Final answer:
In an infant, if the heart rate is 100 beats per minute or less, high quality CPR should be started. High quality CPR involves chest compressions and rescue breaths. Emergency medical assistance should be called if unsure or if the heart rate is below 60 beats per minute.
Step-by-step explanation:
In an infant, if the heart rate is 100 beats per minute or less, high quality CPR should be started. This means performing chest compressions and rescue breaths to help circulate oxygenated blood to the baby's vital organs.
High quality CPR involves pushing down on the baby's chest at least one-third to one-half the depth of their chest at a rate of around 100-120 compressions per minute. After every 30 compressions, give two rescue breaths to provide oxygen to the infant.
If you are unsure of the correct technique or if the baby's heart rate is below 60 beats per minute, immediately call for emergency medical assistance.
