I wanted to see what you thought about this. I just finished reading Florence Nightengales "nursing notes" and one of the chapters in her book is on ventilation in the hospital. Miss Nightengales theory is that opening the window is very important to the healing of patients. "Fresh" air is better than circulating "sick" air. I of course believe this to be true, as fresh air is definitely important to our spirit and well being, etc. I noticed however, that all of the hospitals where I have done my clinical rotations, their windows don't open. I don't know what their argument for having windows that don't open is. Perhaps they think the air is well circulated within the hospital? Or maybe they think the patients will become sicker with fresh air or maybe catch pneumonia? I think all hospitals should allow windows to be opened. There is nothing better than "fresh" air, IMO.
