OT Ventilator

Components of an OT Ventilator
Airway Circuit:
This includes the endotracheal tube (ET tube) or laryngeal mask airway (LMA) that is inserted into the patient's airway to ensure that air can be delivered to the lungs. The breathing circuit is connected to the ventilator to transport air in and out of the lungs.

Control Unit:
The control unit is where settings like tidal volume, inspiratory pressure, and respiratory rate are adjusted. These settings are tailored based on the patient's needs and the type of surgery being performed.

Oxygen Source:
OT ventilators are typically connected to an oxygen supply system that delivers high-concentration oxygen to the patient during surgery. The ventilator mixes oxygen with air to create the appropriate mixture.

Blower or Compressor:
The blower or compressor is responsible for delivering air and maintaining consistent airflow during mechanical ventilation. Some ventilators use pneumatic systems, while others use electric compressors.

Exhalation Valve:
An important safety feature, the exhalation valve allows the patient to exhale CO2 and other waste gases during the ventilation cycle.

Monitors:
OT ventilators are equipped with real-time monitors that display parameters such as airway pressure, exhaled volume, and oxygen levels. These monitors help the anesthesiologist adjust settings to meet the patient’s needs.

Alarm System:
Alarm systems are integral in ensuring patient safety. If the ventilator detects any issue (like low oxygen levels, high airway pressure, or apnea), it triggers an alarm to alert the medical team.
