Inhalation system

A system comprising:

• means for starting a flow of an inhalant through a manifold;
• means for determining an inhalant concentration of the inhalant in the manifold;
• and
• means for stopping the flow of the inhalant through the manifold when the inhalant concentration is in a first specified inhalant-concentration range.

A method comprising:

• determining an inhalant concentration in a manifold;
• calculating at least one of a retrospective and a prospective inhaled dose in response to the inhalant concentration;
• and
• starting and stopping a flow through the manifold until the at least one of the retrospective and the prospective inhaled dose is greater than or equal to a specified dose.

A system comprising:

• means for determining an inhalant concentration in a manifold;
• means for calculating at least one of a retrospective and a prospective inhaled dose in response to the inhalant concentration;
• and
• means for starting and stopping a flow through the manifold until the at least one of the retrospective and the prospective inhaled dose is greater than or equal to a specified dose.

A system comprising:

• at least one manifold;
• an inhalant dissemination device coupled to the at least one manifold;
• an inhalant characterization device coupled to the at least one manifold;
• and
• a control module operably coupled to the inhalant dissemination device and the inhalant characterization device, said control module configured to
• determine an inhalant concentration in a manifold, and
• calculate at least one of a retrospective and a prospective inhaled dose in response to the inhalant concentration, and
• start and stop a flow through the manifold until the at least one of the retrospective and the prospective inhaled dose is greater than or equal to a specified dose.
