FIGURE 27.1 Intracranial pressure (ICP)–volume curve. The curve has three parts: A flat part representing good compensatory reserve (A–B), an exponential part representing reduced compensatory reserve (B–C), and a final…
The [Na+] is multiplied by 2 to account for the accompanying anions (mostly chloride and bicarbonate) that provide electroneutrality. The corrections in the glucose concentration and BUN are to convert…
2. Multifocal causes are the most diverse group and account for the largest cohort of cases of coma [4]. Trauma is the leading cause of coma followed by vascular lesions…
Posteriorly, each vertebra has a spinous process attached to bilateral laminae to form an arch. The laminae connect to bilateral transverse processes and then the pedicles, until finally fusing with…
3. Indications for intervention a. Both the decision to intervene and the manner of intervention are dependent upon the degree of impairment the patient is experiencing as well as the…
Women by a 3:2 ratio are more likely to have a SAH than men [3]. B. Outcome. Approximately 15% of patients with acute SAH do not survive to hospital admission….
c. The basic frequency bands are thought to be rhythmic activity resulting from neural connections with the brainstem and thalamus (sometimes referred to as EEG pacemakers). d. Simple methods of…
FIGURE 8.1 Coronal section of the sella turcica demonstrating the anatomic relationship between the pituitary gland and cranial nerves, carotid arteries, and the cavernous and sphenoid sinuses. (By permission of…
FIGURE 4.1 Schematic diagram of the intracranial pressure (ICP)–volume relationship (elastance). As intracranial volume increases (A to B) compensation occurs resulting in minimal increase in ICP, but as elastance decreases…
