consciousness. While an overdose is not always fatal or intentional‚ it can cause a host of life-long health problems‚ regardless. An overdose survivor can experience heart‚ liver‚ kidney‚ and respiratory failure. Permanent brain damage can result from hypoxia. Since drug use of any kind can alter the mood receptors in the brain‚ an overdose can severely affect mental health. Depression‚ paranoia‚ loss of interest‚ memory loss and suicidal tendencies can also stem from a drug overdose.

In pregnancy‚ the renin–angiotensin–aldosterone system (RAAS) plays an important role for the equilibrium of salt and water in mother and child. All components of the RAAS are altered during pregnancy (1‚ 2). Renin concentrations are elevated due to extra-renal secretion in decidua and ovaries through estrogen stimulation (2). An increase in angiotensinogen production in the liver is observed in pregnant women. By contrast‚ the angiotensin-converting enzyme is reduced. These changes result in an

Question 1. A. AIRWAY– Maintaining a clear airway is always considered a high priority because airway is essential for gas exchange (Ramkumar‚ 2011). However‚ the patient has a patent airway. Therefore‚ the nursing strategy is to conduct an airway assessment “look‚ listen and feel” continuously to detect any changes. This is to provide immediate respiratory care if the patient’s airway is compromised (Higginson‚ Jones & Davies‚ 2011). This is a low priority. B. BREATHING – Respiration is altered

Introduction: Aircraft systems are amalgam of different systems within systems. Among many other system‚ Environmental control system is an important system of an aircraft which provide the aircraft with the basic necessities of maintaining comfortable atmosphere for passengers. In specific terms‚ it is the system which provides conditioned air supply‚ temperature control and optimum pressurization of cabin for both crew and passengers. Besides‚ some other functions like fire detection and suppression

Macroautophagy‚ a cellular process regulated by p53 is an intracellular system that involves the break down of cytoplasmic contents within the lysosome. This mechanism is a form of adaptation to cellular stress such as starvation‚ trophic factor deprivation‚ hypoxia‚ endoplasmic reticulum (ER) stress and oxidative stress (Levine & Abrams‚ 2008). Through adaptation‚ it allows the prevention of cell death. There are three types of autophagy: macroautophagy‚ microautophagy‚ and chaperone-mediated autophagy (CMA)

studies have been attended to evaluate the progression such as Chawla et al.‚ 2014 explained that damage of endothelial tissues‚ as part of tubulo-interstitial damge‚ and vascular insufficiency may lead to severe harmful rounds of tissue ischemia and hypoxia‚ sequentially involving renal cellular function. The combination of vascular inadequacy‚ glomerular hypertension‚ and interstitial fibrosis is a destructive set of self-reinforcing processes that extends injury‚ inhibits restoration‚ and lead to progressive

Anaphylaxis reaction to medications or latex‚ this may be avoided by reviewing the patients allergies prior to surgery. Hypoxia or other respiratory complication‚ which occurs with inadequate ventilation this‚ can be caused by many different factors‚ which include anesthetic agents‚ aspiration and the patient position on the operating table.

increased vascular permeability. ARDS results in: bilateral pulmonary edema and atelectasis despite no evidence of left heart failure (e.g.‚ normal pulmonary capillary wedge pressure (PCWP). ARDS is present when the ALI results in such severe hypoxia that at the PaO2/FIO2 ratio is 200 mm Hg or less. Approximately 10% to 15% of intensive care patients meet the criteria for ARDS in the typical ICU. ARDS is often accompanied by multiple organ system failure. When ARDS was first described‚ its
