Is increased pulmonary arterial flow velocity serious?

Pulmonary artery flow velocity increase usually has no impact on the body if symptoms are mild. However, if the condition is severe, surgical treatment under a doctor's guidance is generally required. Specific analysis is as follows:

1. Mild cases

The majority of pulmonary artery flow velocity increases are due to physiological reasons. Normally, peak pulmonary valve flow velocity in adults ranges from 60 to 90 cm/s, and in children from 50 to 80 cm/s. In mild pediatric cases, conservative treatment may be initially considered. Under medical supervision, non-steroidal anti-inflammatory drugs (NSAIDs) can also be used to relieve symptoms. Slight increases in pulmonary artery flow velocity in adults typically do not require treatment; therefore, this is considered not serious.

2. Severe cases

If the flow velocity is significantly increased and causes symptoms of pulmonary valve stenosis, with velocities reaching 3–4 m/s across the pulmonary valve, the condition is relatively serious and may affect cardiac function. Timely examinations should be performed, and surgical intervention should be conducted under medical guidance to prevent worsening of the condition.

In addition, such symptoms could also result from a patent foramen ovale. A detailed evaluation is recommended to determine the exact underlying cause, followed by appropriate treatment in coordination with a physician. It is also important to ensure adequate sleep and consume high-protein foods to enhance immunity.
