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.
Paramedics found this 59-year-old female with dyspnea and an oxygenation of 65% on room air and performed immediate tracheal intubation. Moderate ARDS with reduced lung compliance was diagnosed and treated with deep sedation, neuromuscular blocking agents, and prone positioning.\nOn day 14, a trial of sitting on the edge-of-bed (SOEB) was performed, while she was still intubated and under pressure support ventilation. SOEB required 3 physical therapists to maintain the position, but resulted in a significant increase in her level of consciousness and collaborative state. The next day, she was able to hold her head and sit for about 15 minutes with 2 therapists. Her muscle strength indicated ICU-acquired weakness, with a Medical Research Council sum-score (MRC-SS) of 40/60; still she continued with small but consistent improvements and started to participate actively in physical therapy sessions. She was encouraged to mobilize herself with exercises against gravity and was actively transferred to a chair each day with the help of 2 physical therapists. She was successfully extubated, but presented postextubation dysphagia. The physical therapy team closely monitored her for secretion management and cough stimulation and continued her physical rehabilitation. On day 19, she started to walk with a walking aid, although at this point oxygen desaturation during exercise training became evident (89% with 3 L/min of oxygen). After 25 days, she was transferred to the institution’s rehabilitation facilities, where a battery of tests indicated persistent physical function impairment (MRC-SS 52/60, physical function ICU test score17 9/12, Timed Up & Go 23 seconds, short physical performance battery 4/12).
