Study Notes
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.
