    What happened when I tried the U.S. Army’s tactic to fall asleep in two minutes

    The technique has been used to help people fall asleep in the most uncomfortable circumstances, and best of all, it’s said to work for 96% of the people who tried it for six weeks.

    Do you suffer from sleep apnea? Have you ever woken up to find your CPAP mask came off? Here’s an Arduino-powered solution to that problem.

    This monitor will let you know if your CPAP mask comes off at night

    Bin Sun has developed a CPAP monitor that measures air pressure via an MPXV7002DP sensor—often also used to determine the airspeed of RC models.

    The device is controlled by an Arduino Nano, and when it detects improper pressure readings in alarm mode, it activates a small buzzer, displaying a “check mask” message. It can also be set up to run in manometer mode in order to observe pressure changes.

    Wearable Patch Uses Machine Learning to Detect Sleep Apnea

    Getting screened for sleep apnea often means spending a night in a special clinic hooked up to sensors that measure your brain activity, eye movement, and blood oxygen levels. But for long-term, more convenient monitoring of sleep apnea, a team of researchers has developed a wearable device that tracks a user’s breathing.

    Sleep-deprived brains may be asleep and awake at the same time

    For something that can occupy such a significant chunk of time, sleep still remains a mysterious part of our lives. Although it is known to play a role in mental and physical health, such as metabolism and memory, there is much that is still not well understood.

    A Vital Hack Could Turn Medical Devices Into Ventilators

    Hundreds of thousands of lower-grade breathing devices are going unused because manufacturers say they can’t perform life-saving functions. But a new patch might change that.

    As infections from the ongoing COVID-19 pandemic continue to climb, hospitals around the world are struggling with a potentially fatal shortage of ventilators, the bedside machines that help patients breathe when they’re unable to do so on their own. Meanwhile, hundreds of thousands of lower-grade breathing devices known as continuous positive airway pressure machines sit idle in closets or warehouses because their manufacturers say they can’t perform the same life-saving functions.

    Security researcher Trammell Hudson analyzed the AirSense 10—the world’s most widely used CPAP—and made a startling discovery. Although its manufacturer says the AirSense 10 would require “significant rework to function as a ventilator,” many ventilator functions were already built into the device firmware.
