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: This disclosure describes systems and methods for piloting a pneumatic valve using one or more piezoelectric blowers. According to embodiments, the one or more piezoelectric blowers may be coupled to the pneumatic valve to form a small, light-weight pneumatic valve that may be placed proximal to a ventilated patient, e.g., at the patient wye or the patient interface. Due to the close coupling of the one or more piezoelectric blowers, the pneumatic valve has a substantially shorter response time than traditional pneumatically piloted valves. Moreover, when piezoelectric blowers are coupled to the pneumatic valve in parallel, response time may be further decreased. Additionally or alternatively, when piezoelectric blowers are coupled to the pneumatic valve in series, pilot pressure may be increased as a function of the number of piezoelectric blowers in the series.

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 displaying an indication of 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 history of the patient places the patient at risk of developing retinopathy of prematurity. The apparatus may also include a display unit configured to present an indication of a risk of prematurity in the patient when the processing unit determines that the oxygen saturation history of the patient places the patient at risk of developing retinopathy of prematurity, the indication comprising at least one of a number associated with the risk, an audible alarm, or a visual alarm.

Abstract: The present disclosure describes a mode of ventilation that makes an automatic determination of an appropriate mandatory breath type in response to one or more patient based criteria. Specifically, the ventilator during the delivery a mandatory breath type determines whether predetermined ventilatory criteria have been met. Based on the determination, the ventilator may deliver one of any number of mandatory breath types. Further, the present disclosure also combines the advantages of a hybrid mode of ventilation with this automatic determination of an appropriate mandatory breath type in response to one or more patient based criteria.

Abstract: This disclosure describes systems and methods for ventilating a patient with a tidal volume that adjusts based on patient compliance. The disclosure describes a novel breath type or setting for existing breath types, that automatically and continuously varies the delivered tidal volume based on patient compliance and/or other monitored parameters.

Abstract: Methods and system for determining a likelihood of possible retinopathy of prematurity and alerting a caregiver of such likelihood may employ oxygen saturation measurements. 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: Various embodiments of the present disclosure provide systems, methods and devices for respiratory support. As one example, a ventilation system is disclosed that includes a computer readable medium including instructions for operating in a hybrid mode. These instructions include measuring patient effort during a spontaneous breath type and deriving a neural inspiratory time from the measurements of patient effort. This neural inspiratory time is then set as the inspiratory for a breath of a mandatory breath type. If new patient effort measurements are received by the ventilator, the neural inspiratory time may be adjusted.

Abstract: The present disclosure combines the advantages of a hybrid mode of ventilation with an automatic determination of an appropriate spontaneous breath type in response to one or more patient based criteria. Specifically, when the ventilator is delivering a spontaneous breath type, a determination may be made as to whether predetermined ventilatory criteria have been met. Based on the determination the ventilator may deliver one of any number of spontaneous breath types.

Abstract: Various embodiments of the present disclosure provide systems, methods and devices for respiratory support. As one example, a ventilation system is disclosed that includes a computer readable medium including instructions executable by a processor to receive a measured pressure value and a net flow value. A patient effort value is calculated based on a relationship between patient effort, the measured pressure value and the net flow value. The instructions are further executable to calculate a gas delivery metric based on the computed patient effort to obtain a predetermined patient effort. Gas is then caused to be delivered consistent with the gas delivery metric.
