What is the function of an oxygen sensor in the ventilator?

The function of oxygen sensors in ventilators

1、Oxygen concentration monitoring

The oxygen sensor detects the oxygen concentration in the ventilator in real time. It ensures that the oxygen concentration is as required. This prevents breathing problems caused by too little or too much oxygen.

2、Oxygen flow control

Oxygen sensors work in conjunction with flow sensors. They precisely control the oxygen flow and stabilize the oxygen supply. This prevents breathing problems caused by flow fluctuations.

3、Oxygen Leakage Alarm

The oxygen sensor monitors the oxygen line. It can quickly detect oxygen leaks and sound an alarm. This alerts medical staff to take timely action to prevent serious consequences.

Improper use can lead to serious consequences such as respiratory failure

• Supplying too little oxygen leads to tissue hypoxia and respiratory failure.

• Excessive supply of oxygen leads to oxygen toxicity and damage to lung tissue.

• Oxygen leakage results in decreased concentration, rendering the ventilator useless and the patient unable to maintain respiration.

• Displacement of oxygen tubing, resulting in oxygen not being able to enter the body, causing failure of respiratory mechanical ventilation.

• Flow rate fluctuates too much, causing respiratory burden and leading to respiratory distress.

• Prolonged mechanical ventilation may lead to lung infection.

How could oxygen sensors improve safety?

• Monitoring oxygen concentration inside the ventilator

Oxygen sensor monitors the oxygen concentration in the ventilator in real time. If the concentration is detected to be too high or too low, it will immediately sound an alarm. This alerts medical staff to adjust ventilation parameters in time to avoid continuing to supply oxygen at an inappropriate concentration. This prevents possible respiratory problems or tissue damage.

• Working with sensors

At the same time, oxygen sensors work in conjunction with flow sensors. They continuously monitor the stability of the oxygen flow rate. If large fluctuations in the flow rate are detected, the sensors feed back control information to smooth out the oxygen flow. This prevents flow fluctuations from placing an additional burden on the patient's breathing, which can lead to respiratory distress.

• Oxygen line monitoring

In addition, the oxygen sensor can monitor the oxygen line in real time. If an oxygen leak is detected, it quickly sends out a brightly lit alarm. This prompts medical staff to immediately check the oxygen line and disconnect the oxygen source. This prevents accidents from escalating and oxygen leaks from causing ventilator failure.

How to correctly use oxygen sensors？

1、First of all, it is very important to choose the right type of oxygen sensor. Different measurement environments and accuracy requirements will affect the choice of model. At the same time, it is important to ensure that the selected product is of reliable quality.

2、Then, the installation location of the oxygen sensor also needs to be carefully considered. It is necessary to choose a reasonable location for detection, so that the monitoring is more accurate and reliable. If conditions permit, it is recommended to install multiple sensors for redundant monitoring.

3、In addition, routine maintenance is also essential. Sensors should be cleaned regularly to avoid contamination affecting performance. Also check that the power supply and wiring connections are working properly. If necessary, calibration is also an effective means to ensure accuracy.

4、Finally, set the alarm value and alarm mode of the sensor reasonably. Making a good response plan can enable problems to be responded to and dealt with in a timely manner. It should be linked with the equipment to automatically take corresponding measures when abnormalities are detected.
