NUR 317 - Cardiac Exam Study Guide Define the following terms. Describe patient symptoms and conditions that could cause alterations in: Cardiac Output Volume of blood flowing through systemic or pulmonary circuit expressed in liters per min Normal= 5 L/min (resting adult) HRXSV= CO Factors: preload‚ afterload‚ myocardial contractility‚ heart rate As heart rate increases‚ this allows less time for diastole and the heart often cannot fill adequately. Therefore‚ a very rapid heart will often have

arterial wall 3. Describe how the sympathetic and parasympathetic nervous systems work together to regulate the heart rate. a. The sympathetic and parasympathetic are two branches of the autonomic nervous system. Both supply nerve impulses to the heart. The sympathetic (fight or flight)‚ becomes more active when needed. Stimulation will increase the heart rate and force of contractions.

response time related to a stimulus using the Labscribe software. For the second part of the lab‚ electromyograms will be triggered and recorded in order to study the Achilles and patellar stretch reflex and the reflex arc. Also‚ to understand nerve conduction velocity‚ EMG‚ and motor control. 2. The objectives of the first part of this lab is to observe and measure the reaction time to visual cues and compare this to the reaction time to auditory cues‚ to determine which stimulus would cause a longer

Describe the Cardiac Cycle The Cardiac cycle is a description of the activities that take place in the period from the start of one heart the next. The conducting system autonomically controls the heart beat impulses it is also called the cardiac conduction system or the nodal system. It is made up of six main components the sinoatrial node (SA-Node)‚ internodal paths‚ atrioventricular node (AV-Node)‚ atrioventricular bundle (AV bundle) or bundle of His‚ bundle branches and Purkinje fibres. Contractile

Age Related Changes that Occur in the Cardiovascular System Age Related Changes that Occur in the Cardiovascular System In the normal conduction of the heart the electrical impulse starts in the SA node‚ also called the pacemaker of the heart. The electrical impulse travels through the right atrium and through the Bachmann’s bundle into the left atrium. This stimulates the atria to contract. Next the signal travel to the AV node. The AV node slightly delays the signal. This delay is needed

Sensing the World – Basic Principles * Bottom-up processing suggests that we attend to or perceive elements by starting with the smaller‚ more fine details of that element and then building upward until we have a solid representation of it in our minds. * Top-Down Processing states that we form perceptions (or focus our attention) by starting with the larger concept or idea (it can even be the concept or idea of an object) and

As a matter of fact‚ some of us really gets irritated when experiencing such heat in our body due to uneven temperature. Particularly these days

incorporating in the pore. In addition‚ when we are speaking about electronic conductivity‚ it should be mentioned that electrons do not have an absolute monopoly on electrical conduction in solids. In literature still possible to meet a great uncertainty as to whether typical measurements allow researcher to conclude that conduction in a given m is due predominately to ions or to electrons. Many researchers have assumed that some of the MOFS can be treated as wide band gap semiconductors but other scientists

Basic cooking principle CONDUCTION Conduction occurs in two ways: 1. When heat moves directly from one item to another part of item example‚ from the top of the range to a soup pot placed on it‚ from the pot to the broth inside‚ and from the broth to the solid food items in it. 2. When heat moves from one part of something to an adjacent part of the same item for example‚ from the exterior of a roast to the interior‚ or from a sauté pan to its handle. Different materials conduct heat at different
