Abstract:
Respiratory syncytial virus (RSV) is a common cause of respiratory disease in all age groups, with young children and older adults experiencing the most severe illness. The coronavirus disease 2019 (COVID-19) pandemic resulted in striking changes in the activity of seasonal respiratory viruses, including RSV. After a period of suppression early in the pandemic, an interseasonal surge of RSV occurred in 2021. Viral activity was detected primarily in children and young adults after relaxation of public health measures, but without the usual proportional increases in infections and hospitalizations in older adults who were likely still adhering to stricter public health measures.

Common Respiratory Disorders
Upper respiratory disorders impact the airways above the vocal cords, encompassing areas like the nose, sinuses, and throat. Various conditions fall under this category, including the common cold and allergic rhinitis. These disorders can stem from several causes,...

Palpation Findings
During a respiratory assessment, palpation can reveal several vital abnormalities:
Acute Respiratory Failure-II
The underlying physiological abnormalities that contribute to hypoxemic respiratory failure include:
Factors Affecting Pulmonary Ventilation
Alveolar Surface Tension
The alveolar fluid lines the luminal surface of the alveoli and exerts a force called surface tension. This force is caused by the polar water molecules in the liquid being more strongly attracted to each...

Ensure that patients are monitored continuously for their response to therapy, including changes in...
