Sleep apnea is quite a widespread disorder which influences breathing and is characterized by its interruptions. It is present in millions of people globally; they experience interrupted sleep and various health complications. Consequently, identifying and diagnosing sleep apnea is integral in the treatment process and that is where sleep apnea testing comes into the picture. This article shall borrow insights on an extensive understanding of sleep apnea testing with regard to its significance, procedure, and what the patient should expect. 

 What is Sleep Apnea? 

 The medical condition of sleep apnea is associated with a temporary suspension of breathing or minimize breathing episodes that occur at night. These disturbances can range from seconds to several minutes and it observed up to 30 or more times per hour. The most prevalent forms are OSA, CSA and complex SAS with OSA and CSA being the most frequent forms of sleep apnea. Of these, OSA is the most common and occurs when throat muscles are relaxed and close off the airway while asleep. CSA is different when the brain is itself unable to send out the appropriate signals to muscles responsible for breathing. 

 Sleep apnea testing: An analysis of its necessity. 

 A sleep apnea condition that is not identified or addressed can result to hazards such as high blood pressure, cardiovascular disease, stroke, diabetes and tiredness during the day. It can also lead to poor focus and even day dreaming and this could in turn lead to accidental instances. Therefore, sleep apnea testing to finalize the diagnosis and assess the severity to tailor the dependable course of treatment is recommended. 

 Different Forms of Sleep Apnea Examination 

 There are primarily two types of sleep apnea tests: In the case of sleep disorders, the most common diagnostic tools and tests are polysomnography (PSG) and home sleep apnea test (HSAT). 

 Polysomnography (PSG): This is the most comprehensive test for diagnosing sleep apnea and it also monitors the patient’s behaviors during slumber to provide results. An PSG is performed during night time in a sleep lab and measures brain waves, oxygen level in blood, heart rate, breathing, eye and leg movements. This entails affixing the electrodes at different parts of the body which is slightly uncomfortable though it enhances the data acquisition. PSG is the optimal method to diagnose SAs, particularly in the patients with complicated clinical scenario or when other types of SBDs are anticipated. 

 Home Sleep Apnea Testing (HSAT): For those who do not want to go out in their pajamas or just want to be at home in their own bed, HSAT is provided for. This is characterized by the use of simple equipment compared to PSG and captures less parameters in its study yet sufficient for diagnosing OSA. The use of HSAT is advised when the consumer is likely to have moderate to severe OSA and no other clinical conditions. It is less invasive to the target and easier to use hence preferred by many. 

 The steps of conducting a sleep apnea test 

 Before engagement in any treatment, the client has to visit a healthcare provider who will discuss the symptoms, medical history may perform a checkup. If the physician has reason to believe the patient suffers from sleep apnea, they will refer the patient to either a PSG or to an HSAT. 

  1. Preparation: Caffeine and alcohol are discouraged in the periods leading to the test since they disrupt a patient’s sleep. In the case of PSG, one should wear pajamas and any other essentials that one might require during an overnight stay in the sleep lab. 
  1. During the Test: 
  • Polysomnography: When a patient reaches the sleep lab, the technician wires the patient’s scalp, face, chest, and limbs with adhesive or elastic straps. These sensors continuously measure some physiological indices during the night. The patient is then encouraged to sleep as normally as possible Also, the defence and reassurance mechanisms are used by encouraging the patient to sleep as normally as possible. 
  • Home Sleep Apnea Testing: The patient gets a small box which is a monitoring device and is told to set it before going to bed. This is normally done on the finger, chest and under the nose where airflow, heartbeat and oxygen are aprised. Specific directives and sometimes a brief are given for correct assembly.
  1. Post-Test: Then the data is processed by a sleep specialist, though it is the patients themselves who take the test. In regard to PSG, the information analysis also consists of the evaluation of the recorded parameters to detect any deviations from normal breathing. For HSAT, the data is reviewed but is more concentrated on OSA signs and symptoms correspondingly. 
  1. Diagnosis and Treatment: Thereby, using the data obtained from the tests, the child is diagnosed. If a person has sleep apnea, there maybe ways to manage it that will be recommended by the doctor, these include; changes in his eating habits and sleeping position, using a Continuous Positive Airway Pressure (CPAP) machine, or special mouth appliances, surgery if the cause of the sleep apnea is related to anatomical abnormalities. The appropriateness of the choice depends on the severity of the pathologies and specific characteristics of the patient. 


 Sleep apnea testing remains a significant component of the diagnostic and therapeutic process of dealing with this condition that could be lethal. In the case of treatment too, while using polysomnography conducted in a sleep laboratory or through home sleep apnea testing, the first step that is strongly recommended is to acquire an accurate diagnosis. If you think you have APAP, talk to your doctor about your signs so that you can be referred to the most appropriate test. Nevertheless, it is important to consider the fact that early diagnosis and proper treatment will help minimize the health complications of sleep apnea and improve the quality of the night’s rest as well as one’s wellbeing.
