Heart
Rate
.png)
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 screening purposes, this is considered a realtively 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 Presssure Reading + / - SBP: 10 mmHg + / - DBP: 6 mmHg What does this mean? Helfie Vitals AI screens for 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 screening purposes or for monitoring blood pressure trends over time.

Blood
Oxygen
.png)
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 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
.png)
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.
VAI's Accuracy
ACCURACY Heart Rate Reading +/- 3 Beats per Minute What does this mean? It means that is VAI is wrong in it's reading, at worst your reading is out by no more than 3 beats per minute. Is this Important? Whether or not a difference of +/- 3 beats per minute is statistically important depends on the context and the specific application. In some situations, this level of accuracy may be acceptable or even excellent, while in others it may be insufficient. For example, if you are simply using the Helfie Vitals AI to get a general idea of your heart rate and to monitor it over time, a difference of +/- 3 beats per minute may be perfectly acceptable. However, if you are using the Helfie Vital AI algorithm to make clinical decisions , a difference of +/- 3 beats per minute may not be accurate enough. Helfie's Vitals AI is not for use in a clinical environment and for diagnostic decisions. Additionally, the level of statistical significance of a difference of +/- 3 beats per minute will also depend on the sample size of the data being analyzed. A difference of +/- 3 beats per minute may be statistically significant in a one off or small sample size, but may not be significant in a larger sample size. Helfie AI's continuous readings ensure that your always capturing important data and any small errors over a larger data range are irrelevant. In summary, wether a difference of +/- 3 beats per minute is statistically important depends on the specific application and context of the AI algorithm.
ACCURACY Blood Presssure Reading + / - SBP: 10 mmHg + / - DBP: 6 mmHg What does this mean? Helfie Vitals AI screens for 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 screening purposes or for monitoring blood pressure trends over time. Is it important? Whether a difference of +/- 10 mmHg for systolic blood pressure (SBP) and +/- 6 mmHg for diastolic blood pressure (DBP) is statistically important or not depends on the specific context and intended use of the Helfie AI algorithm. In general, a difference of +/- 10 mmHg for SBP and +/- 6 mmHg for DBP is excellent and acceptable for quick screening purposes, especially if the AI algorithm is being used as a preliminary measure. However, if the AI algorithm is being used for clinical decision making, a higher level of accuracy may be necessary to make accurate diagnoses or treatment decisions. In clinical environments, the level of acceptable error rates may depend on the specific application, the potential consequences of incorrect measurements, and the availability of other diagnostic tools. It is important to consider the intended use and potential consequences of the AI algorithm when evaluating its accuracy and the significance of its error rate. Overall, a difference of +/- 10 mmHg for SBP and +/- 6 mmHg for DBP is acceptable for screening purposes, but may not be sufficient for clinical decision making or for more accurate diagnostic testing.
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. Is it important? A Heart Rate Variability (HRV) error rate of 10ms may or may not be significant, depending on the specific context and intended use of the AI algorithm. HRV is a measure of the variation in time between consecutive heartbeats and is used as an indicator of autonomic nervous system function. A 10ms error in HRV measurement could potentially impact the accuracy of the HRV analysis and subsequent interpretation. In general, a 10ms error in HRV measurement is excellent and acceptable for screening purposes. However, if the HRV analysis is being used for clinical decision making or for research purposes that require high accuracy, a higher level of precision may be necessary. The significance of the 10ms error rate also depends on the sample size of the data being analyzed. In large datasets, a 10ms error rate may be negligible and have minimal impact on the overall results. However, in smaller datasets, a 10ms error rate could potentially impact the accuracy of the analysis and interpretation. Overall, whether a 10ms HRV error rate is significant or not depends on the specific context and intended use of the AI algorithm. It is important to consider the intended use and potential consequences of the AI algorithm when evaluating its accuracy and the significance of its error rate.
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%. Is this important? A 2% error rate in blood oxygen measurement is generally considered acceptable in many clinical and non-clinical settings. In Helfie AI's case as a screening tool, it's generally considered excellent and acceptable. However, whether a 2% error rate is statistically significant or not depends on the specific context and the intended use of the AI algorithm. In your case, if you are using the AI for quick screening purposes only, then a 2% error rate may not be statistically significant, as it is not being used for diagnostic or treatment purposes. In clinical environments, the level of acceptable error rates may depend on the specific application, the potential consequences of incorrect measurements, and the availability of other diagnostic tools. In some cases, a 2% error rate may be acceptable, while in others, it may be considered too high. Overall, a 2% error rate may be acceptable for quick screening purposes, but may not be sufficient for diagnostic or treatment purposes in clinical environments.
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. This is small error rate. Is this important? A 3 rpm error rate in respiratory rate measurement is acceptable for some general screening purposes. However, if the respiratory rate measurement is being used for clinical decision making or for research purposes that require high accuracy, a higher level of precision may be necessary. It is important to note that the reported error rate is based on the algorithm's own testing and validation, and may not necessarily reflect the actual error rate in real-world use. The accuracy of the algorithm's respiratory rate measurement may also depend on various factors, such as the quality of the input data, the performance of the algorithm, and the specific use case. Overall, if an AI algorithm reports an error rate of 3 rpm for respiratory rate measurement, it is important to consider the context and intended use of the respiratory rate measurement, and to verify the accuracy of the measurements through other means if necessary.
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. In this important? Can I rely on the screening? If the Helfie AI algorithm is being used for quick screening in a non-critical setting, such as a personal health app or a wellness program, an accuracy rate of 83% and a specificity rate of 71% is acceptable. However, if the algorithm is being used for more critical purposes, such as medical diagnosis, higher levels of accuracy and specificity may be necessary. It's also important to consider other factors such as the potential consequences of false positives or false negatives and the potential risks of relying solely on AI for stress level measurement. Overall, while an accuracy rate of 83% and a specificity rate of 71% may be sufficient for some quick screening purposes, it's crucial to carefully evaluate the specific context and use case and consider other factors before relying on an AI algorithm for stress level measurement.
AI Accuracy 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.
