I. Several modes of ventilator
1. Pressure-supported ventilation
When a patient spontaneously inhales through a ventilator, he or she receives additional airflow from an on-demand valve set on the ventilator and receives positive pressure support in the airway.
2. Two-Phase Positive Airway Pressure Ventilation (BIPAP)
BIPAP is a pressure/time cycling mode of ventilation, commonly known as the "universal mode". This is through the software program set two different levels of CPAP, namely, P1 and P2 and its execution time Tl and T2, the patient can be in the set time with two different levels of CPAP for spontaneous respiration, the application of the BIPAP mode than the application of PAP to meet the patient's oxygen
3, airway pressure open ventilation
In the endotracheal pressure belt for the patient to let the pressure of the patient in a state of continuous temporary release of pressure to self ventilation
The patient in the endotracheal pressure band Continuous temporary release of pressure in the state of spontaneous breathing, the patient spontaneously inhaled the high-pressure segment, the ventilator supply of high-flow gases to the breathing ring to maintain roughly a certain level of CPAP, maintaining a higher lung capacity than the human body in the atmospheric pressure of spontaneous respiration, in order to assist in breathing, temporarily lower CPAP At this time, through the natural adaptation of the lungs can be passively expired gas and remove carbon dioxide.
Two, non-invasive ventilator and non-invasive ventilator have differences
1, invasive ventilator for tracheal intubation, tracheotomy mechanical ventilation for apnea, severe respiratory failure, severe pneumonia and other patients with a certain degree of traumatic, inconvenient to use, commonly used pressure-controlled and volume-controlled two modes of ventilation volume is guaranteed, sputum is easy to remove, the patient rationing comparison
2 , non-invasive ventilator is mainly connected through the mouthpiece, nasal mask, easy to use, often pressure-controlled ventilation, expectoration is difficult, should cooperate with the patient. Mainly used for chronic obstructive pulmonary disease, type respiratory failure, sleep apnea syndrome and other diseases patients.
With the continuous improvement of our current hospital level, medical equipment is also constantly updated, the ventilator is in the clinic is a very commonly used medical equipment, this equipment is an effective means of replacing the patient's voluntary gas function, this equipment is mainly used for a variety of reasons resulting in respiratory failure, anesthesia respiratory management during major surgery, and so on.
