SYSTEMS AND METHODS FOR PROVIDING VENTILATION BASED ON PATIENT NEED
A ventilation system includes a controller and an alarm module in communication with the controller. The alarm module includes an alarm and an alarm emitter indicating activation of the alarm, wherein the alarm may be one or more of the following alarms: low pressure, low volume, low respiration rate, low minute volume, disconnect condition, and apnea. When the controller is in a first mode setting, the alarm emitter is activated in response to a triggering event, and when the controller is in a second mode setting, the alarm emitter is not activated in response to the triggering event. The ventilation system may include a breathing circuit, an airflow generator for delivering a ventilation airflow to the breathing circuit, and a sensor for sensing an increase in at least one of an air flow or an air pressure within the breathing circuit, thus triggering airflow.
1 . A ventilation system comprising:
a controller comprising a first mode setting and a second mode setting;
an alarm module in communication with the controller, the alarm module comprising an alarm and an alarm emitter indicating activation of the alarm, wherein the alarm is selected from the group consisting of a low pressure alarm, a low volume alarm, a low respiration rate alarm, a low minute volume alarm, a disconnect alarm, and an apnea alarm;
wherein when the controller is in the first mode setting, the alarm emitter is activated in response to a triggering event, and wherein when the controller is in the second mode setting, the alarm emitter is not activated in response to the triggering event.
2 . The ventilation system of claim 1 ,
wherein when the controller is in the first mode setting, the controller sends an alarm signal to the alarm module based on the triggering event, wherein the alarm signal activates the alarm emitter, and
wherein when the controller is in the second mode setting, the controller does not send the alarm signal to the alarm module based on the triggering event.
3 . The ventilation system of claim 2 , further comprising a sensor in communication with the controller, wherein the triggering event comprises a signal sent by the sensor to the controller.
4 . The ventilation system of claim 3 , triggering event comprises a signal having a value outside of a predetermined range.
5 . The ventilation system of claim 1 ,
wherein when the controller is in the first mode setting, the controller sends an alarm signal to the alarm module based on the triggering event, wherein the alarm signal activates the alarm emitter, and
wherein when the controller is in the second mode setting, the controller does not send the alarm signal to the alarm module based on the absence of the triggering event.
6 . The ventilation system of claim 5 , further comprising a sensor in communication with the controller, wherein the triggering event comprises a signal sent by the sensor to the controller.
7 . The ventilation system of claim 1 , further comprising a sensor in communication with the controller,
wherein when the controller is in the first mode setting, the sensor sends a signal to the controller, and
wherein when the controller is in the second mode setting, the sensor does not send the signal to the controller, and
wherein the controller activates the alarm emitter based on receipt of the signal.
8 . The ventilation system of claim 1 , further comprising a power module in communication with the controller,
wherein when the controller is in the first mode setting, the power module energizes the alarm emitter, and
wherein when the controller is in the second mode setting, the power module does not energize the alarm emitter.
9 . A method of controlling an alarm state in a ventilation system comprising a controller, a power module, a sensor module, and an alarm emitter activated by at least one of a low pressure signal and a low volume signal, the method comprising the step of
programming the ventilation system to comprise an on-demand ventilation mode, wherein in the on-demand ventilation mode, the alarm emitter is not activated.
10 . The method of claim 9 , wherein when in the on-demand ventilation mode, the controller does not send an alarm signal to the alarm emitter.
11 . The method of claim 9 , wherein when in the on-demand ventilation mode, the power module does not deliver power to the alarm emitter.
12 . The method of claim 9 , wherein when in the on-demand ventilation mode, the sensor module does not send a signal to the controller.
13 . The method of claim 9 , wherein when in the on-demand ventilation mode, the sensor module sends a signal to the controller, wherein the signal does not meet a predetermined threshold value.
14 . The method of claim 9 , wherein when in the on-demand ventilation mode, the power module does not deliver power to the sensor module.
15 . A ventilation system comprising:
a breathing circuit;
an airflow generator for delivering a ventilation airflow to the breathing circuit; and
a sensor for sensing at least one of an air flow or air pressure within the breathing circuit, wherein the ventilation airflow is delivered to the breathing circuit upon an increase in at least one of the air flow and the air pressure.
16 . The ventilation system of claim 15 , further comprising a patient interface defining an opening, wherein the patient interface is connected to the breathing circuit.
17 . The ventilation system of claim 16 , wherein the increase at least one of the air flow and the air pressure is caused by a patient forcing air into the interface.
18 . The ventilation system of claim 16 , wherein the increase at least one of the air flow and the air pressure is caused by a patient orally latching on to the interface,
19 . The ventilation system of claim 16 , wherein the increase at least one of the air flow and the air pressure is caused by a patient at least partially blocking the opening.
20 . The ventilation system of claim 16 , wherein the increase at least one of the air flow and the air pressure is caused by a patient at least partially obstructing a biasing airflow through the opening.
