Non-invasive Ventilator Classification and Precautions for Use

Non-invasive ventilators can be divided into single-level and bi-level ventilators.

Single level ventilators provide a constant pressure working mode when the patient inhales and exhales. This constant pressure supports the upper airway so that the patient's upper airway remains continuously open during sleep, avoiding collapse and reducing the occurrence of sleep apnea. Single level ventilators are mainly used for most patients with snoring and sleep apnea syndrome.

Bi-level ventilators provide two different pressures, providing a higher pressure to keep the airway open during inspiration and a lower pressure to avoid collapse of the airway during exhalation, forming two pressure levels working alternately to enable the patient's ventilation to improve, i.e. bi-level ST mode ventilators. It is not only suitable for patients with obstructive sleep apnea syndrome, but also for patients with chronic obstructive pulmonary disease.

The use of non-invasive ventilators is not just a matter of knowing mode selection and parameter adjustment, but the details in clinical application are often the key factors in the success or failure of treatment. However, in the actual clinical application, these details are ignored or there are some misconceptions about the use of the machine. If the misconceptions and details are not correctly understood and paid attention to, it may lead to the failure to achieve the therapeutic effect, and then accelerate the deterioration of the disease.

If you are using a ventilator for the first time, there is no need to panic if you are not used to it. When you are awake during the day, you can just wear the mask and feel it, and then connect it to the ventilator after you get used to it, and then lie back and relax after you turn on the ventilator and get used to the airflow of the ventilator a little bit, so you don't have to rush it.

As an important accessory to block the air dust and bacteria, the filter cotton must be replaced in time. If the filter cotton becomes dirty, its purification ability will be greatly reduced, bacteria may be blown along the respirator to the respiratory tract to cause infection.

The water in the water tank of the respirator wetter should be replaced daily and disinfected and cleaned regularly. If the scale is produced by long-term use, the respirator water tank can be cleaned with a special descaling agent.

Patients with cold nose obstruction, in this case it is recommended not to force to wear a respirator; some patients will be too lazy to use the respirator after drinking, but at this time should be worn, alcohol has a central inhibitory effect, will aggravate the apnea, wear a respirator will make the risk of reducing the chances.
