Mechanical Ventilation is a method to assist or replace spontaneous breathing. This can be a life-saving intervention, but can also cause complications and side effects. Mechanical ventilation is often used in intensive care units, home care, and emergency medicine.
Indications[edit]
Mechanical ventilation is indicated when the patient's spontaneous breathing is inadequate to maintain life. It can also be used to sedate the patient for a short period of time, such as during the operation of a ventilator, or during recovery from a critical illness. The main indications for mechanical ventilation are:
- Acute lung injury including Acute Respiratory Distress Syndrome (ARDS)
- Chronic Obstructive Pulmonary Disease (COPD)
- Neuromuscular disease or weakness
- Drug overdose
- Anesthesia
- Sedation
- Coma
Modes[edit]
There are two main modes of mechanical ventilation: Positive Pressure Ventilation and Negative Pressure Ventilation.
Complications[edit]
Complications of mechanical ventilation are mainly related to the method of ventilation and the duration of ventilation. They include:
- Ventilator-associated pneumonia (VAP)
- Barotrauma
- Oxygen toxicity
- Right ventricular failure
- Pulmonary embolism
- Acute Respiratory Distress Syndrome (ARDS)
Weaning[edit]
Weaning is the process of gradually reducing the degree of mechanical ventilation and allowing the patient to resume spontaneous breathing. This can be a complex process and is usually managed by a team of healthcare professionals.
