Clinical Effect Data related to nastent™

Case of using nastent™ for a patient with SAS

As shown in the graphs, the blood oxygen saturation (top) of OSA patients decreases during sleep, repeatedly falling below 90%. In contrast, the blood oxygen saturation (bottom) of healthy individuals remains constant during sleep. When patients in the top graph use nastent™, the graph flattens, indicating that blood oxygenation has stabilized (middle graph).

Verification of the effect of nastent™ by measuring the blood oxygen saturation with a pulse oximeter

Number of apneas while asleep

The effect of nastent™ Classic for the number of apneas and hypopneas index per hour has been verified for one year.

Example of using nastent™ Classic over a long period → Example of using nastent for a year.

This graph shows changes of AHI (Apnea Hypopnea Index, the number of apneas and hypopneas per hour) of a patient who used nastent classic for approximately one year. The AHI was measured with a simple measurement instrument. Measurement was conducted with and without using nastent classic. In each measurement, using nastent™ classic reduced AHI. It shows that using nastent classic for a long period of time causes AHI to decline and improves breathing while asleep.
