During surgery, how does the anaesthesiologist monitor the patient? The most important quality in an anaesthesiologist is vigilance, and vigilance is accomplished by monitoring the patient with a multitude of devices. The patient is monitored with a blood pressure cuff, an EKG machine, which shows both the EKG patterns and the pulse. Each patient is monitored with a pulse oximeter, which tells us the oxygen concentration in the bloodstream, and each patient is monitored with a capnograph, which shows the patient is ventilating either artificially with our mechanical ventilator or spontaneously breathing.
