Multipurpose therapeutic face mask

A method of preparing a therapeutic face mask configured for oxygen administration for administration of inhaled medication to a patient while the face-engaging portion is engaged with the patient's face, comprising the steps of:

• removing from the therapeutic face mask an oxygen reservoir bag that is detachably secured to the therapeutic face mask in fluid communication with a face-engaging portion of the therapeutic face mask, while the face-engaging portion remains engaged with the patient's face and a filter associated with the therapeutic face mask filters air exhaled by the patient;
• and
• detachably securing a nebulizer to the therapeutic face mask in place of the oxygen reservoir bag so that the nebulizer is in fluid communication with the face-engaging portion of the therapeutic face mask while the face-engaging portion remains engaged with the patient's face and the filter associated with the therapeutic face mask filters air exhaled by the patient.

The connector of claim 22, wherein each anti-asphyxia valve assembly comprises a single anti-asphyxia valve disposed in the corresponding exhalation port and oriented to:

• permit fluid flow from the connector to ambient through the exhalation port during exhalation;
• and
• permit fluid flow from ambient to the connector through the exhalation port during inhalation only when fluid flow to the treatment-receiving end of the connector is less than inspiratory effort during inhalation.

An oxygen therapy face mask, comprising:

• a face-engaging portion having an inlet passage through which oxygen from a pressurized source can be received;
• a valve assembly connected to the inlet passage having a first one-way valve operable to permit flow of oxygen from a source thereof to a patient and inhibit flow in the opposite direction, the valve assembly also having an inlet/outlet passage with a two-way valve permitting ambient air to flow to the patient and permitting exhaled air to flow from the patient to the ambient atmosphere.
