Elastic recoil pressure (or transpulmonary pressure) is the difference in pressure between the inside and outside of the alveoli (Pal and Ppl, respectively) that determines if it will move from that resting state. The greater that difference (i.e., the higher the transpulmonary pressure), the bigger the lung is.

The transpulmonary pressure gradient (TPG), defined by the difference between mean pulmonary arterial pressure (Ppa) and left atrial pressure (Pla; commonly estimated by pulmonary capillary wedge pressure: Ppcw) has been recommended for the detection of intrinsic pulmonary vascular disease in left-heart conditions associated with increased pulmonary ...

Transpulmonary pressure. keeps the lungs against the chest wall and is the difference between the intrapulmonary pressure and the intrapleural pressure. The Pressure within the lungs intraplumonary pressure is greater than outside the lungs intrapleural pressure. Boyle's Law.

How is transpulmonary pressure equal to the elastic recoil of the lung? I don't understand what you get when you substract pleural pressure from alveolar pressure. Also while I was reseaching this pneumothorax came up. It seems that elatic recoil of the lung is pushing one way and the chest wall is pushing one way.

Transpulmonary pressure. Transpulmonary pressure is the difference between the alveolar pressure and the intrapleural pressure in the lungs. During human ventilation, air flows because of pressure gradients. Ptp = Palv – Pip. Where Ptp is transpulmonary pressure, Palv is alveolar pressure, and Pip is intrapleural pressure.

in mechanics, ratio of the forceforce, commonly, a push or pull, more properly defined in physics as a quantity that changes the motion, size, or shape of a body. Force is a vector quantity, having both magnitude and direction.

In the linear model, the transpulmonary pressure gradient (TPG) is only a function of flow rate (Q) as shown in a), and is not affected by pulmonary capillary wedge pressure (Ppcw), as shown in b), whatever the pulmonary vascular resistance.

define transpulmonary pressure. transpulmonary pressure (or transalveolar pressure) is the pressure difference between the alveolar space and the pleural space. It is the pressure required to maintain alveolar inflation and is therefore sometimes referred to as alveolar distending pressure. PL (or Ptp) = Palv - Ppl. define transrespiratory pressure.

The force per unit surface area at any point in a gas or liquid. The pressure of a gas is proportional to temperature and density: at constant temperature, as the density is increased the pressure increases accordingly.

The transpulmonary pressure is the pressure jump across the alveolar wall (at least, that's what you wrote). The lung itself does not have the ability to expand or contract via elastic stress- that's driven by the diaphragm- so I'm not sure what 'elastic recoil' refers to.
