Sterilization Process
Why do most steam sterilizers sense and record chamber temperature in the drain line?
- AIt is the hottest spot, so the reading gives the peak temperature
- BIt is usually the coolest spot, where air and condensate collect
- CIt is the point where steam first enters the chamber during a cycle
- DIt is the easiest place for service staff to reach for calibration
Not A. Measuring at the hottest spot would hide cooler areas where sterilizing conditions might not be met.
B is right. Air and condensate flow down to the drain, so it is usually the coolest point in the chamber. Measuring there confirms whether even the least favorable spot has reached the required temperature.
