Rationale: The primary action of short-acting beta2-agonists (SABAs) is to relieve bronchospasm.

By relieving bronchospasm, SABAs help improve airflow and alleviate symptoms of asthma such as wheezing and shortness of breath.

Morphine helps in reducing preload and afterload, which ultimately improves oxygenation to the heart muscle. By decreasing the workload on the heart, morphine can alleviate symptoms and decrease the strain on the heart muscle during an MI.
