A tool that predicts the lifespan of a portable oxygen supply uses factors such as tank size, flow rate, and patient oxygen requirements. For example, a user might input a 2-liter tank at a 2 liters-per-minute flow rate to determine how long the tank will last. These tools often provide estimations for both continuous flow and pulse dose delivery systems.
Accurate estimations of oxygen supply duration are critical for patient safety and care planning. This knowledge allows patients to manage their oxygen needs effectively, ensuring they have enough oxygen for activities of daily living, travel, and emergencies. Historically, healthcare professionals relied on manual calculations and experience, but digital tools now offer greater speed and precision, reducing the risk of miscalculations. These tools empower patients to take a more active role in their respiratory care.
