Abstract
Multiple different output signals for a polysomnograph (PSG) machine, the multiple different output signals including a first output indicative of an upper airway restriction (UAR), a second output indicative of an airway pressure during respiration, and a third output indicative of an airway air temperature during respiration, can be produced using a single sensor input.
Claims20
An apparatus for creating multiple filtered outputs for a polysomnograph (PSG) machine from a single sensor input, comprising:
- an electronic signal processing circuit configured to receive a single sensor input and to produce, using the single sensor input, multiple different output signals, the multiple different output signals including:
- a first output indicative of an upper airway restriction (UAR);
- a second output indicative of an airway pressure during respiration;
- and
- a third output indicative of an airway air temperature during respiration.
A system for creating multiple filtered outputs for a polysomnograph (PSG) machine from a single sensor input, comprising:
- a piezo/pyro sensor, sized and shaped to be affixed to a subject's upper lip, the piezo/pyro sensor configured to receive respiration information from the subject;
- an electronic signal processing circuit configured to receive information from the piezo/pyro sensor and to produce, using the piezo/pyro sensor input, multiple different output signals, the multiple different output signals including:
- a first output indicative of an upper airway restriction (UAR);
- a second output indicative of an airway pressure during respiration;
- and
- a third output indicative of an airway air temperature during respiration;
- and
- a polysomnograph (PSG) machine configured to receive the multiple different output signals from the electronic signal processing circuit and to display information about at least one of the received first output, the received second output, or the received third output to a user.
A method for creating multiple filtered outputs for a polysomnograph (PSG) machine from a single sensor input, comprising:
- receiving a single sensor input;
- producing, using the single sensor input, multiple different output signals, the producing including:
- producing a first output indicative of an upper airway restriction (UAR);
- producing a second output indicative of an airway pressure during respiration;
- and
- producing a third output indicative of an airway air temperature during respiration.
