￼iHeart lets you measure and track your internal age. There is an abundance of research that indicates a strong relationship between arterial stiffness, heart health and the risk of premature death from all causes. Until now, you needed equipment costing thousands of dollars to accurately measure your aortic stiffness. iHeart is an inexpensive solution that clips on your finger and provides results in 30 seconds.
Imagine a single health metric able to identify people in their 20’s at increased risk for development of Heart Disease, Stroke and Dementia. What if this health indicator could estimate how long you will live? Incredibly, for the last 20 years medical scientists have known that Aortic Pulse Wave Velocity, which is used to measure stiffness of the Aorta (shown below) is closely related to risk of death from all causes and able to define risk in young people for development of Heart Disease Stroke and Dementia.
You and your doctor probably haven’t heard of Aortic Pulse Wave Velocity because this measurement has required expensive and complicated equipment with a price tag of over $20,000 USD
Aortic Pulse Wave Velocity is closely related to and is a measure of stiffness along the spinal column. Increased stiffness of the spine results in decreased mobility of the body’s core regions affecting chest wall and diaphragmatic motion. When pulse wave velocity increases in speed, Core Mobility is reduced and the Internal Organs receive less of a massaging action with each breath. This decreases organ circulation, affecting organ function, overall health and longevity.
Aortic Pulse Wave Velocity not only assesses risk of illness but also shows improvement with attention to diet, exercise and stress management. Aortic Pulse Wave Velocity is a way to ‘look inside’ and can help people objectively appreciate the benefit of positive lifestyle choices.
How is Pulse Wave Velocity measured?
Measurement in the past used pressure sensors placed precisely over the Carotid artery in the neck and the Femoral artery in the groin to measure speed with which pulse waves travel down the Aorta. Aortic Pulse Wave Velocity (AoPWV) is the common way scientists measure of Aortic Stiffness.
Recently it has become possible to measure AoPWV using a single fingertip pulse sensor and application called iHeart Internal Age. iHeart uses a 30-second test to locate and characterize a wave in the fingertip pulse signal that travels down the Aorta, reflects back from the distal Aorta towards the heart and then travels on to the finger. The speed with which this Reflected Wave travels is closely related to Aortic Stiffness. iHeart Aortic Pulse Wave Velocity measurement has been tested against the ‘gold standard’ Carotid-Femoral AoPWV measurement system and found to correlate very well. Below you can see the reflected wave in the pulse shape of both a young person, and old person.

Above you can see the wave pattern while the iHeart test is being performed.
There are other ways to measure AoPWV. One alternative method uses a pulse sensor on a finger and a toe. The distance from the heart to a fingertip and the distance from the end of the Aorta and down a leg to a toe is about the same. The difference in arrival time of the finger and toe pulses is closely related to AoPWV but age creates errors when compared to Carotid-Femoral PWV.

It is important to recognize that not all PWV measurements are good indicators of health and predictive for risk of illness. Aortic Pulse Wave Velocity is the only metric able to assess overall health and predict lifespan.
What can be done to improve Aortic Pulse Wave Velocity and Internal Age?
Many factors can increase pulse wave velocity and Internal Age. Things like:
Your first iHeart Internal Age/AoPWV reading is a starting point, using the iHeart device you can see how your lifestyle choices are affecting pulse wave velocity and Internal Age, and tweak your life- style to achieve the lowest Internal Age possible, improving health and increasing lifespan.
Lifestyle factors that may lower a user’s pulse wave velocity and Internal Age:
• Increased movement/activity*
• Improved diet
• Improved sleep quality
• Improved stress levels
• Dietary supplementation**
• Increased hydration levels
How do I test correctly with my iHeart device to accurately measure Pulse Wave Velocity?
To achieve an accurate test follow these steps:
• Try to test at the same time each day
• Sit for 2 minutes before testing
• Do not talk or move while testing
• Do not test within two hours of drinking coffee, alcohol, or smoking a cigarette
Think of the pulse wave velocity test like a blood pressure cuff at the drug store, you wouldn’t be moving, you would have sat there for a couple minutes while the machine prepared to test your blood pressure. iHeart pulse wave velocity testing protocol is quite similar.
How long until I see my pulse wave velocity score change?
The great thing about iHeart and the pulse wave velocity and Internal Age test is that changes are seen quite quickly after a user begins incorporating positive choices into their lifestyle. We suggest testing at the same time each day to attain your baseline, but you can also test before and after specific activities to see how those activities or habits affect you on the inside. Use iHeart to learn how your body reacts to different stimulus and keep up with the good, and ditch the bad. Soon you’ll see your pulse wave velocity score and Internal Age drop, improving health and increasing lifespan.
What is a good pulse wave velocity score?
Below is a graph that shows optimal pulse wave velocity scores for different ages, with iHeart. Pulse wave velocity is measured in meters per second (m/s).

