In one embodiment, the method includes sensing a sensed parameter associated with delivery of the breathing gas, changing a control parameter associated with a flow/pressure control element in response to a difference between the sensed parameter and a first predetermined sensed parameter value during a first portion of a breathing cycle, determining a transition from the first portion to a second portion of the breathing cycle based at least in part on the changing control parameter, changing the control parameter to cause a first change in the sensed parameter during the second portion of the breathing cycle based at least in part on the determined transition, and changing the control parameter to cause a second change in the sensed parameter during a third portion of the breathing cycle based at least in part on the first predetermined sensed parameter value.

�Software,� as used herein, includes but is not limited to one or more computer readable and/or executable instructions that cause a computer or other electronic device to perform functions, actions, and/or behave in a desired manner. The instructions may be embodied in various fauns such as routines, algorithms, modules or programs including separate applications or code from dynamically linked libraries. Software may also be implemented in various forms such as a stand-alone program, a function call, a servlet, an applet, instructions stored in a memory, part of an operating system or other type of executable instructions. It will be appreciated by one of ordinary skill in the art that the form of software is dependent on, for example, requirements of a desired application, the environment it runs on, and/or the desires of a designer/programmer or the like.
Where �Verror� is the valve step error, �Perror� is the pressure error, �Derror� is the pressure error difference between the present and the previous pressure error calculation, �Serror� is the summation of the pressure errors, and �P,� �D,� and �S� are constants. The �Verror� equation generally defines a Proportional Integral Derivative (hereinafter PID) servo controller. Generally, the constants of �P,� �D,� and �S� are selected after empirical study of the behavior of the system. Additionally, theoretical values can also be selected for the constants. This HD servo control is active substantially throughout the logic's operation, though intermittent operation may also be acceptable during portions of the patient's breathing states. As will be described, the logic utilizes various pressure settings for the PD controller to generate the proper pressure outputs given the effects of the patient's breathing characteristics on the system's performance.
TABLE 1 Breaths per minute T (% unloading) 0 −0.15 1 −0.15 2 −0.15 3 −0.15 4 −0.15 5 −0.15 6 −0.15 7 −0.10 8 −0.10 9 −0.10 10 0.00 11 0.00 12 0.10 13 0.10 14 0.12 15 0.15 16 0.17 17 0.20 18 0.23 19 0.25 20 0.26 21 0.28 22 0.30 23 0.32 24 0.34 25 0.37 26 0.37 27 0.37 28 0.37 29 0.37 30 0.37 In Table 1, each �Breaths per minute� value has a corresponding �T (% unloading)� value associated therewith in the form of values �X,� �Y,� and �Z�, which are typically equal to or less than 1. The �T (% unloading)� values can be the same or different for any given �Breaths per minute� value and determine how soon the unloading cycle starts with respect to the median valve step position. For example, a �T (% unloading)� value closer to 1 would raise the unload threshold to be higher away from the median valve step position, thus causing the triggering of a pressure reduction sooner with respect to valve step position. A �T (% unloading)� value closer to zero (0) would lower the unload threshold bringing it closer to the median valve step position, thus causing the triggering of a pressure reduction later with respect to the valve step position. Generally, the larger the �Breaths per minute� value, the larger the �T (% unloading)� value. It should also be noted that one or more �Breaths per minute� values may have the same or different �T (% unloading)� values associated therewith.
Unload Pressure=P set −[P set*((ΔV*V scale)/K)*S] where �Pset� is the medically prescribed positive pressure, �ΔV� is the change in valve step position defined by (Peak−Median), �Vscale� is a value selected from Table 2 (below) and is based on Pset, �K� is a constant (e.g., in the range of 2000-4000, such as 3000) and �S� is a constant in the range of 1-3 but can be smaller than 1 and larger than 3. If the logic desires to simply maintain the prescribed pressure due to certain operating conditions, the �S� constant may be set to 0 so that the unload pressure is equal to the prescribed pressure. The value of �Vscale� may be based on the prescribed pressure (Pset), for example, as shown in Table 2.
In block 724, the valve step position is adjusted in an attempt to have the sensed pressure follow the pressure settings of the determined control waveform for the pressure setting reduction down to the unload pressure setting. In other words, block 724 uses the same logic as blocks 706-714 because the active HD servo control is used to correct the valve step position as the pressure settings of the control waveform are used for the desired pressure setting. For example, each of the pressure settings defines a �Set Pressure� that is compared to the sensed pressure to generate a pressure error that is used by the active PID servo control.
