Abstract:
Clinical monitoring and diagnostic systems may require the analysis of multiple physiologic signals to generate a diagnosis. The complexity of these systems is formidable for at least two reasons: clinical physiologic signals are noisy, and systems built around multiple signals may fail when any single signal is absent. In view of these limitations, we have been developing a clinical respiratory CO2 waveform (capnogram) diagnostic system. The purpose of this system is to develop a differential diagnosis from a single signal for subsequent evaluation within the context of multiple single-signals. This paper will review the development issues which we have been confronting, and discuss the tools and methods which have been successful.

Assessment of Ventilation I: Respiratory Rate
A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.
Critical Guidelines for Assessing Ventilation:
Acute Respiratory Failure-III
Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
