11. The system of claim 9 , wherein the output signal is configured to cause the ultrasound transducer to emit an ultrasound beam at an intensity from 0.2 to 4.5 Watts per square centimeter (W/cm 2 ).
12. The system of claim 1 , wherein the at least one processor comprises a mobile terminal.
13. The system of claim 1 , wherein the organ comprises a hypoglossal nerve.
14. The system of claim 1 , wherein the organ stimulating transducer is configured for placement adjacent to a throat of the subject.
15. A method for treating an obstruction in a subject suffering from obstructive sleep apnea (OSA), the method comprising:
placing an organ stimulating transducer on the subject in a vicinity of an organ of the subject, with the placement of the organ stimulating transducer being external the subject, and with the organ stimulating transducer configured to identify a location of the organ to be stimulated via a location of Ranine veins of the subject,
placing a first sensor on a body of the subject, the first sensor configured to obtain first data representative of a blood oxygen saturation level of the subject to detect a hypoxic condition in the subject;
receiving automatically on a processor first data from the first sensor configured to collect automatically the first data, wherein the first data is sensitive to the hypoxic condition;
receiving automatically on the processor second data indicative of an obstruction in an airway of the subject;
determining on the processor whether the subject is in the hypoxic condition during the obstruction of the airway of the subject based on the first data and the second data, wherein when it is determined that the subject is in the hypoxic condition during the airway obstruction, sending an output signal to the organ stimulating transducer to stimulate the organ of the subject based on the identified location.
16. The method of claim 15 , wherein the organ comprises the hypoglossal nerve.
17. The method of claim 15 , wherein the organ stimulating transducer comprises an ultrasound transducer.
18. The method of claim 17 , further comprising automatically sending, to the ultrasound transducer upon detecting the subject is in the hypoxic condition during the obstruction of the airway of the subject, a signal that causes the ultrasound transducer to obtain a plurality of images of the airway of the subject.
19. The method of claim 18 , further comprising, wherein the processor is configured to
confirm the obstruction in the airway of the subject based on the plurality of images.
20. The method of claim 19 , wherein the confirmation is provided to user via a visual or audible device.
21. The method of claim 17 , wherein the output signal causes the ultrasound transducer to emit an ultrasound beam at a frequency of less than 12 MHz.
