Abstract

Abstract: This narrative review highlights the relevance of noninvasive mechanical ventilation (NIV) as an essential intervention to optimize respiratory safety in obese patients during the perioperative period, a population characterized by markedly reduced functional residual capacity, increased alveolar collapse, and hypoventilation that elevate the risk of critical hypoxemia.
The analyzed evidence demonstrates that CPAP (Continuous Positive Airway Pressure) and BiPAP (Bilevel Positive Airway Pressure) improve oxygenation by enhancing alveolar recruitment and prolonging the safe apnea time, offering superior benefits compared with conventional oxygenation techniques. During the preoxygenation stage, multiple trials confirm that positive pressure reduces the incidence of peri-intubation hypoxemia, with greater impact in patients with elevated BMI or obstructive sleep apnea (OSA). During anesthetic induction, the application of CPAP between 7 and 10 cmH2O or BiPAP with an appropriate IPAP–EPAP (Inspiratory Positive Airway Pressure–Expiratory Positive Airway Pressure) gradient improves respiratory stability, reduces ventilatory effort, and prevents the rapid desaturation characteristic of this population. In the postoperative period, contemporary studies such as EXTUB-OBESE demonstrate that early application of NIV reduces respiratory failure and increases reintubation-free time, with particularly pronounced benefits in patients with morbid obesity. Additionally, BiPAP offers advantages in the presence of hypoventilation or hypercapnia, whereas CPAP is more effective when atelectasis predominates. Based on the findings of this review, it is recommended to use NIV systematically during preoxygenation in obese patients, select the modality according to the predominant pathophysiology, initiate CPAP and BiPAP with safe and titrated parameters guided by clinical response, and implement prophylactic use after extubation in patients with BMI ≥ 40 kg/m² or high respiratory risk.

Resumen:  La presente revisión narrativa destaca la relevancia de la ventilación mecánica no invasiva (VNI) como una intervención esencial para optimizar la seguridad respiratoria del paciente con obesidad durante el periodo perioperatorio, una población con marcada reducción de la capacidad residual funcional, mayor colapso alveolar e hipoventilación que incrementan el riesgo de hipoxemia crítica. La evidencia analizada demuestra que las modalidades CPAP (Presión Positiva continua en la Vía Aérea) y BiPAP (Presión Positiva en la Vía Aérea en Dos Niveles) mejoran la oxigenación al aumentar el reclutamiento alveolar y prolongar el tiempo seguro de apnea, con beneficios superiores a las técnicas convencionales de oxigenación. En la etapa de preoxigenación, múltiples ensayos confirman que la presión positiva disminuye la incidencia de hipoxemia peri intubación, con mayor impacto en pacientes con IMC elevado o apnea obstructiva del sueño (AOS).
Durante la inducción anestésica, la aplicación de CPAP entre 7 y 10 cmH₂O o BiPAP con un diferencial IPAP–EPAP (Presión Positiva Inspiratoria- Presión Positiva Espiratoria) adecuado mejora la estabilidad respiratoria, reduce el esfuerzo ventilatorio y previene la desaturación rápida característica de esta población. En el postoperatorio, estudios  contemporáneos como EXTUB-OBESE demuestran que la VNI aplicada precozmente reduce el fracaso respiratorio y aumenta el tiempo libre de reintubación, siendo especialmente beneficiosa en pacientes con obesidad mórbida. Además, el BiPAP ofrece ventajas en presencia de hipoventilación o hipercapnia, mientras que el CPAP resulta más efectivo cuando predomina la atelectasia. Con base en los hallazgos de esta revisión, se recomienda utilizar VNI de forma sistemática en la preoxigenación del paciente obeso, seleccionar la modalidad según la fisiopatología predominante, iniciar CPAP y BiPAP en parámetros seguros y titulados según respuesta clínica, e implementar su uso profiláctico tras la extubación en pacientes con IMC ≥ 40 kg/m² o riesgo respiratorio elevado.
