Respiratory therapy

Blood is the only liquid in the body that is classified as connective tissue. Its function is to transport oxygen, metabolic wastes such as carbon dioxide and nitrogenous waste from the kidneys. Regulation of the body’s pH, body temperature, and maintenance of the liquid volume in the circulatory system. Lastly, protection by way of Leukocyte activation and preventing blood loss by way of the platelets in the blood. Blood is composed of 55% plasma (water, salts, plasma proteins, and other…

The respiratory system is responsible for the balance of oxygen and carbon dioxide in the body to meet metabolic demands. The way a person’s breathe can be affected is by emotions and/or changes in the internal environment. The breathing process is mainly controlled by the brainstem and peripheral system. The brainstem controls several important functions of the body like arousal, breathing, and blood pressure, among other functions. In the brainstem, the medullary respiratory center consists of…

It test how well you inhale and exhale, and it also test how much air your lungs take in with each breath. To perform this test, an instrument called a spirometer is used which measures the volume of air moving in and out of the lungs during pulmonary ventilation. When given this test a person can be standing up or sitting down but whichever one that person must remain in that position throughout the whole test. The person cannot change positions because that will mess of the results from the…

is because it allows the body to be able to respire and be able to get all that it needs to maintain the same state, for example, oxygen throughout the body as well as nutrients to the cells in the body. An example of a transport system is the Respiratory system. This system is required in the body as it helps the body to take in oxygen, this can be done through the lungs, as it allows it to be absorbed into the blood, through the use of the alveolus found within the tissue of the lungs, in…

Volume (AMV) and Extended Mandatory Minute Ventilation (EMMV). MMV can be categorized as volume controlled (VC)-IMV with adaptive and set-point targeting schemes. This mode guarantees the patient will receive a minimum minute volume based the set respiratory rate and tidal volume. Thus, the set breathing rate is the maximum number of mandatory breaths a patient can receive (Chatburn, Khatib, Mireles-Cabodevila, 2014). Furthermore, if the patient is able to breath spontaneously above the set rate…

However, complications will occur in up to 40% of all patients, the risk of a complication being higher for the very young or for adults and in undernutrition. Mortality is highest in infants and younger children. Complications most commonly are respiratory, and pneumonia causes most measles-associated deaths. The pneumonia risk is higher with immune suppression, which can be induced systemically by the virus itself or local immune dysfunction can occur locally within the lungs. The…

What is the difference between the upper and lower respiratory tracts? The upper airways or upper respiratory tract is the parts of the respiratory system lying above the glottis (Vocal cords) • Nose – External breathing organ. • Nasal passages, Inside the nose, the sticky mucous membrane lining the nasal cavity traps dust particles, and tiny hairs called cilia help move them to the nose to be sneezed or blown out • Paranasal Sinuses, - These air-filled spaces alongside the nose help make the…

Cilia and the Protection of the Respiratory Tract Introduction Approximately twelve thousand litres of air is inhaled by one person each day containing environmental stimuli including pathogens and particles such as toxic pollutants and allergens. These must be expelled from the body as it may induce airway inflammation and infection, causing airway diseases. Mucociliary clearance acts as an innate defence against these stimuli, where cilia is a part of this mechanism. Cilia, microscopic…

Allergic asthma and rhinitis, atopic dermatitis (AD), urticaria and gastrointestinal allergy, are common diseases of infants and children. It was recently estimated that 14% of children suffer from AD, 8% from food allergy, and 12% from asthma (1, 2). The cumulated incidence of these diseases in adolescents has been estimated between 25-35%, while the prevalence is about 20% (3). The phenotypic expression of these illnesses varies extensively, being very mild in some cases, severe in many, and…

Introduction Human metapneumovirus is a virus that causes a respiratory infection. Most of the time the virus affects only the nose and throat (upper respiratory tract), but the virus can also affect the lungs and breathing tubes (lower respiratory tract). It is usually more severe if it affects the lower respiratory tract. Most children get an infection caused by this virus by the time they are 5 years old. What are the causes? This condition is caused by human metapneumovirus. You can get this…
