Respiratory system

Introduction and Clinical Question: Viral croup remains a common cause of upper respiratory obstruction in the pediatric population and its barking cough can often be heard in the pediatric clinic and local emergency departments. Multiple studies have shown the use of glucocorticoids results in a faster recovery with fewer return visits and hospital admissions, as well as a decrease in the use of epinephrine (2). However, in cases were the patient or caregiver refuses an injection or where…

Pseudobulbar Affect Have you ever laughed so hard you literally couldn't stop? How about when you cried so hard you thought the tears would never stop? You probably have experienced both of those situations and felt extremely embarrassed or uncomfortable. There are people who suffer from uncontrollable laughter and crying. Pseudobulbar affect is a condition that has taken over people's lives with it's symptoms, treatments, and how it impacts their social, political, and daily lives. PBA or…

Explain the physiological changes that occur in the cardiovascular and respiratory systems in response to exercise. One of the main physiological changes that occur within the cardiovascular system in response to exercise is heart rate. When engaging in exercise, the amount of energy required increases instantaneously within the skeletal muscles. This sudden demand creates increasing stress on the cardio-respiratory system to remove the waste products and carbon dioxide from the cells and…

human body’s cardiovascular and respiratory systems must integrate and adapt to changing conditions—especially during incremental increases in submaximal exercise to maximal exercise. The coordination of cardiovascular and respiratory systems coalesce to form what is known as the cardiorespiratory system (Lotric & Stefanovska, 2000). Within muscle cells there are extremely limited stores for anaerobic energy; thus, a well-coordinated cardiovascular and respiratory system must be maintained to…

environment to the cells in the body. Biochemistry defines respiration as the metabolic process by which cells utilize glucose and oxygen to produce Adenosine Triphosphate (ATP). Inspiration, which is an active part of respiration, is initiated by the respiratory control center in medulla oblongata. Nerve impulses from medulla oblongata causes diaphragm and the external intercostal muscles to contract, which leads to the expansion of the thoracic cavity. According…

the heart, etc. After the surgery, there is a recovery process and the heart may not even fully heal for some patients. Since the heart may not be able to work optimally, respiration system of the patients may also be affected (Westerdahl et al, 2016). The surgery process itself may also affect the respiratory system by traumatizing the cells and muscles in general, thus reducing the capacity of the lung for respiring and breathing. One study suggests that the thoracic cavity may also have been…

Pneumonia was chosen as the priority pathophysiology because it further deteriorates the individual’s immune system through the active bacterial growth, and compromises the individual’s ability to maintain a patent airway. Thus, the earlier the treatment for pneumonia begins, the fewer risks of complicating treatments associated with cancer. However, if treatment is delayed, the respiratory system is further suppressed as the bacterial pneumonia progresses and increases the individual’s risk for…

Breathing is not just a matter of breathing through inspiration and expiration. Abnormal breathing patterns deals with the absent of breath sounds at certain times and the presence of normal breath sounds in certain areas where they are normally not heard. There are different types of abnormal breathing patterns that are caused with certain illnesses such as Cheyne-Stokes respiration, Kussmaul breathing, Biot’s respiration, apnea, paradoxical breathing and apneustic breathing. There are…

Difference: The difference in the upper respiratory and lower respiratory tract is their location . The organs of the upper respiratory tract are located outside the chest cavity, whereas the lower respiratory tract are located inside the chest cavity. Upper respiratory tract infection, are conditions that affects the nose, sinus, pharynx or larynx. Conditions commonly are • tonsillitis, • pharyngitis, • laryngitis,sinusitis, • otitis media, • common cold. These conditions are basically…

beneficial to many of the body systems. Further investigation towards the effects of respiratory muscle training for patients with chronic obstructive pulmonary disease is critical. Exercise therapy is a regular component in the management of various (chronic) disorders, such as musculoskeletal, neurological, cardiovascular, and respiratory disorders. Respiratory diseases are defined as a group of lung diseases that block airflow and make it difficult to breathe. Respiratory diseases are…
