Patrick Bouvier Kennedy

The infant was quickly baptized, named Patrick after his great-grandfather Patrick Joseph Kennedy (1858–1929).

He was given the middle name of Bouvier after his mother's maiden name.

The president was allowed to wheel the baby in an incubator to the First Lady's bedside.

James E. Drorbaught, the pediatric specialist at Boston Children's Hospital, was flown by helicopter from Boston to consult on his case, and he recommended transfer to Boston.

Five hours after birth, the infant, accompanied by Dr. Drorbaught, was rushed by ambulance to Boston Children's Hospital, 70 mi away, in under 90 minutes.

The transfer to the hospital in Boston was initially reported as a "precautionary measure," the White House said.

The baby's condition was accurately reported as HMD, but it was also reported that it would take at least four days to assess his condition and that he was being given medication to assist his condition.

At the time, all that could be done for a baby with hyaline membrane disease was to keep the patient's blood chemistry as close to normal as possible.

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."

Kennedy died at 4:04 a.m. on August 9 "despite a desperate medical effort to save him" and had lived 39 hours and 12 minutes.

At the time of the infant's death, the president was outside the room with the hyperbaric chamber with his brother, U.S. Attorney General Robert F. Kennedy.

The first lady, then 34, remained at Otis Air Force Base Hospital recovering from the caesarean section.

She had suffered a miscarriage in 1955, followed the next year by a stillborn Baby Girl that the Kennedys planned to name Arabella after a ship with that name.

Two healthy children followed: Caroline in 1957 and John Jr. in 1960.

As John had also been premature, she asked her obstetrician, John W. Walsh, to accompany her when she and her children spent the summer in Hyannis Port, Massachusetts.

The nearby Otis Air Force Base Hospital had also prepared a suite for her in case it was necessary.

On the morning of Wednesday, August 7, Jackie took Caroline and John Jr. for a pony ride in Osterville, Massachusetts.

While the children were riding, Kennedy felt labor pains.

Walsh was summoned, and they were taken by helicopter to Otis Air Force Base.

President Kennedy was at the White House at the time.

August 7 was the 20th anniversary of the day that the US Navy had rescued him in World War II after he had spent five days marooned on an island in the Pacific.

Kennedy had been in command of Motor Torpedo Boat PT-109 when it was rammed by a Japanese destroyer, killing two of his crew.

His heroics had helped launch his political career.

PT-109 and August 7 were never far from his mind, and he kept a scale model of the boat on a shelf in the Oval Office and each day used a metal tie clasp shaped like a torpedo boat, with PT 109 stamped across its bow.

"All of which may explain why Kennedy's friend and fellow World War II naval veteran Ben Bradlee is certain that when the president's secretary, Evelyn Lincoln, hurried into the Oval Office at 11:43 a.m. on August 7, a Wednesday, to report that Jackie had gone into premature labor on Cape Cod, there was "no way in God's earth" that he did not think, My child is being born 20 years to the day when I was rescued, a coincidence providing an additional emotional dimension to a day that would be among the most traumatic of his life."

The caesarean section was performed by Dr. Walsh, who had also delivered Mrs. Kennedy of John Jr. in 1960.

Patrick Bouvier Kennedy (August 7–9, 1963) was the youngest child of United States President John F. Kennedy and First Lady Jacqueline Kennedy.

His elder siblings were Caroline, John Jr., and Arabella.

Born prematurely, Kennedy lived just over 39 hours before dying from complications of hyaline membrane disease (HMD), after desperate attempts to save him failed.

His infant death left the first family and nation in mourning.

However, it also brought HMD, now known as infantile respiratory distress syndrome, into the public consciousness, inspiring further research.

In August 1963, the 34-year-old Jacqueline Kennedy was in her third year as first lady and in the third trimester of her fifth pregnancy.

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 infant's birth weight was 4 lb. He was the first child born to a serving U.S. president and first lady since the 19th century.

Shortly after birth, Kennedy developed symptoms of hyaline membrane disease (HMD), now 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.
