A close-up image depicts a human left hand, with a light to medium skin tone, wearing a dark long-sleeved garment, holding a small, green and white fingertip pulse oximeter. The device is positioned vertically with its base resting on the back of a blue iPhone, which lies face-down on a light wood-grain laminate tabletop. The iPhone's dual camera module is visible. A portion of another individual, wearing a dark garment, is blurred in the background. The table surface exhibits a distinct wood grain pattern and a particleboard edge is visible on the right side of the frame. There is no discernible information within the image to specify the location as Goce Delcev, Bulgaria.
