Describe the mode of ventilator
The mode of ventilation refers to the way in which a mechanical ventilator delivers breaths to a patient. There are several different modes of ventilation, including:
Controlled mechanical ventilation (CMV): Also known as conventional or volume-controlled ventilation, this mode delivers breaths at a set tidal volume (volume of air delivered with each breath) and rate, regardless of the patient's own breathing efforts.
Assist-control (AC): This mode combines elements of CMV and spontaneous breathing, providing a set rate of breaths and also triggering breaths in response to the patient's own efforts.
Synchronized intermittent mandatory ventilation (SIMV): This mode delivers a set rate of mandatory breaths and allows for spontaneous breaths in between.
Pressure-controlled ventilation (PCV): This mode delivers breaths at a set pressure, rather than a set volume or rate.
Pressure-support ventilation (PSV): This mode provides a continuous stream of pressurized air to support spontaneous breathing efforts.
Continuous positive airway pressure (CPAP): This mode delivers a constant flow of pressurized air to maintain a positive pressure in the airways and prevent collapse.
Each mode of ventilation has its own indications and potential benefits and drawbacks, and the appropriate mode will depend on the patient's condition and the goals of treatment.
