Abstract: A capnograph system may be used together with a ventilation system for a patient. The capnograph system may include a capnography module with a carbon dioxide detector, which may generate a carbon dioxide signal responsive to an amount of carbon dioxide detected within an air path of the ventilation system. A monitoring circuit may further detect a pressure within the air path. A processing component within the capnography module may generate a pressure signal responsive to the pressure detected in the air path. The pressure signal, alone or in combination with other signals such as the carbon dioxide signal, may be used to detect spontaneous breaths of the patient.

Abstract: A gas flow reversing element is disclosed that includes a main piece comprising an inflow region, a nozzle region and a mixing region, and further includes a branching piece. The inflow region connects a pressure connector to a closable outlet opening in the mixing region, the branching piece connecting the nozzle region to a line connector. With the outlet opening opened, gas flow flowing along a first flow path from the pressure connector through the nozzle to the outlet opening, generates a gas flow in the branching piece flowing along a second flow path from the line connector to the outlet opening. The reversing element further includes a bypass, closable by at least one closing element, connecting the pressure connector and the line connector so that a gas flow can flow along a third flow path via the inflow region, and bypass the nozzle via the bypass.

Abstract: A protective oxygen mask is disclosed herein. The mask includes a main body defining an exterior surface and an interior portion. At least one attachment structure defines a first loop extending from a first side of the main body and a second loop extending from a second side of the main body. At least a portion of one of the loops includes a hollow tube section communicative with an oxygen source. An interior tube communicative with the hollow tube section of the first loop extends at least partially into the interior portion of the main body. Accordingly, oxygen flows from the oxygen source, through said hollow tube section of one of the loops, into the interior hollow tube section, and finally, into the interior portion of the main body via a plurality of openings.

Abstract: A device is used to improve the standard of care for patients with physiologic or pathologic differences between regions of the lungs. Regional variations can occur between the left and right lungs, upper and lower lungs, different lobes in the lungs, or diffuse variation that does not follow a strict pattern. The device includes a method to quantify the differences between regions of the lungs. Quantification of regional variations in lung pathophysiology can be performed with a sensor, such as a pressure or gas concentration sensor, imaging scans, or alternative technology. This quantified parameter is used to regulate the gas flow to each lung region. One embodiment does this with a novel flow regulation mechanism for a double lumen endotracheal tube for compartmentalized lung ventilation where either the flow or pressure to the left and right lung can be varied with a flow regulation mechanism. The device has embedded software that is able to analyze the clinical parameters of the left and right lung in real-time, including advanced algorithms to provide improved clinical feedback to clinicians to allow them to provide the highest level of personalized and precision care to a patient.

Abstract: A high-flow respiratory therapy system includes a blender arranged to receive a first gas and a second gas and to output a combination thereof as a delivered gas to a patient respiratory interface, an airflow source for providing a flow of air to the blender as the first gas, a valve operable to provide oxygen gas from an oxygen gas source to the blender as the second gas, a heater operable to heat the delivered gas at the patient respiratory interface, a pulse oximeter, and a controller configured to execute a learning procedure in response to a trigger. The learning procedure may include varying a parameter of the airflow source, a parameter of the valve, and a parameter of the heater and determining a recommended parameter based on one or more measurements of the pulse oximeter. The controller may output a recommendation to adjust the recommended parameter.
