==Overview==
==Overview==
Persons with symptoms of pneumonia need medical evaluation. [[Physical examination]] by a health care provider may reveal [[fever]] or sometimes [[hypothermia|low body temperature]], an [[tachypnea|increased respiratory rate]], [[hypotension|low blood pressure]], a [[tachycardia|fast heart rate]], or a low [[oxygen saturation]], which is the amount of oxygen in the blood as indicated by either [[pulse oximetry]] or [[arterial blood gas|blood gas analysis]]. People who are struggling to breathe, who are confused, or who have [[cyanosis]] (blue-tinged skin) require immediate attention.

[[Auscultation]] findings include lack of normal breath sounds, the presence of crackling sounds ([[rales]]), or increased loudness of whispered speech (whispered pectoriloquy) with areas of the lung that are stiff and full of fluid, called consolidation. Vital signs are useful in determining the severity of illness and have predictive values. However, a high degree of suspicion should be kept in elderly as the presentation could be subtle in them.


Listening to the lungs with a [[stethoscope]] ([[auscultation]]) can reveal several things. A lack of normal breath sounds, the presence of crackling sounds ([[rales]]), or increased loudness of whispered speech (whispered pectoriloquy) can identify areas of the lung that are stiff and full of fluid, called "consolidation." The examiner may also feel the way the chest expands ([[palpation]]) and tap the chest wall ([[Percussion (medicine)|percussion]]) to further localize consolidation. The examiner may also palpate for increased vibration of the chest when speaking (tactile fremitus).<ref name=metlay>Metlay JP, Kapoor WN, Fine MJ.

==Physical Examination==
The physical examination, though not very sensitive and specific in diagnosis of community acquired pneumonia, helps in determining the severity of illness and ruling out other differentials. Vital signs are useful in determining the severity of illness and have predictive values. However, a high degree of suspicion should be kept in elderly as the presentation could be subtle in them.

Overview

Physical examination may reveal fever or sometimes low body temperature, an increased respiratory rate, low blood pressure, a fast heart rate, or a low oxygen saturation, which is the amount of oxygen in the blood as indicated by either pulse oximetry or blood gas analysis. Patients who have difficulty breathing, who are confused, or who have cyanosis (blue-tinged skin) require immediate attention. Auscultation findings include lack of normal breath sounds, the presence of crackling sounds (rales), or increased loudness of whispered speech (whispered pectoriloquy) with areas of the lung that are stiff and full of fluid, called consolidation. Vital signs are useful in determining the severity of illness and have predictive values. However, a high degree of suspicion should be kept in elderly as the presentation could be subtle in them.
