Oxygen Manifesto, Part 1: Advice from 3 Respiratory Specialists
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 […]

Long COVID Outcomes at One Year After Mild SARS-CoV-2 Infection: Nationwide Cohort Study
This large cohort study evaluated the frequency of 70 long COVID outcomes in unvaccinated individuals with mild COVID infection matched to uninfected individuals and to vaccinated individuals. Anosmia and dysgeusia were the most frequently reported long COVID symptoms with the risk being dramatically increasing at 30 days to 6 months post infection and falling rapidly thereafter. Mild COVID generated an 85% increased risk of cognitive impairment an 80% increased risk of dyspnea and weakness and a nearly 50% increased risk for palpitations. The findings were consistent across all COVID variants and were more marked in adults than children. Vaccinated individuals with breakthrough infection had similar risk for all these outcomes with the exception of dyspnea, for which the risk was lower in vaccinated persons.
