Estimating the term…
A system for measuring a time-dependent impedance waveform from a patient, and calculating a parameter from this waveform. A wearable mask is coupled to a positive airway pressure machine to deliver a flow of gas to the patient. An impedance sensor attached to the wearable mask measures the IPG and/or BR waveform. The sensor features a first drive electrode that injects a first electrical current into the region, and a first sense electrode that measures an electrical signal related to the first electrical current and blood flow in the region. A processing system runs computer code configured to: 1) receive a digital representation of the time-dependent impedance waveform; and 2) process the digital representation, or a signal calculated therefrom, to determine the parameter.
A system for monitoring a parameter from a patient, comprising:
The system of claim 2, wherein the parameter is a physiological parameter corresponding to the patient.
A system for monitoring an impedance parameter and an EMG parameter from a patient, comprising:
A wearable mask coupled to a continuous positive airway pressure (CPAP) machine and configured to deliver air at positive pressures to a patient, the wearable mask comprising an impedance sensor comprised entirely by the mask and configured to measure a time-dependent impedance waveform from a region on the patient using a first drive electrode configured to inject an electrical current into the region, a first sense electrode configured to measure an electrical signal related to the electrical current and blood flow in the region, and a processing component configured to analyze the electrical signal to determine a parameter from the patient.
