This 57-year-old male was admitted to the ICU with dyspnea, heavy dry cough, and fever 6 days after testing positive for COVID-19. Initially, he was able to exercise and sit in a chair with a physical therapist, but progressive respiratory failure necessitated intubation and proning. The patient had large amounts of bronchial mucus and required regular suctioning along with respiratory therapy. Secretions were assessed with pulmonary auscultation (presence of crackles) and by analyzing expiratory flow on the ventilator (sawtooth pattern). When suctioning failed to improve these clinical signs, 1 to 2 physical therapists used manual airway clearance techniques. The goal of these techniques was to sufficiently increase expiratory flow for effective airway clearance while avoiding alveolar collapse. To achieve this, manual compressions on the chest and abdomen were performed with just enough intensity to modify expiratory flow. After extubation, the patient was still unable to effectively clear his mucus due to weak cough. He continued to need intensive manual airway clearance techniques, nasal rinsing to induce cough and to help expectoration as well as upper and lower airway suctioning. To this end, the patient was treated up to 6 times per day/night. Additional physical therapist interventions included passive range of motion, assisted exercising, and mobilization. At the time of writing, the patient was still in the ICU without ventilatory support.
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.
