Abstract
A system is provided including a thoracic bio-impedance or bio-reactance (TBIR) analysis module, a photoplethysmograph (PPG) analysis module, and a cardiac output module. The TBIR module is configured to obtain TBIR information from a TBIR detector, and the PPG analysis module is configured to obtain PPG information from a PPG detector. The cardiac output module is configured to determine the cardiac output of a patient using the TBIR information and the PPG information.
Claims20
A system for determining a cardiac output of a patient, the system comprising:
- a thoracic bio-impedance or bio-reactance (TBIR) analysis module configured to obtain TBIR information from a TBIR detector;
- a photoplethysmograph (PPG) analysis module configured to obtain PPG information from a PPG detector;
- and
- a cardiac output module configured to determine the cardiac output of the patient using the TBIR information and the PPG information.
A method for determining a cardiac output of a patient comprising:
- obtaining thoracic bio-impedance or bio-reactance (TBIR) information from a TBIR detector configured to detect TBIR activity of the patient;
- obtaining photoplethysmographic (PPG) information from a PPG detector configured to detect PPG activity of the patient;
- determining, at a processing unit, the cardiac output of the patient using the TBIR information and the PPG information.
A tangible and non-transitory computer readable medium comprising one or more computer software modules configured to direct a processor to:
- obtain thoracic bio-impedance or bio-reactance (TBIR) information from a TBIR detector configured to detect TBIR activity of a patient;
- obtain photoplethysmographic (PPG) information from a PPG detector configured to detect PPG activity of the patient;
- determine a cardiac output of the patient using the TBIR information and the PPG information.
