http://fromnewtoicu.com/blog/2016/3/11/train-of-four WebWhen train of four monitoring is "used continuously, each set (train) of stimuli normally is repeated every 10th to 12th second. Each stimulus in the train causes the muscle to contract, and 'fade' in the response provides the basis for evaluation." These sets are called trains because their shape bears the resemblance of a train.

WebAug 26, 2013 · Train-of-four neuromuscular monitoring is commonly conducted with a subjective measurement, either as a simple train of four count (TOFC) or train of four ratio (TOF). The latter refers to when there is already a TOFC of 4, and subsequent assessment is made for fade in T4 compared to T1. WebMar 10, 2006 · You will gently hold your Pt's hand and feel his thumb and the number of twitches that the T-O-F produces is the result of the procedure.
