Claim 26:
27. The method of claim 23, wherein the airflow switching valve further comprises a spring positioned between the outer housing and the inner housing, the spring being compressed in a breath state and extended in a non-breath state, the breath state being when the airflow switching valve receives the first inspiratory breath or the second inspiratory breath, the non-breath state being when the airflow switching valve is not receiving the first inspiratory breath or the second inspiratory breath,
wherein receiving the first inspiratory breath causes the inner housing to compress the spring and simultaneously rotate into the first position by way of the plurality of extensions translating within the track of the outer housing,
wherein, after providing the first inspiratory breath to the first patient, the spring is configured to extend and cause the inner housing to rotate into an intermediate position by way of the plurality of extensions translating within the track of the outer housing, the intermediate position being between the first position and the second position,
wherein receiving the second inspiratory breath causes the inner housing to compress the spring and simultaneously rotate into the second position by way of the plurality of extensions translating within the track of the outer housing, and
wherein, after providing the second inspiratory breath to the second patient, the spring is configured to extend and cause the inner housing to rotate into another intermediate position by way of the plurality of extensions translating within the track of the outer housing, the other intermediate position being between the second position and the first position,
wherein receiving the second inspiratory breath causes the inner housing to compress the spring and simultaneously rotate into the second position by way of the plurality of extensions translating within the track of the outer housing, and
wherein, after providing the second inspiratory breath to the second patient, the spring is configured to extend and cause the inner housing to rotate into another intermediate position by way of the plurality of extensions translating within the track of the outer housing, the other intermediate position being between the second position and the first position.
