Sudden cardiac arrest is a leading cause of death in adults. Cardiac arrest is an electrical malfunction in the heart that causes an irregular heartbeat (arrhythmia) and disrupts the flow of blood to the brain, lungs and other organs. The lack of oxygenated blood can cause brain damage in only a few minutes and a person could die within 8 to 10 minutes. According to the American Heart Association, about 90 percent of people who suffer cardiac arrest at home, at work or in a public location die because they don’t receive immediate CPR from someone on the scene.
CPR, or Cardiopulmonary Resuscitation, is a lifesaving technique that is used when someone’s breathing or heartbeat has stopped. CPR, especially if performed immediately, can double or triple a cardiac arrest victim’s chance of survival.
In emergency situations, such as in cardiac arrest or drowning, the American Heart Association recommends that everyone, untrained bystanders and medical personnel alike, begin with HANDS-ONLY CPR (chest compressions without mouth-to-mouth breaths). Even if you’re fearful that your knowledge or abilities aren’t 100 percent complete, it’s far better to do something than to do nothing at all. 75% of all cardiac arrests happen in people’s homes and the difference between doing something and doing nothing could be your loved one’s life. CPR can keep oxygenated blood flowing to the brain and other vital organs until more definitive medical treatment can restore a normal heart rhythm.
HANDS-ONLY CPR consists of two easy steps and is recommended for use by people who see a teen or adult suddenly collapse in an “out-of-hospital” setting, such as at home, at work or in a public location:
The American Heart Association (AHA) states that any attempt to provide CPR to a victim is better than no attempt to provide help. Don’t be afraid to act in an emergency:
LEARN HOW TO SAVE A LIFE:
Watch a 90-second Hands-Only CPR video. Hands-Only CPR is a natural introduction to CPR, and the AHA encourages everyone to learn conventional CPR as a next step. To watch the Hands-Only CPR instructional video visit: http://bit.ly/1OZ8SAY For video in Spanish visit: http://bit.ly/2r79ksg
Watch a 22 minute video for more in depth CPR training: The AHA’s 22-minute CPR Anytime™ program ( http://bit.ly/1UFSt6n ) is a very short CPR training program that you can do at home. The video provides skills training and practice that can prepare you to perform high quality chest compressions.
Take a CPR class: Take an accredited first-aid training course, which includes CPR, rescue breaths, and how to use an automated external defibrillator (AED). CPR is a psychomotor skill. People who have had CPR training are more likely to give high-quality chest compressions and are more confident about their skills than those who have not been trained (or have not trained in the last 5 years).

Learn CPR – you can save a life!

Sleep apnea is a serious sleep disorder that occurs when a person’s breathing is interrupted during sleep. In sleep apnea your breathing passages becomes blocked, or the muscles that control your breathing stop moving. Either way, breathing stops, and then resumes with a gasp. In the worst cases, this can happen hundreds of times every night. This means the brain and the rest of the body may not get enough oxygen. And if left untreated, sleep apnea can result in a growing number of health problems, including:
Symptoms of Sleep Apnea: Sleep apnea often goes undiagnosed, as doctors usually can’t detect the condition during routine office visits and there isn’t a blood test that can diagnose the condition. Most people who have sleep apnea don’t know they have it, because it only occurs during sleep. A family member or bed partner might be the first to notice signs of sleep apnea. Signs and symptoms of sleep apnea include:
There are two types of sleep apnea:
Obstructive Sleep Apnea (OSA). The most common type of sleep apnea is Obstructive Sleep Apnea (OSA). In this condition, the soft tissue in the back of the throat collapses or becomes blocked during sleep, causing shallow breathing or breathing pauses. Oxygen levels drop when breathing slows and the body responds by releasing epinephrine (also called adrenaline), a stress hormone. When this happens over and over, adrenaline levels remain high, leading to high blood pressure. “Over time, OSA exposes the heart and circulation to harmful stimuli that may cause or contribute to the progression of most cardiovascular diseases,” explains Dr. Atul Malhotra, associate professor at Harvard Medical School and sleep specialist at Brigham and Women’s Hospital. OSA affects an estimated 15 million adult Americans and is present in a large proportion of people who have hypertension and other cardiovascular disorders, including coronary artery disease, stroke, and atrial fibrillation (irregular heartbeat).
Central Sleep Apnea (CSA): Central sleep apnea (CSA) is a less common type of sleep apnea. This disorder occurs when the area of your brain that controls your breathing doesn’t send the correct signals to your breathing muscles. CSA can be caused by a number of conditions that affect the ability of your brain-stem, the area that links your brain to your spinal cord and controls many functions such as heart rate and breathing, to control your breathing.
Who is at Risk for Sleep Apnea?
Treatment: Sleep apnea is a chronic condition that requires long-term management. Lifestyle changes, mouthpieces, breathing devices, and surgery can successfully treat sleep apnea in many people.
Lifestyle Changes: If you have mild sleep apnea, some changes in daily activities or habits might be all the treatment you need.
Mouthpieces: A mouthpiece, sometimes called an oral appliance, may help some people who have mild sleep apnea. A dentist or orthodontist can make a custom-fit plastic mouthpiece for treating sleep apnea. The mouthpiece will help keep your airways open while you sleep.
Breathing Devices: A CPAP (continuous positive airway pressure) is the most common treatment for moderate to severe sleep apnea in adults. A CPAP machine uses a mask that fits over your mouth and nose, or just over your nose. The machine gently blows air into your throat. The pressure from the air helps keep your airway open while you sleep.
Surgery: Some people who have sleep apnea might benefit from surgery. Surgery is done to widen breathing passages by shrinking, stiffening, or removing excess tissue in the mouth and throat or resetting the lower jaw.
If you, or a loved one, is having trouble breathing at night, see a doctor. Life style changes can help a person with mild sleep apnea, and in more severe cases, there are treatments that can keep the breathing passages open and normalize oxygen levels.
