Ventilator waveforms are graphic representations of changes in pressure, flow, and volume within a ventilator circuit. The changes in these parameters over time may be displayed individually (scalars) or plotted one against another (pressure-volume and flow-volume loops).

Critical Care Nursing Clinics of North America, 1996
This article provides a description of correct balloon pump timing as well as the potential timing errors that can occur. There are many factors in addition to timing that can affect the altered arterial waveform during balloon pumping. When analyzing the waveform for appropriate timing, it is important to consider factors associated with the patient ...

Computer Methods and Programs in Biomedicine, 1990
We developed three analog logic SPICE (Simulation Program with Integrated Circuit Emphasis, developed at the University of California, Berkeley, CA) subcircuits, a voltage comparator and a nonlinear waveform generator to compliment the previously derived functions (Goldstein and Rypins, Comput. Methods Programs Biomed.

Best Practice & Research Clinical Anaesthesiology, 2014
The bedside measurement of continuous arterial pressure values from waveform analysis has been routinely available via indwelling arterial catheterization for >50 years. Invasive blood pressure monitoring has been utilized in critically ill patients, in both the operating room and critical care units, to facilitate rapid diagnoses of cardiovascular ...

Improved defibrillator waveform safety factor with biphasic waveforms
American Journal of Physiology-Heart and Circulatory Physiology, 1983Excitation thresholds and arrhythmias were studied in "adult-type" cultured chick embryo myocardial cells after electric field stimulation with biphasic, truncated, and rectified underdamped RLC (resistance-inductance-capacitance) type waveforms, to test the hypothesis that the negative phase of biphasic waveforms ameliorates membrane dysfunction ...

2016 IEEE 12th International Colloquium on Signal Processing & Its Applications (CSPA), 2016
We propose a method of extracting current waveforms of appliances from the current waveform, which is a mixture of their current waveforms and unidentified current waveforms. The purpose of the method is for monitoring the load of individual appliances by analyzing the current waveform on a power distribution board.

Hierarchical Representation of Waveforms
IEEE Transactions on Pattern Analysis and Machine Intelligence, 1979Ehrich and Foith have proposed an approach to the hierarchical representation of waveforms based on peak dominance relations. This correspondence proposes an alternative approach, derived from concepts of fuzzy connectedness. It also discusses the possibility of extending this approach to the description of curves and of images.

Frequency Coded Waveforms for Adaptive Waveform Radar
2006 40th Annual Conference on Information Sciences and Systems, 2006We consider the use of frequency coded sequences for adaptive waveform radar. In particular, we investigate the joint use of stepped frequency chirps, Costas sequences, and pushing sequences to form an effective signal set for adaptive waveform radar.

Waveform synthesis for transmission of complex waveforms
RAWCON 99. 1999 IEEE Radio and Wireless Conference (Cat. No.99EX292), 2003A new transmit architecture for digital radios is proposed that emphasizes the use of pre-computed waveforms stored in memory instead of real-time computation. We present results that show how direct synthesis techniques can be extended to directly generate many types of digitally modulated waveforms such as PSK or QAM.
