I guess we need to look at the answers here. And I think for menopause, when timing is important. So, classically and medically, menopause is defined as the absence of menstrual cycles for a period of one year. But perimenopause is that years before, maybe up to 10 years, classically around five years, of hormonal changes. And that's like I said, it's typically characterized by this fluctuation of estrogen levels, either in an estrogen dominant picture or in a low estrogen and progesterone picture. So once you hit menopause, if you've been characterized medically or by yourself as not having menstrual cycles for about a year, you could probably make the decision, meaning you're going to have categorically very little circulating estrogen, estrogen and progesterone.Pediatric cardiopulmonary arrest is characterized by unresponsiveness and failure to breathe normally (with only an occasional gasp), and is most often the end result of apnea or respiratory failure leading to bradycardia and then pulseless electrical activity or asystole.
Hypoxia and ischemia (asphyxia) progress rapidly over 4 to 10 minutes.
Sudden cardiac arrest due to arrhythmia (ventricular
malaysia email list fibrillation/tachycardia) is much less common in children than in adults, except in special resuscitation circumstances such as commotio cordis (sudden forceful blow to the chest) or congenital heart disease or prolonged QTc interval.
Cardiac arrest in infants and newborns is almost always the result of respiratory failure or airway obstruction, with SIDS being the most common cause of death in children younger than 6 months of age.

Clinical features
Apnea, unresponsiveness, and unresponsiveness to verbal or physical stimuli characterize pediatric cardiac arrest. Other than occasional gasping, respiratory effort is rarely present. The pupils are usually fixed and maximally dilated, and myoclonic jerks or convulsions with hypoxia may be seen before or immediately after return of spontaneous circulation.
