Behavioral health professionals are at high risk for burnout and poor mental health. Our objective was to understand the impact of the Behavioral Health Providers Workforce Resiliency (BHPWR) ECHO Program on the resilience and burnout of participating behavioral health professionals. We assessed the first two years (March 2022 to March 2024) of the BHPWR ECHO, a national program operating from the University of New Mexico (N = 1585 attendees), using a mixed-methods design.

Article Synopsis
  • There is currently no universally accepted method for titrating positive end expiratory pressure (PEEP) in patients on spontaneous mechanical ventilation (SMV), despite some success with electrical impedance tomography (EIT) in controlled mechanical ventilation.
  • A new approach using regional peak flow (RPF) via EIT aims to evaluate lung mechanics specifically for SMV, which was not effectively addressed by existing algorithms.
  • In a study of 25 COVID-19 ARDS patients, EIT-guided PEEP titration showed feasibility and suggested that a cumulative collapse threshold of around 5% could provide the best balance of clinical and mechanical outcomes.

Background And Objective: Recruitment maneuvers with subsequent positive-end-expiratory-pressure (PEEP) have proven effective in recruiting lung volume and preventing alveoli collapse. However, determining a safe, effective, and patient-specific PEEP is not standardized, and this more optimal PEEP level evolves with patient condition, requiring personalised monitoring and care approaches to maintain optimal ventilation settings.

Methods: This research examines 3 physiologically relevant basis function sets (exponential, parabolic, cumulative) to enable better prediction of elastance evolution for a virtual patient or digital twin model of MV lung mechanics, including novel elements to model and predict distension elastance.

Purpose: To describe the effect of dexamethasone and tocilizumab on regional lung mechanics over admission in all mechanically ventilated COVID-19 patients.

Materials And Methods: Dynamic compliance, alveolar overdistension and collapse were serially determined using electric impedance tomography (EIT). Patients were categorized into three groups; no anti-inflammatory therapy, dexamethasone therapy, dexamethasone + tocilizumab therapy.

Electrical Impedance Tomography (EIT) is a non-invasive bedside imaging technique that provides real-time lung ventilation information on critically ill patients. EIT can potentially become a valuable tool for optimising mechanical ventilation, especially in patients with acute respiratory distress syndrome (ARDS). In addition, EIT has been shown to improve the understanding of ventilation distribution and lung aeration, which can help tailor ventilatory strategies according to patient needs.
