COPD patients' pre-flight check: A narrative review.

Area of Science:

• Pulmonary Medicine
• Aerospace Medicine

Background:

• Air travel presents unique challenges for individuals with chronic obstructive pulmonary disease (COPD).
• Assessing fitness to fly for COPD patients requires updated guidelines.

Purpose of the Study:

• To review and update the requirements for air travel allowance in people with COPD without chronic respiratory failure.
• To provide guidance on managing in-flight oxygenation challenges.

Main Methods:

• A comprehensive literature review was conducted on PubMed, Scopus, and Ovid (2000-2021).
• Key search terms included COPD, air-travel, in-flight hypoxemia, and fitness to air travel.
• Official regulatory documents and guidelines were also analyzed.

Main Results:

• Current guidelines recommend supplemental oxygen if in-flight PaO2 is predicted to fall below 6.6 or 7.3 kPa.
• Lung function variables, prediction equations, and algorithms can estimate in-flight oxygen needs.
• Exercise-induced desaturation and aerobic capacity are significant predictors of in-flight PaO2.

Conclusions:

• COPD patients with recent exacerbations, medication changes, or high anticipated stress require thorough pre-flight medical evaluation.
• Hypoxia-altitude simulation tests can identify individuals needing further assessment.
• Careful physician evaluation is crucial for ensuring safe air travel for COPD patients.
