Ventilatory support refers to medical interventions that assist or replace spontaneous breathing in patients who are unable to breathe adequately on their own. This support can be provided through various methods, including mechanical ventilation, which uses machines to deliver air into the lungs, and non-invasive ventilation, which uses masks to help patients breathe without intubation. The need for ventilatory support can arise from conditions such as pneumonia, chronic obstructive pulmonary disease (COPD), or acute respiratory distress syndrome (ARDS). By ensuring adequate oxygen delivery and carbon dioxide removal, ventilatory support plays a crucial role in stabilizing patients and improving their overall respiratory function.
