What action should be taken immediately upon recognizing respiratory distress in a patient?

Upon recognizing respiratory distress in a patient, the immediate priority is to assess the airway and provide support. This action is critical as it ensures that the patient's airway is patent, allowing for adequate ventilation and oxygenation. Recognizing respiratory distress can indicate potential airway obstruction or inadequate breathing, which could quickly lead to respiratory failure if not addressed.

Assessing the airway helps identify any obstructions, while providing support might include positioning the patient optimally or providing supplemental oxygen if needed. This foundational step is essential before any interventions such as bronchodilator administration or bag-mask ventilation, ensuring that the underlying issue with the airway is first dealt with effectively. In emergency situations, swift management of the airway is crucial for preventing more serious complications and maintaining the patient's overall safety.
