Heart
Rate

In Brief A Heart rate, also known as pulse, is the number of times a person's heart beats per minute. The normal heart rate for adults ranges from 60 to 100 beats per minute (bpm), although this can vary depending on age, physical condition, and other factors. A low heart rate (bradycardia) is generally defined as a heart rate below 60 bpm, while a high heart rate (tachycardia) is defined as a heart rate above 100 bpm. Abnormal heart rates can be caused by various factors, such as exercise, stress, medical conditions, and medications.
Why Check? Heart rate is an important indicator of overall health and fitness, as it can provide information about the heart's ability to pump blood efficiently. A slow heart rate can indicate that the heart is not working efficiently, while a rapid heart rate can indicate an overactive thyroid, stress, or anemia. Regular screening will pick up any variations in your heart health before they become serious issues.
ACCURACY Heart Rate Reading +/- 3 Beats per Minute What does this mean? It means that the Helfie AI Heart Rate algorithm's measurement of a person's heart rate may be up to 3 beats per minute higher or lower than the actual heart rate. This is referred to as the margin of error or the level of precision of the algorithm. It does not mean the algorithm is + or - 3 bmp inaccurate with every measure. On the occasions it may be, this is the range that it is likely to be incorrect. For checking purposes, this is considered a relatively small error rate.
Blood
Pressure

In Brief Blood pressure is the measurement of the force of blood against the walls of the arteries as the heart pumps blood throughout the body. Blood pressure is expressed as two numbers, with the systolic pressure (the top number) representing the pressure in the arteries when the heart beats, and the diastolic pressure (the bottom number) representing the pressure in the arteries between beats.
Why Check? Blood pressure is an important indicator of overall health - providing valuable information about the functioning of the cardiovascular system. Here are some reasons why you should check your blood pressure regularly. Hypertension: High blood pressure, or hypertension, is a major risk factor for heart disease and stroke. Regular monitoring of blood pressure can help you detect and manage hypertension, which can reduce your risk of these conditions. Cardiac health: Blood pressure is directly related to the health of the heart and blood vessels. Changes in blood pressure can indicate changes in cardiac function and may be an early warning sign of heart disease. Medication effectiveness: If you are taking medication to manage blood pressure, monitoring your blood pressure can help you determine whether the medication is working effectively. Kidney function: High blood pressure can also be an indicator of kidney disease, and monitoring blood pressure can help you detect changes in kidney function. Stroke risk: High blood pressure is a major risk factor for stroke. Regular monitoring of blood pressure can help you identify changes that may increase your risk of stroke.
ACCURACY Blood Pressure Reading + / - SBP: 10 mmHg + / - DBP: 6 mmHg What does this mean? Helfie Vitals AI checks blood pressure with a maximum error rate (if any) of + or - SBP: 10 mmHg or = / - DBP: 6 mmHg - this means that the readings produced by the algorithm may be off by up to 10 mmHg for systolic blood pressure (SBP) and up to 6 mmHg for diastolic blood pressure (DBP). For example, if the algorithm produces a reading of 120/80 mmHg, the actual blood pressure may be between 110/74 mmHg and 130/86 mmHg. While a 10 mmHg error rate for SBP and 6 mmHg error rate for DBP may seem high, it is important to note that these error rates are generally considered acceptable for checking purposes or for monitoring blood pressure trends over time.
Blood
Oxygen

In Brief Blood oxygen saturation, also known as oxygen saturation or SpO2, refers to the percentage of hemoglobin in the blood that is saturated with oxygen. Hemoglobin is the protein in red blood cells that carries oxygen from the lungs to the rest of the body.
Why Check? Blood oxygen saturation provides valuable information about the functioning of the respiratory and cardiovascular systems. Regular checks will let you monitor your: Health: Blood oxygen saturation can be used to monitor respiratory health cardiovascular systems. Regular checks will let you stay on top of your: Respiratory Health: Blood oxygen saturation can be used to monitor respiratory health, as low oxygen saturation can indicate problems such as asthma, chronic obstructive pulmonary disease (COPD), and pneumonia. Cardiac Health: Blood oxygen saturation can also be used to monitor cardiac health, as changes in oxygen saturation can indicate changes in cardiac function and may be an early warning sign of heart disease. High-Altitude Illness: At high altitudes, the air pressure and oxygen availability decreases, which can cause low blood oxygen saturation. Checking your blood oxygen saturation regularly when at high altitudes can help you detect and manage high-altitude illness. Sleep Apnea: Low blood oxygen saturation during sleep can be a sign of sleep apnea, a condition in which a person repeatedly stops breathing during sleep. Anesthesia Monitoring: Blood oxygen saturation is also monitored during surgery to ensure that the patient is receiving adequate oxygen and to detect any changes in cardiac or respiratory function.
ACCURACY Blood Oxygen Reading =/- 2% What does this mean? In other words, if Helfie's AI provides a Blood Oxygen reading that is incorrect, the maximum level of inaccuracy would be 2%. This is considered a small error rate.
Respiratory
Rate
.png)
In Brief Respiratory rate is the number of breaths a person takes per minute. The normal respiratory rate for adults is between 12 and 20 breaths per minute, although this can vary depending on age, physical condition, and other factors.
Why Check? A low respiratory rate (bradypnea) is generally defined as a rate below 12 breaths per minute, while a high respiratory rate (tachypnea) is defined as a rate above 20 breaths per minute. Abnormal respiratory rates can be caused by various factors, such as exercise, stress, medical conditions, and medications. Monitoring respiratory rate is important for assessing a person's lung function and overall health. Changes in respiratory rate can indicate potential health issues, such as respiratory infections or metabolic disorders.
ACCURACY Respiratory Rate +/- 3 rpm What does this mean? It means that Helfie AI's respiratory rate measurements may be incorrect by up to 3 breaths per minute. In other words, the algorithm's respiratory rate measurements may be off by as much as 3 breaths per minute from the actual respiratory rate. In th context of screening, this is considered a realtively small error rate.
Heart Rate
Variability

