A patient monitoring device () employing an ECG monitor () and a controller (). In operation, the ECG monitor () monitors a corrupted ECG waveform (), and the controller () classifies the corrupted ECG waveform () as one of a non-shockable rhythm or a potentially shockable rhythm. The corrupted ECG waveform () is classified by the controller () as the non-shockable rhythm responsive to a detection by the controller () of a presence of an asystole rhythm within the corrupted ECG waveform (). Conversely, the corrupted ECG waveform () is classified by the controller () as the potentially shockable rhythm responsive to a detection by the controller () of an absence of the asystole rhythm within the corrupted ECG waveform () or an indetermination by the controller () as to the presence of the asystole rhythm within the corrupted ECG waveform ().

A traumatic brain injury ('TBI') guideline system employing a patient monitoring sensor () and a patient monitoring device (). In operation, the patient monitoring sensor () generates data for monitoring a TBI parameter of a patient (e.g., systolic blood pressure, blood oxygen saturation or carbon dioxide expiration of the patient), and the patient monitoring device () generates a TBI indicator derived from a comparison of the TBI parameter data to parameter guideline data associated with a potential TBI of the patient. The patient monitoring device () may include a patient data monitor module () to monitor the TBI parameter data, and a TBI monitor module () to generate the TBI indicator. The TBI indicator is informative of a TBI status of the patient (e.g., a hypotension status, a hypoxia status or a ventilation status of the patient), and/or a TBI treatment for the patient (e.g., a ventilation treatment for the patient).

An ECG controller for an ECG device is connectable to a base ECG lead system (e.g., a 12-lead system) whereby the ECG controller implements an ECG waveform morphology based and ECG lead redundancy based detection and classification of any cable interchange (e.g., a limb cable interchange or a precordial cable interchange) between the ECG controller and the base ECG lead system. Alternatively, the ECG controller is further connectable to a sub-base ECG lead system (e.g., a limb only-lead system or a limited precordial-lead system) whereby the ECG controller implements an ECG waveform morphology based detection and classification of any cable interchange (e.g., a limb cable interchange or a precordial cable interchange) between the electrode interface and the sub-base ECG lead system.

Automatic detection/classification of ECG cable interchange for different ECG lead systems

When detecting ischemia and/or myocardial infarction in a subject, electrocardiogram (ECG) segments are analyzed for elevated ST segments indicative of ischemia and/or infarction. To mitigate false positive alerts, an ECG segment comprising an elevated ST segment that triggers an alert is presented to a clinician for verification as being indicative of ischemia or infarction, or as being attributable to a confounding condition not indicative of ischemia or infarction. Clinician feedback is used to adjust an elevated ST segment detection algorithm to improve accuracy and mitigate false positive alerts.

Immediately after airway placement and/or following any patient transfer, an automated program may be activated in a CO2 monitoring device to provide an airway device placement check. The automated program needs time to determine if the airway placement has been successful or not. During analysis of CO2 respiration data by the program, real-time feedback is displayed to the user as soon as the airway check program is activated until the time that a final decision on the success of airway placement is made. The real-time feedback displays one or more indicators of the progress of the program toward a determination of a successful or failed placement.
