Mechanical ventilation is a supportive process in that we are aiming to treat the underlying cause of the patients problem whilst we support their lung function. Hopefully once the underlying problem is solved we can then take the patient off the ventilator.
Very basically then;
Normalise arterial blood gas:
- Normalise acid base balance
- Normalise ventilation
- Normalise oxygenation.
Remove or reduce the patients work of breathing by unloading the respiratory muscles. We need to aim to do this in a synchronised manner.
Indications for ventilation
Type I Respiratory failure- Hypoxeamic failure.
- Low oxygen status for example caused by:
- Congestive heart failure
- Pulmonary embolism
Type II Respiratory failure- Hypercapnic failure.
- High carbon dioxide for example caused by:
- Chronic obstructive airways disease
- Neuromuscular disease.
- Airway swelling
