Normal Intrapleural Pressures among Indians

Intrapleural Pressures on the Contralateral Side in Pleurisy with Effusion

The intrapleural pressures on the contralateral side in pleurisy with effusion were within the normal range, the normal intrapleural pressures among Indians being ?14 to ?3 cm. of water during inspiration, ?10 to 0 cm. water during expiration, and the mean pressure ?12 to ?2 cm. water (Laha, 1946). Neither the amount nor the duration of effusion had any effect on the intrapleural pressures on t...

Oesophageal pressure measurements in ventilated preterm babies.

Oesophageal pressure measured with an air-filled, thin latex balloon on a 6 French gauge catheter can accurately measure intraoesophageal pressures in ventilated preterm babies. Intraoesophageal pressures and intrapleural pressures are equivalent. Less than 10% of the applied positive ventilator pressure is transmitted to the oesophageal balloon and the intrapleural catheter (intercostal drain)...

A simple analogue of lung mechanics.

A model of the chest and lungs can be easily constructed from a bottle of water, a balloon, a syringe, a rubber stopper, glass and rubber tubing, and clamps. The model is a more exact analogue of the body than the classic apparatus of Hering in two respects: 1) the pleurae and intrapleural fluid are represented by water rather than air, and 2) the subatmospheric "intrapleural" pressure is creat...

Intrapleural Pressures in Congestive Heart Failure

The values of intrapleural pressure before the removal of chest tube in non-complicated pulmonary lobectomies.

OBJECTIVES Digitalized chest drainage systems allow for quantification of air leak and measurement of intrapleural pressure. Little is known about the value of intrapleural pressure during the postoperative phase and its role in the recovering process after pulmonary resection. The objective of this investigation was to measure the values of pleural pressure immediately before the removal of ch...
