How to Choose the Right Heart-Lung Machine for Cardiac Surgery
Understand the Clinical Application
Identify the typical procedures your facility performs:
- Adult cardiac surgeries CABG, valve repair/replacement
- Pediatric cardiac surgeries
- Long or complex procedures requiring advanced monitoring or control
Choose the Pump Technology
The pump is the core of the machine:
- Roller Pumps: Most traditional; reliable, simple control.
- Pros: Well-established, easy to use.
- Cons: Risk of tubing wear and rupture.
- Centrifugal Pumps: Increasingly popular; better control of flow and pressure.
- Pros: Lower risk of hemolysis, safer at low flow.
- Cons: More expensive, slightly more complex.
Evaluate Monitoring and Safety Features
You’ll need robust real-time monitoring and safeguards:
| Feature | Why It Matters |
| Flow Sensors | Accurate perfusion tracking |
| Pressure Monitors | For arterial and venous lines |
| Air Bubble Detectors | Prevent embolism |
| Temperature Control | Maintain patient hypothermia/rewarming |
| Integrated Oxygenator Monitoring | For real-time blood gas analysis |
Modularity and Expandability
- Modular design: Allows you to add or remove components (e.g., suction, vent pumps, cardioplegia delivery).
- Expandable systems: Useful if you handle a range of cases (e.g., pediatric and adult).
User Interface and Workflow
- Touchscreen controls
- Customizable presets for different procedures
- Easy access to all system components
- Data integration with hospital EMR systems
Check for Integration with Other Systems
Modern machines may integrate with:
- Anesthesia monitors
- Electronic medical records (EMR)
- Perfusion data tracking software
Consider Portability and OR Fit
- Ensure the unit fits in your operating room layout.
- Portable or compact machines may be necessary for smaller ORs or hybrid suites.
Assess Manufacturer Support and Training
Choose a reputable manufacturer that provides:
- On-site training and certification
- 24/7 technical support
- Spare parts availability
- Software updates and compliance with local regulations
Set a Realistic Budget
- Basic systems: ~$100,000–$200,000
- Advanced systems with monitoring: ~$250,000–$500,000+
- Leasing/refurbished options may be available
