Provide a kind of equipment of the nitric oxide level of intrapulmonary for control object. The equipment includes the detector for detecting the respiratory cycle of the object and the stimulator for applying acoustic stimulation or vibratory stimulation to the object. The stimulator is controlled according to the respiratory cycle detected. Particularly, acoustic stimulation can be provided at the beginning of air-breathing. In this way, nitric oxide production flow can be controlled, to ensure that the nitric oxide by nose is almost inhaled into. This provides higher nitric oxide concentration in lung/alveolar.
