System and method for diagnosis and treatment of a breathing pattern of a patient
Described is a system including a sensor and a processing arrangement. The sensor measures data corresponding to a patient's breathing patterns. The processing arrangement analyzes the breathing patterns to determine whether the breathing patterns are indicative of a REM sleep state. In another embodiment, the processing arrangement analyzes the breathing patterns to determine whether the breathing patterns are indicative of one of the following states: (i) a wake state and (ii) a sleep state. In another embodiment, a neural network analyzes the data to determine whether the breathing patterns are indicative of one of the following states: (i) a REM sleep state, (ii) a wake state and (iii) a sleep state. In another embodiment, the processing arrangement analyzes the data to determine whether the breathing pattern is indicative of an arousal.
1. A system, comprising:
a sensor measuring data corresponding to a patient's breathing patterns; and
a neural network analyzing the data to determine which of the following states the detected breathing pattern is indicative of: (i) a REM sleep state, (ii) a non-troubled wake state, (iii) a non-REM sleep state and (iv) a troubled wakefulness state.
2. The system according to claim 1 , wherein the breathing patterns indicative of the REM sleep state include at least one of (i) an absence of large breaths, (ii) a high respiratory rate, (iii) a low flow rate and (iv) a cluster of small breaths.
3. The system according to claim 1 , further comprising:
a generator supplying airflow and applying a pressure to an airway of a patient; and
a processing arrangement adjusting the pressure as a function of the state.
4. The system according to claim 3 , wherein the pressure is zero.
5. The system according to claim 3 , wherein when the breathing pattern is indicative of the non-troubled wake state, the processing arrangement decreases the pressure.
6. The system according to claim 3 , wherein when the breathing patten is indicative of the non-REM sleep state, the processing arrangement decreases the pressure.
7. The system according to claim 3 , wherein when the breathing pattern is indicative of the REM sleep state, the processing arrangement increases the pressure.
8. The system according to claim 3 , further comprising:
a mask coupled to the generator covering at least one of a nose and a mouth of the patient.
9. The system according to claim 8 , further comprising:
a venting arrangement coupled to the mask preventing a re-breathing of exhaled gas.
10. The system according to claim 3 , wherein the processing arrangement determines a time period during which the breathing patterns are indicative of the non-REM sleep state.
11. The system according to claim 3 , wherein the processing arrangement determines whether the breathing pattern is indicative of an arousal.
12. The system according to claim 3 , wherein when the breathing pattern is indicative of the troubled wakefulness state, the processing arrangement decreases the pressure.
13. A system, comprising:
a sensor measuring data corresponding to a patient's breathing patterns; and
a neural network analyzing the data to determine which of the following states the breathing pattern is indicative of: (i) a REM sleep state, (ii) a non-troubled wake state, (iii) a non-REM sleep state, (iv) an arousal and (v) a troubled wakefulness state.
14. The system according to claim 13 , wherein the breathing pattern indicative of the arousal includes a large breath during a period of regular breathing.
15. The system according to claim 14 , wherein the large breath is about 3-5 seconds long.
16. The system according to claim 13 , further comprising:
a generator supplying airflow and applying a pressure to an airway of the patient; and
a processing arrangement adjusting the pressure as a function of the state; wherein, when the breathing patten is indicative of the non-REM sleep state, the processing arrangement decreases the pressure and wherein, when the breathing pattern is indicative of the REM sleep state, the processing arrangement increases the pressure.
