Yes, surgeries are pretty much entirely wired. Hospitals are conservative entities, and adopt new technology like wireless slowly and carefully -- intereference between devices can mean life or death. Video particularly is mostly copper based, since any loss of resolution (there's that word again) or time delay between a surgeon's movements and the picture on the monitor is unacceptable, both of which can occur with wireless video as it usually is implemented today.
Additionally, many (most?) video systems in ORs are on mobile carts, completely independent of any servers or permanently-installed monitors. A camera, light source, recorder/printer and monitor all reside together in a cart to be moved rapidly from OR to OR as needed. A single power cable is plugged in, and it's ready to use. A second, coax video, cable could extend to a built-in video system if wider viewing or monitoring is required. Very little compelling need for wireless links.
AJ2X - I'm not getting you wrong at all. I definitely get what you're saying. It's unfortunate that you've labeled my post a "shill comment". I prefer positive and respectful.
I stand by my comment that the article is a good one. What Charles wrote is sound. Many articles here are based on press releases. Each also gives a little more information to provide a bigger picture and encourage inquisitiveness. That's a good thing.
Agreed, that many articles here are indeed based on press releases, though I expect (I hope not unreasonably) those press releases to be at least looked at and vetted for technical rigor and not just passed along as fact.
Also agreed, that encouraging innovation and inquistiveness is a Good Thing. Having one's expectations raised by overenthusiastic and uncritical PR is, however, a waste of valuable engineering time.
We'll just have to disagree on whether this is "good article."
The question of whether engineers could have foreseen the shortcut maintenance procedures that led to the crash of American Airlines Flight 191 in 1979 will probably linger for as long as there is an engineering profession.
More than 35 years later, the post-mortem on one of the country’s worst engineering disasters appears to be simple. A contractor asked for a change in an original design. The change was approved by engineers, later resulting in a mammoth structural collapse that killed 114 people and injured 216 more.
If you’re an embedded systems engineer whose analog capabilities are getting a little bit rusty, then you’ll want to take note of an upcoming Design News Continuing Education Center class, “Analog Design for the Digital World,” running Monday, Nov. 17 through Friday, Nov. 21.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
