Summary
We enhanced the intermittent mandatory ventilation (IMV) technique to a synchronized IMV (s-IMV) technique. This new method precisely delivers patient-triggered inspiratory volumes, improving respiratory insufficiency treatment.
Area of Science:
- Mechanical Ventilation
- Respiratory Therapy
- Biomedical Engineering
Context:
- Conventional intermittent mandatory ventilation (IMV) can lead to asynchronous breathing between patient and ventilator.
- Optimizing ventilator support is crucial for patients with respiratory insufficiency.
Purpose:
- To describe the development and principle of a synchronized intermittent mandatory ventilation (s-IMV) technique.
- To adapt existing Bird Mark 7 machines for patient-triggered ventilation.
Summary:
- The s-IMV technique utilizes two Bird Mark 7 machines with a specialized tubing system.
- An electronic set with a thermistor and bedside monitor detects patient's spontaneous breathing.
- This allows for precise delivery of variable inspiratory volumes synchronized with the patient's respiratory efforts, enabling controlled artificial respiration, s-IMV, and spontaneous breathing modes.
- The system allows for adjustable F.I.O2 (0.21-1.0), CPAP, and PEEP.
Impact:
- Offers a flexible and adaptable ventilation strategy for patients with respiratory insufficiency.
- Enhances patient-ventilator synchrony, potentially improving patient comfort and outcomes.
- Provides a method to modify treatment from controlled ventilation to spontaneous breathing support.
