1. An apparatus for monitoring asthmatic conditions, wherein said apparatus is arranged for mounting to a spacer, said spacer having an input end, an output end and a mask mounted at said output end, and wherein an application of said mask to a face of a patient creates a cavity, said apparatus comprising:

  • an enclosure;

    a conduit for pneumatically coupling said enclosure to said cavity such that pressure changes in said cavity result in pressure changes in said enclosure;

    a pressure transducer mounted in fluid communication with said cavity for;

    sensing said pressure changes in said cavity; and

    producing an electrical output signal representative of said pressure changes;

    an analog to digital converter for converting said electrical output signal representative of said pressure changes to a digital value representative of said pressure changes;

    a memory; and

    a processor communicatively connected to said analog to digital converter and said memory for;

    receiving said digital value representative of said pressure changes; and

    transmitting, to said memory, said digital value representative of said pressure changes.
