What action should be taken if a patient is in the asthma red zone?

When a patient is in the asthma red zone, it indicates that they are experiencing severe symptoms that could potentially lead to a life-threatening situation. This is characterized by significant difficulty breathing, wheezing, chest tightness, or decreased peak flow readings that are significantly below their personal best.

In such cases, if symptoms do not improve or worsen despite using a rescue inhaler (typically a short-acting bronchodilator), it is crucial to seek immediate medical assistance. Calling 911 ensures that the patient can receive timely intervention, which may include advanced treatments that can stabilize their condition.

This action is vital because delays in treatment during a severe asthma attack can lead to respiratory failure or severe complications. Therefore, the correct response emphasizes the importance of prompt action in critical situations to ensure the patient's safety and well-being.

Other options, such as adjusting doses or modifying medications without professional guidance, may not provide the immediate help required in an emergency, making it essential to prioritize contacting emergency services if there is no improvement.
