The immediate steps to be taken in the event of a ventilator malfunction are as follows:
1. Immediately switch to manual ventilation:
In the event of a ventilator malfunction, healthcare workers should immediately switch to manual ventilation. Manual ventilation can be performed by mask or endotracheal tube to ensure that the patient is able to maintain normal oxygen supply and carbon dioxide elimination.
2. Check ventilator connections and air supply system:
The healthcare worker should check the ventilator connections to ensure that the ventilator is connected to the patient's airway. It is also important to check that the endotracheal tube or mask is securely connected to the ventilator to prevent air leakage.
3. Check the oxygen supply:
Ensure that the oxygen supply system is working properly and that the oxygen concentration meets the patient's needs. If the ventilator uses oxygen cylinders to supply oxygen, replace the cylinders in time.
4. Check the ventilator display and alarm system:
Carefully observe the ventilator's display for fault messages. At the same time, check the alarm system of the ventilator to ensure that the abnormal state of the ventilator is detected in time.
5. Prepare a backup ventilator:
In a clinical setting, one or more backup ventilators are usually available. If the primary ventilator fails, the healthcare provider should quickly transfer the patient to the backup ventilator to safeguard the patient's respiratory function.
6. Call technical support or repair personnel:
If a healthcare worker is unable to resolve a ventilator malfunction, he or she should immediately call medical device technical support or repair personnel. They usually have the expertise and skills to quickly localize and fix ventilator malfunctions.
7. Maintain monitoring and observation:
Even when manually ventilating or switching to a backup ventilator, healthcare workers need to closely monitor the patient's vital signs, including heart rate, blood pressure, and oxygen saturation. Observe the patient's breathing at all times to ensure that the patient's oxygen supply and ventilation are good.