We've asked the COPD community if there are key times to measure your blood oxygen levels, and according to the responses, there are! To put a spin on it, we made a handy infographic displaying the best times to use your pulse oximeter to measure oxygen saturation. This is especially handy for people who have just been prescribed to oxygen therapy. Take a look!
Back in the 1940s, when oximetry was first being used by wartime pilots in the U.S. military, "aviation ear meters" could indicate the blood/oxygen status of pilots flying at high altitudes. This technology was modified and improved during the '50s and later marketed for use in hospitals in the late 1960s. Unfortunately, these new devices were heavy and cumbersome and had bulky, uncomfortable earpieces. They were also very expensive, selling for somewhere around $10,000.
Today's pulse oximeters, by contrast, are small, easy-to-use devices that can be purchased for less than $20, carried in your pocket and simply slipped over your fingertip any time you want to check the oxygen saturation level of your blood. The technology has continued to improve over the past decades. Today, Pulse-Ox units are primarily utilized in home healthcare environments, in emergency response vehicles and in hospitals and clinics. There is, however, an ever-growing market of users who want the benefits oximeters can offer to tourists visiting areas located in higher altitudes, climbers and athletes competing at high elevations.
What We Learned from Mexico City
Most would agree that the air is "thinner" at higher altitudes and that less oxygen is available for breathing. The fact is, air always consists of the same 20.93% oxygen (O2), regardless of elevation. What does decrease as elevation increases is air pressure. And, as atmospheric pressure lessens so does the amount of oxygen you breathe in with each breath. This, in turn, causes respirations to increase as compensation. There will also be a corresponding drop in the percentage of oxygen saturation in your bloodstream.
Normal blood oxygen readings at sea level are between 95-98%. When you breathe in, the oxygen going into your lungs exerts something called "partial pressure" which corresponds directly to ambient atmospheric pressure. This is important because the partial pressure in your lungs is greater than the pressure in the blood (hemoglobin) surrounding your lungs. At sea level, the partial pressure of O2 is 159mmHg. In Mexico City however, at an altitude of more than 7,200', oxygen's partial pressure is only 125mmHg. It was discovered during the 1968 Olympics in Mexico City that higher elevations meant lower blood oxygen saturation, leading to decreased athletic performance. Breathing supplemental oxygen could bring temporary relief from these low oxygen levels and is now commonly used during competitions at high altitude as well as other activities taking place at higher elevations.
Deadly Airplane Crashes Cause Hypoxia Concerns
In September, 2014, two small airplanes went down and suspicions pointed to pilot unconsciousness due to hypoxia, or inadequate oxygenation of the blood. Symptoms of hypoxia include:
Sweating, lip tingling
Raised heart rate
Although symptoms will vary from one individual to another, you might think that avid, experienced pilots, as these two were, would be aware of the problem and do something to remedy it. If, however, confusion is a factor, thoughts may become illogical.
After these incidents occurred, the AOPA (Aircraft Owners and Pilots Association) sent out a message of concern to their members warning of the dangers hypoxia posed to pilots, especially those operating aircraft with non-pressurized cabins. They went on to state that, in their opinion, use of a pulse oximeter "is the best defense against hypoxia," and they recommended the use of these devices to check for blood saturation levels every ten to fifteen minutes while flying.
While FAA regulations require the use of supplemental oxygen for pilots operating at certain altitudes (FAR Part 91, Sec 91.211), none have yet to require use of pulse oximetry for checking blood oxygen levels quickly and dependably.
Normal Home Altitude Saturation Levels
If you're thinking of going on a northern nomadic expedition or, perhaps, climbing Kilimanjaro, you'd be smart to have a pulse oximeter in your pocket. How you respond to being at significant altitudes will depend partly on the elevation where you normally live. Most people living at sea level will have blood oxygen saturation levels of 95%+, which is normal. If, however, those same people were atop Mt Kilimanjaro, which stands at nearly 20,000', a "normal" saturation level is between 70-75%.
In addition, saturation level and saturation tolerance are two different things, and each person will tolerate a reduced oxygen level differently. Although much will have to do with the elevation level at which you normally live, reactions to high altitude also depend on other factors such as:
Tobacco smoking history
Exercise history, and more
Tourists/vacationers planning to spend time at any high altitudes should definitely take the precaution of having a pulse oximeter in their pockets and ready access to supplemental oxygen. The same goes for climbers, competing athletes and pilots.

