Respiratory acidosis is a state in which there is usually a failure of ventilation and an accumulation of carbon dioxide. The primary disturbance of elevated arterial PCO2 is the decreased ratio of arterial bicarbonate to arterial PCO2, which leads to a lowering of the pH. In the presence of alveolar hypoventilation, 2 features commonly are ...May 1, 2023 · Corticosteroids are drugs used in the management and treatment of almost all areas of medicine.

Well before any written historical record, chronic wounds of all shapes and sizes have plagued patients and created a significant burden on their caretakers. It has long been noticed that some patient factors are more likely to be associated with better wound healing [1][2][3]. Likewise, certain wound types have been noted to be ...Swyer-James-MacLeod syndrome (SJMS), also known as Swyer-James syndrome or hyperlucent lung syndrome, is an uncommon syndrome of unilateral functional hypoplasia of the pulmonary vasculature and emphysema, with or without associated bronchiectasis. The condition was first described simultaneously in the 1950s by a respiratory physician William ...Jul 25, 2023 · As a result, pursed-lip breathing helps support breathing by the opening of the airways during exhalation and increasing excretion of volatile acids in the form of carbon dioxide preventing or relieving hypercapnia. Through purse-lip breathing, people can have relief of shortness of breath, decrease the work of breathing, and improve gas exchange.In the early nineteenth century, Charles Dickens reported in his book "The Posthumous Papers of the Pickwick Club" on the obesity hypoventilation syndrome (OHS), which is defined as alveolar hypoventilation in an obese individual during wakefulness that cannot be explained to other conditions that lead to hypercapnia such as chronic obstructive lung disease (COPD).[1] OHS is linked to ...A lung abscess is a microbial infection of the lung that results in necrosis of the pulmonary parenchyma. It is classified as acute (less than four weeks) or chronic (more than four weeks) depending on the duration. Based on their etiology, they can be classified as primary, if they occur in the absence of underlying pulmonary lesions or secondary if they occur in the presence of underlying ...May 1, 2023 · Wheezing is the symptomatic manifestation of any disease process that causes airway obstruction. Rene Laennec's development of the stethoscope in 1816 has enabled a better appreciation of wheeze at the bedside, in comparison to the previously established practice of ear-to-chest auscultation. Wheeze is a musical, high-pitched, adventitious sound generated anywhere from the larynx to the distal ...Amlodipine, an oral dihydropyridine calcium channel blocker, demonstrates prolonged efficacy by inhibiting voltage-dependent L-type calcium channels.

Mounier-Kuhn syndrome is a rare disorder, as only approximately 300 cases have been reported to date. ...The measurement of carbon dioxide (CO2) was first developed in the early 1900s; however, it was complex and of limited clinical use.[1] On the most basic level, end-tidal CO2 (ETCO2) detectors are used to measure the exhaled concentration of carbon dioxide. The concentration of exhaled CO2 correlates to the arterial concentration of CO2, although multiple factors can impact the relationship ...Asbestosis is an interstitial lung disease caused by inhaling asbestos fibers (See Image.

Rapid recognition, assessment, and treatment are paramount to patient outcomes. Gone are the days of definitive airway management as first-line therapy.Boyle's law is a gas law that describes the relationship between the pressure and volume of gas for a mass and temperature. This law is the mechanism by which the human respiratory system functions. Boyle's law is equivalent to PV = K (P is pressure, V is volume, K is a constant), or one may state that pressure is inversely proportional to the volume.[1]Multifocal atrial tachycardia (MAT) is a supraventricular tachycardia with a rapid, irregular atrial rhythm arising from multiple ectopic foci within the atria. This arrhythmia is characterized by a heart rate of greater than 100 beats per minute with organized atrial activity yielding three or more different non-sinus P-wave morphologies in the same lead. There are irregular PP intervals and ...Respiratory failure can be classified based on chronicity (i.e., acute, chronic, and acute on chronic). A thorough understanding of respiratory failure is crucial to managing this disorder. If either type of respiratory failure is not identified and addressed early, it will become life-threatening and lead to respiratory arrest, coma, and death.Overview.

Respiratory alkalosis is by definition a disease state where the body's pH is elevated to greater than 7.45 secondary to some respiratory or pulmonary process.[1]Cardiopulmonary resuscitation (CPR) is a collection of interventions performed to provide oxygenation and circulation to the body during cardiac arrest. Our current modern-day approach to this process stemmed from the work of a handful of doctors in the 1950s and has now evolved into the process that will be discussed further here. The most widely accepted guidelines in North America are those ...Upper respiratory tract infections can be defined as self-limited irritation and swelling of the upper airways with associated cough with no proof of pneumonia, lacking a separate condition to account for the patient symptoms, or with no history of COPD/emphysema/chronic bronchitis.
