Is it safe to use my albuterol inhaler throughout the day? (I am between insurance plans and can't afford preventative asthma meds.)

Albuterol. Only use albuterol inhaler if wheezing or chest tightness. If you are needing to use it throughout the day then you need to get seen. Doses used in hospitals are high and generally well tolerated BUT the fragility that your lungs are demonstrating is where the danger lies. Don't ignore your symptoms, get seen if you are using your inhaler "throughout the day" please. Be safe.
