i need to know what the extension of philips medical cd for heart speculum surgery video?

We Answered:

Most medical book CDs are self-starting, and open to a menu of resources. Then, the CD will play videos from that self-started menu. You may need a code or password from the book to run the CD.

Is it possible for a high school student to observe a surgery?

We Answered:

I would assume that it's possible. It may be difficult to get done but asking can't hurt. I'd suggest you find the website of a local hospital and see if you can locate the email of one of the surgeons. The Chief of Surgery would be best as they'd probably be the one that has to give the ok.

Write a short email, since they're likely extremely busy, and ask how you'd go about getting the permission or if it would even be possible. Introduce yourself, mention your interest in a career in medicine and keep your questions to the point also. Since you want to go into medicine anyway you'll be making great contacts that will be able to write you some impressive letters of recommendation for med school when you get to that point.

If one hospital turns you down then try others. You may also try asking your family doctor. They may not do surgery themselves but likely they either work part time at a hospital or know another doctor who does. You could also try emailing the hospital administrator and see what they say.

If by chance you can't find an email address for someone that would be able to get you in, you can always send an actual letter directly to the hospital. Just address it to the hospital administrator and explain yourself as you would in your email. This may actually be more impressive to whoever receives it as it shows you put some actual time into it rather than just writing a quick email. It also appears more professional.

One last suggestion: most, if not all, med schools require a strong sustained interest in medicine from the applicant. Being able to say you witnessed a surgery is excellent, particularly since you're doing this of your own initiative rather than being invited by someone you know, but afterword you should see if you can get some volunteer work. It doesn't have to be anything hard and it doesn't have to be long hours but it does have to be something that involves medicine so try to get volunteer work where you're interacting with the patients in some way.

Good luck!

In surgery, how do they keep the blood from gushing out?

We Answered:

Well, it does ooze out. To keep it from gushing, they avoid cutting into arteries which have blood under pressure. Veins are not under so much pressure so the blood there oozes out. Also, blood vessels are clamped or burned (cauterized) to stop bleeding as well as with the application of gauze with anti-clotting chemicals. There is irrigation then suction to remove excessive oozing blood. Your body may also try to stop bleeding by its own clotting and vasoconstrictive mechanisms.

Furthermore, surgery is done in a controlled manner to control bleeding as the surgery proceeds. Sometimes a major blood vessel is accidentally cut and you get a gush, but then the surgeon must work quickly to stop the bleeding. In major heart surgery, a bypass machine is used.
Of course, if there is a major loss of blood, then the patient receives blood transfusions and fluids. Jehovah's Witnesses don't agree to take blood transfusions, so they may die with major blood loss.

On another note,the anesthesiologist can control bleeding a little by keeping the blood pressure down a little or giving blood vessel constricting intravenous medications.

I can tell you that the worse experience I ever had in surgery (assisting) was a patient who had ruptured his abdominal aorta and had alot of bleeding. He died.

Why does my body generate interference with a microphone/PA system?

We Answered:

Do post the video. I can think of two possibilities. If the "different tones of interference" that you're talking about is all different variations on AC hum, then the mic and/or cable is not adequately shielded, and your body is acting as an antenna that affects how it picks up the ambient electrical noise.

The other possibility is that the PA is feeding back (or just on the edge of feeding back), and the proximity of your body to the mic changes the resonance of the feedback system.

Could be a bit of both, I s'pose.
