A terrified mother saved her four-week-old baby with the help of a “brilliant” ambulance call handler who helped her perform mouth-to-mouth resuscitation on her dying son.

Jasmin Legg, 39, from Lent Green Lane in Burnham, was horrified when she discovered four-week-old Zachary lying cold, blue and floppy in his cot after he suddenly stopped breathing.

She frantically dialled 999 and was put through to Darren Bradley, who works for South Central Ambulance Service (SCAS).

In heart-breaking audio footage of the conversation between Mrs Legg and Darren, the panicked mother can be heard saying: “My baby has stopped breathing. He’s lifeless.”

Darren told her to cover Zachary’s nose and mouth with her own mouth and breathe into him.

She carried on performing CPR until he began to breathe independently, eight minutes later.

Jasmin has released audio footage of the fraught conversation between her and call handler Darren.

She said: “Zachary had a cough and a cold and his older brother Joshua had it the week before. I took him to the doctor who noticed mucus on his chest, but said to sit it out.

“On the Friday morning I didn’t think he looked well but his temperature was 32.7 Celsius - which I now know is dangerously near death.”

Jasmin called her GP and was told to take the baby to A&E, but then Zachary turned blue.

She said: “When I looked at the baby he just looked blue and he flopped in my hands. I thought he was dead."

In a state of panic, Jasmin dialled 999.

She added: “It was the longest eight minutes of my life. Darren was brilliant, he was constantly guiding me, as I have never done CPR before. He saved Zachary.”

Paramedics were able to raise Zachary’s breathing from five breaths a minute, to 28.

Zachary was then rushed to Wexham Park Hospital for treatment, before being transferred to Southampton Hospital’s intensive care unit.

He was diagnosed with a serious case of bronchiolitis, a respiratory tract infection and kept in ICU for a day there before being moved to John Radcliffe Hospital in Oxford.

He is now happy, healthy and back home.

Jasmin added: “It’s very common in babies, but it’s rare to have it to Zachary’s extent.”

She was delighted when her husband David, 41, arranged a surprise meeting between her and Darren, who helped save her son’s life on November 24.

Grateful Jasmin added: “It was really nice to meet Darren and say thank you, as these people don’t get enough thanks for what they do.

“I saved his life and by doing what they told me, the mucus was blown away from whatever it was blocking.”
