A mammography apparatus includes a detector that detects X-rays transmitted through a breast, and an optically transparent or semitransparent pressing panel for pressing the breast. For example, the first cord is substantially circular in cross section and has a large diameter, the second cord is also substantially circular in cross section and has a small diameter, and the second cord can be removably housed in the first cord. A positive pressure is provided to the respiratory orifice via the first conduit and a second conduit having a third end and a fourth end, the fourth end connected to the respiratory delivery arrangement.
