FRANKLIN, NEUROMUSCULAR BLOCKADE
Anesthetized patients under neuromuscular blockade were evaluated during apnea over a 15-minute period before elective surgery. During this study, COWe used TCM4 and TCM5, two transcutaneous COThe gold standard reference method for measuring COAfter arrival of the patient in the operating theatre, the probes of the two TCM monitors were applied on the patient’s chest and an arterial Flowswitch cannula (BD, Franklin Lakes, USA) was placed ultrasound-guided into the radial artery to measure blood pressure and to draw arterial blood samples. Induction and maintenance of general anesthesia were standardized as described earlier [Before start of anesthesia, and again from the start of apneic oxygenation, arterial blood gas samples were drawn every two minutes and p
