Short Duration Of Action Potentials Essay - 1299 Words

Rational Systemically, the patient,CJ is stable, his arm is very painful, to the crew, CJ’s injury is not life threatening however the pain is real and precautions need to be taken to stabilise the limb and to minimise nerve or soft tissue damage. Adequate pain relief is required. Nitrous Oxide,( commonly referred to as Entanox) provides analgesic properties suitable for fast and effective pain relief . Pharmacodynamics Administration of N2O is painless, with a rapid onset and a short duration of action. The onset is approximately 1 to 5 minutes and the recovery time is 3 to 5minutes once the gas has been with-drawn.( Pasaron R., Burnweit C. ,Zerpa J., Malvezzi L.,Knight C., Shapiro T., Ramos-Irizarry C., Velis E.) Inhaled N2O gas molecules are absorbed into the blood stream from the lungs. As noted by Oglesbee, it provides sedation stabilizing the neurons in the brain to prevent action potentials. N2O has low solubility in blood and is transported in solution without binding to proteins. It diffuses rapidly across the alveolar– arterial membrane and is excreted unchanged, mainly through the lungs. ( S C Faddy, S R Garlick) Nitrous oxide may increase pulse rate and have depressant effects on respiration.( BOC New Zealand data sheet.)

In previous experiments, action potentials were observed. Action potentials are an all or nothing response and do not deteriorate as it travels down the length of the nerve. Action potentials are directed by voltage-gate pumps. One type of action potential is a compound action potential (CAP). CAP is an artificial response of a nerve when all the axons are simultaneously electrical stimulated. It is known that individual action potentials are voltage-dependent therefore it elicitsRead MoreA Biphasic Compound Action Potential1653 Words   |  7 Pagesbiphasic compound action potential, both the positive and negative recording electrodes were used, with the negative recording electrode at position ‘D’ and the positive recording electrode at position ‘E’ (refer to Figure 1). The extracellular bipolar re cording takes the difference between what the negative electrode picked up and what the positive electrode picked up. The first, positive deflection of the CAP was caused by the extracellular negative charge of the action potential recorded by theRead MoreThe Maturity Gap of the Banks Assets and Liabilities919 Words   |  4 PagesWhat is the duration gap of the bank of its assets and liability, that falls within the maturity of 5 years and 10 years? (Please assume current market yield is flat at 6.5%) (8 marks) For the bank’s assets reflected on the balance sheet, if the current market yields are flat at 6.5%, the largest impact of the yield effects the 5-year T-note in terms of duration. Duration drastically falls for this security compared to the 5-year personal loan that is repriced yearly in which the duration is positiveRead MoreZopiclone Is A Drug First Developed By Rhone Poulenc Rore1452 Words   |  6 Pagesincreasing the conductance of chloride ions and hyperpolarizing the neuron, the frequency of action potentials is reduced. This causes an inhibition of brain activity, causing zopiclone to have hypnotic, sedative, muscle relaxant, anxiolytic, and anticonvulsant effects (4). Zopiclone acts much in the same way as benzodiazepines when used to treat insomnia, but was believed to have less adverse effects, and less potential for developing tolerance and addiction. As a result, it was first marketed as a betterRead MoreSuboxone Therapy1568 Words   |  7 PagesCurrently there are many pros and cons for therapists choosing this type of treatment. In order for the patient to agree to the right form of therapy, it is important that all the side effects and potential dangers be fully understood beyond just the potential benefits to Suboxone. Some of the potential downsides to this treatment could cause ongoing damage for the patient in the future. In October of 2002, the Food and Drug Administration (FDA) approved the use of Suboxone for the treatment inRead MoreHow Diabetes Affects The Body1610 Words   |  7 Pagesmellitus (DM). The different types of insulin vary with respect to onset and duration of action. Short-, intermediate-, and long-acting insulin are available. Rapid-acting insulin is used whenever a rapid onset and short duration are appropriate (eg, before meals or when the blood glucose level exceeds target and a correction dose is needed). Rapid-acting insulin are associated with less hypoglycemia than regular insulin. Short-acting insulin is less commonly used than the rapid-acting insulin in patientsRead MoreThese impacts are possible to predict using some tools, being Modelling and Spatial the most800 Words   |  4 Pagesstripping, grading, trenching and backfilling, can cause effects on the soil capability and terrain stability through alteration of the morphological and physical properties, changing the soil erodibility, that is the characteristic based on the potential for soil detachment by runoff and raindrop impact. The changes of the soil physical properties together with the steep terrain, located on the base of the Coast Mountains, and the regular earthquakes caused by the Juan de Fuca plate boundary, increaseRead MoreCognitive Behavioral Therapy ( Cbt )1417 Words   |  6 Pages(p.408-09). CBT focuses on the premise that thoughts trigger an emotional response, which in turn triggers a behavior. It states that all behaviors are internally derived from our thoughts instead of being externally triggered. CBT is short term in duration and can provide rapid emotional progress since it is solution focused, often using concrete homework assignments to be able to assist clients in refocusing their current paradigm into something more constructive and positive in nature.

Bond funds, which consist of limited duration l oans with a fixed interest rate, use collections of bonds for a moderately safe investment. Money market funds offer the lowest financial returns on investments, but they are the most secure way to invest. Investments with higher risks generally correlate to higher potential returns, but it is always possible that even a low risk investment strategy could lose money.

Many people suffer from obstructive airway diseases, most commonly from chronic obstructive pulmonary disease (COPD) and Asthma. Short-acting beta-agonist (SABA) are a type of bronchodilator that have been successfully used for decades to treat acute airway obstruction. The two most commonly used SABA bronchodilators that treat acute obstructive airways are albuterol and levalbuterol
