Pressure support ventilation (PSV), also known as pressure support, is a spontaneous mode of ventilation. The patient initiates every breath and the ventilator delivers support with the preset pressure value. With support from the ventilator, the patient also regulates their own respiratory rate and tidal volume. [1]
Modes of mechanical ventilation are one of the most important aspects of the usage of mechanical ventilation.The mode refers to the method of inspiratory support. In general, mode selection is based on clinician familiarity and institutional preferences, since there is a paucity of evidence indicating that the mode affects clinical outcome.
Continuous spontaneous ventilation is any mode of mechanical ventilation where every breath is spontaneous (i.e., patient triggered and patient cycled). Spontaneous breathing is defined as the movement of gas in and out of the lungs that is produced in response to an individual's respiratory muscles.
Adaptive Support Ventilation is a positive pressure mode of mechanical ventilation that is closed-loop controlled. In this mode, the clinician enters patient ideal body weight and desired level of ventilation in percent of predicted alveolar ventilation and the ventilator then applies inspiratory pressures at a rate which leads to minimal work ...
Mechanical ventilation is often a life-saving intervention, but carries potential complications. A common complication of positive pressure ventilation stemming directly from the ventilator settings include volutrauma and barotrauma. [11] [12] Others include pneumothorax, subcutaneous emphysema, pneumomediastinum, and pneumoperitoneum.
The pressure-cycled ventilation includes pressure control ventilation and pressure support ventilation. Both methods offer a set inspiratory pressure. The tidal volume varies depending on the resistance and elastance of the respiratory system. Pressure-cycled ventilation can help alleviate symptoms in patients with acute respiratory distress ...
Pressure control (PC) is a mode of mechanical ventilation alone and a variable within other modes of mechanical ventilation. Pressure control is used to regulate pressures applied during mechanical ventilation. Air delivered into the patients lungs (breaths) are currently regulated by Volume Control or Pressure Control. In pressure controlled ...
