Article Synopsis
- - This study examined the EzPAP Positive Airway Pressure System, a noninvasive device designed to help expand the lungs and improve gas exchange, particularly among spontaneously breathing patients with and without tracheostomy.
- - Conducted at a university hospital, the study found that while gas exchange did not significantly change in most patients after PEP, those with tracheostomy showed temporary improvement immediately after treatment, although it did not hold after two hours.
- - Ultimately, the study concluded that while lung expansion improved radiological scores within a week, the PEP therapy did not significantly alleviate respiratory distress in the subjects.
Background: This study analyzed weaning characteristics and assessed the association of clinical and ultrasonographic indices-maximum inspiratory pressure (MIP), rapid shallow breathing index (RSBI), peak flow expiratory (PFE), diaphragm-thickening fraction (DTF), diaphragm thickness (DT), diaphragm excursion (DE), diaphragm-RSBI (D-RSBI), and lung ultrasound (LUS) patterns-with weaning failure.
Methods: This retrospective cohort study included critically ill COVID-19 patients aged 18 and older who had been on invasive mechanical ventilation for at least 48 h and undergoing weaning. Exclusion criteria included absence of ultrasound assessments, neuromuscular diseases, and chronic cardio-respiratory dysfunction.
Respiratory physiotherapy, including the management of invasive mechanical ventilation (MV) and noninvasive mechanical ventilation (NIV), is a key supportive intervention for critically ill patients. MV has potential for inducing ventilator-induced lung injury (VILI) as well as long-term complications related to prolonged bed rest, such as post-intensive care syndrome and intensive care unit acquired weakness. Physical and respiratory therapy, developed by the critical care team, in a timely manner, has been shown to prevent these complications.

We estimate a bivariate ordered probit model that allows us to account for a potential correlation between these types of preferences. The data reveals that while 71% of respondents take a reusable bag for shopping, only 58% of the sample state to strongly agree with prohibiting plastic bags.
