Abstract
Objective: To analyze the importance of gasometric data in the extubation process and in the withdrawal of mechanical ventilation from patients in an intensive care unit of a hospital in the Zona da Mata Mineira. Method: Documentary research, retrospective from August to December 2018, of a descriptive nature. Results: In the initial sampling, 75 weaning control samples were analyzed, and 20 were excluded from patients who did not pass the spontaneous breathing test. Thus, the sample consisted of 55 intensive care patients, 31 men (56.4%) and 24 women (43.6%), with a minimum age of 13 years and a maximum of 88 years. Conclusion: It was observed that the PAO2 and PCO2 values of arterial blood gas in the weaning process did not interfere in the successful withdrawal of IMV. Hemogasometric data contribute positively to the weaning process and withdrawal of mechanical ventilation, being part of the evaluation for the decision to withdraw or cancel the Spontaneous Breathing Test (RET) and return to artificial ventilation, in addition to predicting the need for Ventilation Non-invasive (NIV) after extubation in PCO2-retained patients at the time of ERT.
