Nursing care in mechanically ventilated (MV) neonatal patients are essential to prevent complications. However, omissions in the application of this type of care have been documented. This study is an exploratory, observational, non-experimental, descriptive and transversal, which investigates the application of pediatric nursing care to patients with MV. The sample consisted of 15 nurses from the neonatal intensive care service. The results reveal the constant practice of some cares (monitoring of oxygen saturation, temperature, and pigmentation), but the partial or total omission of others (arterial gas monitoring, sedation, and others). In conclusion that simple cares are the most performed, while those that require more time or material are less realized. Research into the causes of these omissions is necessary.
