The present disclosure pertains to an infant sleeping surface attachment system configured to facilitate vital signs monitoring of, and/or delivering oxygen to, an infant laying on an infant sleeping surface. The system is configured to engage a vital signs monitoring device so the vital signs monitoring device has a view of the infant sleeping surface. The system has a retracted position and a closed position. The closable cavity has a mounting apparatus for engaging a vital signs monitoring device inside the cavity. The mounting apparatus is configured such that the vital signs monitoring device maintains a field of view on a region of interest and minimizes the possibility of occluding the view of the vital signs monitoring device. Thus, it is possible to continuously monitor of the infant from inside the cavity without having any glass/plastic material (e.g., the wall of a typical oxyhood) obstructing the field of view.
