Abstract:
Hospital sound has been well documented through acoustic measurement and the classification of its adverse effects on patients and nurses. However, little consideration has been given to how the perception of these unavoidable soundscapes can be improved. For instance, does a better understanding of the variety of sounds improve patients' feeling? This paper begins to answer this and documents a pilot questionnaire-based study looking at the effects and potential benefits of sound source information (SSI) on patients' subjective reactions to a ward soundscape. The study was carried out from July to September 2011 with 31 patients in a cardiothoracic ward. Although strong inferences were not made, it was found that this simple intervention created a 21-26% positive change perception (p<0.05). The paper discusses the results in relation to nursing practice, concluding that SSI could be beneficial in helping patients to feel more comfortable.

01:15Heart Sounds
Auscultation is the process of listening to these internal body sounds using a stethoscope. The heart produces four types of sounds, but only two—S1 and S2—can usually be heard with a stethoscope.
S1, also known as the "lub" sound, is caused by the closure of atrioventricular (A-V) valves at the...

Normal Heart Sounds
S1 (First Heart Sound)-
S1 is made by the closure of the mitral and tricuspid valves (atrioventricular valves), marking the beginning of systole.
S2 (Second Heart Sound)-
S2 is made by the closure of the aortic and pulmonic valves (semilunar valves), marking the end of the systole.

Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...

Objectives and Importance:
The primary goal of respiratory assessment is to evaluate patients at early risk of clinical deterioration. Since respiratory distress often precedes other signs of declining health, breathing patterns and sounds become a...
