Abstract
Methods and systems for delivering a pharmaceutical gas to a patient. The methods and systems provide a known desired quantity of the pharmaceutical gas to the patient independent of the respiratory pattern of the patient over a plurality of breaths every nth breath, where n is greater than or equal to 1. The pharmaceutical gases include CO and NO, both of which are provided as a concentration in a carrier gas. The gas control system determines the delivery of the pharmaceutical gas to the patient to result in the known desired quantity (e.g. in molecules, milligrams or other quantified units) of the pharmaceutical gas being delivered. Upon completion of that known desired quantity of pharmaceutical gas over a plurality of breaths, the system can either terminate, continue, activate and alarm, etc.
