How does high pulmonary capillary wedge pressure indicate high left atrial pressure?
Wiki User
∙ 15y ago
There is little resistance between the pulmonary artery (where the catheter is placed in PCW) and the left atrium. This means that the pressure remains about constant.

How can pulmonary hypertension protect from pulmonary odema?
This precapillary vasoconstriction has been considered to protect the pulmonary capillary bed from excessive pressure increases in pulmonary venous hypertension and therefore to prevent fluid leak and edema formation (115, 135).
What is normal atrial blood pressure?
normal atrial BP is 120/80
Does the p wave in an ekg indicate atrial depolarization?
No it does not. Atrial repolarization is generally not visible on the telemetry strip because it happens at the same time as ventricular depolarization (QRS complex). The P wave represents atrial DEpolarization (and atrial systole). Atrial repolarization happens during atrial diastole (and ventricular systole).
Atrial natriuretic factor is secreted in response to?
High blood pressure. PS it is known as atrial natriuretic peptide.
Where are the baroreceptors situated within the body?
Arterial = aortic and carotid sinuses. There are also atrial, ventricular and pulmonary baroreceptors
When are the AV valves open?
when ventricular pressure becomes greater than atrial pressure
Will atrial natriuretic peptide lower blood pressure?
yes
Which heart valve is open under pressure?
When the atria contract, there is increase in pressure in the atrial chambers. So both bicuspid and tricuspid valves opened up. When both the ventricles contract, both the bicuspid and tricuspid valves get closed. This opens up the aortic and pulmonary valves.
Who are more likely to suffer from atrial fibrillation?
often occurs in people with various types of heart disease. Atrial fibrillation may also result from an inflammation of the heart's covering (pericarditis ), chest trauma or surgery, pulmonary disease, and certain medications
Which hormone released by the heart regulates blood pressure?
Anti Naturetic Hormone which functions in reduction of water in the body.
Atrial natriuretic peptide ANP helps to lower blood pressure and is secreted by the?
heart
What is atrial reflex?
Atrial reflex is also known as the Bainbridge reflex which is an increase in heart rate due to central venous pressure of the heart. The atrial reflex controls the heart rate more so in dogs than in humans or other primates.
