Mechanical Ventilation

• Use of a machine to induce alternating inflation and deflation of the lungs with air
• Regulates Oxygen/CO2 levels in blood
• Volume and Pressure of Air forced into Lungs is controlled
• Has to meet varying demands of patient ventilation

Modes of Ventilation

• Volume control
• Pressure control
• CPAP/BIPAP
• Support Ventilation
• Combination Of Modes
• Intermittent mandatory Ventilation

Components of Ventilator System

• Compressed Gas Source
• Patient Breathing Circuit
• Mixer/Blender
• Hoses
• Optional monitoring
• O2
• Volume

Classification

• Driving Mechanism
• Pneumatic (Mark 7)
• Electronic (Siemens 900C)Function
• Respirators: Short time ventilator support
• Conventional Ventilators :long term, advance Support Portability
• Transport/battery backup Patients Adult Pediatric Or Neonatal
