It is something we take for granted in the United States. A woman enters the hospital to give birth and she emerges a couple of days later with a beautiful bundle of joy.
That is how it usually goes. But this story is about the rare exception -- women who die within 42 days of childbirth. In the health care community it's called simply "maternal mortality." And in the U.S., many experts believe it is on the rise.
According to the World Health Organization, the U.S. ranks behind more than 40 other countries when it comes to maternal death rates, with 11 deaths per 100,000 pregnancies when measured in 2005. More women die in the U.S. after giving birth than die in countries including Poland, Croatia, Italy and Canada, to name a few.

A new report out of California found the number of women who died in the state after giving birth has nearly tripled over the past decade, from 5.6 deaths per 100,000 to 16.9 per 100,000 in 2006. The report was commissioned by the California Department of Health but has not yet been publically released. ABC News first learned of its existence from a watchdog group called "California Watch."
Death after childbirth is still rare, but experts say many of those deaths could have been prevented.
"We've been able to double-check the data so we can truly say there is a rise," said Dr. Elliott Main, chairman of the California Maternal Quality Care Collaborative, which worked on the report.
"Most women died from hemorrhage, from deep vein thrombosis or blood clots, and from -- this is the surprise -- from underlying cardiac disease," added Main.
The Joint Commission, the leading accreditation and certification group in the United States for hospitals, issued an alert Jan. 26, 2010 stating that "current trends and evidence suggest that maternal mortality rates may be increasing in the United States."
"As many as half of maternal deaths are preventable," said Dr. Mark Chassin, president of the Joint Commission. "The rate of maternal death today is not acceptable in the United States. We need to work much harder than we have been to reduce it."
In some cases, the chances of maternal mortality rise simply because important warning signs are missed. Jim Scythes knows first-hand how important those warning signs are and how tragic the consequences of missing them can be.
"I just think it's unbelievable that in our country today people still die of childbirth," said Jim Scythe. "I had no idea that anything like that could've happened when we went to the hospital that Friday morning."
It was March of 2007. Jim's wife Valerie had a scheduled cesarean section that seemed to go well. Their daughter Isabella was born.
But by the next day, Jim started to notice clues that all was not well. He says his wife's legs felt hard to the touch.
"She sat in her bed for 30 hours after her surgery and then got herself up and collapsed," Scythe said.
A blood clot in Valerie's leg had moved to her brain and caused a stroke. She later died.
"I look at Isabella and I think 'you're never gonna know how wonderful your mother was,'"Jim says now. "We all feel robbed."
