Kerley’s A lines (arrows) are linear opacities extending from the periphery to the hila; they are caused by distention of anastomotic channels between peripheral and central lymphatics. Kerley’s B lines (white arrowheads) are short horizontal lines situated perpendicularly to the pleural surface at the lung base; they represent edema of the interlobular septa. Kerley’s C lines (black arrowheads) are reticular opacities at the lung base, representing Kerley’s B lines en face.
These radiologic signs and physical findings suggest cardiogenic pulmonary edema.
克羅克夫聲(Korotkoff sounds) 總共可以分成5 phase,一開始的聲音較大聲也較為響亮,隨著壓力的減弱,聲音的質地也有所改變,變得比較減弱且不清楚(muted and muffled)
The first Korotkoff sound is the snapping sound first heard at the systolic pressure. Clear tapping, repetitive sounds for at least two consecutive beats is considered the systolic pressure.
The second sounds are the murmurs heard for most of the area between the systolic and diastolic pressures.
The third = A loud, crisp tapping sound.
The fourth sound, at pressures within 10 mmHg above the diastolic blood pressure, were described as "thumping" and "muting".
The fifth Korotkoff sound is silence as the cuff pressure drops below the diastolic blood pressure. The disappearance of sound is considered diastolic blood pressure -- two mm Hg above the last sound heard.
The second and third Korotkoff sounds have no known clinical significance.
As the new year coming, we get into a exam hell. The first thing I wish is all past. If I want to have a good Chinese new year at home, getting a good grade is essential. The second I wish I can keep attention on study and pay more time on it. The lastest, I want to have more exercise. In the past year, I’m to lazy to do that, to do a couch potato is not good to my health. To wish is easy, but it’s hard to achieve. The best wish for me maybe is wishing I can really do that.
Early birds or late owls?
There are many kinds of people in this world. Someone like to get up early and the other doesn’t. If you are always get up early to do start the daily life, you are the early birds. One the other hand, always getting up and sleeping late, we call that’s kind of men as late owls. Both of them have advantages and disadvantages, it depends on how you see these two types of lifestyle to decide which one is better. For me, I prefer to get up late and work until late at night. It’s a very nice thing to sleep late and lie on the bed. To sleep well is the most important thing for people. That’s help you work with energy. Because I get up late, I often work until night. If I don’t feel tired, sometimes I still be awake at am. 3 o’clock. That’s not a good habit, whatever style need to keep a regular life. No matter what you choice, you are the early birds or late owls type of person, the most important thing is that, you must find the best suitable way for yourself.