In Brief HRV is the measurement of the time between heartbeats. HRV is considered an important marker of overall cardiovascular health and can provide information about the functioning of the autonomic nervous system. The autonomic nervous system controls many automatic functions in the body, such as heart rate, blood pressure, and digestion.
Why Check? Checking your Heart Rate Variability (HRV) can help you monitor your cardiovascular health, stress levels, recovery, sleep quality, and physical performance. HRV provides insight into the functioning of the autonomic nervous system and cardiac function and can be used to detect changes in well-being and track progress in health and fitness.
ACCURACY Heart Rate Variability =/- 10ms What does this mean? It means that Helfie AI may produce a HRV measurement that is incorrect by up to 10 milliseconds. In other words, the HRV values generated by the algorithm may be off by as much as 10ms from the actual HRV values. A 10ms error rate in HRV measurement is relatively small.
Stress
Level
.png)
In Brief When Helfie AI scans your face to measure stress levels, it is analyzing various facial features to detect physiological responses that are associated with stress. These include changes in skin color, pupil dilation, eye movement, facial muscle tension, and other visual cues that indicate stress.
Why Check? Screening for stress levels through can have several benefits. Firstly, stress is a common problem that can negatively affect a person's mental and physical health. By detecting stress early, individuals can take proactive steps to reduce their stress levels and avoid the negative consequences associated with chronic stress. Secondly, facial scanning for stress levels is a non-invasive and relatively easy method of measuring stress. It does not require any physical contact or invasive procedures, making it a convenient and accessible tool for individuals who want to monitor their stress levels regularly. Lastly, checking for stress levels through facial scanning can also help healthcare professionals and researchers gather more data on stress and its effects. This data can be used to develop better treatments for stress-related conditions and improve our overall understanding of stress and its impact on health.
ACCURACY Stress Level Accuracy: 83% Specificity: 71% What does this mean? An accuracy rate of 83% and a specificity rate of 71% mean that the AI algorithm has a moderate level of performance in measuring stress levels by scanning your face. The accuracy rate of 83% indicates that the AI algorithm correctly identified stress levels 83% of the time. This means that in 17% of cases, the algorithm may have incorrectly identified the stress level. While an 83% accuracy rate may seem high, it is important to note that it still leaves room for potential errors. The specificity rate of 71% means that the AI algorithm correctly identified non-stressful situations (true negatives) 71% of the time. This means that in 29% of cases, the algorithm may have identified a non-stressful situation as stressful (false positives). Overall, an accuracy rate of 83% and a specificity rate of 71% indicate that the AI algorithm has some level of effectiveness in measuring stress levels through facial scanning. Research and testing is ongoing to improvethe accuracy and reduce the potential for false positives for this algorithm.

About VAI
VAI, short for Helfie VItals AI uses advanced health screening technology based on a sophisticated algorithm that extracts RGB components from regions of interest (ROIs) on the forehead, left cheek, and right cheek, using the landmark detection algorithm from the OpenCV library. The raw signal is then processed using the rPPG Core, which consists of the POS algorithm and a filtering stage based on convolutional filters. The POS algorithm, originally proposed by Wang et al., mixes the RGB channels into a single-channel rPPG signal. This algorithm is used to analyze the RGB signal channels and mix them on the time interval t to extract a clean rPPG signal, which provides accurate readings of key health vitals like blood pressure, blood oxygen, heart rate, HRV, respiratory rate, and stress. With VAI, you can monitor your health from your mobile phone and take control of your well-being by tracking your vitals and spotting potential health issues early.
