: The coronavirus disease-2019 (COVID-19) is a highly contagious respiratory viral disease for both the general population and healthcare professionals caring for infected patients. Of particular concern is the potential for significant respiratory, cardiovascular, physical, and psychological dysfunctions.: In this context, the current review will focus on the following areas: 1) staying physically active during the COVID-19 pandemic; 2) highlighting the importance of understanding COVID-19 mechanisms; 3) preventing infections for healthcare workers by using personal protective equipment; 4) highlighting importance of respiratory care and physical therapy during hospitalization in patients with COVID-19; and 5) facilitating referral to a rehabilitation program in patients recovering from COVID-19.

Hemodynamics and tissue oxygenation effects after increased in positive end-expiratory pressure in coronary artery bypass surgery.

Background: Cardiac surgery is widely used in the treatment of cardiovascular diseases. However, several complications can be observed during the postoperative period. Positive end expiratory pressure (PEEP) improves gas exchange, but it might be related to decreased cardiac output and possible impairment of tissue oxygenation.

Short-term effects of passive mobilization on the sublingual microcirculation and on the systemic circulation in patients with septic shock.

Background: Active mobilization is not possible in patients under deep sedation and unable to follow commands. In this scenario, passive therapy is an interesting alternative. However, in patients with septic shock, passive mobilization may have risks related to increased oxygen consumption.
