摘要:
Described are methods and systems for delivering pharmaceutical gas to a patient. The methods and systems utilize a high flow valve and a low flow valve in parallel flow paths. The pharmaceutical gas may be provided as a pulse during the first half of the patient's inspiratory cycle.
摘要:
A gas delivery system including a gas delivery device (100), a control module (200) and a gas delivery mechanism is described. An exemplary gas delivery device includes a valve (107) assembly with a valve and circuit including a memory (134), a processor (122) and a transceiver (120) in communication with the memory. The memory may include gas data such as gas identification, gas expiration and gas concentration. The transceiver on the circuit of the valve assembly may send wireless optical line-of-sight signals to communicate the gas data to a control module. Exemplary gas delivery mechanisms include a ventilator (400) and a breathing circuit (410). Methods of administering gas are also described.

摘要:
Methods and systems for delivering a total quantity of pharmaceutical gas to a patient. The methods and systems provide one of a low amount and high amount of pharmaceutical gas to a patient. The selection of the high amount or low amount may be determined by comparing the amount per unit of time of pharmaceutical gas delivered to the patient over the past number of breaths to the required quantity of pharmaceutical gas per unit of time. Upon completion of delivering the total quantity of pharmaceutical gas to the patient, the system can terminate, continue, activate and alarm, etc.

摘要:
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.
