Sleep Apnea
People living with undiagnosed sleeping disorder, medically known as obstructive sleep apnea (OSA), can suffer various adverse effects of the condition such as increased risk of high blood pressure, diabetes, heart attacks, brain strokes and motor car driving accidents.
“There are more than 120 million adults with OSA in India. Children are also at high risk. A majority of the cases are undiagnosed and remain untreated. Current research has shown that OSA is a potentially life threatening with adverse effects if not treated .
WHAT ARE THE WARNING SIGNS OF OSA ?
- If patient is having symptoms associated with lung diseases
- For routine physical examination
- To monitor how effective your treatment is if you have a lung disease, such as asthma
- To assess how well your lungs are working before you have surgery .This test can be performed on the OPD basis.
The respiratory technician explains the entire procedure to the patient. For this test, patient sits in front of a machine and be fitted with a mouthpiece. It is important that the mouthpiece fits snugly so that all the air you breathe goes into the machine. You’ll also wear a nose clip to keep you from breathing air out through your nose. Patient will be instructed to inhale and exhale in different ways. He/she will be watched carefully during the procedure for dizziness, trouble breathing, or other problems. A bronchodilator may be given after certain tests. The tests will then be repeated several minutes later, after the bronchodilator has taken effect
It’s important that you don’t eat heavy meal before testing. A full stomach can prevent your lungs from inhaling fully.
PFTS ARE USUALLY SAFE FOR MOST PEOPLE. THE RISKS OF THIS PROCEDURE MAY INCLUDE:
- Dizziness during the tests
- Feeling short of breath
- Coughing
- Asthma attack brought on by deep inhalation
