Pulmonology

During quiet inspiration the diaphragm and external intercostals contract. When the diaphragm contracts it moves down which increases the size of the thoracic cavity from top to bottom. When the external intercostals contracts it elevates the ribs which increases the size of the thoracic cavity from front to back and from side to side. During forced inspirations sternocleidomastoid, serratus anterior, and pectoralis minor contract. Lastly, during forced expiration the abdominal muscles and the…

Ventilation and perfusion work together in the body to provide oxygen and dispose of carbon dioxide. Ventilation provides tissue and organs oxygen by the process of mechanical inspiration and exhalation of the lungs. This provides the alveoli within the lungs with oxygen, as well as the ability to expel waste products like carbon dioxide. Perfusion provides the tissues and organs with oxygen by the mechanism of diffusion between the pulmonary capillaries and alveoli. Ventilation Ventilation…

There are many diseases out there that effect the lungs, and can be life-threatening. They affect millions of people every year. Some examples would be lung cancer and acute respiratory distress syndrome. Cancer is a disease that, among other things, effects the communication between cells. Acute respiratory distress syndrome prevents oxygen from getting into the blood. With so many people being at risk, it can lead some people to wonder why the cure hasn’t already been created. There are many…

Q1. What clinical findings are likely in R.S. as a consequence of his COPD? Ans. The clinical findings are likely in R.S. as consequences of his COPD are SOB, history of smoking, thick sputum and sputum may be purulent, productive cough, wheezing, rhonchi and decreased breath sounds, dyspnea, chills, muscle aches, fatigue may be evident during meals, when walking and even after rest. In chronic obstructive lung problems are known because resistance in airflow increases and causes obstruction in…

The distinction between pimples and zits zits vs pimples Pimples has a tendency to surface while the oil and melanin glands in the pores and skin get clogged. This outcome in a raised pop which produces pus. pimples are generally infectious in nature and generally tend to spread if carelessly popped main to worsened situations. On the other hand, pimples result from the blockage that occurs within the pores and skin pores. Pimples appear as raised pustules or papules and are very painful. Acne…

Amy Parsons is a 16-year-old “A” student with no known medication, environmental, or food allergies and a history of several URI and common colds who presented to clinic with chief complaint of “I go through periods when I cough a lot, I never cough up anything; its just a dry, hacking cough. I have coughing episodes after I swim in the pool, and it seems like I just can't take a deep breath.” Aside from her periodic nonproductive cough and childhood respiratory complications, Amy denies any…

In the human body lies an organ that can float on water the lungs. In that organ there is a cell called Alveoli. The major thing the Alveoli does is take air. The Alveoli can be deeply affected by Lung Cancer. Lung Cancer can kill the alveoli cell and cause death. The alveoli cell is apart of the respiratory system. The respiratory system includes the mouth, nose, throat, lungs, and more. It takes in oxygen either through the nose or mouth and removes the carbon dioxide, this is also called…

Human health effects caused by DINP Diisononyl phthalate (DINP) is a phthalate ester that is commonly used as a plasticizer to make softness and flexibility to polyvinyl chloride (PVC) products, such as children’s toys. There are many health effects of DINP migrating from children’s toys during mouthing activities. Some concerns are on the kidney and liver, it causes decrease in body weight, an increase in liver weight and and changes in hypertrophy. If toys find their way into children’s…

1. On presentation, this patient’s overdose has resulted in the following symptoms: bradycardia, bradypnea, hypotension, hypothermia, hypoxia, and non-responsive to pain. For this patient, an endotracheal tube would be placed to protect the airway and start mechanical ventilation, since the patient is having difficulty maintaining spontaneous ventilation. This will also protect the airway from potential aspiration. Continuous oxygen therapy at 100% to help improve the patient’s hypoxia.…

Review Article Treatment of Respiratory Distress Syndrome in Preterm Infants: A Review Keishera Aldonza Candidate for Bachelor, Department of Medical Laboratory Sciences at University of Massachusetts Dartmouth Introduction Preterm infants often display signs of respiratory distress syndrome at birth due to the immaturity of the lung structure, with respiratory morbidity decreasing as gestational age increases. Respiratory distress syndrome is caused by a deficiency of surfactants. Surfactants…
