Gay Cruising Areas North New Jersey




The BLS (basic life support) is important because early intervention: early cardio-circulatory arrest, the average probability of survival decreases by 7-10% every minute, even after 90-10 min. In the absence CPR (Cardio-Pulmonary Resuscitation acronym), it is very difficult if not impossible to hope for the recovery of anoxic brain damage definitive (but the first serious damage to the brain are found already after 4 minutes of lack of oxygen) ... EARLY INTERVENTION CAN 'save a life.

News: The Basic Life Support BLS also known by its acronym, is a technique of first aid that can - in certain circumstances - be decisive in saving the life of a victim. For injured patient means many conditions, a person is unconscious (unconscious person), or a person with a mechanical lock of the airways (objects in the throat of children, in subjects water drowning), the person subjected to electric shocks or in multiple trauma with fractures of the road (often to the coast), and finally to the patient in total cardiac arrest with temporary coma.
The technique known as the BLS, which includes cardiopulmonary resuscitation (CPR) is included in the sequence of basic support to the vital functions. The definition
BLS / D refers to the BLS protocol with the addition of didefibrillazione procedure (which is the standard sequence in training for lay rescuers).
function
The purpose of this maneuver is to keep oxygenated brain and heart muscle, by blowing air into the lungs and causing artificially, by compressive forces on the chest, a minimum of blood circulation.
The main risk related to the lack of rescue in these cases is anoxic brain damage, is being held in this regard that the oxygen (necessary precisely to the brain) is present in the environment-average percentages of 21%, while the air exhaled from the lungs is about 16% (ie, breathing, consuming only about one quarter of the oxygen in the air, and this means that - theoretically much - the same air can be breathed no more than 4 times), this finding helps us understand how the intervention with simple artificial respiration (mouth) rather than with artificial respiration evolved (self-expandable balloon, bottle oxygen, advanced emergency) can really make a difference, since practicing the traditional CPR, the rescuer insufflerà air in the lungs of the victim whose oxygen has already been partially used (because the rescuer has that air inhaled and exhaled) , and so will be less effective than air.
Equally important is the timeliness of intervention: the beginning cardio-circulatory arrest, the average probability of survival decreases by 7-10% every minute, even after 90-10 min. in the absence of CPR (which stands for Cardio Pulmonary Resuscitation), it is very difficult if not impossible to hope for the Recovery of anoxic brain damage definitive (but the first serious damage to the brain are found already after 4 minutes of oxygen deprivation).
