Intermittent mandatory ventilation during anaesthesia using the Manley Servovent ventilator

Area of Science:

• Anesthesiology
• Respiratory Medicine
• Medical Devices

Background:

• Intermittent mandatory ventilation (IMV) combines spontaneous and mechanical breathing.
• Selecting appropriate ventilation modes is crucial for patient outcomes during anesthesia.
• The Manley Servovent Model MS is a specific ventilator model.

Purpose of the Study:

• To evaluate the Manley Servovent Model MS ventilator for delivering IMV.
• To assess the suitability of IMV for patients undergoing prolonged anesthesia without muscle relaxation.

Main Methods:

• Twenty-five patients undergoing anesthesia were ventilated using the Manley Servovent Model MS.
• The ventilator was set to deliver intermittent mandatory ventilation (IMV).
• The gas source and ventilator modifications were noted.

Main Results:

• The Manley Servovent Model MS successfully delivered IMV without modification.
• This ventilatory mode was utilized during prolonged operations.
• The need for muscle relaxation was absent in the selected patient group.

Conclusions:

• The Manley Servovent Model MS is capable of delivering IMV using a single gas source.
• IMV via this device is suitable for specific prolonged anesthetic procedures.
• IMV offers advantages over spontaneous or mechanical ventilation in selected cases.
