Demand for sleep apnea aids rises
ResMed makes devices that treat sleep apnea, a condition in which breathing becomes restricted, affecting sleep quality.

The world’s second-biggest maker of machines for breathing-related sleep disorders posted record profit in the second quarter. ResMed Inc., based in California, said sales from US flow generators rose 4 percent, reversing the 2 percent decline posted in previous quarter, as a new line of devices spurred demand for products that help sleep apnea sufferers breathe. Net income rose 8 percent to $62.9 million in the quarter.
