EtCO2, or exhaled carbon dioxide, is a non-invasive and commonly used measure for respiratory rate and function. It can be easily monitored using a device called a capnograph, which consists of a sensor that is placed near the patient's mouth or nose and a monitor that displays the concentration of carbon dioxide in the respiratory gases in real-time.
EtCO2 capnography is generally considered a reliable and accurate method for monitoring respiration and is often used as a gold standard for comparing the performance of other methods for measuring respiration.
Therefore, the primary aim of this study is to provide a thorough comparison of the performance of Sleepiz One+ and EtCO2 Capnography for measuring respiration rate, in healthy adults and patients suffering from chronic conditions (e.g. hypertension, COPD, asthma, diabetes), at rest in a clinical setting. Additionally, the performance of heart rate estimation will be evaluated against ECG.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Sleepiz One+ vs. gold standard | Other | Each enrolled participant will undergo a simultaneous recording with the Sleepiz One+, Capnography device and cardiorespiratory polygraphy with reduced number of channels (ECG and REB only) to measure respiration rate at and heart rate at rest, while sitting and lying down on a bed. |

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Sleepiz One+ | Device | In this study Sleepiz One+ will measure heart rate and respiration rate of a participant sitting or lying in different positions (right and left side, back, abdomen) on a bed. The recording will take around 35 minutes. |
| Measure | Description | Time Frame |
|---|---|---|
| Respiration rate measurement accuracy per 60s epoch against visually scored capnography data, recorded on subjects lying down and resting on a bed. | 60s |
