AI Article Synopsis
- Transcutaneous measurement of carbon dioxide was successfully performed at the infraclavicular site using a new digital sensor, as an alternative to the earlobe, especially beneficial for patients requiring non-invasive ventilation.
- A study comparing transcutaneous (P(c)CO(2)) and arterial (P(a)CO(2)) carbon dioxide levels in 50 samples showed a minimal bias and solid correlation between the two methods, indicating that the new site is reliable.
- The results support further research for expanding the clinical application of transcutaneous carbon dioxide monitoring at this infraclavicular location.
Article Abstract
Background: Transcutaneous measurement of carbon dioxide is routinely done at the earlobe site. In patients receiving non invasive ventilation or in the intensive care setting with necklines, an alternate measurement site would be useful. We started to use the infraclavicular site for transcutaneous measurements of carbon dioxide using a new digital sensor.
Aim: Comparison of transcutaneous carbon dioxide with arterial carbon dioxide at the infraclavicular site.
Methods: We retrospectively compared transcutaneous carbon dioxide at the infraclavicular site with arterial carbon dioxide in 50 samples. The Sentec Digital Monitoring System (Sentec AG, Therwil, Switzerland) was used. The V-Sign digital sensor was placed on the infraclavicular site at the medial two third and one third point from the sternoclavicular joint and acromioclavicular joint.
Results: When comparing P(c)CO(2) with P(a)CO(2) values, the Bland-Altman analysis revealed a bias of 0.02 kPa (95% CI: [- 0.1; 0.14]) with a precision of 0.42 kPa. Linear regression analysis describes the relationship between the two methods. The slope of the linear model was 0.85 ± 0.04 and the intercept was 0.77 ± 0.21 (RSE = 0.37, R(2) = 0.91).
Conclusion: The measurement of transcutaneous carbon dioxide at the infraclavicular site is feasible with a digital sensor and has a good correlation with the carbon dioxide values obtained from the arterial blood gas. The findings of the current study form the basis for further clinical studies for its regular application in clinical use.

Unlabelled: Infants requiring interhospital transfer for a higher level of care in the neonatal period are at increased risk of adverse outcomes. Optimising respiratory management is an important priority. The aim of this survey was to investigate current respiratory support strategies in neonatal transport and identify opportunities for the optimisation of clinical care and future research.

Electrochemical reduction of carbon dioxide (CO) into sustainable fuels and base chemicals requires precise control over and understanding of activity, selectivity and stability descriptors of the electrocatalyst under operation. Identification of the active phase under working conditions, but also deactivation factors after prolonged operation, are of the utmost importance to further improve electrocatalysts for electrochemical CO conversion. Here, we present a multiscale in situ investigation of activation and deactivation pathways of oxide-derived copper electrocatalysts under CO reduction conditions.

Prussian blue analogs (PBAs), as a classical kind of microporous materials, have attracted substantial interests considering their well-defined framework structures, unique physicochemical properties and low cost. However, PBAs typically adopt cubic structure that features small pore size and low specific surface area, which greatly limits their practical applications in various fields ranging from gas adsorption/separation to energy conversion/storage and biomedical treatments. Here we report the facile and general synthesis of unconventional hexagonal open PBA structures.

Cardiorespiratory signals have long been treated as "noise" in functional magnetic resonance imaging (fMRI) research, with the goal of minimizing their impact to isolate neural activity. However, there is a growing recognition that these signals, once seen as confounding variables, provide valuable insights into brain function and overall health. This shift reflects the dynamic interaction between the cardiovascular, respiratory, and neural systems, which together support brain activity.

The coupling of carbon dioxide (CO) with epoxides to produce cyclic carbonates is a desirable decarbonization approach, but its commercial applicability is still restricted by the costly catalysts required, as well as the need for high temperature and high pressure. Herein, oxygen vacancy-rich defective tungsten oxide (WO) rich in Lewis acid sites was modified by Prussian blue (PB), and the obtained composite reaches up to 94 % styrene carbonate yield (171 mmol gh) at ambient temperature and pressure, exhibiting outstanding advantages in the photocatalytic CO cycloaddition reaction compared with currently reported photocatalysts. It is found that the introduction of PB with photothermal properties significantly enhances the capability of WO to absorb and activate CO and epoxide, along with its light utilization ability.
