RS01 : Sleep Sensor device

1. What is the RS01 Sleep Sensor Used For?

The RS01 is a sleep apnea screening device that measures blood oxygen saturation (SpO₂) and respiratory airflow.

SpO₂ refers to the estimated percentage of oxygenated hemoglobin in the blood, calculated by comparing the ratio of oxygenated to non-oxygenated hemoglobin. A normal SpO₂ level ranges from 95% to 100%. Levels below 92% are considered insufficient and may indicate respiratory distress.

During the night, the RS01 sensor detects significant variations in oxygen saturation, which are indicative of respiratory events such as apneas and hypopneas.

Respiratory airflow is measured via a nasal cannula placed at the nostrils, detecting the airflow in and out during breathing. This allows the RS01 to identify respiratory pauses (apneas) or reduced airflow (hypopneas).

By combining oxygen desaturation episodes with airflow data, the RS01 provides a comprehensive overview of nighttime respiratory events and helps calculate the Apnea-Hypopnea Index (AHI).

2. What Data Does the RS01 Record?

The RS01 is worn on the wrist like a watch and is connected to a nasal cannula and an oximetry sensor placed on the finger.

The RS01 Sleep Sensor records:

• SpO₂ (blood oxygen saturation)
• Nasal airflow (inhaled and exhaled air)
• Respiratory rate (breathing frequency)

You can choose between two recording modes:

• Manual mode: You start and stop the recording yourself.
• Scheduled mode: You program your sleep hours in advance so the device activates automatically when you sleep.

The device can record continuously for up to 20 hours. In cases of low battery, disconnected sensor, or exceeded storage time, an adjustable alarm may be triggered.

3. How to Retrieve the Data?

All recordings can be accessed via a dedicated analysis software (provided free of charge). The device features a USB port, allowing connection to a computer with a cable.

The software, called ResMon, enables data import after each recorded night. Users can enter their personal information (name, age, height, weight) to store and organize their sleep data.

Once the data is imported, you'll be able to view detailed graphs of:

• Nasal airflow (Flow)
• Oxygen saturation (SpO₂)
• Heart rate (Pulse)

The software also allows you to generate a comprehensive report summarizing:

• Your oxygen saturation levels
• Your Apnea-Hypopnea Index (AHI) per hour of sleep

The report can be downloaded as a PDF file and shared with a physician for further medical interpretation.

Conclusion

The RS01 is a high-quality, reliable sleep apnea screening device, suitable for both healthcare professionals and private individuals. While the device is user-friendly, we recommend consulting a medical professional to interpret the results accurately.

It is particularly useful:

• If you suspect symptoms of obstructive sleep apnea
• For monitoring AHI before, during, or after treatment (such as CPAP or mandibular advancement devices)
