Effect of vertical distance between the heart base and the cuff on arterial blood pressure measurements using PetMAP in anaesthetised dogs

Journal of Small Animal Practice, EarlyView.
Objectives To evaluate how variations in limb positioning, when compared with standard position at the heart base, affect oscillometric arterial blood pressure measurements in 22 anaesthetised healthy dogs. Materials and Methods The thoracic vertical depth was measured in each dog from the caudal angle of the scapula to the body of the sternum caudal ...

Climate benefits of wetland restoration are constrained by slow vegetation recovery

Restoration Ecology, EarlyView.
Abstract Introduction Wetland restoration is widely used to enhance ecosystem resilience, biodiversity, and climate mitigation. However, restoring hydrology may not lead to rapid vegetation establishment or reduced greenhouse gas (GHG) emissions in severely degraded wetlands.

Comparison of end-tidal carbon dioxide and point-of-care echocardiography for fluid response at the bedside

, 2019
Purpose: In this study, we aimed to compare cardiac output, echocardiographic pulmonary velocity-time integral, and end-tidal carbon dioxide values before and after the passive leg raising maneuver in healthy volunteers.

Comparison of Norepinephrine with Dopamine Infusion on the End-Tidal Carbon Dioxide (ETco2) Pressure in Patients with Septic Shock

Caspian Journal of Internal Medicine, 2021
Background: Septic shock is a critical medical condition and immediate intervention is required as well as hemodynamic stability using fluid and vasopressor. Direct relationship between changes in ETco2 and changes in the cardiac output. We evaluated the

End-tidal carbon dioxide tension reflects arterial carbon dioxide tension in the heat-stressed human with and without simulated hemorrhage

, 2011
End-tidal carbon dioxide tension (PetCO2) is reduced during an orthostatic challenge, during heat stress, and during a combination of these two conditions.

Embodied ethnographies: Entanglements in the Anthropocene

The Australian Journal of Anthropology, EarlyView.
Abstract ‘Entanglements in the Anthropocene’ is an embodied exploration of the intersections of place, dance and lens‐based practices (photography and video). Lens‐based works discussed here result from collaborative research projects and grow from a shared curiosity about aesthetics in the Anthropocene and how to express entangled relationships with ...

Metabolic effects of carbon dioxide insufflation during laparoscopic surgery: Changes in pH, arterial partial pressure of carbon dioxide (PaCO2) and end tidal carbon dioxide (EtCO2).

, 2019
Purpose: The purpose of this study was to assess the effects of low tidal volume ventilation on patients undergoing laparoscopic surgery on partial pressure of carbon dioxide, arterial to end tidal carbon dioxide gradient and acid base excess. Methods:

Individuals with persisting post‐concussion symptoms with physiological subtype demonstrate altered cardiovascular and autonomic responses to face cooling

Experimental Physiology, EarlyView.
Abstract Individuals with persisting post‐concussion symptoms with physiological subtype (PPCS‐P) demonstrate exercise intolerance due to exacerbation of concussion‐like symptoms during incremental exercise. We tested the hypothesis that individuals with PPCS‐P (n = 12) would have a blunted cardiac autonomic response to face cooling compared to healthy

Optimizing cerebrovascular endothelial health through shear stress modulation

Experimental Physiology, EarlyView.
Abstract The endothelium plays a pivotal role in regulating cerebrovascular blood flow, and its dysfunction increases the risk of cerebrovascular disease. Endothelial shear stress, a primary mechanical stimulus for endothelial nitric oxide production, is a key modulator of vascular adaptation.
