The need for point of care, fast reliable, and high IQ imaging is growing as technology shifts from analog/ Cr cassettes to wireless flat panel. These units are used for radiographic imaging of patients who are in areas, such as intensive and critical care units or operating and emergency rooms, such that standard fixed radiographic equipment are not able to use. These medical applications can include general radiography, orthopedic, pediatric, skeletal, and abdominal.

These falsely issued alarms disrupt patients’ rest, drain hospital resources, and desensitize the hospital staff to potential emergency situations, which is named as false alarm fatigue. It has been estimated that 43% of life threatening electrocardiogram (ECG) alarms issued by bedside monitors are false, with some categories of alarms being as high as 90%. Ventricular-fibrillation/flutter is the most commonly identified arrhythmia in cardiac arrest patients and it usually ends in death within minutes unless an urgent treatment is not applied. Therefore, in our study, we consider the alarms triggered by ventricular-flutter/fibrillation condition. This type of alarm is usually triggered by ECG and pulsatile waveforms recorded by monitoring equipments, which have standard alarm triggering criteria such as instantaneous thresholds on the predictor values. Most of the ventricular-fibrillation/flutter false alarms are caused by single channel artifacts. In this study, we aim to fuse ECG features with information from other independent signals and get more robust alarm algorithms for ICUs. Pulsatile waveforms, which are highly correlated signals, can be used to corroborate the alarm category and to suppress significant number of false ECG alarms in ICUs. Photoplethysmogram (PPG), arterial blood pressure (ABP) or both PPG and ABP can be used for this purpose. These waveforms are the least noisy pressure signals available in certain ICUs and rarely contain ECG-related artifacts. We implement four different algorithms that use information from ECG, PPG and ABP waveforms, and compare the results. Our best result is 100%/98.1% in terms of sensitivity/specificity based on the Cinc2015 Challenge training dataset.

It has been estimated that 43% of life threatening electrocardiogram (ECG) alarms issued by bedside monitors are false, with some categories of alarm being as high as 90%. In our study, we consider the alarms triggered by four life threatening conditions. These alarms are usually triggered by ECG and pulsatile waveforms recorded by monitoring equipment, which have standard alarm triggering criteria such as instantaneous thresholds on the predictor values.

Patient monitors are one of these candidates in this scope. They includes high technology sensors and signal processing algorithms for early diagnostic and any emergent case on patients reacting as alarms. These properties are very important especially in intensive care units (ICU). However, these devices are only available in intensive care unit departments and not mobile. A remote mobile health monitoring system which is implementable to mobile phone and web service capabilities is proposed in this paper. It provides an early alarm solution; specifically, continuous monitoring of physiological conditions, implementable to send warning messages services during an urgent event. There are around 7 million deaths because of heart failure. In this study, the developed method, which based on PPG signals, experimental results on CinC2015 database show...
