A system and method for providing a therapeutic treatment, such as a flow of breathing gas, to a patient at variable treatment levels. A respiratory cycle monitor detects the patient's respiratory cycles and a control unit incrementally adjusts the treatment level from a first predetermined level to a second predetermined level over a first predetermined number of respiratory cycles. The amount of the incremental adjustment and the frequency of such adjustments over the course of the first predetermined number of respiratory cycles can be controlled to achieve a desired change in the therapeutic treatment over the course of the patient's respiration.

Method and apparatus for determining the state of entrainment between biological systems which exhibit oscillatory behavior such as heart rhythms, respiration, blood pressure waves and low frequency brain waves based on a determination of heart rate variability (HRV) and an evaluation of the power spectrum thereof. Entrainment reflects a harmonious balance between the two branches of the autonomic nervous system within the body. This internal state of heightened physiological efficiency enhances health and promotes optimal performance. According to one embodiment a method is used to determine the entrainment level based on an entrainment parameter related to HRV. The method first determines the power distribution spectrum (PSD) and then calculates an entrainment parameter (EP), which is a measure of the power distribution in the HRV spectrum. High EP values occur when this power is concentrated within a relatively narrow range of frequencies, and lower values when the power is distributed over a broader range of frequencies. In one embodiment, an apparatus is provided for monitoring the heart beat and presenting this information via a personal computer, handheld device, or other processing means.

wherein a) determination of the procedure position of the procedure region is based on movement data that includes information on the vital movements of the body parts that are caused by the vital functions, and/or b) determination of the position of a second body part subject to vital movement is based on the determined procedure position and information on the relative position between the first and the second body part subject to vital movement.

The invention relates generally to treatment of solid cancers. More particularly, the invention relates to enhancing synchrotron acceleration cycle usage efficiency by adjusting the synchrotron's acceleration cycle to correlate with a patient's respiration rate where efficiency refers to the duty cycle or the percentage of acceleration cycles used to deliver charged particles to the tumor. The system senses patient respiration and controls timing of negative ion beam formation, injection of charged particles into a synchrotron, acceleration of the charged particles, and extraction to yield delivery of the particles to the tumor at a predetermine period of the patient's respiration cycle. Independent control of charged particle energy and intensity is maintained during the timed irradiation therapy. Multi-field irradiation ensures efficient delivery of Bragg peak energy to the tumor while spreading ingress energy about the tumor.

A vegetative roof system includes modules for holding growth media in which plants can grow. The modules can communicate with each other, sharing moisture/nutrients, increasing airflow to enhance plant respiration, allowing soil-borne animals/insects to travel between modules, etc. A rooting channel and/or a scalloped sidewall allow the roots of plants in the module to extend to adjacent modules. Alignment notches in sidewalls facilitate alignment of rooting channels between adjacent modules. Vertical zones help facilitate placement of abutting modules flush with each other. The rooting channels may be formed at the vertical zones to enhance continuity between and among modules. Sheet inserts can control rooting between modules and restrict undesired spillage through rooting channels (temporarily if biodegradable). Module inserts help control the quantity and depth of growth media, affecting module weight and rooting levels. An elevated connector can secure two or more modules together using downwardly-radiating prongs.

A method detects and interprets myoelectrical activity from an intra-abdominal organ. Electrodes obtain first signals over time relating to myoelectrical activity of organ. A respiration sensor obtains second signals relating to respiration of the patient. An initial parameter range of the first and second signals is established. A processor determines minutes when artifact occurs in both the first and second signals based on the initial parameter range. It is then determined whether there are artifact free minutes of the first and second signals. A condition of the patient is changed after determining that there are sufficient artifact free minutes. The first and second signals are recorded in memory simultaneously for a period of time after changing the condition of the patient. A processor determines whether artifact occurs in the recorded first and second signals. Artifact free minutes of the recorded first and second signals are selected for analysis. Via the processor, the selected minutes are analyzed to automatically determine a condition of the organ.
