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.

What in peak inspiratory pressure?
The maximum pressure exerted against the patients airway during the breath.
What is normal plateau pressure?
Less than 30CMH2o
When was Negative pressure ventilator created?
Negative pressure ventilator was created in 1928.
What is a pressure ventilator?
It is designed to deliver air at a set pressure
The peak pressure on a ventilator reads 40 cm h20what is the equivalent pressure in mm hg?
the peak pressure on a ventilator reads 40 cm h20 what is the equivalent pressure in mm hg?
What are the 2 types of sensitivity in a mechanical ventilator?
A mechanical breath delivered by the ventilator can be initiated either through a detected change in the flow in the circuit, or a detected negative pressure (so flow trigger or pressure trigger)
Is the iron lung still in use today?
A negative pressure ventilator, often referred to as an iron lung can be defined as a form of medical ventilator medical that enables a person to breathe when normal muscle control has been lost or the work of breathing exceeds the person's ability. The iron lung was replaced by respirators and nebulizers.
What is the difference between normal ventilation and minute ventilation?
Normal ventilation means the patient receives a normal pressure or volume of gas while inspiring and also while expiring. Minute ventilation means the ventilator makes sure that the patient inspires and expires the particular minute volume set for the patient. For example if it is a 70kg patient . He needs a minute volume of 7L/min. the ventilator makes sure that the person inspires and expires 7L/min.

What are the signs that positive pressure ventilation has been effective and may be discontinued?
Positive pressure ventilation is the use of life sustaining systems to help individuals that are showing respiratory distress. The signs that positive pressure ventilation has been successful are breathing over the ventilator and blood gas labs that are in normal ranges.
What are the strategies to improve oxygenation?
The open lung approach is based on pressure-targeted ventilator strategies.
How positive pressure ventilation effect fi02?
positive pressue ventilation is usually provided by a mechanical ventilator. A blend of oxygen and air coming out of the ventilator. The FiO2 is set on the ventilator. The person gets the FiO2 set on the ventilator.The manual positive pressure ventilation is by resuscitating with a self inflating bag usually provided with oxygen. FiO2 is fractional inspired oxygen and does not change with positive pressure ventilation or negative pressure ventilation. Manual bagging FiO2 may be changing according to supply of oxygen, inhalation (speed and volume) and frequency of bagging.
