Doctors determined that babies born at 37 weeks have an increased risk of health problems due to insufficient development. Premature babies may need medical attention to help with respiration, until their lungs fully develop. They may also need to have extra protection from germs, because their immune systems may not be functioning. I would also expect that premature babies weigh less than full-term babies.

the ems is the abbreviation for the emergency medical services. it is a service provided by a group of medical professionals specialised doctors and other healthcare staff.

any one can call 911 in case of any medical emergency and a group of health care professional will come and give the treatment required. every day the ems staff receive many phone call, which are related to different types of medical emergencies, out of which 25-28% are exclusively related to the respiratory issues.

so, the correct answer is 25-28%.
