Benefits of technology

The patent describes a system to monitor a patient's blood flow to diagnose their health. It measures the patient's blood flow during a basal period when they are not exposed to any electromagnetic signals and then again during an exposure period when they are exposed to low-energy electromagnetic signals. The system uses an electrically-powered generator to generate these signals. The technical effect is that this system can help diagnose health conditions by measuring the impact of low-energy electromagnetic signals on the patient's blood flow.

Problems solved by technology

This disclosure, however, does not contemplate or suggest employing measured Hdp values as a means for diagnosis of either a type of cancer or indeed any other form of a health condition of a patient.

[0042]The following Table 2 is exemplary Principal Component (PC) values, representative of a multiple number of sensed and recorded hemodynamic parameter values for each of the nine values of a number of patients. The PC representative values are divided into three groups: Pressure, Flow and Beat for three groups each of 8 patients, respectively 8 patients with hepatocellular carcinoma (HCC), 8 patients with breast cancer, and 8 healthy controls for simplifying comparisons of PC Hdp values between patients with a diagnosis of HCC or breast cancer and healthy controls. Also included in the following Table is reference to X and Y canonical coordinates obtained by the Fisher's discriminant analysis, representative pressure, flow and beat PC values of Hdp's exhibited by patients before exposures or applications of EM AM signals:

Abstract

A hemodynamic parameter (Hdp) monitoring system for diagnosing a health condition of a patient and for establishing Hdp marker values or Hdp surrogate marker values for purposes of comparison with Hdp values of a patient is provided. An Hdp monitor senses, measures, and records Hdp values exhibited by the patient during a basal or non-exposure period and furthermore Hdp values exhibited by the patient during or after an exposure period during which the patient is exposed to low-energy electromagnetic output signals. An electrically-powered generator is adapted to be actuated to generate said low-energy electromagnetic carrier output signals for exposing or applying to the patient such output signals during said exposure period.

Description

FIELD OF THE INVENTION[0001]This invention relates to a hemodynamic parameter (Hdp) monitoring system for diagnosis, more particularly involving a monitor able to sense and monitor various specified Hdp values and providing recorded values thereof. The recorded specified Hdp values include values required for purposes of performing diagnoses in terms of the invention.BACKGROUND OF THE INVENTION AND STATE OF THE ART[0002]Various Hdp monitors are available in the art. Such monitors are generally employed to sense and monitor various Hdp values, usually for purposes of diagnosing cardiovascular conditions of a patient. Hdp measurements performed, generally in conjunction with an electrocardiogram (ECG), might include measurements of stroke volume (SV), stroke index (SI) and cardiac output (CO). Such measurements are indicated for the diagnosis and therapy of patients suffering from cardiac conditions such as heart failure, hypertension, coronary artery disease, pericardial disease, obs...
