A CPR face mask has a substantially toroidal face engaging part positionable on the face of a patient to surround at least the mouth of the patient. A flexible generally conical part having a lower end extending around and is secured to an upper surface of the face engaging part, and an upper end with an aperture through which a CPR giving person can blow air which passes downwardly through the conical part and the toroidal part into the patient's mouth. The flexible generally conical part has a relatively short outwardly extending substantially horizontal portion at the lower end extending around and secured to the upper surface of the face engaging part, a relatively short portion extending upwardly and outwardly from an inner edge of the substantially horizontal portion, a relatively high frusto-conical portion extending upwardly and inwardly from an upper edge of the upwardly and outwardly inclined portion, a relatively short portion extending inwardly and downwardly from an upper edge of the frusto-conical portion and a central cylindrical portion extending upwardly from an inner edge of the inwardly and downwardly extending portion and providing said aperture. The mask can be positioned in a collapsed configuration for storage by downward movement of the central cylindrical portion to cause the frusto-conical portion to fold downwardly and extend into the toroidal face engaging part and can be returned to a ready-to-use configuration by an upward pull on the central cylindrical portion.
