Hi! I'm a second year MSECE student with a focus in bio-signal processing. I graduated from Georgia Tech with a BSEE and a minor in BME. I currently am a GRA at GTRI's Human Systems Engineering group, developing algorithms for facial tracking diagnostics and fMRI image processing. In my spare time, I enjoy swimming, playing my violin and painting.

While I have several family members that went to the ER, I have (luckily) never been inside the ER before (or anywhere near it, in fact). Instead, I would like to comment on a few things mentioned in the class lecture today. During Dr. Cowan’s lecture, he mentioned that there is significant imbalance between financing delivery and prevention cares. I think it is really impressive that most of the focus is always on the delivery of medicine, while when patients are not sick, the preventive measures are minimal, ie. at dieting and eating habits.

Everyone has a different organizational style in compartmentalizing a closet. The differences in organizational methods come from a variety of roots, including personal preference, storage resources, materials stored, and usage. One of the main features of organization comes from the structure of the closet, depending on the doors/frame through which one may access materials, to the racks which hangers could be arranged. Since the structural component of the closet is difference for every closet, the organization of the closet is different for everyone.

Today we talked in detail about the ED. Dr. Ackerman mentioned that the ED is not necessarily a linear process. While this non-linearity is expected, as with most systems when human factors are involved, however, modeling and realizing nonlinear systems creates a certain level of difficulty. Therefore, this comparison presents a different perspective that indicates that the problems dealt with in the ED has a much higher level of complexity than I originally expected.

Communication plays an important role in ED. Not only does it allow nurses and doctors to work efficiently and keep patients aware of their situation, it can also provide (or inhibit) a certain psychological effect in calming down patients and family members by keeping them in the loop with the whirlwind of events that occur. This perception of viewing healthcare as a flow of communicative information is an interest notion for me.

Noise levels in hospitals are higher than WHO levels. At a maximum of 113 dB, the impulse noises are instrumental in disturbing patients' rest and recovery. I think the noise levels are pretty much expected, especially in an ER setting. This topic is really interesting in that that while white noise can be easily tuned out by those who stay in an environment for a short period of time, the impulses (such as alarms or dropped equipment) are meant to stand out. And so how does one contain these sounds that are disturbing for recuperating patients for extend the "alarm" to those who need to attend to the situation?

Heard a lot about the morning visit to Grady. Comparisons to class discussion to my own visit: I didn't think it was as noisy as everyone made it out to be. I feel the general white noise is easily established within minutes of walking in. The PA system is however, difficult to ignore. I had a hard time hear Ellie, our tour guide in the ambulatory waiting room when that happened. I also got past the metal detector by coming in in the main entrance of the hospital, instead of the ER entrance. Security issue? I think so. I did like how streamline the registration desks were. And patients seemed decently pleasant while waiting... No angry outbursts, at least.

Pecha Kucha day: It was interesting seeing how everyone else interpreted the ER. While it was my first time visiting the ER, I'm glad I wasn't the only one who had semi-positive perspectives about the ER. After all, it should be a somewhat stressful environment. If I were a patient and the medics were lackadaisical, I would be more stressed about my situation.

I really enjoyed hearing about Frank's perspective on Grady's ER. He mentioned about lacking privacy at check-in at the waiting room. I noticed this also, but didn't give it much thought. When I walked past registration during my visit, I heard exactly what was wrong with the patient checking in, even though I was a few feet away and the patient was turned away from me. It is interesting that while the ambient noise can be tuned out, patients still have to talk louder than usual to be heard. And it is difficult to do so while keeping medical information private.
