isoproterenol has been researched along with Anoxia, Fetal in 4 studies
Isoproterenol: Isopropyl analog of EPINEPHRINE; beta-sympathomimetic that acts on the heart, bronchi, skeletal muscle, alimentary tract, etc. It is used mainly as bronchodilator and heart stimulant.
isoprenaline : A secondary amino compound that is noradrenaline in which one of the hydrogens attached to the nitrogen is replaced by an isopropyl group. A sympathomimetic acting almost exclusively on beta-adrenergic receptors, it is used (mainly as the hydrochloride salt) as a bronghodilator and heart stimulant for the management of a variety of cardiac disorders.

The Apgar score is a simple method of quickly assessing the health and vital signs of a newborn baby created by and named after Dr. Virginia Apgar. Apgar testing assesses Appearance, Pulse, Grimace and Activity in a newborn and is typically done at one and five minutes after a baby is born, and it may be repeated at 10, 15, and 20 minutes if the score is low. The five criteria are each scored as 0, 1, or 2 (two being the best), and the total score is calculated by then adding the five values obtained. Agar scores of 0-3 are critically low, 4-6 are below normal, and indicate that the baby likely requires medical intervention, scores of 7+ are considered normal. The lower the Apgar score, the more alert the medical team should be to the possibility of the baby requiring intervention. Some components of the Apgar score are subjective, and there are cases in which a baby requires urgent medical treatment despite having a high Apgar score. (NCT01131260)
