A 48-yeаr-оld femаle with а medical histоry оf hypertension arrives in the emergency department because of an acute onset of dyspnea. A rapid physical assessment reveals a pulse of 128 beats/min, respiratory rate 32 breaths/min and labored, and blood pressure 88/56 mm Hg. Bilateral coarse crackles are heard in the lung bases. Arterial blood gas results on a 15 L/min nonrebreather mask are: pH 7.35, PaCO2 45 mm Hg, PaO2 48 mm Hg, arterial SaO2 74%. The most appropriate immediate action for this patient is which of the following?
