What Is Obesity Hypoventilation Syndrome? Obesity hypoventilation (HI-po-ven-tih-LA-shun) syndrome (OHS) is a breathing disorder that affects some obese people. In OHS, poor breathing results in too much carbon dioxide (hypoventilation) and too little oxygen in the blood (hypoxemia). OHS sometimes is called Pickwickian syndrome.
Click on photo for a larger picture. In the photo above, I am holding two small vials of liquid metal. The vial on the right contains gallium, an element that melts at 29.76Â° Celsius (85.57Â° Fahrenheit). The vial on the left is an alloy that contains gallium, indium, and tin, and melts at -20Â° Celsius (-4Â° Fahrenheit). The gallium is liquid because I had the bottle in my shirt pocket, next to my warm body.
Lucky for us we have science and we have gallium. You donât have to be a scientist to appreciate this super metal. Gallium is a brittle, soft element that becomes a liquid at around 85Â°F, meaning itâll melt in your hands. When you freeze it, it possesses the rare trait of expanding, just like water. The most important feature of gallium is that itâs non-toxic, meaning thereâs no harm to your brain, heart and immune system!
