The apparatus of claim 5, wherein substantially no aerosol travels into the endotracheal tube portion of the Y connector when there is no inspiratory flow though the inlet portion. 7. A system for providing nebulized fluid to a patient receiving air from a ventilator, comprising: a breathing circuit comprising a Y connector, the Y connector comprising an inlet portion, an endotracheal tube portion and an outlet portion; a nebulizer positioned to provide nebulized fluid into the inlet portion of the Y connector, the nebulizer comprising: a vibratory aerosolization element having a first face, a second face and a plurality of apertures therethrough; wherein the vibratory element may be caused to vibrate at least in part by an electrical signal in a manner so as to draw fluid into the apertures at the first face thereof and emit the fluid as a low velocity nebulized cloud from the second face, and wherein the force of the emitted cloud is small enough that substantially all of the cloud may travel no further than the inlet portion of the Y connector when there is no inspiratory flow through the inlet portion. 8. A method of providing nebulized fluid to a patient receiving air from a ventilator, comprising: providing a ventilator, providing a breathing circuit to connect the ventilator to a patient, the breathing circuit comprising a Y connector, the Y connector comprising an inlet portion, an endotracheal portion and an outlet portion, providing a nebulizer positioned to provide aerosol into the inlet portion of the Y connector, the nebulizer comprising a vibratory aerosolization element, the vibratory aerosolization element operable in part by an electronic signal; providing an electronic signal that causes the aerosolization element to vibrate in such a manner as to deliver a cloud of mist into the inlet portion of the inlet portion during an interval in which there is substantially no inhalation flow through the inlet portion, such that the cloud remains substantially within the inlet portion; providing an inhalation flow from the ventilator in such a manner as to sweep substantially the entire cloud of mist through the endotracheal tube portion to the patient substantially upon the commencement of the inhalation flow. 9. A method of providing nebulized fluid to a neonatal patient receiving air from a ventilator, comprising: providing a ventilator, providing a breathing circuit to connect the ventilator to a patient, the breathing circuit comprising a Y connector, the Y connector comprising an inlet portion, an endotracheal portion and an outlet portion, providing a nebulizer positioned to provide aerosol into the inlet portion of the Y connector, the nebulizer comprising a vibratory aerosolization element, the vibratory aerosolization element operable in part by an electronic signal; providing an electronic signal that causes the aerosolization element to vibrate in such a manner as to deliver a cloud of mist into the inlet portion of the inlet portion during an interval in which there is substantially no inhalation flow through the inlet portion, such that the cloud remains substantially within the inlet portion; providing an inhalation flow from the ventilator in such a manner as to sweep substantially the entire cloud of mist through the endotracheal tube portion to the patient substantially upon the commencement of the inhalation flow. 10. A system for providing aerosol into a ventilator circuit, comprising; a ventilator capable of providing at least one cycle of inhalation air; a ventilator circuit comprising an inhalation tube, and exhalation tube and an intubation tube, and a Y connector therebetween; a sensor configured to monitor a point within an inhalation cycle of the ventilator; a nebulizer comprising a microprocessor, the microprocessor configured to calculate an inhalation profile based on the sensed point of operation of the ventilator, the microprocessor further configured to follow at least one algorithm for operating the nebulizer based on an inhalation profile, wherein the algorithm is configured to provide a point for the commencement of aerosolization and a point for the cessation of aerosolization. 11. The system of claim 10, wherein the of aerosolization and the point for cessation of aerosolization are not designed to coincide with the commencement of an inhalation phase and the cessation of an inhalation phase of an inhalation cycle provided by the nebulizer. 12. The system of claim 10, wherein the point for commencement of aerosolization and the point for cessation of aerosolization are not designed to coincide with the commencement of an exhalation phase and the cessation of an exhalation phase of an inhalation cycle provided by the nebulizer. 13.
