Synchronized Intermittent Mandatory Ventilation (SIMV)
Synchronized Intermittent Mandatory Ventilation (SIMV)
Type of ventilation where the ventilator provides a preset number of breaths per minute, while allowing the patient to breathe spontaneously in-between.
Assist Controlled Ventilation (ACV)
Assist Controlled Ventilation (ACV)
Type of ventilation where the ventilator assists the patient's every breath, delivering a preset tidal volume.
Positive End-Expiratory Pressure (PEEP)
Positive End-Expiratory Pressure (PEEP)
Pressure applied at the end of each exhalation to keep the alveoli ( tiny air sacs in the lungs) open and prevent collapse, improving oxygen exchange.

Study Notes
Ventilation Types and Functions
- Mandatory Ventilation: Administers preset positive airway pressure breaths, ensuring the patient receives adequate ventilation regardless of spontaneous efforts.
- Patient-Controlled Breathing: Allows patients to dictate their breathing rate, promoting a sense of autonomy and comfort while still benefiting from assisted ventilation.
Positive End-Expiratory Pressure (PEEP)
- Purpose of PEEP: Maintains alveolar inflation at the end of expiration, preventing atelectasis (collapse of lung units) and improving gas exchange by increasing functional residual capacity.
Breathing Augmentation and Monitoring
- Pressure Support Ventilation: Monitors negative inspiratory efforts and augments the patient's tidal volume, providing necessary support during spontaneous breathing efforts.
- Controlled Mechanical Ventilation (CMV): Requires sedation and muscle relaxants to ensure that the patient does not interfere with the ventilator’s function and follows a set breathing pattern, offering complete control over ventilation timing and volume.
Additional Ventilation Types
- Volume-Controlled Ventilation: Delivers a predetermined volume and rate regardless of the patient's own breathing effort, ensuring consistent ventilation but limited adaptation to the patient's needs.
- Synchronized Intermittent Mandatory Ventilation (SIMV): A form of pressure support that synchronizes with the patient’s own breathing, allowing for natural breathing patterns to be maintained alongside mandatory breaths.
