Pressure-volume curves of the respiratory system.
The quasi-static pressure-volume (P-V) curve of the respiratory system describes the mechanical behavior of the lungs and chest wall during inflation and deflation. To eliminate resistive and convective acceleration effects, the measurement of volume and pressure must be performed during short periods of apnea or during very slow flow. There are 3 main techniques for acquiring quasi-static P-V ...
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 کاملon translation of phatic communion and socio-cultural relationships between the characters of the novels
phatic communion is a cultural concept which differs across cultures. according to hofstede (2001), the u.s. tends to have individualistic culture; however, asian countries tend to have collectivistic cultures. these cultures view phatic communion differently. in individualistic cultures like u.s., phatic communion reflects speakers’ socio-cultural relationships in conversations. to see whether...
15 صفحه اولLeft 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 کاملApplication of continuous positive airway pressure to trace static pressure-volume curves of the respiratory system.
OBJECTIVE To evaluate a new technique for pressure-volume curve tracing. DESIGN Prospective experimental study. SETTING Animal research laboratory. SUBJECTS Six anesthetized rats. INTERVENTIONS Two pressure-volume curves were obtained by means of the super-syringe method (gold standard) and the continuous positive airway pressure (CPAP) method. For the CPAP method, the ventilator was sw...
