20110297155 | PATIENT-VENTILATOR DYSSYNCHRONY DETECTION - A method of detecting dyssynchrony between a patient and a pressure support system includes receiving patient flow data relating to a flow of gas provided to the patient by the pressure support system, receiving an I/E state signal representing a respiratory phase of the patient as determined by the pressure support system, and analyzing the patient flow data and the I/E state signal and declaring a dyssynchrony for a breath based on at least one of the patient flow data and the I/E state signal. The method includes determining whether at least one of a number of predetermined criterion is satisfied based on at least one of the patient flow data and the I/E state signal, and declaring the dyssynchrony for the breath if it is determined that at least one of the number of predetermined criterion is satisfied. | 12-08-2011 |
20110297156 | AUTOMATIC PRESSURE TITRATION - A pressure support methodology and system that utilizes at least two, and possibly all three, of information relating to (i) airway patency, i.e., the degree to which the patient's airway is open, (ii) the primary cause of the current sleep disordered breathing event, and (iii) the patient's response to previous pressure changes to automatically titrate pressure when presented with a sleep disordered breathing event. In another embodiment, pressure may be automatically titrated based solely on the primary cause of the sleep disordered breathing event. | 12-08-2011 |
20110303223 | PRESSURE SUPPORT SYSTEM WITH MACHINE DELIVERED BREATHS - A method of operating a ventilator or pressure support system that automatically determines a timed back up rate for the patient based on the patient's spontaneous breathing patterns. The aggressiveness of the determined rate increases as the patient takes less spontaneous breaths. Also, a method wherein one or more mechanisms are used to determine whether a machine breath should be issued. Each mechanism consists of a basic timing element coupled with one or more logical permits. Both the timing element and each of the one or more logical permits must be satisfied to allow the timing mechanism to trigger a machine breath. | 12-15-2011 |

20120235312 | HUMIDITY CONTROL IN APRESSURE SUPPORT SYSTEM - A pressure support system configured to provide pressure support therapy includes a humidifier that holds an enhanced amount of liquid while enhancing the power consumption of the pressure support system and enabling relatively rapid adjustments to humidity level. The humidifier includes a humidification chamber and a holding chamber, and a partition that divides the holding chamber from the humidification chamber such that liquid from the holding chamber replenishes liquid held in the humidification chamber. The partition, however, also provides a level of thermal isolation for the humidification chamber from the holding chamber. | 09-20-2012 |
20120298108 | AUTOMATICALLY CONTROLLED VENTILATION SYSTEM - A system for controlling and regulating breathing gas supplied to a patient that includes a pressure generator system that provides breathing gas to a patient and a patent circuit that delivers the breathing gas to the patient. The system includes an interface device coupled to the patient circuit to communicate the flow of gas to the patient' airway. A sensor detects a parameter indicative of a flow of breathing gas delivered to the patient. A controller coupled to the sensor and the pressure generator system measures at least one characteristic of respiratory airflow of a patient and calculates a target breath-amplitude-based parameter and a time-based parameter of at least a portion of the patient's respiratory cycle to be delivered to the patient based on the at least one characteristic of respiratory airflow. | 11-29-2012 |

20130239965 | HUMIDIFICATION SYSTEM WITH SIGNAL TRANSMISSION OPTIMIZATION - A pressure support device configured to provide pressure support therapy includes a humidifier that holds an enhanced amount of liquid without significantly mitigating sensitivity of respiratory event detection. The humidifier includes a chamber configured to hold liquid, and a partition that divides the chamber such that the volume of the chamber through which a flow of gas generated by the pressure support device flows is reduced. The reduction in the volume of the chamber through which the flow of gas flows preserves respiratory event detection sensitivity. | 09-19-2013 |
20130340751 | MEASURING CONTINUITY OF THERAPY ASSOCIATED WITH A RESPIRATORY TREATMENT DEVICE - Continuity of therapy associated with a respiratory treatment device may be measured. Information relating to therapy administered via the respiratory treatment device to a subject during a therapy session may be received. Based on the received information, a quantity of therapy interruption events that occurred during the therapy session may be determined. A continuity indicator may be determined based on the quantity of therapy interruption events that occurred during the therapy session. The continuity indicator is indicative of continuity of therapy associated with the respiratory treatment device during the therapy session. | 12-26-2013 |
20140109909 | PRESSURE ADJUSTMENT IN A RESPIRATORY THERAPY DEVICE - Sleep apnea can be treated with pressure support therapy using a target pressure level. Detected respiratory events during consecutive multi-session testing period are compared to determine statistical metrics covering gradual changes in therapy efficiency. Adjustments to the target pressure level are based on changes in variability, and maybe made in between therapy sessions. | 04-24-2014 |
20150040903 | STARTING PRESSURE FOR RESPIRATORY THERAPY DEVICES - Systems and methods for providing respiratory therapy to a subject respond and/or adapt to the detection of an occurrence of a respiratory event. For example, the pressure level of a pressurized flow of breathable gas may be increased responsive to the occurrence of one or more apneas. Based on usage information spanning more than one therapy session, such as the tracked pressure levels, a starting pressure level for a pressurized flow of breathable gas for a subsequent therapy session is determined. The starting level at the beginning of the subsequent therapy session(s) may be the 90% pressure level as determined during the preceding period during which usage information has been gathered. | 02-12-2015 |
