overdistention

(ō′vĕr-dĭs-tĕn′shĭn)

Excessive stretching, insufflation, or inflation of an organ, e.g., of the lungs during mechanical ventilation or of the urinary bladder in bladder outlet obstruction.

As the name suggests, MB was thought to protect against overdistention of the RV.[7] The mechanical stretch and misarranged cardiomyocyte renders the insertion sites more vulnerable to arrhythmia generation.

Successful Ablation of Moderator Band-Originated Ventricular Tachycardia at Its Ventricle Insertion Sites

Although the use of NIMV strategies has not gained universal approval in this setting because of the increased transpulmonary pressure and the uncontrolled overdistention of the alveoli, the commonly advocated advantages include the preservation of airway defence mechanisms, the decreased need for sedation and improvements in gas exchange.

The uterine overdistention, cervical diseases, breakdown of maternal-fetal tolerance, decidual senescence, vascular disorders, infections, and stress are the major mechanisms of the disease implicated in spontaneous preterm labor, but probably there are still unknown factors included in this pathology [1].

Cytokines in Preterm Delivery: Proposal of a New Diagnostic Algorithm

Uterine overdistention in multiple gestations (and in polyhydramnios) has been implicated in preterm birth (3,6).

It was thought to be a structure protecting against overdistention of the RV, hence the name "moderator" [3].

Additionally, in ARDS, the presence of RVD (hemodynamic status) and not Pa[O.sub.2]/Fi[O.sub.2] ratio could be an indication for proning to unload the RV by recruiting collapsed alveoli without causing overdistention and reducing airway pressure and hypercapnia ("RV-protective" ventilation strategy) [77-79].

Acute Right Ventricular Dysfunction in Intensive Care Unit

(17) It is thought that the antecedent to preterm delivery in multiples is uterine overdistention. (18,19) Currently, there are no established therapies to reduce the risk of preterm delivery in higher order multiples.

Patient factors associated with the risk of spontaneous preterm birth

While normally the pericardium exerts a mild containing force that somewhat prevents overdistention of the cardiac chambers, in CP this extrinsic pressure is increased and most commonly transmitted uniformly to all cardiac chambers equalizing chamber pressures.

MR imaging of pericardial diseases

Pneumonia accompanied with pneumopericardium caused by anaerobic bacteria Staphylococci and Klebsiella have been described before.3 Moreover mechanical ventilation predisposed alveoli to both barotrauma and volutrauma which aggravated overdistention of the friable alveoli.

Cardiac tamponade due to pneumopericardium

This mode of ventilation provides small tidal volumes and high mean airway pressures that prevent both collapse and overdistention of the alveoli, a key goal in ARDS treatment (Chan, Stewart, & Mehta, 2007).

Complex care: ventilation management when brain injury and acute lung injury coexist

Additionally, because all PFC15 lungs presented rupture of alveolar septae due to overdistention, we decided to exclude the 15 mL/kg dose experiments.

Endobronchial perfluorocarbon reduces inflammatory activity before and after lung transplantation in an animal experimental model

The only complications were bradycardia, which responded to atropine, and overdistention of the lung if the tube was too large.
