Fainting, or syncopes, are relatively common, but fortunately they tend not to be anything serious. Syncopes occur when you lose muscle tone and consciousness briefly for a period of time that can range from a few seconds to a few minutes. In real syncopes, recovery does not require CPR or another method of resuscitation.
Although syncopes have a variety of causes, three of them are usually more common: blood vessel dilation, orthostatic hypotension, and heart problems. When your blood vessels dilate or expand, your blood pressure decreases. Consequently, the circulation of blood to your brain decreases, resulting in the loss of consciousness. This is the most common cause of syncopes. Stress, coughing and even urinating can trigger the dilation of blood vessels. Before fainting, you may experience a change in skin color, nausea, sweating or a rapid heartbeat.
The second cause, orthostatic hypotension, occurs when your blood vessels fail to contract after switching from lying on your stomach to a vertical position, thus lowering your blood pressure. This type of syncope is common in older people, patients with long-term diabetes and people who take certain medications.
You may also experience syncope if you have problems with your heart rate or if your heart has a structural problem that impedes blood flow.
If you notice that someone has fainted, the first and most important step is to seek medical attention.
Although syncope has a rapid recovery time, there may be other reasons for loss of consciousness, such as seizures, a heart attack or stroke, which are medical emergencies. These situations require urgent medical attention.
If the person stops breathing or their heart stops, this is not a syncope. The condition requires medical attention and the initiation of basic life support, including CPR, which includes helping breathing, chest compressions, the use of a defibrillator and other interventions. You can learn these medical interventions by taking a first aid course, such as those approved and taught at the American Heart Association.
If you develop the early symptoms of a syncope, such as a feeling of lightness in the head, then lie down and elevate your legs to encourage the circulation of blood to your brain. Alternatively, lean forward with your head between your knees. Tightening the muscles of the legs and arms can also be helpful.
If you are with a person who loses consciousness and is a true syncope, meaning that he is still breathing and his heart is beating, then put it on his left side.I should recover consciousness in a short period of time.
Syncope episodes should be monitored by a medical professional. The long-term medical management of fainting depends on the cause, and may include avoiding factors that cause them, changing medication or using a pacemaker in the heart.
