This is a rare cases, a newborn baby may have no or very poor breathing because they have received little or no oxygen due to a problem during labour, delivery, or immediately after birth. Initially, when a newborn baby is deprived of oxygen, their breaths will become fast and shallow. If the situation continues, they will stop breathing entirely, their heart rate will fall, and they will lose muscle tone. It is possible to revive the newborn baby at this point with simple stimulation and exposure to oxygen. However, if the newborn baby continues to be deprived of oxygen, they will start to gasp deeply, and then they will stop breathing again. their heart rate, blood pressure, and muscle tone will continue to drop, and they will die unless they are promptly resuscitated. There is also the risk of brain damage if not enough oxygen reaches the brain. If a newborn baby is not breathing, or has very poor breathing, they must be resuscitated immediately.
