pulse oximetry reading and arterial blood gases.

Explanation:

Since pneumonia is associated with reduce levels of oxygen in the blood, meaning oxygen breathed in doesn't get to the lungs due to the blockage of airspace with mucus.

It is important to know the oxygen saturation of the patient (pulse oximetry) and know the oxygen and carbondioxide level in the blood, blood pH and lung functio ( arterial blood gases).

you may having too much sleep.. a good night sleep consists of about 7 hours. more than that could be the reason you're still tired throughout the day.
