During the study, participants lie in a supine position in a normobaric hypoxia room while breathing room air with gradually reduced oxygen levels, with the fraction of inspired oxygen (FiO2) decreasing from approximately 21% to as low as 9.5%. The Smart Mask derives SpO2 values from reflected light signals detected by its integrated sensors. Simultaneously, a benchmark pulse oximeter (Nellcor PM10N), worn on the finger, provides reference SpO2 and pulse rate (PR) values for algorithm calibration. Data from reference device are used to refine the conversion of raw photoplethysmography (PPG) signals into SpO2 and PR readings. This phase serves as a feasibility study and is a prerequisite for advancing to subsequent phase. 12 healthy subjects will be enrolled in this study.",[13],"Device: Smart Mask V1 System",{"label":15,"type":10,"description":16,"interventionNames":17},"Invasive (IN)","If the Non-Invasive (NI) phase demonstrates feasibility, the Invasive (IN) study will follow to validate the Smart Mask's measurements against a gold-standard method. This phase involves arterial blood gas analysis to directly measure arterial oxygen saturation (SaO2) using CO-oximetry. Participants undergo the same progressive hypoxia protocol within a controlled hypoxia room. An indwelling radial artery catheter is inserted to allow periodic arterial blood sampling at five predefined oxygen plateaus. The SaO2 values obtained from the CO-oximeter reference device (ABL90 FLEX) are then compared to the SpO2 values calculated by the Smart Mask. 24 healthy volunteers will be enrolled in this phase.",[13],[19],{"type":20,"name":21,"description":22,"armGroupLabels":23,"otherNames":24},"DEVICE","Smart Mask V1 System","PPG-based sensors integrated into a PAP-compatible face mask to measure SpO2 and PR.",[15,9],[25,26],"Smart Mask","SMV1",[28],{"name":29,"affiliation":30,"role":31},"Raf De Jongh, M.D.","Complementair Medisch Centrum (CMC) Europe","PRINCIPAL_INVESTIGATOR",[33],{"name":29,"role":34,"phone":35,"phoneExt":36,"email":37},"CONTACT","+32 477 514 77",null,"raf.dejongh@skynet.be",[39],{"facility":30,"status":40,"city":41,"state":36,"zip":42,"country":43,"countryCode":44,"cosmosGeoPoint":45,"geoPoint":50,"contacts":51},"RECRUITING","Genk","3600","Belgium","BE",{"type":46,"coordinates":47},"Point",[48,49],5.50082,50.965,{"lat":49,"lon":48},[52,53],{"name":29,"role":34,"phone":35,"phoneExt":36,"email":37},{"name":29,"role":31,"phone":36,"phoneExt":36,"email":36},{"type":55,"investigatorFullName":36,"investigatorTitle":36,"investigatorAffiliation":36,"oldNameTitle":36,"oldOrganization":36},"SPONSOR",[57],{"name":58,"class":59},"Haku Technology","UNKNOWN","100599611","validation-of-the-smart-mask-v1-system-and-its-measurements-of-spo2-and-pulse-rate-100599611",false,"NCT07086742","Validation of the Smart Mask V1 System and Its Measurements of SpO2 and Pulse Rate","SMV1: PPG","Inclusion Criteria:\n\n* Healthy subjects with ASA health score of I or II\n* Subjects aged between ≥ 18 and ≤ 65 years.\n* Subjects who have provided informed consent and are willing to comply with the study procedures.\n\nExclusion Criteria:\n\n* Heavy smokers or individuals exposed to high levels of carbon monoxide resulting in elevated carboxyhemoglobin levels.\n* Individuals with conditions that result in elevated methemoglobin levels.\n* Individuals with hypoxia (SpO2 \\\u003C 95% at 21% O2).\n* Severe claustrophobia.\n* Subjects known with altitude sickness.\n* Subjects who are obese (BMI ≥ 35 kg\u002Fm2).\n* Subjects with a known history of moderate to severe heart, lung, kidney or liver disease.\n* Subjects diagnosed with moderate to severe asthma.\n* Subjects with a hemoglobinopathy or history of anemia, e.g. sickle cell anemia, thalassemia, that in the investigator's opinion, would make them unsuitable for study participation.\n* Subjects with any other serious systemic illness.\n* Any injury, deformity, or abnormality at the sensor sites that, in the investigator's opinion, would interfere with the correct functioning of the test or reference devices.\n* Subjects with a history of fainting or vasovagal response.\n* Subjects with a history of sensitivity or allergy to local anesthetics or disinfectants if included in the IN study.\n* Subjects diagnosed with Raynaud's disease.\n* Subjects with unacceptable collateral circulation based on examination by the investigator.\n* Subjects who are pregnant, lactating or trying to become pregnant.\n* Subjects unable or unwilling to provide informed consent or comply with study procedures.\n* Subjects with any other condition that, in the investigator's opinion, would make them unsuitable for the study.\n* Subjects who refuse to remove nail polish from their index finger.\n* Volunteers not willing to remove facial make-up.",true,"ALL","18 Years","65 Years",{"count":72,"type":73},36,"ESTIMATED","INTERVENTIONAL",[76],"NA","The goal of this clinical study is to investigate a new medical device, the Smart Mask V1 System (herein 'Smart Mask'), and particularly its measurements of blood oxygen levels (SpO2) and pulse rate (PR) in healthy adults aged 18 to 65.\n\nMore specifically, the study is directed at answering the following questions:\n\n* Can the Smart Mask accurately measure SpO2 levels compared to established reference devices (reference oximeters, blood gas) throughout the range of SpO2 \\~ 70 -
