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. ## Claims ### Claim 1 A ventilator system, comprising: 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 gas flow restrictor that is different from a gas flow restrictor of the other ventilator masks of the at least two ventilator masks; and a ventilator supply system, comprising: an air/oxygen source; a connector configured to couple with each of the at least two ventilator masks; an air/oxygen supply system comprising a detection system capable of determining a pressure created by the application of air/oxygen to a mask coupled to the ventilator supply system; a proportional valve coupled to the detection system and the air/oxygen source, wherein the proportional valve controls the flow rate of air/oxygen from the air/oxygen source to the detection system; and a controller coupled to the detection system, wherein the controller determines, during use, which mask, among the two or more ventilator masks, is coupled to the air/oxygen supply system based on the pressure detected by the detection system. ### Claim 2 (depends on 1) The ventilator system of claim 1, wherein the gas flow restrictor comprises a variation in an internal diameter of the flow restrictor, from one ventilator mask to another, such that the back pressure caused by the air/oxygen flow to each of the ventilator masks is different. ### Claim 3 (depends on 1) The ventilator system of claim 1, wherein the controller is further configured to set, based on the size of the ventilator mask determined to be coupled to the air/oxygen supply system, a pre-selected maximum pressure limit, a pre-selected breath volume, or a pre-selected respiratory-rate to provide air/oxygen to the ventilator mask as a function of the size of the ventilator mask coupled to the air/oxygen supply system. ### Claim 4 (depends on 1) The ventilator system of claim 1, wherein the controller is further configured to provide air/oxygen to the ventilator mask at the pre-selected maximum pressure limit, the pre-selected breath volume, or the pre-selected respiratory-rate. ### Claim 5 (depends on 1) The ventilator system of claim 1, further comprising a mask conduit configured to couple the ventilator supply to the ventilator mask. ### Claim 6 (depends on 1) The ventilator system of claim 1, further comprising a pressure switch coupled to the air/oxygen source, the proportional valve, and the controller, wherein the controller initiates the delivery of air/oxygen to the detection system by operating the proportional valve, in response to a predetermined pressure detected by the pressure switch. ### Claim 7 (depends on 1) The ventilator system of claim 1, wherein the selected range of sizes comprises one of an infant-size range, a child-size range, and an adult-size range. ### Claim 8 (depends on 1) The ventilator system of claim 1, further comprising a signaling device, coupled to the controller, configured to transmit a signal indicating that the air/oxygen supply system is in need of service. ### Claim 9 (depends on 1) The ventilator system of claim 1, further comprising a signaling device, coupled to the controller, configured to transmit a signal corresponding to a measure of one or more observed air/oxygen flow parameters. ### Claim 10 (depends on 1) The ventilator system of claim 1, further comprising a signaling device, coupled to the controller, configured to transmit a signal indicating a condition of at least one of: blockage, proper flow, and/or leakage of air/oxygen. ### Claim 11 (depends on 1) The ventilator system of claim 1, further comprising a communication device configured to enable communication with one or more emergency response personnel. ### Claim 12 (depends on 1) The ventilator system of claim 1, further comprising a signaling mechanism configured to deliver one or more signals to a rescuer relating to timing of chest compressions of the person, wherein the timing of the chest compressions for at least one of the signals is based at least in part on a time of delivery of at least one of the artificial respirations. ### Claim 13 (depends on 12) The ventilator system of claim 12, wherein the signaling mechanism is further configured to deliver a signal to the controller, when chest compressions are detected, wherein, when chest compressions are detected the delivery of air/oxygen to the mask is discontinued.
