1.The reflexes, movement. So there is not much

1.The Harvard criteria and Glassgow coma scale are of similar in assessment. The Harvard criteria also assess the eye response, responsiveness, receptivity, reflexes, movement. So there is not much difference in assesing the MR Houben.2. To determine whether to remove someone from life support plays acucial role. The medical technology also plays a role along with ethical aspect. The health condition can be assesed by using PET scan and ECMO. They brought new challenges to the end of life care. Those helps to identify the brain activity as well as patients responsiveness to the treatment. Whether the cellular activity is reacting or not. Based on this, the medical technology helps to identify whether to continue or remove the client from lifes upport3. Glassgow coma scale and Harvard criteria are of absolutely similar. The assesment is of similar in both sclaes. The criteria are,Harvard criteria asssessment:A series of 4 parameters delineated by Harvard medical school for irresversible coma,Harvard criteria for brain death-Unreceptivity and unresponsivenessNo movement or breathingNo reflexesFlat electroencephalogram(confirmatory)Glassgow coma scale:Glassgow coma scale assess the level of consciousness and reaction to stimuli based on eye opening, verbal response performance and motor responsiveness.To describe the level of consciousness in a person following a traumatic brain injury.It is used to assses the severity of an acute brain injuryIt is simple, reliable, corelates with outcome following severe brain injuryHelps to identify initial, subsequent loss of consciousness in a person after a brain injuryThe Glassgow coma scale and Harvard criteria are of sbsolutely similar, there is no room for doubt using these scales. The aim of both scales is to identify responsiveness, receptivity, movement, reflexes.4. Technology should be used to determine or define death:Technolgies like PET scan and Extra corporeal membrane oxygenation(ECMO) plays a key role in dtermining or defining death.PET scans, EMCO have brought new challenges to to the end of life care.PET scans helps in detection of brain activityIt shows the body anatomy like MRI or CT scanPET scan can actually detect cellular activity in tissuesIt shows residual brain activityExtracorporeal membrane oxygenation(ECMO) is an emerging resuscitating technology used to resuscitate the patient in severe life threatening conditionWhen heart or lungs have failed, if not recovered, ECMO can sustain the life for weeks or even months, not definitely.Eventually the synthetic tubing that connects ECMO machine to the body can get clogged/ infected or obstructed flow. No formal stopping point for ECMO, that means physicians has to decide when to turnoff.Once ECMO machine turned off, death will likely to come with in minutes
