The bronchodilating drug was given to treat asthma, which is a respiratory condition that affects the airways and the ability to breathe properly. The ventilation portion of the V/Q ratio refers to the amount of air that reaches the alveoli in the lungs and participates in gas exchange. In asthma, the airways can become narrowed and obstructed, reducing the amount of air that can reach the alveoli. This results in a decrease in oxygen saturation, as seen by the patient's initial SpO₂ measurement of 89%. The bronchodilating drug helps to open up the airways, allowing more air to reach the alveoli and improving ventilation, which can increase SpO₂ levels. Therefore, the patient's problem most likely originated in the ventilation portion of the V/Q ratio.
