Plateau Pressure | Overview, Calculation, and Normal Values

What is plateau pressure? This video provides an overview of this topic, including its important in patients who are receiving mechanical ventilatory support.
💥Plateau Pressure [Full Guide] ➜ ➜ ➜ bit.ly/3zmqXpv
➡️ Plateau Pressure
Plateau pressure is the pressure in the lungs during mechanical ventilation that can be measured by performing an inspiratory pause at the end of inspiration. It is important because it can help to determine the amount of pressure needed to keep the lungs inflated in the absence of airflow.
➡️ Normal Values
The normal value for plateau pressure is ≤ 30 cmH2O. However, the normal range for plateau pressure is 25-30 cmH2O.
➡️ What Causes an Increased Plateau Pressure?
Increased plateau pressures can result from conditions that cause lung stiffness and decreased lung compliance. Some examples include pulmonary fibrosis and acute respiratory distress syndrome (ARDS).
➡️ How to Measure Plateau Pressure on the Ventilator
In order to measure plateau pressure, the practitioner who is operating the ventilator must use the “inspiratory pause” control after a breath has been delivered but before exhalation.
➡️ How to Calculate Plateau Pressure
Plateau pressure can be measured by performing an inspiratory hold on the mechanical ventilator. However, it can also be calculated with the following formula:
Plateau pressure = (tidal volume / static compliance) + PEEP
This means that you must know the patient’s exhaled tidal volume, static compliance, and level of PEEP in order to calculate the plateau pressure.
➡️ How are Peak Pressure and Plateau Pressure Related?
Peak inspiratory pressure (PIP) is the highest pressure that occurs in the lungs during the inspiratory phase of breathing. It represents the amount of pressure needed to overcome airway resistance and chest wall compliance in order to deliver a breath.
➡️ Rules of Thumb
Peak pressure: The pressure generated by the ventilator that is required to overcome airway and alveolar resistance. Plateau pressure: The pressure in the lungs after a tidal volume breath has been delivered. Normal Pplat and increased PIP: A normal plateau pressure with an increased peak pressure indicates an increased airway resistance. Increased Pplat and increased PIP: An increased plateau and peak pressure indicates that the patient has an issue with lung compliance.
➡️ What is Driving Pressure?
Driving pressure in mechanical ventilation is measured by subtracting the positive-end expiratory pressure (PEEP) from the plateau pressure (Pplat).
Driving pressure = Pplat - PEEP
➡️ What is an Inspiratory Pause in Mechanical Ventilation?
An inspiratory pause is a control mechanism on the ventilator that allows practitioners to measure a patient’s plateau pressure.

I had no idea. Thank you!

[@adamdiakowsky4026]

A very insightful and informative video and I'm not a doctor or a nurse.

I guess the driving pressure is affected/changed by pt's O2 saturations, since peep is involved! So, I guess it is safe to say that before calculating driving pressure and Vt for "a" DP, "NOT" the Pt's IBW, we have to first find out what the O2 sats are in order to set the right peep and Fio2, before we can actually calculate an acceptable Vt for that driving pressure according to the lungs' stiffness or compliance?! So, that means, that Vt not only depends on setting that person's IBW VT as a normal lung at that weight, "BUT", also depends on the "stiffness or elastance" of those lungs since we have to open them with PEEP, which affects DP that we can calculate and use for better ventilation. In summary; I think, first start with Vt on IBW, then calculate Vt with DP according to Lung Compliance! ( HM!!!! pretty sneaky!!!!!! ha!!??) Am I right? Not sure!

Is it useless to measure plateau pressure on pressure control since the pressure is getting set?

[@tomcruise9317]

Sir what is a normal platue pressure for us without ventilation what dose it tell ...is it intra alveolar pressure at inspiratory pause or trans pulmonary which is intraalveolar minus intraplural pressure

[@greensahuaro2834]

Since we don't know the person's Static Cl on first time on ventilator 'cause we don't know the status of his/her lungs. I guess it's safe to say that we can start with a Vt bases on IBW "THEN" calculate Static Cl, plateau, and Driving Pressure to finally get the right Vt and ventilating pressures? And then do the changes needed, do abg's and confirm?

[@ClaraSalazarAlamillo]

Plateau pressure is exhaled VT/ PIP-PEEP
