The incidence of post-stroke depression peaks at 3–6 months and usually resolves within 1–2 years after the stroke, although a minority of patients can go on to develop chronic depression. The diagnosis of post-stroke depression is complicated by other consequences of stroke such as fatigue and psychomotor retardation – which do not ...
Overdistension of alveoli and cyclic atelectasis (atelectotrauma) are the primary causes for alveolar injury during positive pressure mechanical ventilation.Severe injury to alveoli causes swelling of the tissues (edema) in the lungs, bleeding of the alveoli, loss of surfactant (decrease in lung compliance) and complete alveoli collapse ().
The alveoli of the lungs fill with edema fluid, causing dyspnoea, cough and frothy or bloodstained sputum. Gas exchange is affected, and as hypoxia increases there may be a loss of consciousness. Oxygenation in divers may be affected by breathing gas mix and partial pressure reduction due to ascent.
With conventional ventilation where tidal volumes (V T) exceed dead space (V DEAD), gas exchange is largely related to bulk flow of gas to the alveoli.With high-frequency ventilation, the tidal volumes used are smaller than anatomical and equipment dead space and therefore alternative mechanisms of gas exchange occur.
Right side depicts what occurs after injury to the alveolus during the acute/exudative phase. Once the initial insult has damaged the alveoli and begun the process of DAD, the condition will typically progress in three phases: exudative, proliferative, and fibrotic. [6] Below are the description of the phases, paraphrased from Sweeney et al ...
Recovering from a stroke can be difficult, especially when you’re also expected to overhaul your diet to prevent further complications. Patients who are recovering from a stroke in the hospital ...
A physician will listen to the patient's lungs to help determine if there is likely a lower lung disease. Depending on the type of alveolar lung disease, the listener may hear "crackles" that indicate an excess of fluid in the lungs or an absence of lung sounds in certain regions which may indicate poor ventilation due to consolidation of pus ...
Patients who are clinically stable with no need for supplemental oxygen after extraction may be discharged from the hospital the same day as the procedure. [24] Routine imaging such as a follow-up chest x-ray are not needed unless symptoms persist or worsen, or if the patient had imaging abnormalities previously to verify return to normal. [ 24 ]
