High PEEP Increases Airway Dead Space and Decreases Alveolar Ventilation: A New Technique for Volumetric Capnography [PDF]

Biomedicines
Background/Objectives: Identifying the optimal positive end-expiratory pressure (PEEP) is a major challenge in implementing strategies to prevent ventilator-induced lung injury in newborns.

Объемная капнография: возможности применения в пульмонологической практике [PDF]

PULMONOLOGIYA, 2017
The aim of this review was to analyze abilities of a novel diagnostic method intended to measure the lung function. Volumetric capnography is one of the most promising tools for assessing pulmonary function.

Relationships between capnogram parameters by mainstream and sidestream techniques at different breathing frequencies [PDF]

Scientific Reports
Capnography, routinely used in operating rooms and intensive care units, reveals essential information on lung ventilation and ventilation–perfusion matching. Mainstream capnography directly measures CO2 in the breathing circuit for accurate analysis and

Single-FiO₂ lung modelling with machine learning: a computer simulation incorporating volumetric capnography. [PDF]

J Clin Monit Comput, 2023
We investigated whether machine learning (ML) analysis of ICU monitoring data incorporating volumetric capnography measurements of mean alveolar PCO2 can partition venous admixture (VenAd) into its shunt and low V/Q components without manipulating the ...

Use of carbon dioxide production to detect bacterial superinfections in mechanically ventilated patients with acute respiratory distress syndrome: an exploratory prospective cohort study [PDF]

BMJ Open Respiratory Research
Background Bacterial superinfections are common in patients with acute respiratory distress syndrome (ARDS) but diagnosing them is challenging. Exhaled carbon dioxide (V’CO2) may be increased during bacterial infection, suggesting a potential marker for ...

Correlation between parameters of volumetric capnography and spirometry during a submaximal exercise protocol on a treadmill in patients with cystic fibrosis and healthy controls

Pulmonology, 2019
Introduction: Spirometry is the most frequently used test to evaluate the progression of lung damage in cystic fibrosis (CF). However, there has been low sensitivity in detecting early lung changes.
