초록 ▼

A respiratory assistance device is disclosed. There is a patient interface for coupling to a patient respiratory passageway, and a selectively regulated therapeutic gas flow source in pneumatic communication with the patient over the patient interface. A controller is connected to the therapeutic gas flow source and is receptive to inputs of a prescription pressure level and an initial delay duration. After the patient dons the patient interface, therapeutic gas flow is restricted for the initial delay duration following receipt of a treatment initiation command. Upon the expiry of the initial delay duration, the controller increases therapeutic gas flow to the prescription pressure level.

1. A respiratory assistance device, comprising: a patient interface for coupling to a respiratory passageway of a patient;a selectively regulated therapeutic gas source in pneumatic communication with the patient over the patient interface; anda controller connected to the therapeutic gas source and receptive to inputs of a prescription pressure level and an initial delay duration, delivery of therapeutic gas from the therapeutic gas source being restricted for the initial delay duration following receipt of a treatment initiation command, followed by an increase in therapeutic pressure to the prescription pressure level;wherein the increase in the therapeutic pressure to the prescription pressure level is controlled over a predetermined ramp duration;wherein the therapeutic pressure is increased to a ramp base pressure level by the controller after expiration of the initial delay duration, the increase in the therapeutic pressure to the prescription pressure level beginning at the ramp base pressure level;wherein the therapeutic pressure is maintained at the ramp base pressure level by the controller after expiration of the initial delay duration for a ramp delay duration, the ramp delay duration being a predetermined amount of time adjustable by a user. 2. The respiratory assistance device of claim 1, wherein the patient interface includes a piloted exhalation valve that permits airflow to and from the respiratory passageway associated with spontaneous breathing while the delivery of therapeutic gas is being restricted. 3. The respiratory assistance device of claim 1, further comprising: a first pressure sensor in fluid communication with the patient interface; anda second pressure sensor in fluid communication with an output of the selectively regulated therapeutic gas source. 4. An article of manufacture comprising a program storage medium readable by a data processing apparatus, the medium tangibly embodying one or more programs of instructions executable by the data processing apparatus to perform a method for delivering therapeutic gas to a patient with a respiratory assistance device, the method comprising: receiving from the respiratory assistance device a prescription pressure level and a numeric value corresponding to a zero pressure delay duration;receiving from the respiratory assistance device a treatment initiation command following the patient being pneumatically coupled to the respiratory assistance device over a patient interface;restricting gas delivery from the respiratory assistance device to the patient interface at a zero pressure level for the zero pressure delay duration in response to receiving the treatment initiation command; andinitiating gas delivery from the respiratory assistance device to the patient interface at the prescription pressure level after expiration of the zero pressure delay duration;wherein the gas delivery to the patient interface after expiration of the zero pressure delay duration is gradually increased to the prescription pressure level over a ramp duration based upon a ramp function;wherein gas delivery to the patient interface is increased to a ramp base pressure level after expiration of the zero pressure delay duration;wherein gas delivery to the patient interface is maintained at the ramp base pressure level after expiration of the zero pressure delay duration for a ramp delay duration, the ramp delay duration being a predetermined amount of time adjustable by a user. 5. The article of manufacture of claim 4, wherein the zero pressure delay duration corresponds to a predetermined time period for the patient to enter a sleep state. 6. The article of manufacture of claim 4, wherein the method further comprises: receiving from the respiratory assistance device a numeric value corresponding to the ramp duration. 7. The article of manufacture of claim 4, wherein the method further comprises: receiving from the respiratory assistance device a numeric value corresponding to the ramp delay duration. 8. A system comprising: the article of manufacture of claim 4; andthe patient interface, wherein the patient interface includes a piloted exhalation valve through which the patient inhales and exhales spontaneously while gas delivery from the respiratory assistance device is restricted during the zero pressure delay duration.
