The sudden impact on the thorax causes an increase in intrathoracic pressure.

During respiratory inspiration, the negative intrathoracic pressure causes increased blood return into the right side of the heart.

Increased compliance of the lungs increases the intrathoracic pressure.

This is because the intrathoracic pressure becomes more negative relative to atmospheric pressure.

Simply breathing in brings some additional blood into the lung because of the negative intrathoracic pressure required for inspiration.

Lower impedance indicates greater the intrathoracic fluid volume and blood flow.

Endoscopic resection of intrathoracic tumors: experience with and long-term results for 26 patients.

Many paramedics can perform needle thoracentesis to relieve intrathoracic pressure.

During inspiration, the chest wall expands and causes the intrathoracic pressure to become more negative (think of a vacuum).

Recording of the ambient pH in the intrathoracic colon was carried out simultaneously.

It is usually caused by an intrathoracic radiopaque mass that touches the border of the heart or aorta.

However, the decrease in intrathoracic pressure also expands the compliant pulmonary vasculature.

During expiration, the chest wall collapses and decreases the negative intrathoracic pressure (compared to inspiration).

Five-year survival and patterns of intrathoracic recurrence.

Tension pneumothorax Through increased intrathoracic pressure, bloodflow to the heart is prevented (venous return).

Waddell's nosebleed was due to the Valsalva maneuver, or an abrupt increase in intrathoracic pressure.

For longer surgical procedures (intraabdominal or intrathoracic surgery), 10% of dextrose should be used to avoid excessive fluid administration.

Intrathoracic cancers such as mesothelioma.

Intrathoracic supernumerary ribs are extremely rare.

High cervical (C2) or intrathoracic lesion.

During inhalation intrathoracic pressure decreases.

Intrathoracic neoplasms other than bronchogenic carcinoma.

Sub-glenoid, sub clavicular, and, very rarely, intrathoracic or retroperitoneal dislocations may occur.

Inhalation leads to drop in intrathoracic pressure, which increases the capacity of pulmonary circulation, thereby prolonging ejection time.

Definition of disease involvement of intrathoracic tissues by CT will often dictate more aggressive therapy than would otherwise have been administered.
