The human body is mostly made up of water (H2O), and there is one oxygen atom in each molecule of water. Note that, although each water molecule also contains two hydrogen atoms, the atomic mass of hydrogen (about 1) is much smaller than the atomic mass of oxygen (about 16). Because of this, hydrogen contributes less to human body mass than oxygen.
Bradycardia is the most ominous sign of impending cardiopulmonary arrest in infants and children.
Bradycardia is a slow heart rate. The hearts of adults at rest usually beat between 60 and 100 times a minute. The heart beats fewer than 60 times a minute.
Bradycardia can be a serious problem if the heart rate is very slow and the heart can't pump enough oxygen-rich blood to the body. If this happens, one may feel dizzy, very tired or weak, and short of breath. Sometimes bradycardia doesn't cause symptoms or complications.
Cardiopulmonary arrest is the cessation of adequate heart function and respiration and results in death without reversal.
