SUCCESS RATE OF NON-INVASIVE MECHANICAL VENTILATION IN PATIENTS CUSTOMED AT THE INTENSIVE CARE UNITS OF CASU - HOSPITAL IRMÃ DENISE IN CARATINGA/MG

Abstract

Non-invasive mechanical ventilation is applied to patients with the aim of improving the diffusion of oxygen to tissues, the technique eliminates the need for sedatives and avoids physical and respiratory damage commonly caused by invasive mechanical ventilation. The present study describes and seeks to analyze the success rates of the procedure in the Intensive Care Units of CASU - Hospital Irmã Denise through the parameters of non-invasive ventilation and the HACOR Score, which evaluate the failure rate through the combination of heart rate, acidosis, level of consciousness, oxygenation and respiratory rate. The patients who were examined in the study are within the classification of carriers of hypoxemic and hypercapnic diseases and being subdivided by diagnosis (chronic obstructive pulmonary disease; acute pulmonary edema, community-acquired pneumonia). Of the analyzed patients, NIV was considered successful in 50% of the cases. A higher success rate is observed among patients with acute pulmonary edema (75%) and exacerbated COPD (60%), while failures were more prevalent among patients with pneumonia (80%). These results are in line with the premise of the Brazilian Guidelines for Mechanical Ventilation, which establish an expectation rate of 75% for a hypercapnic population and 50% for hypoxemic patients with the use of NIV. Therefore, further discussion is needed on the use of NIV in patients with diseases that lead to hypoxemia, in order to seek more efficient strategies for the non-invasive treatment of acute respiratory failure in this population.
