Oxygen or compressed air

Ventilators usually use both oxygen and compressed air as air sources. Specifically:

Oxygen:

• Effect: Provide the oxygen needed by the patient to maintain normal blood oxygen saturation.
• Pressure regulation: The working pressure of oxygen is usually adjusted to 0.4MPa (equivalent to 4 atmospheres of pressure), ensuring that the ventilator can provide a stable and sufficient oxygen supply.
• Source: Oxygen can come from the hospital’s central oxygen supply system, or use an oxygen cylinder to provide oxygen. When using an oxygen cylinder, the high-pressure oxygen in the oxygen cylinder needs to be adjusted to the pressure required by the ventilator through a pressure reducing valve.

Compressed Air:

• Effect: Provides the power source required for the ventilator to operate while mixing with oxygen to adjust the inhaled oxygen concentration (FiO₂).
• Pressure regulation: As a pressure air source, the air compression pump has a working pressure of 0.4MPa to ensure that the ventilator can work normally.
• Source: Compressed air is usually provided by air compressors, which are widely used in hospitals or medical institutions.

Summary:

The ventilator requires the use of oxygen and compressed air as the air source at the same time. Oxygen is used to provide the oxygen needed by the patient, and compressed air acts as a power source for the ventilator to operate and is mixed with oxygen to adjust the inhaled oxygen concentration. The pressure of both gases needs to be adjusted to the level required by the ventilator (typically 0.4MPa) to ensure that the ventilator works properly and provides effective breathing support.

Precautions for use:

1. Regular inspection: Before using the ventilator, check whether the pressure of oxygen and compressed air meets the requirements to ensure that the pipeline is intact and does not leak.
2. Parameter settings: Set appropriate ventilator parameters according to the specific situation of the patient and the doctor’s advice, such as inhaled oxygen concentration, peak inhalation pressure, positive end-expiration pressure, etc.
3. Monitoring and Adjustment: During use, the patient’s vital signs and the operation of the ventilator should be closely monitored. If there are any abnormalities, the settings should be adjusted in time or the doctor should be contacted.
4. Maintenance and Maintenance: Regularly clean and disinfect the ventilator and its accessories to maintain the equipmentNormal function and hygiene. Meanwhile, maintain the equipment as directed by the manufacturer to extend the service life of the equipment.
