A 68-year-old male patient with a history of congestive heart failure (CHF) is admitted to the hospital with worsening dyspnea and peripheral edema. Laboratory tests reveal the following serum electrolyte imbalances: Sodium (Na⁺) = 130 mEq/L, Potassium (K⁺) = 5.5 mEq/L, and Chloride (Cl^-) = 95 mEq/L. The healthcare provider prescribes a diuretic to manage fluid overload.

Considering the patient's current electrolyte levels, fill in the blank with the appropriate value for the patient's Sodium intake recommendations. The patient's Sodium intake should not exceed _____ mEq/day to avoid exacerbating his condition.
