With the advancement of the times, people have developed big in many aspects, such as aviation, transportation, military, medical, and so on. In the medical industry, people not only improve medical technology but also invented many medical devices. Among the myriad of devices, have one machine is used to provide life-sustaining oxygen to patients who are unable to breathe on their own. This kind of machine is called a medical ventilator.
If you have family members or friends using a ventilator, you should know the following:
- What is the definition of a ventilator?
A ventilator is a breathing-supporting machine that is used primarily in hospitals or rehabilitation facilities. Medical problems or conditions that make it difficult for a patient to breathe require the use of a ventilator to assist in the breathing process.
- How does the ventilator work?
The ventilator helps inhale oxygen into the patient’s lungs and removes carbon dioxide, a potentially toxic waste gas. It is used for life support but does not treat illness or medical conditions.
- Who needs a ventilator?
(1) Patients who have not breathed after the heart or breathing has stopped (provided it is possible to recover);
(2) Patients with weakened chest wall muscles or transverse diaphragm due to neurasthenia (such as GB syndrome or polio) or muscle weakness (such as muscular dystrophy);
(3) Patients with difficulty in air exhalation due to paralysis in the air tube cause carbon dioxide retention (eg severe asthma attacks or chronic bronchitis);
(4) For patients with impaired air passages (such as comatose patients, mechanical obstruction during surgery or obstruction of the trachea), artificial airways (tracheal catheters) are placed, which are narrower than the natural airways and increase the work of breathing. Mechanical ventilators again help to reduce this extra work;
(5) For patients with pulmonary water submergence (pulmonary edema) or secretions (such as pneumonia) who are unable to maintain adequate oxygenation levels, mechanical ventilators can help maintain positive pulmonary inflation. The ventilator can also deliver high concentrations of oxygen.
It is also common to use a ventilator when an average person is anesthetized during a general surgery. After completing the surgery or medical procedure, the patient may not even know that they are connected to the ventilator.
- Eat through a ventilator.
The snorkel will prevent the patient from eating normally, so different tubes that provide nutrition can be inserted into their veins. Patients with long-term ventilation may need to insert the feeding tube directly into the nasal cavity or mouth, or through a hole in the stomach.
- The ventilator limits movement.
On the ventilator, the patient’s activities and movements are significantly limited. Although they can sit on a bed or chair, they have limited mobility.
- Does the breathing opportunity pain?
It is usually little or no pain on the ventilator.
