Ventilatory Failure

Ventilatory failure occurs when the lungs are unable to exchange air adequately, which makes it difficult for oxygen to enter or carbon dioxide to leave. It can set in suddenly or develop gradually.

Signs that may appear:

• A sensation of shortness of breath or rapid breathing
• Fatigue, drowsiness, or confusion
• A bluish color in the lips or nails

When is it urgent? Severe difficulty breathing requires immediate attention, since it can compromise vital functions and worsen in a short time.

Which specialist manages it? In acute situations the emergency physician steps in, while the pulmonologist, internist, or general practitioner follow up on the underlying causes, such as lung or kidney problems. If breathing is persistently affected or appears suddenly, seeking professional evaluation is the safest path.
