    Abstract:
    OBJECTIVE: To identify which noninvasive ventilation (NIV) masks are most commonly used and the problems related to the adaptation to such masks in critically ill patients admitted to a hospital in the city of São Paulo, Brazil. METHODS: An observational study involving patients ≥ 18 years of age admitted to intensive care units and submitted to NIV. The reason for NIV use, type of mask, NIV regimen, adaptation to the mask, and reasons for non-adaptation to the mask were investigated. RESULTS: We evaluated 245 patients, with a median age of 82 years. Acute respiratory failure was the most common reason for NIV use (in 71.3%). Total face masks were the most commonly used (in 74.7%), followed by full face masks and near-total face masks (in 24.5% and 0.8%, respectively). Intermittent NIV was used in 82.4% of the patients. Adequate adaptation to the mask was found in 76% of the patients. Masks had to be replaced by another type of mask in 24% of the patients. Adequate adaptation to total face masks and full face masks was found in 75.5% and 80.0% of the patients, respectively. Non-adaptation occurred in the 2 patients using near-total facial masks. The most common reason for non-adaptation was the shape of the face, in 30.5% of the patients. CONCLUSIONS: In our sample, acute respiratory failure was the most common reason for NIV use, and total face masks were the most commonly used. The most common reason for non-adaptation to the mask was the shape of the face, which was resolved by changing the type of mask employed. OBJETIVO:: Identificar as interfaces de ventilação não invasiva (VNI) mais utilizadas e os eventuais problemas relacionados a sua adaptação em pacientes críticos internados em um hospital na cidade de São Paulo, SP. MÉTODOS:: Estudo observacional, com pacientes acima de 18 anos admitidos nas unidades de pacientes graves que usaram VNI. Foram coletados a causa de uso da VNI, interface utilizada, esquema de uso da VNI, adaptação e motivos para a falta de adaptação à interface. RESULTADOS:: Avaliamos 245 pacientes, com média de idade de 82 anos. A insuficiência respiratória aguda foi a causa mais frequente de uso da VNI (71,3%). A interface mais utilizada foi a máscara facial total (74,7%), seguida por máscara facial e máscara facial quase total (24,5% e 0,8%, respectivamente). Em 82,4% dos pacientes, a VNI foi utilizada por períodos. A adaptação adequada à interface ocorreu em 76% dos pacientes. As máscaras tiveram de ser trocadas em 24% dos pacientes. Houve adaptação adequada à máscara facial total e à máscara facial em 75,5% e em 80,0% dos pacientes, respectivamente. A adaptação foi inadequada nos 2 pacientes que utilizaram a máscara facial quase total. A causa mais frequente da falta de adaptação foi o formato da face, em 30,5% dos pacientes. CONCLUSÕES:: Nesta amostra, a insuficiência respiratória aguda foi a causa mais frequente de uso da VNI, e a máscara facial total foi a interface mais utilizada. A causa mais comum da falta de adaptação à máscara foi o formato da face, que foi resolvida após a troca da interface.
