the body with oxygen and dispose of carbon dioxide. In order for this to happen‚ at least four events called respiration must occur. The first is the pulmonary ventilation. The air must move in and out of the lungs so that the gases in the alveoli are continuously refreshed. This process is better known as “breathing”. Next is external respiration‚ when a gas exchange between the alveoli and the pulmonary blood must take place. Then there is respiratory gas transport‚ where oxygen and carbon dioxide

Theory of Self-Care‚ respiratory illnesses affect several aspects of a patient’s ability to provide care to themselves and maintain independence. A patient with end-stage COPD may be unable to be without oxygen supplementation‚ they may not have the ability to cook or clean themselves without being exhausted from their lack of oxygen. Just the task of sitting up and eating a meal can be difficult when their every breath is a gasp through their nose and mouth to get the next little bit of air their lungs

The other listed disorders are more likely to cause problems with hypercapnia because of ventilatory failure.

blood through the pulmonary and systemic circuit. Include a description of gas exchange within the lungs. The function of the heart is to pump blood throughout the body. The heart pumps blood containing oxygen from the lungs to body. It passes blood without oxygen back to the lungs for more oxygen. The heart has four chambers; the two upper chambers are called atriums‚ and the two lower chambers are called ventricles. The left atrium is located above the left ventricle‚ and they are separate by a

MANAGEMENT OF BREATHLESSNESS IN LUNG CANCER Breathlessness is one of the most common symptoms of advanced cancer‚ particularly lung cancer. Reported incidence varies between 30% - 70%(J. Carner).30% of all the patient experience it during some part of their illness and it goes as high 79% with lung cancer. (Mora Kearney). Despite being prevalent it is most of the time not recognised by the health professional‚ when it is really serious. May be due to the fact that patient sometimes do not come
