Abstract: Embodiments of the present disclosure relate to determining a likelihood of possible retinopathy of prematurity and alerting a caregiver of such likelihood. According to certain embodiments, an apparatus for determining a risk of retinopathy of prematurity in a patient may include a processing unit. The processing unit is configured to determine whether an oxygen saturation level of the patient extends beyond an oxygen saturation threshold, determine an extent that the oxygen saturation level of the patient extends beyond the oxygen saturation threshold, and trigger an alarm when the extent that the oxygen saturation level of the patient extends beyond the oxygen saturation threshold exceeds a threshold at which the patient may be at risk of developing retinopathy of prematurity. The apparatus may also include a display unit configured to present the alarm in response to the trigger from the processing unit.

Abstract: The disclosure describes a novel approach for displaying information on a ventilator system. The disclosure describes a novel respiratory system including a primary display and system status display. Further, the disclosure describes a novel method for displaying ventilator information.

Abstract: This disclosure describes systems and methods for conducting and terminating spontaneous breathing trials on patients receiving mechanical ventilation. The disclosure describes a novel spontaneous breathing trial manager for a medical ventilator with rapid initiation and continuous monitoring of a patient's tolerance of the spontaneous breathing trial and displaying of that tolerance as a function of time, which provides for bedside adjustment of the spontaneous breathing trial parameters and automatic termination of a spontaneous breathing trial based on a time interval expiration or poor patient tolerance of the SBT.

Abstract: According to various embodiments, a tracheal tube may include an integral humidification system. The tracheal tube may be formed at least partially from a material that is permeable to water vapor but substantially impermeable to respiratory gases. The water vapor may be actively provided to the tracheal tube or may be passively transferred from a patient's surrounding airway space.

Abstract: In one exemplary embodiment, an EMI shield assembly generally includes a frame adapted to be secured to a mounting surface, a cover attachable to the frame, and at least one resilient electrically-conductive member disposed on an inner side of the cover. The at least one resilient electrically-conductive member may be configured to contact at least one electrically-conductive surface on the mounting surface, to establish a current-conducting path from the electrically-conductive surface to the cover when the cover is attached to the frame. The at least one resilient electrically-conductive member may be configured to be compressed against at least one electrically-conductive surface on the mounting surface when the cover is attached to the frame. This compression may help provide an effective amount of contact pressure against the at least one electrically-conductive surface to establish a predetermined or desirable level of electrical conductivity.

Abstract: Similar, contiguous primitives are stored as a single primitive in zone rendering bins. A primitive packet used in the bin is allowed to vary in length and the currently open type of primitive is recorded on a per-bin basis. A special code is used to specify a variable number of subsequent indices. With this mechanism, the hardware is able to start outputting and replicating primitive commands into bin lists on the fly without requiring the buffering of the entire primitive. Given the variable nature of the primitive instruction, multiple similar/sequential primitives can be concatenated using a single primitive command header.

Abstract: A machine readable storage media containing executable program instructions which when executed cause a digital processing system to set a plurality of operands and operators. A plurality of texture maps are sent to a processor for texture compositing. Operands are selected for a texture operation. A first logic is used wherein if the circulation of blend stages is equal to a number of blend stages, then a color saturation is performed, and a second logic that if the circulation number of blend stages does not equal the number of blend stages then at least one operand is selected for another texture compositing operation.

Abstract: A breathing support system is provided. The system may include a breathing support device configured to deliver gas to a patient and a display device associated with the breathing support device. The display device may be configured to display a work of breathing graphic indicating one or more work of breathing measures regarding the patient's breathing.

Abstract: An apparatus for making a wet roll including a body of a roll of wet wound sheet material, where the body of the roll is connected to a tail of the roll, means for applying an adhesion promoter between the body and the tail and means for contacting the body and the tail. The body and tail of the roll contain a wetting solution.

Abstract: A ventilator of the present invention includes a housing, a gas flow generator disposed in the housing, a gas outlet port provided on an exterior surface of the housing, and a first conduit coupling the gas flow generator to the gas outlet port. A gas inlet port is also provided on an exterior surface of the housing. A second conduit couples the gas inlet port to a first exhaust valve in the housing that regulates a flow of exhaust gas from the second conduit. A second exhaust valve in the housing is coupled to the first conduit and regulates a flow of exhaust gas from the first conduit. A controller coupled to second exhaust valve causes the second exhaust valve to change a degree of flow restriction based on a respiratory phase of a patient coupled to the ventilator when the ventilator is operating in a single-limb ventilation configuration.

Abstract: A method of making wet rolls includes providing a web of material, applying a wetting solution to the web to produce a wet web, and winding the wet web into a roll. The wetting solution may include an inorganic salt and at least one preservative. The wetting solution may be distributed evenly throughout the wet roll.

Abstract: A method of making wet rolls includes providing a web of material, applying a wetting solution to the web to produce a wet web, and winding the wet web into a roll. The wetting solution may be applied at an add-on greater than 25%, and the web may travel at a speed of at least 60 meters per minute.

Abstract: An image is rendered by dividing the image into chunks, rendering the chunks in one of at least two devices, and determining which of the devices renders each one of at least some of the chunks based on at least one device's progress in the rendering of other chunks.

Abstract: A method, apparatus, and system to concurrently render independent images for display on one or more display devices. In an embodiment, a graphics-rendering engine concurrently renders independent images for display on multiple display devices. A time allocator arbitrates the concurrent use of the graphics-rendering engine between each independent image being rendered.

Abstract: A method of making a wet roll includes providing a body of a roll of wet wound sheet material, where the body of the roll is connected to a tail of the roll, applying an adhesion promoter between the body and the tail, and contacting the body and the tail. The body and tail of the roll contain a wetting solution.

Abstract: The system and method for detecting disconnection and occlusion of a tubing system of a patient ventilator detects disconnection of the tubing system, opens the exhalation valve, delivers an idle flow of breathing gas to the tubing system, disables breath triggering, and generates an alarm. A reconnection of the tubing system can also be detected, to initiate resumption of pressure supported inspiration. For occlusion detection, the pressure drop in the tubing system is determined by pressure sensors in the inspiratory and expiratory airways of the tubing system. The two pressure drop values are compared, and once occlusion is detected, an alarm is generated, and the ventilator responds to protect the patient from over distension. Abatement of the occlusion can also be monitored in a pressure based occlusion status cycling mode, and the ventilator can revert back to normal ventilation when either circuit occlusion or exhaust port occlusion are not detected.
