Ventilator Components and Ventilation Modes

Ventilator Components

• Control Unit: The brain of the ventilator, responsible for controlling and monitoring the ventilation process.
• Breathing Circuit: The tubing and connections that carry gas to and from the patient.
• Sensors: Monitor patient parameters such as pressure, flow, and oxygen saturation.
• Valves: Control the flow of gas into and out of the lungs.
• Blower or Pump: Creates the pressure needed to deliver gas to the patient.

Ventilation Modes

• Volume Control: Delivers a set volume of gas with each breath.
• Pressure Control: Delivers a set pressure with each breath, allowing the patient to determine the volume.
• Pressure Support: Provides additional pressure to support the patient's spontaneous breathing.
• Assist/Control: Combines volume control with pressure support.

Ventilation Parameters

• Tidal Volume (Vt): The volume of gas delivered with each breath.
• Respiratory Rate (RR): The number of breaths per minute.
• Inspiratory Pressure (IP): The pressure applied during inhalation.
• Positive End-Expiratory Pressure (PEEP): The pressure applied at the end of exhalation.
• Fraction of Inspired Oxygen (FiO2): The percentage of oxygen in the inhaled gas.

Ventilator Settings

• Adult settings: Typically 500-700ml Vt, 12-20 breaths/min RR, and 5-15 cmH2O IP.
• Pediatric settings: Vt and RR adjusted based on age and weight.
• Neonatal settings: Vt and RR adjusted based on birth weight and gestational age.

Alarms and Safety Features

• High Pressure Alarm: Alerts the operator to excessive pressure in the breathing circuit.
• Low Pressure Alarm: Alerts the operator to insufficient pressure in the breathing circuit.
• Apnea Alarm: Alerts the operator to a prolonged period without patient breathing.
• Oxygen Sensor: Monitors the oxygen level in the inhaled gas.
