Do you really know about Ventilators?
Hospital Ventilator Machine is divided into two types: invasive and non-invasive. Generally speaking, an invasive ventilator requires tracheal intubation. Non-invasive ventilator generally uses a mask or nasal mask. Many family members of patients will not understand why it is necessary to use an invasive ventilator without a non-invasive ventilator, and tracheal intubation makes the patient very painful. No matter which type of ventilator has advantages and disadvantages. Depending on the situation, we need to choose a ventilator. Although the non-invasive ventilator is convenient to use and the patient has less pain, it has less support for breathing and can be used in a less severe situation. If the situation is more serious, the patient will have difficulty breathing and wear a mask and breathing support. , The patient will be very uncomfortable, leading to worsening of the condition. Like if the patient is unconscious, an invasive ventilator must be used. Because non-invasive breathing will cover the patient's mouth or nose or mouth and nose if vomiting occurs in a coma and the patient does not know that removing the mask will cause a critical situation. Therefore, non-invasive ventilator is not recommended for patients with coma and respiratory failure. In the case of using an invasive ventilator, it can protect the airway. Even after vomiting, it can't suck into the lungs, reducing some troubles in later treatment. Therefore, according to different conditions and patient conditions, the use conditions of the two ventilators will also be different.
Hospital Ventilator Machine
As a Wholesale Mechanical Ventilator Machine, share with you the trigger of the ventilator.
Purpose of ventilator trigger:
When the patient inhales, the ventilator's air is called: inhalation trigger
When the patient exhales, the ventilator can stop breathing in time. It is called: exhalation trigger
Ventilator trigger principle:
The patient's spontaneous breathing will cause slight changes in air pressure or flow rate in the ventilator circuit;
The breathing machine senses this change and gives or stops aspirating;
Too sensitive will cause false triggering of the ventilator, insensitivity will cause no trigger or invalid trigger
The trigger of the ventilator:
Pressure trigger: easy to understand and highly fault-tolerant. Like non-invasive ventilators, pressure trigger mode is often used. Because of the non-invasive ventilator is leaking, the interference to the flow trigger is relatively large in the leaking state.
Traffic triggering: more sensitive and relatively low fault tolerance.
Breath Trigger: Breath Trigger is also a flow trigger. Inhale is switched to exhale according to the change of flow rate.
Exhalation triggers autonomous ventilation modes for CPAP, SPONT and SIMV
There is no difference in efficacy, whether it is pressure-triggered or flow-triggered.
