Which supportive measure should be taken during a suspected airway obstruction?

Positioning the patient upright and administering oxygen if possible is a crucial supportive measure during a suspected airway obstruction. When a person is experiencing an obstruction, whether it is partial or complete, positioning plays a significant role in facilitating airflow and helping to relieve distress. An upright position can help expand the thoracic cavity, making it easier for the patient to breathe.

Administering oxygen is also vital in this situation since it can help improve oxygenation, especially if the airway is compromised. Providing supplemental oxygen while maintaining an appropriate position can help alleviate hypoxemia and maintain adequate oxygen levels in the blood until the obstruction is resolved.

Other supportive measures like administering IV fluids or using sedatives are not appropriate during an airway obstruction. Fluids may not directly address the airway problem, and sedatives could depress the respiratory system further, worsening the situation. Performing chest compressions is typically reserved for cardiac arrest scenarios and would not be the first-line response in managing an airway obstruction. Thus, the focus should always be on positioning the patient for optimal airflow and supporting their breathing with oxygen when needed.
