Uncover vital insights about supplemental oxygen use, demystify misconceptions, and learn best practices for managing respiratory diseases. Good day, physicians. Let’s talk about the controversial issue of supplemental oxygen use, frequently discussed by patients, clinicians, advocacy groups, and even politicians. In this summary, we’ll untangle misconceptions and illuminate best practices. To start with, the body’s oxygen utilization depends on three things: lung function, heart efficiency, and muscle oxygen use. These factors can improve with exercise, but worsen with inactivity. Remember, exercise matters. Why does oxygen matter? For patients with chronic obstructive pulmonary disease (COPD), pulmonary fibrosis (PF), or pulmonary hypertension (PH), impaired oxygenation can lead to hypoxemia and hypoxia. Hence, supplemental oxygen becomes a necessity. How do we assess oxygen levels? Two tests can be employed: arterial blood gas (ABG) or pulse oximetry. Normal partial pressure of oxygen, as per ABG, is around 75-100 mmHg, and a drop below 60 necessitates supplemental oxygen. Oxygen saturation, measurable via either test, should ideally be 95% or above, and values dropping to 90 or below indicate the need for supplemental oxygen. Now, let’s dispel some myths. Shortness of breath doesn’t always equate to hypoxia. A patient can experience breathlessness even with normal oxygen […]

In a recent single-center prospective cohort study, the effect of unsuccessful treatment of ventilator-associated pneumonia (VAP) on mortality rates in patients with severe pneumonia was evaluated. The study involved 585 mechanically ventilated patients with severe pneumonia and respiratory failure, including 190 with severe COVID-19, all of whom underwent at least one bronchoalveolar lavage. A novel machine learning approach, CarpeDiem, was employed to group similar ICU patient-days into clinical states based on electronic health record data. Findings indicated that the lengthy ICU stays experienced by COVID-19 patients were largely due to prolonged periods of respiratory failure. The study discovered that although VAP wasn’t a contributing factor to mortality rates overall, patients with a single episode of unsuccessfully treated VAP demonstrated a significantly higher mortality rate (76.4%) compared to those with successfully treated VAP (17.6%). Furthermore, the CarpeDiem model highlighted that unresolved VAP was linked with transitions to clinical states associated with increased mortality. The study underscores that unsuccessful treatment of VAP is correlated with higher mortality and that patients with COVID-19 are at an elevated risk of VAP due to prolonged respiratory failure.
