Hi,
I am a Pediatrician. An APGAR of 7-10 does not require any intervention. A score of 4, 5, or 6 requires immediate intervention, usually in the form of oxygen and respiratory assistance, or perhaps just suctioning if there has been any nasal / oral obstruction. While suctioning is being done, a source of oxygen may be placed near the newborn's nose and mouth.
With a score of 0-3, the newborn is unresponsive, apneic, pale, limp and may not have a pulse. Interventions to resuscitate will begin immediately. This wil linclude airway support after properp positioning and suctioning including intubation, and cardiac massage. Use of drugs like adrenlaine maybe inidcated in case of a failure to resuscitate,
regards
Dr. Gupta
