Figure 1:
CO2 level of apheresis platelets. Measurements of CO2 that accumulates above bacterially contaminated apheresis platelets were performed using a laser instrument. Expired apheresis platelets (6 days old) were examined before and after contamination with Staphylococcus epidermidis (t=0). CO2 concentration rose rapidly beginning one hour after inoculation (at a bacterial concentration of 3*106 CFU/mL).
