摘要：
It has been discovered that high amplitude, low frequency, broadband spectrumpressure oscillations ofsufficient time duration can help stabilize lung volumes and improve gasexchange in a patient receivingventilation assistance by helping to recruit and stabilize alveoli. A noveldevice is presented which canproduce pressure oscillations having high amplitudes, a low broad-bandfrequency spectrum and longtime duration. Additionally, the device can maintain a patient's mean airwaypressure at one or morecontrolled levels. The device can control the oscillatory amplitude, frequencyrange and composition,time duration, and mean airway pressure levels by adjusting certain deviceparameters, such as the angleand depth of the device in a fluid. A device and mechanical system forremotely adjusting and measuringthe angle of the device in a fluid are also disclosed. Furthermore, a deviceand system are disclosed thatcan deliver pressure oscillations having high amplitudes, a low broad-bandfrequency spectrum, long timeduration, and multiple mean airway inspiratory and expiratory pressure levels.The device and systemalso provide means for controlling respiration timing in a patient, including:breaths per minute,inspiratory time, and the ratio of inspiratory to expiratory time.
