Which condition is the progressive long term loss of lung function?

Which condition is the progressive long term loss of lung function?

Emphysema is a long-term, progressive disease of the lungs that primarily causes shortness of breath due to over-inflation of the alveoli (air sacs in the lung). In people with emphysema, the lung tissue involved in the exchange of gases (oxygen and carbon dioxide) is impaired or destroyed.

Is the progressive loss of lung function that is commonly attributed to long term smoking?

Emphysema is a disease of the lungs that usually develops after many years of smoking. Along with asthma and chronic bronchitis, emphysema belongs to a group of lung diseases known as chronic obstructive pulmonary disease (COPD).

Which condition is the progressive long term loss of lung function usually due to smoking quizlet?

Emphysema

Which term describes the loss of consciousness that occurs when the body Cannot get the air it needs to function?

Which term means easy or normal breathing? Walking pneumonia is also known as mycoplasma pneumonia. Which term describes the loss of consciousness that occurs when the body cannot get the air it needs to function? In atelectasis, the lung fails to expand because there is a blockage of the air passages or pneumothorax.

Is an abnormal condition caused by dust in the lungs?

Pneumoconiosis – literally, “an abnormal condition of dust in the lungs.” A generic name for conditions where toxic particles become trapped in the lungs and cause symptoms and disability such a “black lung” or “miner’s lung” disease.

Is the loss of consciousness that occurs when the body Cannot get the oxygen it needs to function?

Cerebral hypoxia occurs when there is not enough oxygen getting to the brain. The brain needs a constant supply of oxygen and nutrients to function. Cerebral hypoxia affects the largest parts of the brain, called the cerebral hemispheres.

How accurate are finger oxygen meters?

Pulse oximeter accuracy is highest at saturations of 90-100%, intermediate at 80-90%, and lowest below 80%.

What are the 2 readings on a pulse oximeter?

Your “Normal” SpO2 Range According to the Mayo Clinic, normal pulse oximeter readings usually range from 95 to 100 percent. Values under 90 percent are considered low, and indicate the need for supplemental oxygen.

What is normal pi %?

The normal perfusion index (PI) ranges from 0.02% to 20% showing weak to strong pulse strength.

What if Pi is high in oximeter?

PI is calculated by dividing the pulsatile signal (AC) by the nonpulsatile signal (DC) times 100, and is expressed as a percent ranging from 0.02% to 20%. A higher PI value, therefore, indicates a stronger pulsatile signal and better peripheral circulation at the sensor site.

What is pi level?

Perfusion Index or PI is the ratio of the pulsatile blood flow to the non-pulsatile static blood flow in a patient’s peripheral tissue, such as finger tip, toe, or ear lobe. Perfusion index is normally monitored with pulse oximeters. PI is also a good indicator of the reliability of the pulse oximeter reading.

What is adequate perfusion?

Adequate perfusion is defined as adequate circulation of blood through organs and tissues, manifested by normal pulse, tissue color, level of consciousness and blood pressure.

What does a high perfusion index mean?

A higher perfusion index means greater blood flow to the finger and a lower perfusion index means lower blood flow to the finger. Your perfusion index may or may not change significantly in the morning or after exercise.
