Which type of patients may require a higher oxygen flow rate?

Patients with severe pulmonary conditions require a higher oxygen flow rate due to their compromised lung function and impaired oxygen exchange. Conditions such as chronic obstructive pulmonary disease (COPD), severe asthma, or advanced interstitial lung disease significantly affect a patient's ability to adequately oxygenate their blood. In such cases, the body struggles to maintain normal oxygen saturation levels, which can lead to hypoxemia.

As a result, these patients often need a higher flow of supplemental oxygen to achieve adequate oxygen saturation, typically aiming for levels above 90% or as prescribed by their healthcare provider. The increased flow rate helps overcome the limitations in their respiratory function, ensuring that their tissues receive sufficient oxygen. This approach is critical for managing their condition and improving their overall well-being.

In contrast, patients with chronic allergies, mild asthma, or those recovering from surgery may not require the same level of oxygen support, as their oxygenation may still be sufficient without significantly elevated flow rates.
