Ventilation clinical practice guidelines in adults with COVID-19 were released by the European Society of Intensive Care Medicine and the Society of Critical Care Medicine.
Ventilation-Related Recommendations and Suggestions for Adults With COVID-19
It is suggested to start supplemental oxygen if the peripheral oxygen saturation (SPO2) is less than 92%. It is recommended to start supplemental oxygen if the SPO2 is less than 90%.
In the event of acute hypoxemic respiratory failure on oxygen, it is recommended that the SPO2 be maintained at no higher than 96%.
In patients with acute hypoxemic respiratory failure despite conventional oxygen therapy, it is suggested that a high-flow nasal cannula be used rather than conventional oxygen therapy.
In patients with acute hypoxemic respiratory failure, it is also suggested that a high-flow nasal cannula be used over noninvasive positive-pressure ventilation.
In these patients with acute hypoxemic respiratory failure, in the event a high-flow nasal cannula is not available and the patient has no urgent indication for endotracheal intubation, it is suggested that a trial of noninvasive positive-pressure ventilation be conducted, with close monitoring and short-interval assessment for worsening of respiratory failure.
While considered an option, no recommendation was made regarding helmet noninvasive positive-pressure ventilation versus mask noninvasive positive-pressure ventilation.
In patients receiving either noninvasive positive-pressure ventilation or high-flow nasal cannula, it is recommended they be closely monitored for worsening respiratory status; early intubation in a controlled setting is recommended if worsening occurs.
In patients with acute respiratory distress syndrome (ARDS) who are on mechanical ventilation, it is recommended to use low-tidal-volume ventilation (4-8 mL/kg of predicted body weight) versus higher tidal volumes (>8 mL/kg).
In patients with ARDS who are on mechanical ventilation, it is recommended to target plateau pressures at less than 30 cm water.
In patients with moderate-to-severe ARDS who are on mechanical ventilation, it is suggested to use a higher positive end-expiratory pressure (PEEP) strategy versus a lower PEEP strategy. When using a higher PEEP strategy (ie, PEEP >10 cm water), monitor patients for barotrauma.
In patients with ARDS who are on mechanical ventilation, it is suggested to use a conservative fluid strategy versus a liberal fluid strategy.
In patients with moderate-to-severe ARDS who are on mechanical ventilation, it is suggested to use prone ventilation for 12-16 hours versus no prone ventilation.
In patients with moderate-to-severe ARDS who are on mechanical ventilation, it is suggested to use, as needed, intermittent boluses of neuromuscular blocking agents versus a continuous infusion, to facilitate protective lung ventilation.
Use of a continuous infusion of neuromuscular blocking agents is suggested in the event of persistent ventilator dyssynchrony, a need for ongoing deep sedation, prone ventilation, or persistently high plateau pressures.
In patients with ARDS who are on mechanical ventilation, routine use of inhaled nitric oxide is not recommended.
In mechanically ventilated patients with severe ARDS and hypoxemia despite optimization of ventilation and other rescue strategies, a trial of inhaled pulmonary vasodilator is suggested as rescue therapy; if rapid improvement in oxygenation is not observed, taper off treatment.
In mechanically ventilated patients with severe ARDS and hypoxemia despite optimization of ventilation, use of recruitment maneuvers is suggested over not using recruitment maneuvers. If recruitment maneuvers are used, staircase (incremental PEEP) recruitment maneuvers are not recommended.
In those patients on mechanical ventilation who have refractory hypoxemia despite optimization of ventilation and who have undergone rescue therapies and proning, it is suggested to use venovenous extracorporeal membrane oxygenation (EMCO) if available; alternatively, refer the patient to center that has ECMO. However, because EMCO is resource-intensive and it requires experienced centers/healthcare workers and infrastructure, it should only be considered in carefully selected patients with severe ARDS.
