A method of deriving one or more individual thoracic parameters of a subject. The method comprises instructing a subject to perform a thoracic volume manipulation, receiving a plurality of measurements of a plurality of EM signals from a thoracic intrabody area of lungs of the subject during the thoracic volume manipulation, deriving a plurality of thoracic volume values at a plurality of different intervals during the thoracic volume manipulation so that each the thoracic volume value correspond with another of a plurality of estimated thoracic volumes achieved during the thoracic volume manipulation, and calculating at least one individual thoracic parameter of the subject by combining between the plurality of measurements and the plurality of thoracic volume values.

Deriving individual thoracic parameters of a subject

A method for diagnosis includes receiving a signal associated with blood oxygen saturation of a patient during sleep. The signal is filtered so as to eliminate signal components at frequencies equal to and greater than a respiratory frequency of the patient. The filtered signal is processed to detect a pattern corresponding to multiple cycles of periodic breathing.

Detection of heart failure using a photoplethysmograph

A method for diagnosis includes receiving a signal associated with respiration of a patient during sleep, and processing the signal to detect occurrences of a pattern corresponding to multiple cycles of periodic breathing. A cumulative duration of the occurrences is computed, and a prognosis of the patient is determined based on the cumulative duration.

Respiration-based prognosis of heart disease

A method for diagnosis includes receiving from a sensor coupled to a body of a patient a photoplethysmograph signal, which is indicative of blood flow in the body. The photoplethysmograph signal is processed so as to identify at least one irregularity in a heart rhythm of the patient. A record indicating a time of occurrence of the at least one irregularity is made and processed so as to diagnose a pathological cardiac condition of the patient.

Detection of cardiac arrhythmias using a photoplethysmograph

A method for diagnosis includes receiving from a sensor coupled to a body of a sleeping patient a photoplethysmograph signal. The photoplethysmograph signal is processed independently of any other physiological measurements in order to identify sleep stages of the patient.

Sleep monitoring using a photoplethysmograph

A method for diagnosis of a sleep-related condition of a patient having a thorax. The method includes receiving physiological signals from sensors coupled to the thorax of the patient, and analyzing the physiological signals, independently of any electroencephalogram (EEG) or electro-oculogram (EOG) signals, in order to identify sleep stages of the patient.
