A 66-year-old male started to present symptoms of fever, dyspnea, coughing, asthenia, lack of appetite, nausea, and vomiting. He was admitted to the acute care unit for observation and oxygen therapy, but his oxygen requirements constantly increased due to moderate ARDS. After 12 days of deep sedation, neuromuscular blocking agents, and proning with daily passive range of motion, the patient finally started to initiate active movements and was passively transferred to a chair. However, due to a persisting difficult weaning status, probably related to respiratory muscle weakness, tracheostomy was performed [ventilator settings: pressure support 10 cmH2O, positive end-expiratory pressure (PEEP) 8 cmH2O]. Subsequently, the patient showed significant improvement in his physical functions with active SOEB, chair-transfer with the help of 2 physical therapists, and active in-bed cycling against resistance for 20 minutes (). The strategy was to increase pressure support (by 5 cmH2O) during efforts to reinforce exercise training effects, unloading respiratory muscles. This strategy along with a highly collaborative patient culminated in his rapid improvement in physical function (MRC-SS 58/60, physical function ICU test score 10/12, walking distance 10 m), although he was still experiencing fatigue, inspiratory muscle weakness (maximal inspiratory pressure of −45 cmH2O) and dysphagia upon his transfer to a step-down unit.
This 52-year-old male tested COVID-19 positive 4 days after the beginning of a dry cough, fever, and head and limb pain. One day later, he was hospitalized with exertional dyspnea. He was diagnosed with pneumonia that developed into moderate ARDS needing mechanical ventilation and intermittent dialysis. After extubation, oxygenation was stable with 2 to 3 L/min of oxygen. However, the patient was disoriented and could not communicate verbally. His global weakness (CPAx 11/50) was accompanied by oral and pharyngeal weakness and paresthesia. Spontaneous swallowing frequency and tongue control were severely reduced, and the patient showed insufficient protection from aspiration. This was confirmed by a specialized physical therapist with the Gugging Swallowing Screen, which confirmed severe dysphagia with 2/20 points. He was treated nil by mouth and received dysphagia therapy such as intensive oral stimulation, facilitation of swallowing, and training of protection mechanisms. After initial agitation and disorientation, the patient started to communicate in single-word phrases, but dysphagia continued to be severe with massive oral and pharyngeal dry saliva residuals that compromised his paresthesia and required regular mouth care. Over the next days, the patient managed to swallow pureéd food and mildly thick fluids under supervision, although cough strength was still weak (Gugging Swallowing Screen 13/20, CPAx 30/50). Nevertheless, he continued to progress and became capable of independent food ingestion (Gugging Swallowing Screen 20/20, CPAx 39/50) before his discharge to a rehabilitation clinic 25 days after admission.
