17. An oscillating positive expiratory pressure system comprising:
an oscillating positive expiratory pressure device;
an adapter comprising:
a body having a first end removably coupled to the oscillating positive expiratory pressure device, a second end opposite the first end, a tube defining a flow channel defined between the first and second ends, and a single port communicating with the flow channel between the first and second ends;
a flexible membrane disposed across the port and comprising a first side in fluid communication with the flow channel and a second, opposite side;
a first chamber defined on the second side of the membrane;
a single pressure sensor or microthermal flow sensor in flow communication with the first chamber by way of the single port;
a second chamber defined on the first side of the membrane, wherein the body comprises a curved wall extending into the flow channel and defining at least in part the second chamber, wherein the curved wall has a concave side defining at least in part the second chamber and a convex side defining at least in part the flow channel; and
a damping orifice formed in a curved portion of the curved wall between the convex and concave sides and communicating between the flow channel and second chamber, wherein the damping orifice opens transverse to a flow through the flow channel; and
a control module coupled to the adapter and operative to collect data from the single pressure sensor or microthermal flow sensor.
