Practice of oxygen administration in patients hospitalized in internal medicine wards and intensive care units: A single-center prospective, observational study.
Observational study in Sao Paulo medical journal = Revista paulista de medicina, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundOxygen is widely used to treat hypoxemia.
objectiveTo determine the frequency of inappropriate oxygen administration in patients admitted to Internal Medicine (IM) wards and intensive care units (ICU). DESIGN AND
settingSingle-center prospective, observational study in a tertiary university hospital in Ankara, Türkiye.
methodsPatients who were hospitalized in the IM wards and ICU and were receiving oxygen were recruited. Every 6 hours, the oxygenation parameters were noted, and the averages over the first 24 hours of oxygen usage were recorded. Inappropriate usage was defined as oxygen flow rates > 6 L/min in the nasal cannula and < 5 L/min and > 10 L/min in the simple face mask, application of the simple face mask in chronic obstructive lung disease (COPD) exacerbation, SpO2 > 98% in general, or SpO2 > 92% in COPD exacerbation.
resultsOf the 397 patients, 20% in the IM wards and 50% of 124 in the ICU received oxygen. The oxygen method used was nasal cannula in 51%, simple face mask in 21%, and high-flow nasal cannula in 4% of the patients. Among the simple face mask applications, 46% were < 5 L/min and 5% were > 10 L/min. Among the 62% of patients with COPD exacerbations, the SpO2 was > 92%.
conclusionThe frequency of oxygen use was 20% among patients hospitalized in IM wards and 50% among patients in the ICU. Almost half of the simple face mask applications were inappropriate.
