People who appear to be absolutely normal are talking to their families, walking around the mall, watching a game when they suddenly have a cardiac arrest. In this case the ideal is to immediately start a resuscitation maneuver and call for medical help, however, this is a difficult situation and time is extremely determinant in the patient's survival.
Many experts claim that within 5 minutes, 50% of individuals who have suffered a cardiac arrest will be dead and thereafter 10% will die with every passing minute. So when all is said and done, in ten minutes everyone will be dead. Thus, we can state that 10 minutes would be a reasonable time to consider resuscitation interruption after complete resuscitation efforts without detectable heart rate.
The subscapularis muscle usually is a large muscle positioned across the frontal area of the shoulder blade. The subscapular bursa is situated just between the subscapularis muscle and the chest wall. When there is an inflammation of this bursa it is called subscapular bursitis.
