Experimental infusion of TNFa has been shown to cause ARDS and increased concentration of cytokines in the lungs of the patients with ARDS has been described in both early and late phase of lung injury.

The immune response to resistive breathing To the Editors: The excellent review by VASSILAKOPOULOS et al. [1] discusses in detail the immune response to resistive breathing. The authors report the systemic effects of resis-tive breathing (cytokines in plasma), as well as the effects of resistive loads on the respiratory muscles (diaphragm).

Whole-body exercise also induces increase of cytokines: effects on cytokines are based on the intensity and duration of the physical exercise [29]. After a marathon race, TNF-alpha and IL-1beta levels increase twofold and IL-6 levels increase up to 100-fold [32].

Guanylyl Cyclase Activation Reverses Resistive Breathing

Rationale: Inspiratory resistive breathing (RB), encountered in obstructive lung diseases, induces lung injury. Soluble Guanylyl Cyclase (sGC)/cGMP pathway is downregulated in chronic and acute animal models of RB such as asthma, COPD and in endotoxin-induced acute lung injury.

Airways Clearance Techniques in Cystic Fibrosis: Physiology

The work of breathing overcomes two main pr oblems the elastic recoil of the lungs and chest wall, and the airway resistance to gas fl ow. The total work of breathing is the sum of the elastic and resistive work and may be related to lung volume or breathing frequency (Fig 5).

resistive breathing (Vassilakopoulos et al 1999, 2004). Airway resistance and the work of breathing are typically increased in patients with severe COPD, especially during acute exacerbations of the disease (AECOPD) (Barbera et al 1997; Ramirez-Sarmiento et al 2002). Systemic infl ammation is known to increase during AECOPD (Malo et al 2002).

MAPKs and NF-κB differentially regulate cytokine expression

Resistive breathing induces cyto-kine upregulation in the diaphragm, a response that is quite immediate (within 1 h) and time dependent (55), and results in elevated levels of circulating cytokines in humans (58, 60). This early response, before any inflammatory cell influx in the diaphragm (61), suggests that these cytokines might serve

When applied, PEEP influences both the elastic and resistive properties of the lungs (Figure 1). The elastic properties of the lungs can be appreciated from the pressure volume curve. The PV curve extending from the residual volume (RV) to the total lung capacity (TLC) has a sigmoidal shape [22] (Figure 2).
