Positioning

tilted up at 45 degrees if the patient can tolerate this. The head should rest on a pillow and the arms by their sides. The level of the jugular venous pressure (JVP) should only be commented on in this position as flatter or steeper angles lead to artificially elevated or reduced level respectively. Also, left ventricular failure leads to
pulmonary edema Pulmonary edema, also known as pulmonary congestion, is excessive liquid accumulation in the tissue and air spaces (usually alveoli) of the lungs. It leads to impaired gas exchange and may cause hypoxemia and respiratory failure. It is due to ...
which increases and may impede breathing if the patient is laid flat. Lighting should be adjusted so that it is not obscured by the examiner who will approach from the right hand side of the patient as is medical custom. The torso and neck should be fully exposed and access should be available to the legs.


Inspection

General Inspection: * Inspect the patient status whether he or she is comfortable at rest or obviously short of breath. * Inspect the neck for increased jugular venous pressure (JVP) or abnormal waves.250 cases in clinical medicine 3rd edition. R. R. Baliga * Any abnormal movements such as head bobbing. * There are specific signs associated with cardiac illness and abnormality however, during inspection any noticed cutaneous sign should be noted. Inspect the hands for: * Temperature – described as warm or cool, clammy or dry * Skin turgor for hydration * Janeway lesion *

. The apex beat is assessed for size, amplitude, location, impulse and duration. There are specific terms to describe the sensation such as tapping, heaving and thrusting. Often the apex beat is felt diffusely over a large area, in this case the most inferior and lateral position it can be felt in should be described as well as the location of the largest amplitude.
