Spontaneous Modes of Mechanical Ventilation | CPAP, Volume and Pressure Support
Показать описание
What are the Spontaneous Modes of Mechanical Ventilation? Are you familiar with CPAP, Volume Support, and Pressure Support?
➡️ Spontaneous Modes of Mechanical Ventilation
Keep in mind that, in order to use any of the following modes, the patient must be breathing spontaneously.
➡️ Continuous Positive Airway Pressure (CPAP)
In CPAP, a continuous pressure that is above atmospheric pressure is delivered and maintained throughout the entire breathing cycle. Again, the patient must be breathing spontaneously to be in this mode because no mandatory breaths are given. This is a useful mode for weaning patients off of the ventilator.
➡️ Pressure Support Ventilation (PSV)
A mode of mechanical ventilation is which the patient’s spontaneous breaths are supported by the ventilator during the inspiratory phase of breathing. As the patient triggers a breath, the ventilator assists by adding pressure to make breathing easier. The level of pressure is preset by the operator, so you have control over how much support you give the patient. For example, the higher the level of pressure support that is set, the easier it will be for the patient to take a breath. In PSV, the breaths are time-cycled and pressure-limited.
PSV is often used to help the patient overcome the airway resistance that is caused by the endotracheal tube. For example, if a patient who needs to be weaned from the ventilator is in SIMV. If their endotracheal tube size is too small, the airway resistance would be increased and would make weaning difficult. That's when PSV would come in handy to help the patient overcome the airway resistance so that they can be extubated.
➡️ Volume Support (VS)
A mode of mechanical ventilation is which the ventilator delivers a supported breath to help the patient reach a set tidal volume. This mode is totally dependent on the patient's effort, meaning that, the machine varies the inspiratory pressure support level with each breath in order to achieve the target volume. This mode is not quite as common as some of the others, but it's often used to wean patients from anesthesia.
