People suffering from asthma or other chronic lung problems are typically only able to get a measure of their lung function at the doctor’s office a few times a year by blowing into a specialized piece of equipment. More frequent testing at home could detect problems earlier, potentially avoiding emergency room visits and hospitalization. Hand holding SpiroSmart SpiroSmart is a research app to let people test their lung function using only a smartphone.S. Patel, Univ. of Washington A new tool from researchers at the University of Washington, UW Medicine and Seattle Children’s hospital lets people monitor their lung function at home or on the go simply by blowing into their smartphones. A paper presented this month at the Association for Computing Machinery’s International Conference on Ubiquitous Computing showed results that came within 5 percent of commercial devices, meaning it already meets the medical community’s standards for accuracy. “There’s a big need in the pulmonar...

Sealable canisters, or cabinets, known as desiccators keep contents dry (and dust-free) with the help of desiccant. These economical storage containers are used for electronics, reagents, and other humidity-sensitive items. While there are at least four types of desiccators, the most typical are non-vacuum desiccators and vacuum desiccators. Usually, vacuum desiccators include a stopcock to enable internal air to evacuate, thus creating lower humidity levels. A separate vacuum pump may be necessary but some models include a built-in pump. From polypropylene to polycarbonate to glass and stainless steel, desiccators are crafted in various materials and available in a variety of sizes. For a more significant investment, you can choose a static-free desiccator for instruments that are sensitive to electrostatic discharges. Electronic desiccators automatically remove moisture from desiccant and regenerate it every five hours. Some also offer built-in thermohygrometers. Space-saving units t...

  Most dogs will chew nearly anything: bones, toys, shoes, socks, etc. But would you know what to do if something became lodged in the windpipe or stuck on the palate and your dog began to choke? It's important that you do not wait for veterinary assistance, as the dog may suffocate.   WHAT TO WATCH FOR   If the dog is suffocating, it will often panic. A dog may paw at its mouth if something is lodged, though this does not necessarily mean it is choking. Another suspicious sign of choking is an unresponsive or unconscious dog; in these cases, check the throat and mouth for foreign objects.   PRIMARY CAUSE   Almost any small object can cause choking, though the most common are hard rubber balls, lumps of gristle, and chew toys or sticks that have become swollen due to moisture.   IMMEDIATE CARE   Be very careful when dealing with a choking dog, as even calm animals will panic when they cannot breathe. Protect yourself by restraining the dog, but do not muzzle it.   Use both hands to...
