smoke)‚ air pollution‚ dust and exposure to chemicals used in the production of coal‚ cotton and grain. There are many complications of COPD‚ the most common are pneumonia‚ pneumothorax‚ cor pulmonale‚ atelectasis‚ and in severe cases there maybe respiratory insufficiency and failure (Bare‚ Cheever‚ Hinkle‚ & Smeltzer‚ 2010). Nursing management for a patient with chronic obstructive pulmonary disease begins with assessment; gathering information from the patient including detailed medical history

For normal adults‚ arterial blood gas levels include PaCO2 36-44 mmHg‚ HCO3- 22-26 mEq/L‚ and pH 7.35-7.45. With that being said‚ RS has increased levels of PaCO2 and HCO3- with a decreased pH level thus leading to the conclusion that RS is in respiratory acidosis. His PaCO2 level is increased because of impaired gas exchange‚ and HCO3-

pressure gradient is established from alveoli to atmosphere‚ with air being pushed out to the atmosphere into the lower pressure. We call this expiration or breathing out. Control of the ventilation mechanism The ventilation rate is controlled by a respiratory system situated in the hindbrain. In this centre there‚ there are three separate areas 1.the medullary rhythmicity centre‚ controlling the basic rhythm of ventilation and made up of an inspiratory centre and expiratory centre‚ located i the medulla

Exercise 7 Review Sheet Definitions/Explanations: Respiration: The entire process of gas exchange in the body; it includes each of the following: 1. Pulmonary Ventilation (AKA breathing): The follow of air into and out of the lungs. The result of muscle contraction of the diaphragm. Ventilation consists of two parts: a. Inspiration: The process that occurs when atmospheric gas is drawn into the lungs by way of contraction of the diaphragm which causes expansion of the thoracic

Bio Lab: The Effect of Exercise on The Respiratory and Circulatory Systems Ellie Cookson Communication: 2. As the graphs show‚ both breathing rates and pulse rates spike significantly between the resting rates and immediately after exercise. Average breathing rates went from 26.7 breaths/min at sitting rate to 46.4 breaths/min during or immediately after exercise. Pulse rates also increased quite dramatically‚ going from an average of 65 beats/min at rest rate to an average of 100.3 beats/min

Nursing Care in Multi-Organ Disfunction Syndrome When a patient enters the Emergency Department (ED)‚ immediate and accurate assessment is mandatory to ensure prompt medical diagnosis and appropriate care. In the case of Mrs. Baker‚ a 73-year-old female who collapsed in her backyard‚ this assessment will assist in determining the reason for her collapse as well as identifying underlying medical problems that may have led to this incident. Upon her arrival at the ED‚ Mrs. Baker gives her previous

COPD COPD is characterized by airflow limitation that is poorly reversible. Cumulative‚ chronic exposure to cigarette smoking is the number one cause of the disease‚ but repeated exposure to secondhand smoke‚ air pollution and occupational exposure (to coal‚ cotton‚ grain) are also important risk factors. Chronic inflammation plays a major role in COPD pathophysiology. Smoking and other airway irritants cause neutrophils‚ T-lymphocytes‚ and other inflammatory

Plethysmography is used to measure changes in volume in different parts of the body. This can help check blood. The test may be done to check for blood clots in the arms and legs‚ or to measure how much air you can hold in your lungs. Lung plethysmography: You will breathe or pant against a mouthpiece. Clips will be put on your nose to shut off your nostrils. Depending on the information your doctor is looking for‚ the mouthpiece may be open at first‚ and then closed. You will be breathing
