Guaranteed Tidal Volume with Volume Control Ventilation
Intermittent Positive Pressure Ventilation, or IPPV, is one of the most common volume-control ventilation modes used in emergency care and surgery.
Volume-control ventilation refers to a specific amount of air known as the tidal volume or Vt that is administered to the patient with each breath. This volume is set in advance and remains constant. The resulting airway pressure depends on respiratory system compliance (how easily the lungs can expand) and the amount of air delivered.
What is IPPV?
IPPV is a type of ventilation method used to take over a person’s breathing when they are unable to do so effectively on their own. IPPV ventilation can be administered both manually and mechanically using either a bag-valve-mask or an IPPV ventilator.
In an IPPV respiratory setting, a machine helps the patient breathe by pushing air into the lungs at set intervals. For this respiratory rate, tidal volume and maximum airway pressure can be set by the user. This method helps ensure oxygen gets into the body and carbon dioxide is removed.
Once the IPPV machine reaches maximum ventilation pressure (pMax), the device will maintain pMax until the end of the inspiratory phase before switching to the exhalation phase. As a result, the full tidal volume may not be delivered if pMax is reached before inspiration is complete.
Use of IPPV Ventilation in EMS
For EMS professionals seeking reliable, easy-to-use ventilation in critical situations, MEDUMAT Easy CPR offers a lightweight, intuitive solution. Designed for out-of-hospital emergencies, it ensures consistent ventilation rates and volumes, supporting both adult and pediatric patients.
The following ventilation parameters can be set:
Vt: Tidal volume (breathing volume) in ml
Freq.: Ventilation rate in bpm
pMax: Maximum inspiratory pressure in cmH2O
