Shoppers and passers-by were humming the Bee Gees song Staying Alive as they practiced their compressions on a dummy under the watchful eye of Bendigo paramedics.

Advanced life support paramedic Laura Lally said the 1970s hit was a common teaching technique.

"It is a great, easy way to remember it and make sure you are getting the right compressions," she said.

"That's what we've been teaching people who are willing to have a go.

"Hum the Bee Gees and you'll be right on the money."

The paramedics were offering tips on performing the correct CPR technique to educate people and also thank the community for their support during the ongoing union negotiations.

Ms Lally said it was important for people to know CPR in case ambulances couldn't attend scenes straight away.

"There is potentially a waiting time of 25 minutes," Ms Lally said. "So we are teaching the community how to keep someone alive until we get there.

"A lot of people have been getting involved today which is good."

Ms Lally said knowing how to correctly perform CPR could be the difference between life and death.

"The longer people wait for CPR to get started, the less their chances are of surviving," she said.

"(Instances where CPR is required) could happen anywhere, at anytime and to anyone.

"That's why people need a basic understanding (of CPR)."

Ms Lally said waiting on ambulances and paramedics to arrive could be dangerous to someone's life.

"Some people are fearful of commencing CPR because they are not sure what they are doing," she said.

"So they wait until we arrive which, sometimes, can be too late."

Member for Bendigo West Maree Edwards took time to brush up her skills.

"These hard-working paramedics are taking time to teach people CPR," she said.

"They do a great job when they are out in the field and are some of the most dedicated professionals in Bendigo."
