It has been discovered that high amplitude, low frequency, broadband spectrum pressure oscillations of sufficient time duration can help stabilize lung volumes and improve gas exchange in a patient receiving ventilation assistance by helping to recruit and stabilize alveoli. A novel device is presented which can produce pressure oscillations having high amplitudes, a low broad-band frequency spectrum and long time duration. Additionally, the device can maintain a patient's mean airway pressure at one or more controlled levels. The device can control the oscillatory amplitude, frequency range and composition, time duration, and mean airway pressure levels by adjusting certain device parameters, such as the angle and depth of the device in a fluid. A device and mechanical system for remotely adjusting and measuring the angle of the device in a fluid are also disclosed. Furthermore, a device and system are disclosed that can deliver pressure oscillations having high amplitudes, a low broad-band frequency spectrum, long time duration, and multiple mean airway inspiratory and expiratory pressure levels. The device and system also provide means for controlling respiration timing in a patient, including: breaths per minute, inspiratory time, and the ratio of inspiratory to expiratory time.

The present invention has shown that not all salts of pyruvic acid enhance lung functions or enhance the synthesis of lung surfactants and that certain salts of pyruvic acid with the correct concentrations of calcium, phosphate and magnesium, is are synergistic in their ability to enhance the synthesis of lung surfactants that will enhance lung alveoli functions, while decreasing coughing and lung tightness, and increasing oxygen saturation values to prevent hypoxemia. This patent demonstrates that the sodium pyruvate formula with calcium, phosphate and magnesium was superior over standard sodium pyruvate formula in saline alone in the removal of mucus, reduction of lung or sinus infections, and in reducing drug side effects and congestion.

The invention discloses a planting method for increasing peanut yield. The planting method comprises the step of seeding, wherein two seeds are vertically planted in a seeding ditch in parallel, embryonic roots are downward, the butt seam of two cotyledons is parallel to a ridge, and two holes of peanut are seeded on the ridge in a staggered manner. According to the invention, by changing the seeding method of seeds, two cotyledons are parallel to the ridge after peanut seedling emergence, so that first pair of lateral branches grown from the cotyledon node are both vertical to the ridge, and are trim and consistent; and at the same time, peanut is planted on the ridge in the staggered manner, thus the formed colony structure is favorable to increasing light transmittance and gas exchange in canopy, increasing photosynthetic efficiency of the canopy and further increasing legume yield. Tests prove that by adopting the method to plant peanut, the peanut seedling emergence is advanced by 1-2d as compared with routine seeding, the CO2 concentration and light transmittance at the roots of the plants on the ridge are increased by 2.2-7.6% and 9.6-12.3%, respectively, the photosynthesis intensity of the canopy is increased by 8.7-12.8%, and the legume yield is increased by 8.7-13.4%. Therefore, the planting method can obviously increase peanut yield.
