I was stabbed 7 times. I went under hemothorax surgery. I had tubes going out my mouth, tubes out my side. it's been 9 days today since this happened. I was released 4 days ago. I'm very blessed to be alive. Great explanation. thanks for taking the time to explain what somewhat happened to me. I know their are others. I lost half my blood. I'm one of the survivors. may God help you to help others....ty for letting me share.
nice video.i've been looking for such a video that can help me to understand the basics of chest drainage system and i finally got it.thank u so much for making this concept so clear and easy to understand
I was following your video until 16:35 when you state that there is actually water behind the front panel in the suction control chamber. However, this is a DRY suction set up-- meaning there is not water in the suction control chamber, correct? Isn't that the main difference between a WET and a DRY suction chest tube drainage system set up (whether or not there is water in the suction control chamber)?
"Negative" pressure is a commonly-used but confusing idea. "Negative (air) pressure" means "SUBATMOSPHERIC" pressure, i.e. "the air pressure in area X is LOWER than atmospheric pressure'. "Positive" pressure means 'the air pressure in area X is higher than atmospheric pressure'. It can be a bit hard to visualize. 'Positive' pressure commonly exists where a fluid/gas/liquid is being compressed or squeezed (its container is exerting forces in the direction that tries to make the gas volume smaller), whereas negative pressure exists where the container is trying to pull outward on the gas, i.e. the container is trying to pull the gas into taking up a larger volume than its resting volume.
This video is pretty good, but uses imprecise terminology and almost circular reasoning in some places. For example: "Systems flow from high to low pressure." What do you mean by "a system flows"? It's a fluid (gas or liquid) that flows, not a 'system'. But overall well done.
