Blood-Gas and Hemodynamic Responses
Blood-gas (Pao2) and hemodynamic responses to the inhalation of oxygen were studied in 60 patients with acute myocardial infarction. Patients who were not in heart failure on admission and did not develop signs of heart failure with n the next 5 days achieved the same Pa02 level while breathing 100% oxygen as did patients without acute myocardial infarction. Patients with pulmonary edema or car...
متن کاملPhysiological Modeling of Responses to Upper Versus Lower Lobe Lung Volume Reduction in Homogeneous Emphysema
RATIONALE In clinical trials, homogeneous emphysema patients have responded well to upper lobe volume reduction but not lower lobe volume reduction. MATERIALS/METHODS To understand the physiological basis for this observation, a computer model was developed to simulate the effects of upper and lower lobe lung volume reduction on RV/TLC and lung recoil in homogeneous emphysema. RESULTS Patie...
متن کاملPhysiological and Statistical Approaches to Modeling of Synaptic Responses
Synaptic function centers on the physiological behavior of individual and combined synaptic sites, defined at the anatomical level as a unit consisting of a single postsynaptic density and presynaptic release region. However, multiple synaptic sites are usually activated together in a physiological response, even between two individual neurons. These multiple sites may be either grouped togethe...
متن کاملHemodynamic Consequences of Induced Changes in Blood Volume
• The acute effects of changes in blood volume on cardiac performance have been investigated intensively in the past in order to determine the relationship between filling pressure and cardiac output. The influence of sustained changes in blood volume on the entire circulation is, however, less well known. Yet an exploration of a possible interaction between the blood volume on the one hand and...
متن کاملAngiotensin II Type 1 Receptors and Systemic Hemodynamic and Renal Responses to Stress and Altered Blood Volume in Conscious Rabbits
We examined how systemic blockade of type 1 angiotensin (AT(1)-) receptors affects reflex control of the circulation and the kidney. In conscious rabbits, the effects of candesartan on responses of systemic and renal hemodynamics and renal excretory function to acute hypoxia, mild hemorrhage, and plasma volume expansion were tested. Candesartan reduced resting mean arterial pressure (MAP, -8 ± ...
