While his father was aboard
Air Force One, the infant Kennedy was born by
emergency caesarean section at 12:52 p.m. on August 7, 1963, at the
Otis Air Force Base Hospital in
Bourne, Massachusetts, five and a half weeks prematurely. The caesarean section was performed by Dr. John W. Walsh, who had also delivered John Jr. in 1960. The infant's birth weight was . He was the first child born to a serving U.S. President and First Lady since the 19th century (third overall after
Esther (1893–1980) and Marion Cleveland (1895–1977) during the
second presidency of Grover Cleveland). Shortly after birth, Kennedy developed symptoms of hyaline membrane disease (HMD), later called infant respiratory distress syndrome (IRDS). It was detected by breathing difficulties within minutes. The president arrived, saw his son in distress, and sent for a chaplain. The infant was quickly baptized, named Patrick after his great-grandfather
Patrick Joseph Kennedy (1858–1929), and was given the middle name of Bouvier after his mother's maiden name. Led by Dr. Drorbaught, who stayed awake the entire time, the hospital tried everything possible to save the infant's life. The baby was given
hyperbaric oxygen therapy (HBOT) in which he was placed in a
hyperbaric chamber filled with 100% oxygen and pressurized to greater than one atmosphere. At the time, the treatment was revolutionary;
The New York Times described it as "one of the newest interests of medical researchers." ==Death and funeral==
