Rate – normally described in breaths per minute. Normal adult: 12-20 bpm/cpm * Eupnea – normal respiration that is quiet, rhythmic, and effortless. * Tachypnea/Polypnea – rapid respiration, quick and shallow breaths (greater 20cpm) * Bradypnea – slow breathing (less than 12 bpm/cpm) 2.

... I. Factors Involved in Blood Circulation A. Blood Flow - the actual VOLUME of blood moving through a particular site (vessel or organ) over a certain TIME period (liter/hour, ml/min) B. Blood Pressure - the FORCE exerted on the wall of a blood vessel by the blood contained within (millimeters of Mercury; mm Hg) blood pressure = the systemic arterial pressure of large vessels of the body (mm Hg) C. Resistance to Flow (Peripheral Resistance) - the FORCE resisting the flow of blood through a vessel (usually from friction) 1. viscosity - a measure of the "thickness" or "stickiness" of a fluid flowing through a pipe a. V water < V blood < V toothpaste b. water flows easier than blood 2. tube length - the longer the vessel, the greater the drop in pressure due to friction 3. tube diameter - smaller diameter = greater friction D. Relation Between Blood Flow, Pressure, Resistance difference in blood pressure ( P) Blood Flow (F) = peripheral resistance (R) a. increased P -> increased flow b. decreased P -> decreased flow c. increased R (vasoconstriction) -> DECREASED flow d. decreased R (vasodilation) -> INCREASED flow II.

...overview of care for the adult patient with sepsis, focusing on sepsis identification and the first 6 hours of goal-directed treatment according to current guidelines. Defining sepsis Sepsis is the presence of infection along with systemic manifestations of infection. If sepsis isn’t recognized and treated early, it progresses rapidly to severe sepsis, defined as sepsis plus sepsis-induced organ dysfunction or tissue hypoperfusion. Sepsis-induced tissue hypoperfusion is defined as infection-induced hypotension, elevated lactate level, or oliguria.1 24 l Nursing2014 l April Copyright © 2014 Lippincott Williams & Wilkins.

...sepsis, and septic shock is key to early recognition. Early recognition allows for appropriate treatment to begin sooner, decreasing the likelihood of septic shock and life-threatening organ failure. Once sepsis is diagnosed, early and aggressive treatment can begin, which greatly reduces mortality rates associated with sepsis. sep•sis (ˈsep-səs) n. Sometimes called blood poisoning, sepsis is the body's often deadly response to infection or injury (Merriam-Webster, 2011) Sepsis is a potentially life-threatening condition caused by the immune system's reaction to an infection; it is the leading cause of death in intensive care units (Mayo Clinic Staff, Mayo Clinic 2010). It is defined by the presence of 2 or more SIRS (systemic inflammatory response syndrome) criteria in the setting of a documented or presumed infection (Rivers, McIntyre, Morro, Rivers, 2005 pg 1054). Chemicals that are released into the blood to fight infection trigger widespread inflammation which explains why injury can occur to body tissues far from the original infection. The body may develop the inflammatory response to microbes in the blood, urine, lungs, skin and other tissues. Manifestations of the systemic inflammatory response syndrome (SIRS) include abnormalities in temperature, heart, respiratory rates and leukocyte counts. This is a severe sepsis that arises...

...CNE V Continuing Nursing Education Objectives and instructions for completing the evaluation and statements of disclosure can be found on page 224. What Is Normal?' Evaluating Vital Signs Dehra Van Kuiken, Myra Martz Huth ital signs (VS) are indicators of physiological functioning and include temperature, respiratory rate, fieart rate (pulse), and blood pressure (BP). Health care professionals measure VS to assess, monitor, evaluate, and document an individual's physiological status or change in condition (Royal College of Nursing, 2011). Depending on the individual's condition, VS are monitored and recorded routinely by policy, tradition, or expert opinion, whether needed or not (Evans, Hodgkinson, & Berry, 2001; Zeitz & McCutcheon, 2006). Five years ago, pédiatrie nurse leaders and evidencebased practice (EBP) experts from children's hospitals across the country voiced concerns about the frequency of VS at a National Summit for Pédiatrie and Adolescent EvidenceBased Practice (Melnyk et al., 2007). This summit resulted in our team formulating a clinical question, searching for the evidence, critically appraising the evidence, and formulating conclusions on normal parameters. Before the question on the frequency of ys could be addressed, two fundamental questions needed exploration, and thus, became the focus of our work. The questions are: • Among pédiatrie patient ages 1 through 5 years, what are "normal" VS parameters? • Among pédiatrie patient ages 1 through 5 years...

BLIXEN, PhD, RN Department of General Internal Medicine, The Cleveland Clinic Cultural and clinical issues in the care of Asian patients s A B S T R AC T Special problems of Asian patients have considerable impact on diagnosis and treatment, and the number of persons of Asian ancestry seen in primary care in the United States is increasing. Knowledge of how to provide optimal care despite language barriers, low socioeconomic status, different health beliefs and practices, and medical issues unique to this heterogeneous group is crucial to competent health care. with Asian patients include language barriers, low socioeconomic status, traditional health beliefs and practices, and epidemiologic issues. This article presents three case studies that illustrate how these problems can affect the health care of Asian patients, and describes ways to deal with them constructively. We also discuss what diseases are more common and what conditions have unique clinical aspects in this population. Asians: The fastest-growing minority Asians and Pacific Islanders are the fastest growing ethnic minorities in the United States, and are predicted to number more than 17 million by 2010.1 This heterogeneous population is from many cultures and speaks many languages—the 1990 US Census identified 25 distinct Asian...

...systems allow for maintenance of heartbeat, blood pressure, breathing, digestion, excretion, thermoregulation, visual accommodation, and procreation. Automatic or involuntary processes occur due to the actions of organs, hormones from the endocrine system, and neuron communication from the nervous system. The portion of the nervous system that regulates these involuntary processes is aptly called the autonomic nervous system (ANS). The ANS is composed of afferent and efferent neurons that work to communicate messages to and from the brain and spinal cord, also known as the central nervous system (CNS). The...

...Nursing Management of a Patient with Raised Intracranial Pressure after Traumatic Brain Injury and Dealing with Family Anxiety. Introduction The aim of this assignment is to explore, analyse and evaluate the nursing management of raised intracranial pressure (ICP) and family anxiety after head injury. In order to obtain a wider knowledge of the care of patients with raised ICP, a literature review was carried out. From this information I hope to improve the standard of care and ultimately patient outcome. The anxiety felt by family members are large and therefore I have decided to discuss this in my assignment. Consent has been sought from the next of kin. Confidentiality will be maintained in accordance with Nursing and Midwifery Council (NMC 2008). Patient’s Presentation Aldi is a 42 year old male who was found by police lying in the street, with loss of consciousness and believed to be assaulted. His eyes, lips and face was swollen. He was brought to the nearest hospital via ambulance as he had a seizure episode. In A&E it was noted that Aldi has sustained a head injury associated with a decrease level of consciousness and seizure activity. His pupils are both 2mm and reacting to light. His Glasgow Coma Scale (GCS) was 9-10. Opening eyes on pain, incomprehensible sound and moving all limbs. GCS is a worldwide recognized scale for documenting neurological assessment (Mavin,2008). After the initial presentation in A&E his neurological condition was rapidly...