Sleep apnea often goes unrecognized and untreated, yet it affects as many as 18 million Americans alone. Sleep apnea is a condition that affects your breathing during sleep in one of three of ways:
Obstructive Sleep Apnea – The most common type, obstructive sleep apnea occurs when the soft tissue in the back of your throat relaxes and blocks the airway, disrupting breathing and causing snoring.
Central Sleep Apnea – Much less common, central sleep apnea occurs when the brain fails to send signals to the muscles that control breathing, disrupting normal breathing and sometimes causing snoring.
Complex Sleep Apnea – The least common, complex sleep apnea is a combination of both obstructive and central sleep apnea.
All forms of sleep apnea disrupt normal sleep cycles as breathing is interrupted throughout the night, typically for 10 to 20 seconds, up to hundreds of times per night. Left untreated, sleep apnea can lead to: diabetes, heart disease or heart failure, stroke, weight gain and high blood pressure. While identifying sleep apnea on your own can be difficult – most people don’t remember waking up during the night – there are some signs you can keep an eye out for.
Signs of Sleep Apnea
If your partner frequently complains about loud snoring followed by gasping or choking noises, there’s a good chance you have sleep apnea. If you don’t sleep with a partner, you can record yourself during the night to find out if you are snoring and gasping. Additional signs include: morning headaches, sleepiness throughout the day, learning problems, mood swings or personality changes, or having a dry mouth and sore throat when you wake up.
Sleep Apnea Causes
Sleep apnea is more prevalent in men, smokers, overweight people and those over the age of 65. Additional risk factors include having a deviated septum, a thick neck or enlarged tonsils (a common cause of sleep apnea in children). With treatment however, those who suffer from sleep apnea can control the symptoms and get their sleep and life back on track.
Sleep Apnea Treatments
There are many at-home remedies you can try, including quitting smoking, avoiding alcohol and sleeping pills, and maintaining regular sleep hours. You can also try sleeping on your side, propping up your head and opening your nasal passages with breathing strips or a nasal dilator. Recent studies show regular exercise and respiratory trainers can also help those who suffer from severe sleep apnea.
If you cannot find relief on your own, it’s time to see a doctor. Your doctor can help determine if you have sleep apnea, the cause, and most importantly, the best treatment option for you.

Before the 1960s, any form of cardiac arrest almost assured death. In an attempt to save more lives, surgeon and medical innovator Peter Safar developed a combination of mouth-to-mouth breathing and chest compressions that would open up airways and maintain adequate oxygen levels in non-breathing victims that could resuscitate them. His system for cardiopulmonary resuscitation was adopted by the American Heart Association in the 1970s and has since been standardized as the process for CPR.
Medical emergencies can occur at any time, and often without any warning, so getting CPR certified is a fairly simple and useful process that will equip you with the skills to respond quickly and properly when someone needs assistance.
A CPR certification typically lasts for two years and is easy to obtain by attending a class at a certified training center. If you’re not planning on working as a lifeguard, teacher, babysitter or something in a related field, it is still smart to get certified even if your workplace doesn’t require it. You never know when you could be faced with the opportunity to save a person’s life.
Do some research – The first step in getting your certification is to do some online research about the kind of class you will need to take. CPR classes are typically offered as either healthcare specific or for the general public and are designed to meet different needs based on whether the certification is required by your workplace or if you want to prepare yourself for an emergency situation.
Search for classes – You can call your local gym or municipal swimming pool to see if they offer CPR certification classes, but you can also search online to find other training centers close to you. The Red Cross and the American Heart Association both have a useful search tool that allows you to search by zip code. Some centers will offer both classroom and online class options, but be wary of online classes that don’t require you to come in for a skills evaluation at the end of the course to receive your certification card - this is usually a scam and most workplaces won’t accept a print-out certification card.
Register for classes at your convenience – Classes are usually offered year-round, so you can obtain your CPR certification whenever you have the time to do so. If you are under some time constraints to receive your certification, find out how long it will take to receive your card so you can plan accordingly. Some training centers will present you with it after your final in-person skill evaluation, while others may be mailed to you after completing the course.
Attend classes and get certified – Congratulations! You’ve completed your course work, gotten your CPR certification and are now ready to act accordingly in the event of a medical emergency!
When acting quickly to resuscitate a victim can often mean the difference between life and death, getting CPR certified is a small price to pay when you know that you can save someone’s life. Visit American Heart Association and Red Cross for more information about CPR training and where you can find a training center near you.
