Could forced drinking cause noncardiogenic pulmonary edema in elderlies?

"Forced drinking" ...of what? Forced anything is probably bad, but forced drinking can cause many problems. If you force someone to drink too much water the biggest risk is of hyponatremia (low serum sodium, with ill effects on the brain mostly) , not pulmonary edema. Forced drinking of alcohol is also referred to as assault in my view, and should be reported to the police.
No one should be . Forced to take liquids. If a patient is being assisted with oral intake, care should be taken that the right amounts are being administered fluid overload can cause CHF and pulmonary edema.
