Abstract:	For the large population of massive stars lying behind dust, among which are the youngests and potentially the most massive of our Galaxy, none of the commonly used wind diagnostics can be applied. As an alternative, a few observable infrared hydrogen lines are strong enough to hold wind diagnostics similarly to Hα. Using current state-of-the-art model atmospheres adapted to near-infrared studies, we investigate the profiles, line forming region and formation mechanisms for three of them as a function of dM/dt.
