Apr 06 2002· Ocular microtremor (OMT) is the smallest of all eye movements with median peak to peak amplitude estimated as being about 0.001 mm (18 arc-seconds). OMT spectra are characterised by one or more peaks at frequencies between 40 and 100 Hz in healthy subjects. Coakley has suggested the use of OMT as a monitor of depth of anaesthesia.

Apr 01 2001· Ocular microtremor (OMT) is a small high frequency tremor of the eyes present in all individuals. This tremor is caused by high frequency extra‐ocular muscle stimulation which originates in the oculomotor area of the brainstem. 2 The oculomotor neurons are ‘embedded in the reticular formation’ of the brainstem. 3 However neural activity

Apr 01 2001· Ocular microtremor (OMT) is a fine high frequency tremor of the eyes caused by extra-ocular muscle activity stimulated by impulses emanating in the brain stem. Several studies have shown that the frequency of this tremor is reduced in patients whose consciousness is reduced by anaesthesia or head injury. Therefore OMT may possibly be used to

Mar 15 2006· The procedure lasted for 15 min during which lung ventilation was manually assisted. The F É co 2 values during the procedure were 4.0–4.5 kPa. The child became stridulous on emergence from anaesthesia. The laryngeal mask airway was promptly removed and bag and mask ventilation with oxygen 100% was started but the stridor persisted.

In this thesis two novel methods are presented for online removal of ocular artifacts (OA) from EEG without the need for EOG electrodes attached to the face. Both methods are fully automated and can remove the effects of both eye movements and blinks. The first method employs a high speed eye tracker and three frontal EEG electrodes as a reference to any nonlinear adaptive …

Under general anesthesia you will be unconscious throughout the operation. Some surgeries are done under monitored anesthesia care or sedation. You receive medicines to relax you and block pain but you remain either conscious or in an unconscious state from which the team can easily wake you when necessary during surgery.

A pediatric ophthalmologist—a doctor who specializes in eye surgery for children—will do your child’s eye examination under anesthesia. When general anesthesia is needed there are special rules for eating and drinking before the procedure. This procedure takes about 45 minutes but recovery from the anesthesia might take several hours.
