In patients with respiratory distress, which vital sign changes should be closely monitored?

In patients experiencing respiratory distress, monitoring SpO2 changes and heart rate is crucial because these parameters provide direct insights into the patient's respiratory function and overall hemodynamic status. The SpO2 level reflects the oxygen saturation of hemoglobin in the blood, which is vital for ensuring that the body's tissues receive adequate oxygen. In respiratory distress, a decrease in SpO2 indicates impaired gas exchange and potential hypoxemia, which necessitates urgent intervention to restore adequate oxygen levels.

Additionally, heart rate can be an important indicator of the body's response to hypoxemia and stress. An increased heart rate may suggest compensatory mechanisms in response to decreased oxygen levels or underlying anxiety and distress. Conversely, bradycardia can indicate severe metabolic disturbances or increased vagal tone related to respiratory issues. Thus, monitoring these two vital signs helps determine the severity of the respiratory condition and guides treatment decisions.

Temperature fluctuations, blood glucose levels, and urine output, while important in managing a patient's overall health, do not provide immediate or direct information about respiratory function in the context of respiratory distress.
