Scoop on some of the Helo technology

Got a Technical question from someone about "how does the Helo work?"

Here's the scoop on some of the Helo technology:

Photoplethysmography (PPG)

By Susha Cheriyedath, MSc

Photoplethysmography (PPG) is a simple optical technique used to detect volumetric changes in blood in peripheral circulation. It is a low cost and non-invasive method that makes measurements at the surface of the skin.
The technique provides valuable information related to our cardiovascular system. Recent advances in technology has revived interest in this technique, which is widely used in clinical physiological measurement and monitoring.

Principle of PPG

PPG makes uses of low-intensity infrared (IR) light. When light travels through biological tissues it is absorbed by bones, skin pigments and both venous and arterial blood.

Since light is more strongly absorbed by blood than the surrounding tissues, the changes in blood flow can be detected by PPG sensors as changes in the intensity of light.

The voltage signal from PPG is proportional to the quantity of blood flowing through the blood vessels. Even small changes in blood volume can be detected using this method, though it cannot be used to quantify the amount of blood.
A PPG signal has several components including volumetric changes in arterial blood which is associated with cardiac activity, variations in venous blood volume which modulates the PPG signal, a DC component showing the tissues’ optical property and subtle energy changes in the body.

Some major factors affecting the recordings from the PPG are site of measurement and the contact force between the site and the sensor.

Blood flow variations mostly occur in the arteries and not in the veins.

The PPG Waveform

PPG shows the blood flow changes as a waveform with the help of a bar or a graph. The waveform has an alternating current (AC) component and a direct current (DC) component.

The AC component corresponds to variations in blood volume in syncronization with the heart beat. The DC component arises from the optical signals reflected or transmitted by the tissues and is determined by the tissue structure as well as venous and arterial blood volumes.

The DC component shows minor changes with respiration. The basic frequency of the AC component varies with the heart rate and is superimposed on the DC baseline.

Uses of PPG

Medical devices based on PPG technology are widely used in various applications in the clinical set up.
Specific applications include the following:

Clinical physiological monitoring
Blood oxygen saturation
Blood pressure
Cardiac output
Heart rate
Respiration
Vascular assessment
Arterial disease
Arterial compliance and ageing
Venous assessment
Endothelial function
Microvascular blood flow
Vasospastic conditions
Autonomic function monitoring
Vasomotor function and thermoregulation  

Blood pressure and heart rate variability
Orthostasis
Other cardiovascular variability assessments

Wearable Devices

Using this technology, wearable pulse rate monitors have been developed. These low-cost and small devices have high-intensity green light-emitting diodes (LEDs) and photodetectors that help reliable monitoring of the pulse rate in a non-invasive manner.
Important design requirements for these systems include miniaturization, robustness and user-friendliness.

These devices have a sensor that monitors minor variations in the intensity of light transmitted through or reflected from the tissue. These intensity changes are associated with changes in blood flow through the tissue and provide vital cardiovascular information such as the pulse rate.

Other Systems

PPG has been used in other technologies such as telemedicine, PPG imaging technology and remote monitoring.

Researchers have studied skin blood flow and the related rhythms using a near infrared CCD PPG imaging system. This study aimed at obtaining fresh insights into biological tissue perfusion and studying changes associated with wound healing and formation of ulcers.

Other studies have applied PPG in remote imaging of the distribution of arterial oxygen saturation (SpO2) within a tissue. Such an image might be valuable in medical diagnostics studies such as quantification of tissue viability. In telemedicine, PPG is promising in remote monitoring of patients’ health.

Launch Of World's First Wearable, Non-Invasive, Continuous, Blood Glucose Estimation Technology Using WRMT's Smart Wristband, Helo, Will Generate Recurring Revenues For WRMT

MIAMI, Jan. 10, 2017 /PRNewswire/ -- World Media & Technology Corp. ("Wor(l)d") (www.worldmediatech.com) (OTC PINK: WRMT), today announced that its research activity generating non-invasive, continuous blood glucose estimates has been found to be sufficiently accurate to allow WRMT to proceed to full integration of the algorithm in the Helo platform so WRMT can offer blood glucose estimation as a service in Q4'17 to Helo wearers who choose to pay an initial set-up fee and an ongoing monthly charge.

According to the International Diabetes Federation, 415 million people worldwide (1 in 11 people) have diabetes consuming 12% of global health expenditure ($673B) in 2015. The American Diabetes Association advises that in the US, nearly 30 million (1 in 8) people have diabetes and $1 in $5 health care dollars is spent caring for people with diabetes.  Americans with diagnosed diabetes incur average medical expenditures of about $13,700 per year, of which about $7,900 is attributed to diabetes.

The importance of blood glucose (blood sugar) monitoring is the main tool used to check diabetes control. The current mainstream blood glucose measurement process is to use a lancing device on the side of the fingertip to get a drop of blood, touch the test strip to the drop of blood, and wait for the result. Apart from being painful for the diabetic, there are health risks due to the invasive nature of the process as well as measurement compliance and recording issues. 

Helo's features today include measurement of Blood Pressure, ECG, Heart Rate, Respiration Rate, Heart Rate Variability (HRV) analysis for mood and energy levels along with measuring steps, distance and calorie burn.  However, this is the first time anyone has used a photoplethysmograph (PPG) to estimate blood glucose levels and incorporate the technology into a wearable device to provide convenient, non-invasive blood glucose estimation and logging on a continuous basis.

Helo is not a medical device, but continuous measurement of blood glucose estimates are expected to be helpful in understanding blood glucose changes over time, aid compliance and support a pre-diabetic seeking to change their lifestyle to avoid diabetes.

WRMT's blood glucose estimation service is non-invasive, and can be scheduled to record blood glucose estimates routinely with readings stored in Helo's LifeLog for easy presentation to the diabetic's health care provider. In the event that Helo detects a blood glucose problem, Helo's Guardian service will automatically alert the wearer and their care giver. It is expected that this service will initially be available in Q4'17, to all Helo wearers who opt-in for the service and who pay the initial fee to cover registration and to start blood glucose monitoring.

Fabio Galdi, CEO, World Media & Technology Corp., said, "I am personally excited by this development. It is the first time that I am aware that PPG technology has been used to estimate blood glucose in a wearable device designed for the consumer wellness market.  It will address a very real, painful and expensive need. Our test results have proven consistent with traditional blood glucose measurements so we have decided to start integration to provide this as a full Helo service later this year." He continued, "By the time that we launch, we will have enough Helo wearers all over the world to generate a very valuable blood glucose data base.  Our plan is to share this data via our Big Data Portal with appropriate research partners.  We are sure that together we can gain valuable insights and who knows, maybe somewhere, buried below all that data our research partners may find the cure for diabetes!"

Helo Team,

Happy New Year!  

Are you glad 2016 is behind you or was it a good year?

Most are saying bring on 2017 and hoping for better.

Success TIP:  Relationship Equity should be your #1 Goal.  Build up others and watch magic happen.  Don't have an agenda. 

Well, 2017 has already begun with a plug.  A free plug on FOX about Helo.  A free gift in my opinion.  

If you know anyone in LA invite them out January 7th to take a free look at the hottest opportunity in the tech space.  If a skeptic send them to stock ticker WRMT.

I've paid 100s to hear Chanida and Nattida speak in Dallas at anmp.com.  Our leadership in Worldgn is the best on the planet.  

Helo will save lives in 2017.  Let's spread the word with Wor(l)d.
