Undertaking A Site Visit - Essay Example ive for Engineers to visit the site quite often to assess if progress being made is in compliance with the safety standards or else they may visit the site in the event that there has been an accident. Indeed, site visiting is not an overnight event hence this essay seeks to outline and explore some of the measures that can be taken when embarking on this particular kind of visit. A contract to construct a project like a shopping complex is often given to a contractor who can in turn subcontract some of the tasks to the others. Basically, the contractor responsible for undertaking the project has all the knowledge about what would be happening at the site but there is every need for Engineers to visit the place to see if there is compliance with expected standards so as to avoid risk of danger such as accidents or injuries or can visit in the event that there has been an accident. First and foremost, it is imperative for the visiting person to gather as much information as possible about the place he is intending to visit. The first thing necessary to do is to obtain as much information as possible about the place from the work provider. The people who are always on site are better informed to have all the instructions and knowledge about the whole area. This is very important since it will give the visitor insight into some of the risks he may expect to enco unter. Besides relying on information from the work providers, it is also important for the visitor to conduct personal research so as to gain in-depth knowledge about the area being visited. The advent of new information and communication especially internet has brought about dramatic changes in the way we do business. Google maps are very useful as far as searching information about any subject is concerned. Conducting personal research is advantageous in that the visitor would familiarise with the place even before visiting since there would be more information that can be accessed online.

Preventing hypoxemia in closed head injury Essay

Preventing hypoxemia in closed head injury - Essay Example In closed head injury, brain is susceptible to further injury caused by cerebral edema since the brain is confined in a calvarium and therefore, cannot expand. Cerebral edema is the accumulation of excess water into the intra and extra cellular spaces of the brain (Cerebral Edema, 2003), and is most often encountered in patients with brain injury. Cerebral edema can cause a lethal effect, which includes cerebral ischemia due to compromised regional or global cerebral blood flow (CBF) and intracranial compartmental shifts due to intracranial pressure gradients that result in compression of vital brain structures (Ahmed, 2007). Thus, it is the primary goal in medicine to manage cerebral edema to maintain regional and cerebral blood flow in order to meet the metabolic requirements of the brain as well as prevent secondary neuronal injury brought about by cerebral ischemia. Tegtmeyer (1998) noted that in order to minimize secondary injuries brought about by closed head injury, priorities of treatment must be geared towards airway, breathing, and circulation. Airway must be maintained to facilitate oxygen delivery to the brain to prevent cascading of secondary injuries. During the injury, the cerebral perfusion pressure drops off rapidly as the blood goes down, and brain volume increases with swelling and edema. Cytotoxic edema which results from closed head injury must be prevented to further damage the brain. And in doing so, hypercarbia and hypoxemia must be corrected. As indicated in the University of Oxford database (2008), secondary brain injury may have been caused by inadequate brain perfusion, and therefore, avoiding and treating hypoxia, hypercarbia, and hypertension are of utmost importance. Increased morbidity and mortality are associated with hypoxemia, hypercarbia, and hypotension in patients with severe head trauma. In line with this, bra in injury causing
