San Francisco-based startup iBeat launched its pulse-sensing iBeat Heart Watch, which aims to alert medical professionals if someone is going into cardiac arrest.

Inspired by the death of a friend who could have been saved by CPR, Ryan Howard, founder and CEO of iBeat, said he decided to start working on a device that could prevent deaths. The team came up with a watch that could check 12 physiological markers and then connect to services.

One of the main goals is to get help to people who are going through cardiac arrest and can’t call for help themselves.

“Let’s say you were wearing that device and you stop breathing. So, for example if you were having a cardiac arrest you would have ‘pulseless-ness,’” Howard told MobiHealthNews. “We would engage you and ask ‘are you ok, yes or no?’ If you are truly having a cardiac arrest or you are truly not breathing, you are going to be incapacitated fully. This is not like a heart attack or a stroke, you would be out cold.”

After the device has checked in, it can start to take action and connect to emergency medical services.

“So the watch is going to count down for ten seconds and if you don't answer, what the device is going to do is it has a full LGB cell radio and GPS so it doesn’t need to be attached to a phone," he said. "It is going to be fully autonomous. It is going to reach out to our cloud platform our 24-7 multilingual dispatch that is going to coordinate with 911. We have a direct connection to the 911 system, and what we are doing is giving them data about you. Your location, when you set the device up originally we gathered your medical conditions allergies, medications, and all of that data, so we gave it to paramedics while they are en route to your location.”

The system is intended for people with a history of cardiac problems. Users are also able to connect family members and caregivers to the alert system.

When a person goes into cardiac arrest for too long it can cause long-lasting brain damage or death. To combat this, iBeat is going to be looking to the help of vetted individuals willing to pitch in.

“You have about three to five minutest to get CPR because what is going to happen is the lack of oxygenated blood to your circulatory system is going to cause chronic impairment very quickly,” Howard said. “The challenge with that is that the EMTs on average are nine to 12 minutes away and emergency contacts are even further away. What we have done is created a proprietary network of CPR-trained good Samaritans called Heart Heroes. They are available via an app … what it does is it can train you in CPR and tests you, and the test is very vigorous.  Then when you go through that, the app will ask are you open to being a good Samaritan.”

If someone is going into cardiac arrest nearby, a Samaritan will be contacted. In addition to the pulseless-ness detection, there is a button on the watch that can connect a user to help if they have another emergency.

Right now the company has a waitlist for 50,000 people and it is looking to link up with life insurers who, Howard said, are interested in the longevity of a client. 

In May the startup landed $5.5 million in funding and said the goal was to use the funding to launch the Heart Watch.

Fluoxetine oral capsule is available as the brand-name drugs Prozac and Prozac Weekly. It's also available as a generic drug. Generic drugs usually cost less than brand-name versions. In some cases, they may not be available in every strength or form as brand-name drugs.

Fluoxetine oral capsule may be used as part of a combination therapy. This means you may need to take it with other medications. For the treatment of depressive episodes related to bipolar I disorder and treatment-resistant depression, this drug must be used with olanzapine.

Fluoxetine oral capsule belongs to a class of drugs called selective serotonin reuptake inhibitors (SSRIs). A class of drugs is a group of medications that work in a similar way. These drugs are often used to treat similar conditions.

Fluoxetine works by increasing the amount of serotonin (a natural substance) in your brain. Serotonin helps maintain mental health balance. An increase in serotonin helps to treat symptoms of depression, obsessive-compulsive disorder, bulimia nervosa, and panic attacks.

A blood gas test is also called an arterial blood gas test or a blood gas analysis. It measures oxygen and carbon dioxide levels in the blood. The test can also show blood pH levels and lung function.

Doctors often use blood gas tests in emergency situations to help diagnose the cause of breathing difficulty.

Purpose
A blood gas test can help to diagnose lung problems.

Anyone who is struggling to breathe or who has a lung-related health issue will undergo a blood gas test. The results can help a doctor to identify the cause of symptoms.

A blood gas test can show how well the lungs, heart, and kidneys are working.

More specifically, results of the test can help a doctor to:
•diagnose lung and breathing problems
•check whether treatments for lung conditions are working
•determine whether a person has a ruptured blood vessel, metabolic disease, or chemical poisoning

Doctors also use the test to check the acid-base balances in people who:
•have kidney problems
•have diabetes
•are recovering from drug overdoses

Takeaway
A doctor usually performs a blood gas test in a hospital, when a person has a severe illness or injury.

The doctor will draw blood from an artery in the wrist to check how well the lungs and kidneys are functioning.

Results of a blood gas test can help to determine the cause of breathing problems. However, a doctor will also consider results of other tests before making a diagnosis.
