The other side?: Give oxygen, fluid, antibiotics. I wasn't aware of this as a key management of pneumonia (ensuring this is the diagnosis, excluding PE, sepsis, CCF etc), but I guess its worth trying them on the other side, and perhaps on their back ... oxygenation is a product of airflow and blood supply ... perhaps lying on that side reduces perfusion of the lungs and so reduces oxygenation?

Mgt: Positioning is important since there is a gradient of dependent blood flow. The diseased lung has presumably less ventilation and any increase in blood flow to the affected lung can impact the oxygenation in the systemic circulation.
