensitive in detecting SDB. MicroMESAM, therefore, is suitable as a screening device for SDB. ## Conclusion: The MicroMESAM® Basic-Set is substantially equivalent to the predicate SECTOR Medical Corp. ApLabTM™. Both Ventilatory Effort Recorders have the same intended use. Based on verification and validation testing completed on the microMESAM® Basic-Set we conclude that the differences do not affect safety and effectiveness of the MicroMESAM® Basic-Set. {4}------------------------------------------------ Image /page/4/Picture/1 description: The image is a circular seal for the Department of Health & Human Services - USA.
