Pressure-volume relationships in the lung during laparoscopy.
Pressure-volume relationships for the total respiratory system and for the lung were recorded in anaesthetized and paralysed patients, during deflation from an airway pressure of 3 kPa to FRC at a rate of 2 litre min-1. Pleural pressure was estimated by means of an oesophageal balloon. A group of nine female patients (mean age 32.7 yr) about to undergo laparoscopy were each studied in four succ...
متن کاملPressure-volume relationships in the interstitial spaces.
This paper will discuss the recent finding that the normal interstitial fluid pressure is negative rather than positive and will present a method for recording dynamic changes in interstitial fluid pressure. Especially important is the shape of the pressure-volume curve of the interstitial spaces. So long as the interstitial fluid pressure is negative, the interstitial fluid volume remains almo...
متن کاملLeft Ventricular Pressure-Volume Relationships
It has been shown in man that myocardial ischemia, whether precipitated by exercise or pacinginduced tachycardia, is associated with abnormalities of left ventricular end-diastolic pressure. There has been controversy as to whether this relationship is due to decreased myocardial compliance or to an increase in left ventricular volume as a manifestation of left ventricular failure. Simultaneous...
متن کاملAbdominal pressure during laparoscopy: effects of fentanyl.
BACKGROUND In patients breathing spontaneously during anaesthesia, expiration is active and opioids enhance this effect. The mechanical consequences are not well characterized. METHODS We studied 14 patients undergoing laparoscopy for minor gynaecological procedures, anaesthetized with isoflurane in nitrous oxide, and breathing spontaneously through a laryngeal mask airway. We made direct rec...
متن کاملPressure-volume relationships in right ventricle.
• Recently, we have reported on the pressure developed in the left ventricle when that chamber was made to contract under conditions closely approaching that of being isovolumic.' 2 More recently, the use of a latex balloon to change the amount of effort of the right ventricle yielded data on the pressure developed in the right ventricle at different volumes under nearly isovolumic conditions. ...
