Watch: 'Time is absolutely crucial' – new app aims to save precious seconds after person suffers cardiac arrest

Only one in six people suffering from cardiac arrest in New Zealand will survive, but a new app called GoodSAM is hoping to change that.

Wellington Free Ambulance's Vanessa Simpson says the GoodSAM app is a play on 'Good Samaritan', but it also stands for 'good smartphone-activated medic'.

"Essentially, it alerts people who register and sign up on that app to a cardiac arrest that's happening within a kilometre radius of them," Ms Simpson said.

The app works by sending an alert to a registered member's phone.

If the alert is accepted, the location of the person in need is received and the user can then find them and perform CPR.

St John's Tony Smith says the first five minutes after a cardiac arrest is the most crucial.

"If a person gets CPR and the use of an AED or defibrillator in the first five minutes, their chance of surviving is more than doubled and that's why the use of bystanders is so crucial to outcomes following cardiac arrest," Mr Smith said.

The app also shows the location of the nearest defibrillator, which is just as crucial as CPR.

"It's crucial because CPR causes blood to flow around the body but it won't start the heart on its own, and a heart which has stopped beating needs both CPR and a defibrillator in order to be restarted," he explained.

GoodSAM sends an alert to the mobile phone of people who sign up, pointing them in the direction of people in desperate need. Source: Seven Sharp

The korowai, a traditional Maori cloak, was loaned to Ms Ardern by the Ngati Ranana London Maori Club.

The Spinoff Atea's Leonie Hayden tweeted, "I try not to publicly fawn over our PM, not cos I don't respect the hell outta her, I'm just terrified of being wrong about her (politicians gonna politician). But for some reason this image makes me tear up a little."

Another Twitter user, Jess Berentson-Shaw, wrote, "Perhaps one of the features of the image that gives people pause is the subversion of what power is & particularly what it has not been. Here is a woman in power who is hapu. Eurocentric cultural stories of power tell us its [sic] the opposite of power. The visual says wanna bet?".

The prime minister made a speech to members of the Commonwealth during the dinner, held at Buckingham Palace.


Watch: Big surprise for the inspiring big sister who raised seven siblings, got an education and a new job

Jesse Te Iri Haturini, who left her job at 25 to look after her seven siblings, has been showered with gifts from viewers after her story first aired on Seven Sharp earlier this month.

Jesse has received $1000 "for hair, nails, spa [and] good times" from a family in Wellington.

"I love that. I need my hair done. I love nails and I've never, ever had that. Thank you to this family," Jesse said between tears.

Jesse's family also received a day pass to Rainbow's End, a free dental care voucher from "an Auckland dentist who loves your story" and $2000 worth of luxuries "from a Christchurch family who thinks you're awesome".

The family also received a table from Big Save Furniture so they could all fit around the dinner table.

"Wow, I'm speechless. I'm overwhelmed and I'm very, very grateful for everything," Jess said.

When the story first aired, the children were in care but were not adjusting well.

"I was quite surprised that they couldn't really read, couldn't really count," Jess said.

"I didn't do it for recognition or anything, just did it out of love. And, yeah, I feel proud. People say you should be proud of yourself. I'm proud of them."

Now 31, Jesse has begun working full-time again as a stock controller, while also running the home.
