Problems solved by technology

In addition, interpretation of the various cardiac tests is difficult, and in the early stages of cardiac deterioration, the physician who sees the patient is often not a trained cardiologist but a general practitioner (GP) and / or a specialist Physicians in other fields

Embodiment Construction

[0018] refer to figure 1 , a human subject 10 (such as an inpatient admitted to a hospital, or a nursing center resident, or an outpatient, etc.) is monitored by a patient monitor 12 comprising a display device or component 14, a microprocessor A monitor or microcontroller (not shown, but typically housed in monitor housing 16) and a plurality of physiological (i.e., vital sign) sensors 20, 22, 24 (such as the illustrative set of electrocardiogram electrodes 20), Pulse oximeter sensor 22 (not connected in the illustration, but typically clipped to the finger or earlobe of subject 10 ) and air flow sensor 24 . in pictorial figure 1 Among them, the air flow sensor 24 is mounted in a full face mask 26 used for mechanical ventilation, sleep apnea management, general respiratory monitoring, and the like. In other embodiments, the air flow sensor 24 may be installed in conjunction with a nasal mask or nasal cannula, or the like. In general, patient monitor 12 may be in one of a v...

Abstract

A patient monitor (12) includes a display (14) and sensors (20, 22, 24) for reading vital signs of a human subject. In the Cardiovascular Early Warning Score (cEWS) method, human subjects are classified using multiple cardiovascular worsening classifiers (52, 152, 54, 56, 58), each with respect to a different types of cardiovascular deterioration while being trained. The cardiovascular deterioration classifier operates on a set of inputs characterizing the human subject, the set of inputs including at least one cardiovascular parameter (42) and at least A breathing parameter (44). A cardiovascular early warning score for different types of cardiovascular deterioration is output on the display of the patient monitor. The empirical myocardial ischemia classifier (52) can be combined with at least one additional ischemia score generated by applying a set of rules (160) or a physiological model (162).

Description

technical field [0001] The following generally relate to cardiac care technology, medical emergency response technology, and more. Background technique [0002] There may be many clinical conditions, which may or may not be indicative of the occurrence of cardiac deterioration, such as a patient with one or more of the following symptoms: dizziness; weakness; fast or irregular heartbeat; shortness of breath; chest discomfort; . Such symptoms are common symptoms of cardiovascular disease in patients with potential risk of cardiac arrest, acute heart attack, or acute heart failure when symptoms are severe, or irregular heart rhythm or coronary artery disease potential when symptoms are not severe risk. Typical scenarios of cardiac deterioration are likely to include patients being transported by ambulance, or taken to a hospital emergency department, or hospitalized after knee replacement surgery or other surgical or other stressful medical procedures. [0003] Early detect...
