The plateau pressure is the pressure applied (in positive pressure ventilation) to the small airways and alveoli. It is believed that control of the plateau pressure is important, as excessive stretch of alveoli has been implicated as the cause of ventilator induced lung injury. The peak pressure is the pressure measured by the ventilator in the major airways, and it strongly reflects airways resistance. For example, in acute severe asthma, there is a large gradient between the peak pressure (high) and the plateau pressure (normal). In pressure controlled ventilation, the pressure limit is (usually) the plateau pressure due to the dispersion of gas in inspiration. In volume control, the pressure measured (the PAW) by the ventilator is the peak airway pressure, which is really the pressure at the level of the major airways. To know the real airway pressure, the plateau pressure which is applied at alveolar level, the volume breath must be made to simulate a pressure breath. An inspiratory hold (0.5 to 1 second) is applied, and the airway pressure, from the initial peak, drops down to a plateau. The hold represents a position of no flow.
Peak inspiratory pressure refers to the maximum pressure reached during inspiration, while plateau pressure refers to the pressure measured when there is no airflow in the lungs at the end of an inspiratory pause. Plateau pressure is a better indicator of lung distensibility and risk of overinflation compared to peak inspiratory pressure.
Plateau pressure is determined by the compliance of the lungs and chest wall, as well as the volume of air in the lungs at end-inspiration. It is affected by factors such as lung disease, obesity, and the presence of chest wall abnormalities. Monitoring plateau pressure is important in managing mechanical ventilation in critically ill patients to prevent lung injury.
Plateau pressure is the pressure in the lungs when no air is flowing, measured during a pause in mechanical ventilation. It reflects the distending pressure applied to the alveoli and is important in preventing lung injury during mechanical ventilation. High plateau pressure can indicate overdistention of the lungs and can lead to ventilator-induced lung injury.
What is a normal blood pressure listing?
Normal blood pressure in an adult would be 120/80
For a normal, healthy adult the normal blood pressure is 120/80
is it normal for blood pressure at 96 to be normal
Normal blood pressure is measured by two numbers that represent how much mercury is in your blood. A completely normal blood pressure reads: Below 120 / below 80.
NORMAL BLOOD PRESSURE
Blood pressure readings that are normal
Oil level and oil pressure are different. You don't need to have full oil to get normal pressure.
