Ventilatory modalities for patients with SARS-COV-2: A literature review

Abstract

Ventilatory modes are different ways of interacting the device in the patient's respiratory cycle, and some variants can change, such as frequency, pressure, volume, support if the device does all the stimulation of the drive or not, and if the patient will do it spontaneously or totally dependent on the mechanical ventilator to survive. The objective of the study was to describe the most appropriate ventilatory modes for patients diagnosed with SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus) with the best response to the condition. In addition, recognizing the patient's pulmonary plasticity and evaluating the most appropriate Positive Expiratory Pressure (PEEP) for an improvement in the clinical condition. The method used was a literature review using scientific research, published in databases on the Scientific Electronic Library Online (Scielo) and National Library of Medicine (NLM) platforms. The result of the research showed that patients with SARS-CoV-2 are not intubated early, because if there is no evidence for this, the patient may have permanent and irreversible lesions. Thus, it is concluded that each patient has his or her own individuality, and should be taken into account his or her previous comorbidities, requiring an evaluation of the patient's respiratory drive and pulmonary plasticity, as well as the application of mini PEEP titration.
