Oxygen Saturation in Relation to Flying Altitude. A Scoping Review Protocol.
Article in Acta anaesthesiologica Scandinavica, 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
backgroundDuring air travel, the decrease in air pressure leads to a decrease in oxygen partial pressure causing oxygen desaturation. Every year, several commercial aircraft need to divert and perform unscheduled landings due to hypoxic symptoms or medical emergencies. How individuals are affected depends on their physical and medical conditions, as well as the cabin pressure of the aircraft. The phenomenon is of particular concern for individuals with pre-existing medical conditions, as it may lead to hypoxic symptoms and necessitate unscheduled landings in some cases. The investigators aim to investigate the existing literature to explore how the impact of reduced oxygen partial pressure affects the oxygen saturation as a result of a decrease in cabin pressure due to aircraft altitude, and to assess the frequency of hypoxic symptoms reported during air travel. The purpose of the scoping review is to investigate the relationship between altitude, cabin pressure, and patient oxygenation during air travel. Further, the investigators will report the frequency of the reporting of hypoxic symptoms in the studies conducted. METHODS AND ANALYSIS: This scoping review will be conducted in accordance with the Cochrane Handbook and Joanna Briggs Institute Manual for Scoping Reviews. The review question will be formulated using the Population, Intervention, Comparator, Outcome, Study Design, Timeframe (PICOST) framework. Every study design is eligible, apart from reviews, meta-analyses, comments/letters without original data, case reports with less than five cases, animal studies, and in vitro studies. The investigators will include all articles in English or Scandinavian. The investigators will base their conclusions on the findings of the review. ETHICS AND DISSEMINATION: According to Danish law, scoping reviews are exempt from ethics committee approval. The investigators will publish results from the scoping review in a peer-reviewed journal and present the results at scientific conferences.
