Precise Wavelength Used to Gently Image Lungs of Newborns
To avoid the harmful radiation resulting from x-rays, near-infrared (NIR) spectroscopy has been used to image oxygen concentrations in the lungs of newborns, a technique that could be used to noninvasively monitor premature babies with underdeveloped lungs and increase survival rates. Emilie Krite Svanberg, an anesthesiologist and researcher at Lund University, reported a spectroscopic method using precisely 760.445-nm light. Both continuous-wave and time-resolved techniques were applied; both were able to determine changes in tissue oxygenation, though the time-resolved technique reported more realistic values with smaller interindividual differences.
