Systems and methods for delivering an agent to a user's lungs and for simultaneously monitoring lung health

A system for delivering an agent to be taken up by a user's lungs and for simultaneously monitoring said user's lung health, comprising:

• an inhalant-flow detection system, comprising:
• a tube having a first end to receive air intake and a second end having a shape and size suitable to be used as a mouth piece for a user to receive inhalant therethrough, said first end being one of attached to or configured to be attachable to an agent delivery device, wherein said agent delivery device is configured to supply a quantified dose of said agent into air flowing through said tube to provide said inhalant, and
• a flow sensor arranged to intercept a portion of inhalant flowing through said tube and to provide detection signals regarding inhalant speed as a function of time;
• and
• a computer-executable medium comprising non-transient computer code, which when executed on a computer, causes the computer to:
• receive said detection signals from said flow sensor for an inhalation time period of said agent,
• receive information about a quantity and type of agent provided by said agent delivery device for said inhalant during said inhalation time period,
• calculate a delivered dose of said agent to be taken up by said user's lungs based on at least said detection signals received, said information received about said quantity and type of agent, and information concerning physiology of said user, and
• provide an output signal based on said delivered dose calculated,
• wherein said inhalant-flow detection system is configured to provide substantially non-turbulent, unobstructed air flow from said first end to said second end of said tube.
