The detection of chemical compounds in exhaled human breath presents an opportunity to
determine physiological state, diagnose disease or assess environmental exposure. Recent …

Background Capnography has many uses in the emergency department (ED) and critical
care setting, most commonly cardiac arrest and procedural sedation. Objective of the …

Anesthesiologists historically have appeared to be the forerunners in the implementation of
tools and standards for safety in the medical profession. Since 1985, there has been a …

Introduction Prolonged ventilation and failed extubation are associated with increased harm
and cost. The added value of heart and respiratory rate variability (HRV and RRV) during …

Wide fluctuations in partial pressure of carbon dioxide (PaCO2) can potentially be
associated with neurological and lung injury in neonates. Blood gas measurement is the …

The presence of an elevated amount of methane (CH4) in exhaled breath can be used as a
non-invasive tool to monitor certain health conditions. A compact, inexpensive and …

Induction of general anesthesia significantly impairs control of the respiratory system,
particularly upper-airway maintenance mechanisms. To ensure patient safety …

STUDY OBJECTIVE: To determine if the slope of Phase II and Phase III, and the alpha angle
of the expiratory capnographic waveform, as measured via computer-recognizable …

IMPLICATIONS: Capnogram shape was used to separate obstructive lung disease subjects
from normals and subjects with restrictive lung disease. Changes in the capnogram shape …

Quantitative features derived from the time-based and volumetric capnogram such as
respiratory rate, end-tidal PCO 2, dead space, carbon dioxide production, and qualitative …
