Background: In patients with acute hypoxemic respiratory failure (AHRF) under mechanical ventilation, the change in pressure slope during a low-flow insufflation indicates a global airway opening pressure (AOP) needed to reopen closed airways and may be used for titration of positive end-expiratory pressure.
Objectives: To understand 1) if airways open homogeneously inside the lungs or significant regional AOP variations exist; 2) whether the pattern of the pressure slope change during low-flow insufflation can indicate the presence of regional AOP variations.
Methods: Using electrical impedance tomography, we recorded low-flow insufflation maneuvers (< 10 L/min) starting from end-expiratory positive pressure 0-5 cmHO.
Background: Predicting complete liberation from mechanical ventilation (MV) is still challenging. Electrical impedance tomography (EIT) offers a non-invasive measure of regional ventilation distribution and could bring additional information.
Research Question: Whether the display of regional ventilation distribution during a Spontaneous Breathing Trial (SBT) could help at predicting early and successful liberation from MV.
Purpose Of Review: Past observational studies have reported the association between patient-ventilator asynchronies and poor clinical outcomes, namely longer duration of mechanical ventilation and higher mortality. But causality has remained undetermined. During the era of lung and diaphragm protective ventilation, should we revolutionize our clinical practice to detect and treat dyssynchrony?
Recent Findings: Clinicians' ability to recognize asynchronies is typically low.
Background: As Mohs micrographic surgery becomes more widely used in immunosuppressed patients, it is important to understand the risks in this unique population.
Objective: To determine whether immunosuppressed patients are at an increased risk for surgical site infection and evaluate the utility of postoperative antibiotics for the prevention of surgical site infection.
Materials And Methods: A single-center retrospective review of patients who underwent Mohs micrographic surgery between October 9, 2014, and August 20, 2021, was performed.
