Left Ventricle Cardiopulmonary Interactions by Dr. Lara Shekerdemian.

So if we move on now to the ventilation of the left heart, I think the key here-- and

it's something that a lot of people have struggled with getting their heads around, but I try

and keep it simple-- is to understand the impact of transmural pressure, the concept

of transmural pressures, and then their impact on the heart.

So simply put, transmural pressure is the difference between ventricular chamber pressure

and the extracavitary pressure, which could be pericardial or pleural.

So when we breathe quietly, at atmospheric pressure or around that, our transmural left

ventricular pressure, which is equivalent to the afterload that the left ventricle sees,

is about the same as LV pressure.

If we breathe in deeply against a closed glottis-- so we perform a Muller maneuver-- or even

take a very deep breath in and make our intrathoracic pressure very negative, that produces, let's

say, an intrathoracic pressure or a pleural pressure of -20.

So the transmural pressure then becomes 140.

So that deep breath, that Muller maneuver, increases the transmural left ventricular

pressure, and therefore, the left ventricular afterload.

If, instead, we provide a positive pressure, a positive airway pressure and a positive

pleural pressure-- with positive pressure ventilation obviously-- then the transmural

pressure drops. So that's favorable to the left ventricle.

And the last schematic there just shows the impact a vasodilator would have on those transmural pressures.

So we drop the blood pressure to 100 with a vasodilator.

We then perform whatever maneuver give us the very negative pleural pressure.

And we restore the transmural pressure to 120, so around the baseline before the blood

pressure was dropped with a drug.

Linamar scholarships for women in engineering and business - Duration: 2:46.

We wanted to invest in women in engineering and Western was the perfect choice. We have a dual degree

opportunity in engineering and business, so really it has all the elements of what we were looking for.

There's so many benefits to choosing to do a dual degree with Ivey because with engineering you get the technical side.

But then with business you get the networking side the people skills you need to shape your career.

Scholarships and bursaries, they're so important to students

They help us get through the year and make things a little bit easier for us a little more flexible.

It really helps students take their future into their hands and

really say okay that I can do a degree

I can go to university because now I have the financial stability to do so. It's a great opportunity to really learn how a business

runs so I think could be an exciting opportunity for these young women

coming into our company to apply for and potentially be part of that program. I think it's gonna make

women feel valued and wanted in this industry.

I know that it could be kind of scary as a women to be going into a program like this

when the ratios are kind of off. There are very few women in engineering

especially in certain disciplines like mechanical and mechatronics

that if they had this

opportunity to do the engineering and business degree not only would it encourage them to do the dual degree

but it would encourage them to do engineering. We're trying to make it affordable and

we're trying to create a job at the end so that there's not only the opportunity for a career

but you know a straight path to one at Linamar.

I think having the double degree and

Ivey is preparing me so much better than I thought I would to be a leader

And I find that if I wasn't a part of this double degree program. I wouldn't have got that exposure

I just finished a co-op this past year, and I was working on the sales team

I was able to do a lot of the engineering stuff that they just didn't have the knowledge for. It helps so much having

experience like a co-op or an internship.

It makes your knowledge that you've learned through the eight months so much more meaningful because you're like oh like that

what this is for. I'm really excited about the program and thrilled that Western is excited about it as well

and I hope it's the inspiration for other companies to do similar things.

I think the more that we can do to bring engineering and business together

at Western the better. I'm really proud my mom loves to give back. It's awesome

I think she's instilled a spirit of giving back in a lot of people that she has led

and I'm just really proud to be involved in it at all.

The Business Case for Accessibility - Duration: 3:30.

[ Music ]

>> Louie DiPalma: I think in terms of Web accessibility, it's good for business

to understand the business case around making their website more accessible and also

to provide some simple, easy tools to achieve that outcome.

>> Jutta Treviranus: Accessible Web design saves money.

It saves the cost of creating websites because it makes them much easier

to update, much easier to navigate.

It saves in help and support because it's less confusing.

There is a myth that there are not very many individuals who require Web accessibility.

There is a myth that Web accessibility is not good for aesthetics or that it means

that it's a boring, unaesthetic website.

There are myths that it costs too much.

Those are all completely erroneous and, in fact, the opposite is the case.

You can have a website that is accessible and one that is inaccessible,

and they can look exactly the same.

>> Dr. Marie Bountrogianni: In this day and age,

marketing and disseminating information is done online and through accessible and attractive

and responsive web pages, websites.

If we do not make these sites accessible in every way, whether that means for people

with disabilities or whether that means for, quite frankly, a very sophisticated population

that is not willing to spend a lot of time trying to figure out a poor website.

Then we will be left behind.

We will lose business.

Whether you're public or private sector.

>> Louie DiPalma: When it comes to accessibility,

there's a number of reasons why organizations would want

to make their organizations more accessible.

You know, there's 15 percent, you know, one in seven Ontarians, you know, have a disability.

So if you have a more accessible whether it's a website or more accessible approach

to customer service in your organization, you're just going to reach more people.

You're going to reach more customers.

And, you know, when you factor in friends and family with persons of disabilities, you know,

that comes out to almost over 50 percent of the population.

So there is a business case there for businesses trying to reach a broader audience

and a broader customer base to make their businesses and organizations more accessible.

If an organization is trying to build an environment for inclusivity and accessibility,

it can't be done as an afterthought.

It has to be built into the daily work processes at the organization.

That's really what it comes down to so, you know, it comes down to helping organizations

through a really efficient and effective way to understand how

to make their websites more accessible.

And how they can do that as either a low cost or no cost way and in a very effective way.

Because the last thing that small business needs to do is not be able to go to one place,

get the information they need, and get the adjustments made quickly and effectively.

America denies Puerto Rico request for waiver to bring vital fuel and supplies to island - Duration: 3:50.

The Trump administration on Tuesday denied a request to waive shipping restrictions to help get fuel and supplies to storm-ravaged Puerto Rico, saying it would do nothing to address the island's main impediment to shipping, damaged ports.

The Jones Act limits shipping between coasts to U.S. flagged vessels.

However, in the wake of brutal storms, the government has occasionally issued temporary waivers to allow the use of cheaper, tax free or more readily available foreign-flagged ships.

The Department of Homeland Security, which waived the act after hurricanes Harvey and Irma, did not agree an exemption would help this time.

On Monday, U.S. Representative Nydia Velázquez and seven other representatives asked Elaine Duke, acting head of Homeland Security, to waive the nearly 100-year-old shipping law for a year to help Puerto Rico recover from Hurricane Maria.

Gregory Moore, a spokesman for Customs and Border Protection, an office of Homeland Security, said in a statement that an assessment by the agency showed there was "sufficient capacity" of U.S.-flagged vessels to move commodities to Puerto Rico.

"The limitation is going to be port capacity to offload and transit, not vessel availability," Moore said.

Puerto Rico has long railed against the Jones Act, saying it makes the cost of imported basic commodities, such as food, clothing and fuel, more expensive.

After Homeland's denial, Senator John McCain, a Republican and a long time opponent of the Jones Act, sent a letter to Duke asking why the department decided against the waiver.

He asked the department to detail the costs of shipping goods from Florida to Puerto Rico versus the costs of shipping from Florida to the Virgin Islands, which has a permanent Jones Act exemption.

"It is unacceptable to force the people of Puerto Rico to pay at least twice as much for food, clean drinking water, supplies and infrastructure due to Jones Act requirements as they work to recover from this disaster," McCain said in the letter, a copy of which was seen by Reuters.

The administration's rationale for a waiver after Harvey and Irma hit Texas, Louisiana and Florida was to ease movement of fuel to places along the U.S. East Coast and make up for temporary outages of high-capacity pipelines.

"The situation in Puerto Rico is much different," Moore said in the statement, adding that most of the humanitarian effort would be carried out with barges, which make up a large portion of the U.S. flagged cargo fleet.

Homeland did not immediately return a request for comment on the McCain letter.

Backers of a Jones Act waiver for Puerto Rico said it would help the relief effort.

"Our dependence on fossil fuel imports by sea is hampering the restoration of services," said Juan Declet-Barreto, an energy expert at the nonprofit group the Union of Concerned Scientists.

The refusal to allow the waiver "is raising fears on the island that they are going to be left behind in this disaster."

The United States shipped an average of nearly 770,000 barrels of crude oil and oil products like gasoline and diesel annually to Puerto Rico from 2012 to 2016.

Supporters of the Jones Act, including ship builders, have said it supports American jobs, including ones in Puerto Rico and keeps shipping routes reliable.

US expected to lift shipping restrictions for Puerto Rico hurricane relief - Duration: 6:02.

US expected to lift shipping restrictions for Puerto Rico hurricane relief

Ricardo Rosselló said Wednesday he expected the federal government to waive the Jones Act, which would lift restrictions on ships that can provide aid to the island ravaged by Hurricane Maria.

He said he has been speaking with members of Congress on both sides of the aisle who have supported an emergency waiver.

We expect them to waive it, Rosselló told CNN, noting that there was a seven-day waiver after Hurricane Irma, which was much less damaging to the US commonwealth.

On Tuesday, Team Trump denied a request to waive shipping restrictions to help get fuel and supplies to Puerto Rico, saying it would do nothing to address the islands damaged ports.

A waiver would allow Puerto Rico to get assistance not only from American ships but from any vessels that can bring supplies to the island's 3. 4 million people, Reuters reported.

That is critical, particularly for fuel, Rosselló said. One of the consideration right now is the priority of getting fuel, diesel, gasoline, all across the island. Right now we have enough fuel.

"Were limited by the transportation logistics, but at some point of course, getting fuel into the island is going to be critical so that we can have the major functions of telecoms, hospitals, water, to be running appropriately," he added.

The Jones Act requires that all goods shipped between US ports to be carried by American owned-and-operated ships.

The category 4 storm slammed into Puerto Rico on Sept. 20, killing at least 16 people, inflicting catastrophic damage and leaving nearly all of the island without power.

About 97 percent of the islands residents were still in the dark Wednesday, Rosselló told CNN. About half of them have no running water.

On Wednesday, 3,500 pounds of water, military meals ready-to-eat, diapers and other supplies will be flown from Miami to Puerto Rico, Rob Brisley, a spokesman with US Customs and Border Protection, told CNN.

We are getting help from the federal government, but this is an unprecedented set of circumstances, Rosselló said Wednesday. We want to make sure that we recognize that a lot of resources are coming in.

They are coming in by air or by boats. But they are starting to execute.. Meanwhile, a group of top US electric company executives said the island faces a long, complicated power restoration process.

Damage assessments must be done to determine what human and equipment resources will be required to restore power, the CEO-led Electricity Subsector Coordinating Council said in a release, Reuters reported.

The ESCC is coordinating the power restoration efforts between the US government and the electric power sector.

Its members include the American Public Power Association, which represents companies like the Puerto Rico Electric Power Authority, which serves all 1. 5 million electrical customers on Puerto Rico.

We thank President Trump for authorizing 100-percent cost sharing by the federal government for 180 days of emergency work to help begin the process of repairing damaged energy infrastructure, said APPA chief Sue Kelly, Reuters reported.

Trump — whose administration was mostly praised for its response to hurricanes that battered Texas and Florida — has come under fire for his slow response in Puerto Rico during days of tweeting about the NFL.

When he finally turned his attention to the devastated island, he appeared to blame its plight on internal turmoil, as well as its "massive debt" to "Wall Street and the banks which, sadly, must be dealt with.

On Tuesday, Trump offered an excuse for why aid has been slow to arrive on the island. "It's very tough, because it's an island," Trump said during a meeting with members of the House.

"In Texas, we can ship the trucks right out there. And you know, we've gotten A-pluses on Texas and on Florida, and we will also on Puerto Rico," he said.

"But the difference is, this is an island sitting in the middle of an ocean. And it's a big ocean; it's a very big ocean. And we're doing a really good job.".

He later announced that he will visit Puerto Rico, as well as the US Virgin Islands, on Tuesday – saying it was the earliest he could get there without affect recovery efforts.
