Modes of mechanical ventilation
Imagine you are blowing up a balloon. When you inhale air into your lungs, your chest expands and air flows into your lungs. When you exhale, your chest relaxes and air flows out. This is how you breathe normally.
However, if you are sick or your lungs are damaged, you may need help to breathe. This is where mechanical ventilation comes in. Mechanical ventilation is a machine that helps you breathe by using a tube that goes into your airway and delivers air and oxygen to your lungs.
There are different ways mechanical ventilation can be used (or modes). Depending on what your body needs, the machine can be programmed to deliver different amounts of air, pressure, and oxygen. Here are some of the modes of mechanical ventilation:
1. Volume-controlled ventilation: This mode delivers a certain amount of air with each breath. This mode is used when your lungs are weak and need more volume to help them fill with air.
2. Pressure-controlled ventilation: This mode delivers air at a certain pressure, which is set by the machine. This mode is used when your lungs are stiff and need more pressure to help them expand.
3. Assist-control ventilation: This mode allows you to breathe on your own, but the machine assists you with additional breaths if you need them. This mode is used when you have trouble breathing on your own.
4. Continuous positive airway pressure (CPAP): This mode delivers a continuous flow of air, which helps keep your airway open. This is used when you have trouble keeping your airway open on your own.
These are just a few examples of the modes of mechanical ventilation. Your doctors will decide which mode is best for you based on your condition and your body's needs. Mechanical ventilation can be uncomfortable, but it is an important therapy that can help you breathe and recover from illness or injury.
