Monitoring

Everyone responds to general anesthetics differently, which can make administering the correct dose tricky. A new device is designed to help, by continuously monitoring anesthetic levels in patients' bloodstreams during surgical procedures.

Even though at-home use of an inhaler or insulin pen can be extremely important, doctors have to pretty much just hope that patients are doing it right. A new system, however, could objectively assess patients' technique within their homes.

Nobody likes needles – at best they’re an unpleasant means to an important end. Microneedle patches could be a painless alternative, and now researchers have developed a way to use them to detect biomarkers at much lower levels without drawing blood.

With colony collapse disorder continuing to decimate honeybee populations, it's more important than ever for beekeepers to monitor hive conditions. The ApisProtect system is made to automate the process, potentially catching problems earlier.

While we have already heard about contact lenses that monitor medical conditions, such lenses are often made from non-traditional materials. A new one, however, is composed of the same hydrogel as regular store-bought contacts.

In order to see if an antidepressant works, patients have to take the drug for at least a month. New research, however, suggests that by monitoring a sleeping patient's brainwaves, the effectiveness of an antidepressant can be gauged in a week.

Many readers are likely already familiar with the oximeters that measure blood oxygen levels via the patient's finger. Well, scientists have now developed a device that works on the same principle, but it can be non-invasively used on unborn fetuses.

Helicopters regularly have to get their rotor blades inspected, so they can be replaced if they're wearing out. Using the BladeSense system, however, the aircraft would be able to monitor the condition of their blades in real time, while in flight.

In order to gauge the risk of mosquito-borne diseases, authorities typically monitor the numbers of specific mosquito types that are known to carry those illnesses. A new system makes it possible to do so remotely, and thus more effectively.

Brain-implanted electrodes have numerous uses, ranging from the controlling of prosthetic arms to the monitoring of neural activity. They could soon be more effective than ever, as scientists have now developed ones that are soft and squishy.

If someone is suffering from a chronic wound, it's important for their doctor to continuously know the status of that injury. A new bandage is designed to keep physicians in the loop, via everyone's favorite wonder material – graphene.

There is a large disparity between the survival rates of prematurely born babies in the developing world and those in the developed world, but scientists at Northwestern University have developed of new kind of wireless sensor to help bridge the gap.
