3D printed airway splints restore breathing

At the University of Michigan, three children under 2 with tracheobronchomalacia had 3D printed devices implanted to open their airways and restore their breathing. Professors Glenn Green and Scott Hollister were able to create and implant customized tracheal splints for each patient. The device was created directly from CT scans of their tracheas, integrating an image-based […]

Built-in, contactless sensors monitor breathing

Novelda’s building-integrated “XeThru” sensor modules detect human presence and monitor respiration.  Breath rate and depth are measured and tracked in real-time.   The use of radio waves, rather than infrared, ultrasound or light, allows the modules to ‘see through’ a variety of objects, including  building materials and blankets. The sensors are intended for hidden, tamper proof, […]

Sensor seatbelt detects fatigue

HARKEN is a sensor embedded  driver’s seatbelt and seat cover that monitors cardiac and respiratory rhythms.  Its hidden signal processing unit analyzes the data in real time.  The prototype is being developed at Spain’s  Biomechanics Institute in Valencia. When the sensor data indicates the person is falling asleep, an alarm will wake the driver.  Closed track testing […]

Phone pulse oximeter detects preeclampsia, pneumonia

Christian Petersen and colleagues at the University of British Columbia have developed a low cost smartphone pulse oximeter.  Its light sensor attaches to a user’s fingertip to measure blood oxygen levels. Software analyzes and simply displays the data on a phone, tablet or computer. The phone oximeter can measure heart and respiration rates, and be used […]

Stem cells converted to functional lung cells; could impact modeling, drug screening, transplantation

http://www.nature.com/nbt/journal/vaop/ncurrent/full/nbt.2754.html Columbia professor Hans-Willem Snoeck and colleagues have transformed human stem cells into functional lung and airway cells.  This has significant potential for modeling lung disease, screening drugs, studying human lung development, and, ultimately, generating lung tissue for transplantation. The research builds on Dr. Snoeck’s 2011 discovery of a set of chemical factors that can turn human embryonic […]

Crowdfunded “smart sock” monitors baby’s breathing

http://www.owletcare.com Owlet Baby Monitors has created a baby “smart sock” with sensors that transmit a child’s heart rate, oxygen levels, skin temperature, sleep quality, and sleep position (rollover alerts) to a parent’s smartphone.  The company has launched a crowdfunding campaign as it goes through the FDA approval process.

Machine learning in the ICU

http://www.technologyreview.com/news/515461/machine-learning-and-risk-prediction-in-the-icu/ Etiometry is building a clinical-decision support system to interpret large volumes of real-time patient data and guide diagnosis and treatment.  It integrates and analyzes information from heart monitors, ventilators, and pressure sensors and plugs the data into predictive models that have been built on prior patient outcomes.

Fiber optic device for lung disease detection

http://www.cir.ed.ac.uk/news/multidisciplinary-optical-imaging-team-awarded-£115m Researchers at the University of Edinburgh, Heriot-Watt University and the University of Bath have developed a fiber-optic device to detect potentially fatal lung conditions in intensive care patients.   Its sensors will also continuously monitor blood in critically ill adults and babies with out the need for blood sampling. The microscopic probe will detect and monitor […]
