BACKGROUND It has been reported that deep breathing could reduce blood pressures (BP) in general. It is also known that BP is decreased during inhalation and increased during exhalation. Therefore, the measured BPs could be potentially different during deep breathing with different lengths of inhalation and exhalation. This study aimed to quantitatively investigate the effect of different respi...
OBJECTIVE Breathing exercises after cardiac surgery are often performed in a sitting position. It is unknown whether oxygenation would be better in the standing position. The aim of this study was to evaluate oxygenation and subjective breathing ability during sitting vs standing performance of deep breathing exercises on the second day after cardiac surgery. METHODS Patients undergoing coron...
abstract the balvard metamorphic assemblage (bma) crops out at the northeastern margin of the southeastern part of the sanandaj-sirjan zone (ssz) in contacting to the dehshir-baft ophiolitic mélange. this location prepared a special situation to resolve some of the complicated tectonic problems of this part of iran. petrology, micro-tectonics and satellite image investigation were carried out ...
The objective was to establish whether an intravascular volume increase leads to a heart rate (HR) increase without increased sympathetic tonus. HR changes at rest and at deep breathing (6/min - simulated increase of atrial filling pressure) were measured in patients after heart transplantation. Evaluation of dependency of HR changes on breathing depth was done through a new time series methodo...
BACKGROUND The 3-dimensional (3D) distances of specific points on the chest and abdominal wall are useful for assessing the characteristics of breathing movement. This study aimed to determine whether the 3D distances on the chest and abdominal wall during deep breathing (DB) could be estimated using a newly developed breathing movement-measuring device (BMMD). METHODS Breathing movement dist...
BACKGROUND Physical assessment of breathing is an important component of physical therapy evaluations. However, there are no standardized reference values of breathing movements available for use in clinical practice. The purpose of this study was to determine the 3-dimensional distances of observational points on the thorax and abdomen during breathing in healthy subjects and to assess the ef...
BACKGROUND Desflurane and sevoflurane have markedly different pungencies. The tested hypothesis was that patients breathing equivalent concentrations of desflurane or sevoflurane through a laryngeal mask airway (LMA) would have similar responses. METHODS After institutional review board approval and informed consent were obtained, 60 patients were enrolled and given intravenous midazolam (14 ...
Ankle exercises are commonly used to facilitate venous return in the lower extremity and to prevent deep vein thrombosis. Moreover, the respiratory cycle affects venous return. This study examined the effects of ankle exercise combined with deep breathing on the blood flow velocity in the femoral vein. Twenty healthy males (mean age 21.3 years), who had no medical history of lower extremity dis...
1. Hypoxia, induced by 7-12% oxygen breathing, produced vasodilatation in the intact or in the phenoxybenzamine and propranolol treated forearm of human volunteers when arterial blood POz decreased below 45 mmHg, or when deep forearm venous blood PO, decreased below 3540 mmHg. 2. Circulatory arrest of the forearm following alpha and beta adrenergic receptor blockade was followed by greater incr...
