The two most common ways are sedated infants and those that are born by cesarean section. Some of the other things that might cause transient tachypnea in the newborn are asthma in the mother, macrosomia of the fetus, and labor intervals that are abnormally long (www.emedicine.com,2004). The main symptoms of transient tachypnea of the newborn include a fast breathing rate, retractions, flaring of the nostrils, and making grunting sounds during breathing, although each baby may experience these symptoms differently, and have some symptoms but not all of them. Generally, this depends of the severity of the condition. Sometimes, however, the symptoms that come with the condition mimic those of other problems that may be more serious, and a proper diagnosis is essential. This is usually done with a chest x-ray, although there is still no real guarantee. The symptoms of transient tachypnea of the newborn, however, are generally always resolved by the baby's third day of life and therefore that is one sure way to assume that the diagnosis was correct (www.readinghospital.org,2005).

As for treatment for transient tachypnea...

How old the baby is, gestationally, and the medical history of the pregnancy will play a part in it, as will how serious the condition is, the expectations that are had for the course of the condition, the tolerance that the baby is thought to have for medications, procedures, or therapies that might help, and generally, the opinion or preference of the parents as long as the baby is not in any danger. Blood tests are sometimes done to see the blood oxygen level of the baby, and supplemental oxygen may be needed, as may a breathing machine that provides constant pressure and helps to keep the lungs open. If there is a chance of aspiration of food because of the rate of breathing, a feeding tube may be required (www.readinghospital.org,2005).
