How would the resistance of Cari’s airways be affected by excess mucus and fluid in her lung? The excess mucus and fluid in the lungs would increase the resistance of Cari’s airways because of the small diameter the buildup would cause and the fluid would have some alveoli underwater where they can’t function properly causing more friction from the buildup. 5. How would Cari’s lung compliance be altered as her alveoli fill with fluid due to pneumonia? Cari’s lung compliance would increase from trying to force gases in and out of the alveoli that are filled with fluid.
Noor Findlay (Lisa) 16/01/15 Unit 645 – Lead and manage infection prevention and control within the work setting 1. Understand current infection prevention and control policies procedures and practices. 2.1 Summarise national and local policies for infection prevention and control. Following is national and local policies:- There are laws and legal regulations about infection prevention and control. Most of the legal regulations relating to infection Prevention and control come under the Health and Safety at Work Act; this act is about ensuring a safe work place for employers, Employees and members of the public by minimising accidents at work.
Emphysema affects the maximal volume of air that can be exhaled. It also increases their RV (residual volume) and FRC ( Functional Residual Capacity) 6. If a person is receiving supplemental oxygen to restore blood oxygen levels, why might it be better to administer a combination of oxygen and carbon dioxide rather than pure oxygen? If you provide a combo of both, your body has to work harder to maintain the oxygen level because you are putting in both O2 and CO2. Your body will get rid of CO2.
Cold and/or dry air can cause airways in the lungs to narrow. High levels of pollution in the air such as smoke are also a trigger. And lastly, high levels of pollen and allergens in the air contribute to triggering exercise-induced asthma. Allergens include pet hair, dust, chemicals, and mold (5). The second category of causation is dietary factors.
• Children are likely to be more vulnerable to exposure to air pollution compared to adults for the following reasons; their lungs are still growing and developing, their immune and metabolic systems are still developing, they suffer from frequent respiratory infections, and they are more active outdoors than adults and therefore breathe in higher doses of outdoor pollutants. • Older adults: Older people are more likely to be affected by air pollution, perhaps due to generally weaker immune systems, or undiagnosed respiratory or cardiovascular health
However if he arteries become completely blocked it can cause a heart attack. Respiratory system e.g. asthma Asthma is caused by inflammation of the airways. The airways are small tubes that carry air in and out of the lungs. When we come in contact with or do something that irritates our lungs, we trigger off an asthma attack.
Extrinsic factors include airway infection and increased air pollution and intrinsic factors such as increased oxidative stress and altered immunity (Tsoumakidou & Siafakas, 2006), although the exact mechanisms are not known (Bathoorn et al, 2008). Ball (1995) states that infections play a major role in the aetiology of acute exacerbations. It is known that patients with COPD have significant impairment of the lung defence mechanisms and colonisation of the bronchial system seems to be an important consequence of the disease, particularly in exacerbations according to Erkan et al (2008). Discussion The prevalence of COPD appears to increase with age according to Devereux (2006) and Soriano (2000). However, it is interesting that they attribute this increase solely to aetiological factors rather than the normal process of ageing.
By classifying communities' ability to suppress fires, ISO helps the communities evaluate their public fire-protection services. The program provides an objective, countrywide standard that helps fire departments in planning and budgeting for facilities, equipment, and training. And by securing lower fire insurance premiums for communities with better public protection, the PPC program provides incentives and rewards for communities that choose to improve their firefighting
During the process of fighting fires there is alot to be aware of such as thick smoke. Smoke entering your lungs can be a huge risk when it comes to your cardiovascular health. However each firefighter is given a face mask to help you to breathe and protect your lungs from the smoke. How protective are these masks? Alot of the masks contain center ventilation orifice allowing easy air exchange and helps prevent buildup of CO2(the thick smoke created by fire).
Assessment Objectives 1, 2 and 3 should focus upon identifying the key hazards to health safety and security and the corresponding measures in place to minimise such risks. The list of hazards is not exhaustive and candidates could identify additional hazards by investigating an airport close to their own location. Most airports and airlines have useful websites (see Resources section) that describe many of the security measures in place and give advice on health issues for passengers. In addition, the airport and airline industry, and its regulators, produce a lot of material on safety that could help with
