Tactile fremitus is a palpable vibration felt over the chest wall that is produced by the transmission of sound waves from the trachea and larger bronchi to the chest wall. It is a valuable clinical sign that can be used to assess the patency of the airways and to detect the presence of consolidation or fluid in the lungs.
Tactile fremitus is best elicited by placing the ulnar aspect of the hand firmly against the chest wall and asking the patient to say “ninety-nine” or “one-one-one.” The vibrations produced by the patient’s voice will be transmitted to the examiner’s hand, and the examiner will feel a palpable thrill. The intensity of the tactile fremitus will vary depending on the underlying lung tissue. It will be increased over areas of consolidation or fluid, and it will be decreased or absent over areas of emphysema or atelectasis.
Tactile fremitus is a simple and inexpensive test that can provide valuable information about the condition of the lungs. It is a useful adjunct to auscultation and percussion, and it can help to identify patients who need further investigation.
1. Definition
Tactile fremitus is a valuable clinical sign that can be used to assess the patency of the airways and to detect the presence of consolidation or fluid in the lungs. It is a simple and inexpensive test that can provide valuable information about the condition of the lungs.
In order to check tactile fremitus, the examiner places the ulnar aspect of the hand firmly against the chest wall and asks the patient to say “ninety-nine” or “one-one-one.” The vibrations produced by the patient’s voice will be transmitted to the examiner’s hand, and the examiner will feel a palpable thrill. The intensity of the tactile fremitus will vary depending on the underlying lung tissue. It will be increased over areas of consolidation or fluid, and it will be decreased or absent over areas of emphysema or atelectasis.
Understanding the definition of tactile fremitus is essential for checking tactile fremitus correctly. The examiner needs to know what tactile fremitus is and how it is produced in order to be able to accurately assess the intensity of the tactile fremitus and to interpret the findings.
For example, if the examiner does not know that tactile fremitus is produced by the transmission of sound waves from the trachea and larger bronchi to the chest wall, they may not be able to correctly interpret the findings if the patient has a weak voice or if there is a lot of background noise.
By understanding the definition of tactile fremitus, the examiner can more accurately check tactile fremitus and use the findings to assess the condition of the lungs.
2. Technique
This technique is important because it allows the examiner to feel the vibrations produced by the patient’s voice as they travel through the chest wall. These vibrations are transmitted to the examiner’s hand through the ulnar aspect of the hand, which is the most sensitive part of the hand to vibrations.
By asking the patient to say “ninety-nine” or “one-one-one,” the examiner can standardize the intensity and pitch of the patient’s voice, which helps to ensure that the tactile fremitus is elicited consistently.
Understanding this technique is essential for checking tactile fremitus correctly. If the examiner does not use the correct technique, they may not be able to accurately assess the intensity of the tactile fremitus and may miss important clinical findings.
For example, if the examiner does not place the ulnar aspect of the hand firmly against the chest wall, they may not be able to feel the vibrations produced by the patient’s voice. This could lead to a false negative result, where the examiner incorrectly concludes that the tactile fremitus is decreased or absent.
By understanding the technique for checking tactile fremitus, the examiner can more accurately assess the condition of the lungs and identify patients who need further investigation.
3. Interpretation
The interpretation of tactile fremitus is an essential component of “how to check tactile fremitus” because it allows the examiner to assess the condition of the underlying lung tissue. By understanding the relationship between the intensity of tactile fremitus and the underlying lung tissue, the examiner can identify areas of consolidation, fluid, emphysema, or atelectasis.
For example, if the examiner finds an area of increased tactile fremitus, this may indicate the presence of consolidation or fluid in the underlying lung tissue. This could be caused by a number of conditions, such as pneumonia or pulmonary edema. Conversely, if the examiner finds an area of decreased or absent tactile fremitus, this may indicate the presence of emphysema or atelectasis. Emphysema is a condition in which the alveoli are damaged and lose their elasticity, while atelectasis is a condition in which the alveoli are collapsed.
By understanding the interpretation of tactile fremitus, the examiner can more accurately assess the condition of the lungs and identify patients who need further investigation.
4. Importance
Tactile fremitus is an important component of “how to check tactile fremitus” because it is a simple, inexpensive, and non-invasive test that can provide valuable information about the condition of the lungs. It is a valuable clinical sign that can be used to assess the patency of the airways and to detect the presence of consolidation or fluid in the lungs.
By understanding the importance of tactile fremitus, healthcare professionals can more effectively use this test to assess the condition of the lungs and to identify patients who need further investigation. For example, if a patient has decreased or absent tactile fremitus, this may indicate the presence of emphysema or atelectasis, and further investigation may be needed to confirm the diagnosis.
In conclusion, tactile fremitus is an important component of “how to check tactile fremitus” because it is a simple, inexpensive, and non-invasive test that can provide valuable information about the condition of the lungs. By understanding the importance of tactile fremitus, healthcare professionals can more effectively use this test to assess the condition of the lungs and to identify patients who need further investigation.
5. Limitations
Tactile fremitus is a valuable clinical sign that can be used to assess the condition of the lungs. However, it can be difficult to interpret in obese patients or in patients with thick chest walls. This is because the adipose tissue and thick chest wall can dampen the vibrations that are produced by the voice and transmitted to the chest wall.
-
Obesity
In obese patients, the adipose tissue can absorb the vibrations that are produced by the voice, making it difficult to feel the tactile fremitus. This can lead to a false negative result, where the examiner incorrectly concludes that the tactile fremitus is decreased or absent.
-
Thick chest wall
In patients with a thick chest wall, the vibrations that are produced by the voice may not be able to penetrate the chest wall, making it difficult to feel the tactile fremitus. This can also lead to a false negative result.
It is important to be aware of these limitations when checking tactile fremitus. If the examiner is unsure whether the tactile fremitus is decreased or absent due to obesity or a thick chest wall, they may need to use other methods to assess the condition of the lungs, such as auscultation or percussion.
