Abstract
Provided is a method that includes automatically providing air/oxygen at a pre-selected maximum pressure limit, breath volume and respiratory-rate. The pre-selected maximum pressure limit, breath volume, and respiratory-rate are automatically set as a function of a size of a mask coupled to an air/oxygen supply system. Further provided is a ventilator system that includes a ventilator mask, a ventilator supply system, and a mask conduit. The ventilator mask is configured in a size that will fit upon a selected range of sizes of human faces. The ventilator supply system includes an air/oxygen source and an air/oxygen regulator system configured to regulate air/oxygen flow parameters as a function of the size of the mask. The mask conduit is configured to couple the ventilator supply to the ventilator mask.

A method, comprising:
- selecting a mask from a set of two or more ventilator masks, wherein each of at least two of the ventilator masks is configured in a size that will fit upon a different range of sizes of human faces than at least one other ventilator mask in the set of two or more ventilator masks, wherein each of the at least two ventilator masks comprises a mechanical keying feature that is different from a mechanical keying feature of the other ventilator masks of the at least two ventilator masks;
- coupling the selected ventilator mask to an air/oxygen supply system, wherein the an air/oxygen supply system comprises mechanical keying features that are complementary to the keying features of the ventilator masks, wherein one switch among a plurality of switches on the air/oxygen supply system is switched from one state to another when the selected ventilator mask and the air/oxygen supply system are coupled;
- automatically determining the size of the ventilator mask coupled to the air/oxygen supply system based on the mechanical keying feature of the selected ventilator mask;
- automatically setting, based on the size of the ventilator mask determined to be coupled to the air/oxygen supply system based on the mechanical keying feature, a pre-selected maximum pressure limit, a pre-selected breath volume, or a pre-selected respiratory-rate to provide air/oxygen to the selected ventilator mask as a function of the size of the ventilator mask coupled to the air/oxygen supply system, wherein the setting of the pre-selected maximum pressure limit, the pre-selected breath volume, or the pre-selected respiratory-rate to provide air/oxygen is based on which one of the plurality of switches is switched when the selected ventilator mask and the air/oxygen supply system are coupled, wherein which one of the plurality of switches is switched is based on the mechanical keying feature of the selected ventilator mask;
- and
- automatically providing air/oxygen to the selected ventilator mask at the pre-selected maximum pressure limit, the pre-selected breath volume, or the pre-selected respiratory-rate.
