The Labour leader says David Cameron puts the wrong values at the heart of the NHS and the future of the health service is at stake in the general election. "Let's go out and fight for it." he says.
Mr Miliband says people in their 70s and even 80s are currently waiting hours for ambulances to arrive, getting stuck outside hospital in ambulances because A&E is full, and lying on trolleys in corridors. It is an NHS "without enough time to care", he says.

The Labour leader says the country faces a choice of two futures - continuing with a Conservative plan, which has led to an "NHS in crisis" and "threatens the service as we know it". Or a Labour plan to "rescue" the NHS, invest in its future and join up services from home to hospital.
Ed Miliband says the "precious" institution faces its "most perilous moment in a generation".
Ed Miliband is now delivering a speech on the NHS in Trafford, Manchester.

The ONS's chief economist, Joe Grice, tells the BBC News Channel it's "too early to say" if this slowdown will persist. "The dominant services sector remains buoyant while the contraction has taken place in industries like construction, mining and energy supply, which can be erratic," he says.
A breakdown of those GDP figures. The dominant services sector, which represents more than three quarters of output, grew by 0.8% - meaning services are now 7.9% ahead of their pre-downturn level at the start of 2008. Growth was dragged down by construction, which contracted by 1.8% - its worst slowdown since the second quarter of 2012.
But the 0.5% growth in the final three months of 2014 represents a slight slowdown from the previous three months, which saw 0.7% growth.
To put that 2.6% figure in context, that's the UK's best annual growth since 2007. In 2013, the economy grew by 1.7%.
Reacting to those GDP figures, Chancellor George Osborne says they confirm the recovery is "on track". "Our plan is protecting Britain from the economic storm, with the fastest growth of any major economy in 2014. But the international climate is getting worse, and with 100 days to go until the election now is not the time to abandon that plan and return Britain to economic chaos," he says.
BBC's business correspondent Ben Thompson says the ONS GDP figures are good news, but not as good as was expected. The services industry is doing quite well, but construction is dragging it down, he says.
ONS says UK economy grew by 0.5% during the fourth quarter of 2014 and by 2.6% over the year.
The parties are ramping up their campaigns - and with 100 days until people go to the polls, the BBC's Jo Coburn highlights some key dates between now and then.
Here's a bit more on who said what on the TV debates this morning - and whether a deal is any closer. The latest proposal from the broadcasters suggested a seven-way debate between the leaders of the Conservatives, Labour, the Liberal Democrats, UKIP, the Greens, the SNP and Plaid Cymru on the BBC and ITV.
Get the expert analysis behind the election pledges. The BBC's Health Editor Hugh Pym blogs on Labour, the NHS and social care integration and the editor of the BBC's Political Research Unit David Cowling explains why this general election is impossible to call.

BBC Assistant Political Editor
Norman Smith says with 100 days to go until the election, the main parties are sticking to the themes they've stuck to for weeks - Labour on the NHS, and Tories on the economy. He says there are a couple of new nuggets from David Cameron though - a hint he's minded to continue protecting pensioner benefits such as bus passes and winter fuel allowances, and a view that Northern Ireland should be included in TV debates.
Nick Robinson
Political editor
Nick Robinson says David Cameron doesn't want to be seen to be saying "no" to the TV debates - but he's not exactly saying "yes" either.
BBC Breakfast
The Labour leader says "Britain can do a lot better" and his party wants to put working people first. "This is a big election, and I'm going to fight for it," he says.

David Cameron says you can't include SNP and Plaid without having parties from Northern Ireland. He says that he initially was making the point that the Greens should take part, but the broadcasters have gone further. He says he had also had concerns about the debates taking place during the election campaign itself - he thinks they dominate the campaign too much.
