The Smart Science within GOQii Smart Vital
With GOQii Smart Vital, you now have convenience on your wrist. The Smart Vital has 4 individual devices bundled in one to measure 4 different Vital parameters.
More so, GOQii Smart Vital is a device that has been recognized by two prestigious institutions in India, namely the Central Drugs and Standard Control Organization (CDSCO, Ministry of Health) and the International Organization for Standardization (ISO). Under CDSCO, the GOQii Smart Vital is approved as a registered medical device (GOQii-MUMBA-MH/M/MD/001104).
It is also ISO certified under the following grades:
- ISO 9001 certification ensures consistency, good quality products and services.
- ISO 13485:2016 certifies an organisation's ability to provide medical devices and related services that meet applicable regulatory requirements.
- ISO 27001 enables organizations to manage the security of assets such as financial information, intellectual property, employee details or information entrusted by third parties.
GOQii Smart Vital uses Photoplethysmography or PPG, which is a method to measure the amount of light that is absorbed or reflected by blood vessels in living tissue. It detects the change of blood volume by the photoelectric technique to record the volume of blood in the sensor coverage area to form a PPG signal.
The 4 integrated LED and Photodiode sensors in the GOQii Smart Vital make this possible. The photodiode sensor detects changes in skin temperature on the wrist and displays your body temperature on the screen. The LED sensors check the speed of blood flow and relative reflection to measure heart rate, blood pressure and SpO2. The combination of green and red light obtain PPG signals, as each light penetrates the human tissue differently. The combination of both the lights can help reflect blood pulse from deep tissue for better accuracy. This technology is convenient and is applied to detect blood oxygen (SpO2 %), heart rate and blood pressure. The added advantage being that it can be measured continuously and at your convenience using this device.
With blood pressure (reported in mm Hg), the normal range for an adult is less than 120 for Systolic & less than 80 for Diastolic (*check the table below).
Your healthcare provider or doctor needs to consider what is normal for you as there are factors such as age, sex, ethnicity, weight, exercise, stress levels, pregnancy as well as medication, disease or a genetic condition which can influence your blood pressure levels.
The diurnal cycle influences blood pressure as well – which is lower in the morning and increases throughout the day until early evening.
The above factors can drastically impact your heart rate as well which can change constantly based on your lifestyle as insufficient nutrition, lack of sleep, insufficient recovery after a workout, illness or medication can affect your heart rate as well.
Do try taking your readings at different times during the day. The App will capture the information and you can monitor your trends.
GOQii Smart Vital, along with the Vital 3.0 have been tested extensively in clinical conditions and is under clinical study by K. J. Somaiya Medical College and Research Center – one of the best private medical colleges which is owned and managed by the Somaiya Medical Trust. The results when compared to medical devices, is as below:
