Understanding the Myocardial Blood Requirements

-

Myocardial Blood Requirements; the heart is basically two pumps in one, one pump pumps blood into the lungs and the other pumps blood to the rest of the body.  The heart is made up of specialized muscle tissue, called the myocardium.  The myocardium requires oxygen and nutrients, just like any other tissue in the body.  However, the blood that passes through the heart’s chambers is only passing through on its trip through the body - this blood does not give oxygen and nutrients to the myocardium.  The myocardium receives its oxygen and nutrients from the coronary arteries, which lie on the outside of the heart.  When the heart tissue does not receive an adequate blood supply, it cannot function as well as it should.  If the myocardium’s blood supply is decreased for a length of time, a condition called ischemia may develop.  The heart’s primary function is to pump blood throughout the body, so that the body’s tissues can receive oxygen and nutrients and have waste substances taken away.  Like any pump, the heart requires fuel in order to work.  Ischemia can decrease the heart’s pumping ability, because the heart muscle is weakened due to a lack of food and oxygen.

Normal Range (0.192 - 0.412)

Levels:
If the Myocardial Blood requirements readings are high, can indicate that the vessels in the heart are narrowing due to excessive fats, therefore limiting the supply of oxygen-rich blood to the heart muscle.
If the Myocardial Blood Requirements readings are low, often indicates poor nutrition and a lack of adequate physical exercise resulting in insufficient oxygen and nutrients.

Management:
Maintaining a healthy level of Myocardial Blood Requirements involves the same recommendations as indicated for cholesterol and blood viscosity, diet and exercise.  Eating foods like fruits, nuts and vegetables is a great start.

Make Your Resume A Breath of Fresh Air

 As a job seeker, it’s easy to see hiring managers as big, bad obstacles that need to be overcome. They’re the gatekeepers, after all. But, this kind of thinking actually leads to weaker job applications. Think about it this way: Hiring managers read a ton of resumes —to the point at which their eyes cross. More importantly, hiring managers are just people. With this in mind, the only thing you really need to do to stand out is to have the one resume that actually lets them breathe a sigh of relief during this painful process. Here are simple things you can do. Make the First Thing on Your Resume Immediately Relevant There’s nothing worse for a hiring manager than having to dig through a resume to find what, exactly, an applicant’s relevant experience entails. Don’t make this harder than it needs to be for the person who will be reading your resume, and make sure the first thing on your resume is something you know he or she wants. Are you applying to a sales position? Tit...

Achieving Mutual Gain in any Negotiation

-

When the parties in a negotiation are committed to a position, they feel that moving from that position is a failure. Instead, the focus should be given to their purposes. To achieve mutual gain, focus should be given on interests, rather than positions. An environment of respect and discipline should be prevalent between both the parties. For example, in a school, one party favours uniforms, the other opposes it. The reasons for the first party to support uniforms is to avoid circumstances where students wear casuals, because it may give rise to an act of bullying where a person or group may act hostile towards each other regarding their individual style.  The second party is against the use of uniforms because wearing a uniform has its own drawbacks. It makes students easily distinguishable to outsiders. It might even cause financial issues for guardians with limited income. In such a case, the solution is to allow students to dress according to a specific dress code. ...

How long should my resume be?” is one of the most often asked questions about resumes. Lately, job seekers were advised that a resume should not exceed one page. Those who broke this golden rule were destined for the circular file. Times have changed, and thus has the criteria for resume length. The new guideline is: A resume should be long enough to entice the hiring managers to give you a call for an interview. That may sound vague, but there is no hard-and-fast resume length rule that works for everyone. Things to consider include career objective, occupation, industry, experience, years of experience , scope of accomplishments and education/training. Resume Format: Keep these factors in your mind when deciding on resume length: Your resume can be a career marketing strategy, not an autobiography. Do your best to keep your resume concise and focused on your key selling points. Leave out the past experiences that don’t market you to your current goal. Every word in the res...
