Filter by:A prospective descriptive study of the use of an individualized capnography to each lung in the context of one-lung ventilation achieved with a double-lumen tube. - Pilot project and proof of concept Brief Summary: - One study suggests a way to predict possible events of hypoxemia (Sat O2 < 90%) during one lung ventilation (OLV) with the use of two individualized capnography devices on each lung during two-lung ventilation before inducing OLV. - In addition, a recent presentation in the 2021 Thoracic Anesthesia Symposium suggested possible benefits of the use of a capnography device on the non-ventilated lung in the detection of air leaks around the bronchial cuff. - The same presentation demonstrated the utility of EtCo2 measurement to determine the achievement of complete lung collapse. With these previous demonstrations, the use of an individualized capnography for each lung can potentially describe different steps during thoracic surgery. Therefore, a descriptive prospective study on patients that require thoracic surgery with use of a double lumen tube is proposed to verify the feasibility of dual capnography during OLV. The use of two different devices, randomized during our study, will also help to identify the impact of different air aspiration levels on our measures. Such results will allow to put forward prospective projects to help to optimize OLV during thoracic surgeries.
After endotracheal intubation verifying the location of endotracheal tube is of utmost importance. Many methods have been applied but none is perfect. The standard practice in the investigator's center has been to use auscultation of chest with capnography. Ultrasound machines are now gaining popularity and their access extends from operation theatres, emergency rooms and even many primary health centres. Both capnography and ultrasonography are safe. This study found out that Ultrasonography and waveform capnography are both reliable methods of confirming endotracheal tube position. The use of ultrasound could help reduce time and increase precision of confirming endotracheal tube position. Ultrasound can confirm endotracheal tube position before manual bag ventilations, and thus may prevent aspiration of gastric contents into patient's lungs.
This study evaluates the performance of eight (8) cleared capnography carbon dioxide (CO2) sampling filterlines during patient simulated scripted activities when connected to a Medtronic (MDT) dual parameter monitor.
There is few information about the best capnometry value in recovery room for intubated awakening patients. Furthermore, capnometry values could influence ventilation applied by nurses on these patients. The aim of this study is to observe the effects of capnometry monitoring on intubated awakening patients in recovery room.
Many post-operative complications arise from patients who breathe inadequately. Inadequate respiration, whether the result of surgery or the anesthesia, causes a decrease in blood oxygen saturation and an increase in carbon dioxide partial pressure. Both of these surrogate measurements of respiration may pose a challenge to measure. Some administer exogenous oxygen to all patients as they leave the operating room in order to maintain the blood oxygen saturation. This renders the oximeter a less sensitive metric of depressed respiration. In the face of decreased respiration, the carbon dioxide levels continue to increase slowly and often go undetected unless blood gases are measured. Indeed carbon dioxide blood levels are the only metric to detect inadequate ventilation using this surrogate index. Monitoring ventilation is a serious challenge outside of critical care settings. In fact, there are no monitors available that can measure tidal volume or relative tidal volume outside of these settings. Linshom is a novel instrument that tracks relative respiration by measuring the excursions of the temperature swings between inspiration and expiration and normalizing them to the patient's breathing. This monitor may be the first non-invasive monitor to measure relative tidal volume in non-critical care settings. The purpose of this study is to determine whether a non-invasive, temperature-based respiratory instrument can track tidal volume (Vt) in patients. The investigators hypothesize that the Linshom device can accurately and consistently track tidal volume as measured by closed loop mechanical ventilator.
This studies´ objective is to describe how different PEEP levels affect dead space measured by Bohr´s formula.
