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.

Alveolar collapse can be prevented by applying continuous positive end-expiratory pressure and tidal volume should be decreased to limit pulmonary overdistention.

EFFECTS OF PRESSURE-CONTROLLED AND VOLUME-CONTROLLED VENTILATION ON HEMODYNAMIC AND RESPIRATORY PARAMETERS IN PATIENTS DURING LAPAROSCOPIC CHOLECYSTECTOMY

17) It is thought that the antecedent to preterm delivery in multiples is uterine overdistention.

Patient factors associated with the risk of spontaneous preterm birth

sup][8] In a later animal study involving a large pleural effusion, when the P[sub]aw stress index >1, the CT scan showed significant amounts of alveolar collapse in the dependent lung area and no obvious overdistention in the nondependent lung area.

Physiological Correlation of Airway Pressure and Transpulmonary Pressure Stress Index on Respiratory Mechanics in Acute Respiratory Failure

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

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

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

Insufflation anaesthesia and the Kelly-Mott machine

Emphysema patients characteristically present with overdistention, which produces the "barrel-chest" deformity.

Chronic bronchitis and emphysema

If possible, the bed partner/roommate should be questioned about the patient's quantity and quality of sleep,s Accurate determination of the cause of sleep problems and consideration of associated medical conditions are important since, as an example, treatment with hypnotics may worsen breathing problems such as obstructive sleep apnea, cause ataxia during the night that leads to falls, or contribute to bladder overdistention in patients with conditions that lead to urinary retention.

Nocturnal awakenings: a case study with decision points

Gastric overdistention and ileus are contributing factors to aspiration and VAP; however, the use of the OG tube is not enough and frequent auscultation of bowel sounds and monitoring of gastric residuals will alert nurses to the presence of an ileus.

Interventions by critical care nurses reduce VAP

3) Protect the bladder against overdistention (expansion) with an indwelling Foley catheter.

Proper care can tame troubles

Avoid uterine overdistention by using gravity feed rather than pump-delivered saline for input and output.
