Mechanical ventilation is a medical intervention that uses a machine to assist or replace spontaneous breathing. It is commonly used in patients with severe pulmonary conditions or during surgical procedures requiring anesthesia.
congrats on reading the definition of mechanical ventilation. now let's actually learn it.
Mechanical ventilation can be either invasive, using an endotracheal tube, or non-invasive, using masks and other devices.
Patients on mechanical ventilation often require specialized nutritional support due to increased metabolic demands and the need for optimal respiratory muscle function.
Nutritional strategies for mechanically ventilated patients include monitoring caloric intake, protein levels, and micronutrient balance to prevent malnutrition and promote recovery.
Overfeeding can lead to complications such as hypercapnia (elevated CO2 levels) in mechanically ventilated patients.
Enteral nutrition is generally preferred over parenteral nutrition in ventilated patients unless contraindicated.
