The question "What is HST CPAP?" is unclear. To provide a helpful answer, let's break it down into possible interpretations:
It seems that "HST" refers to a Home Sleep Apnea Test and the user is asking how that relates to CPAP therapy. Therefore, let’s rephrase the question: "How are Home Sleep Apnea Tests (HSTs) and CPAP therapy related?"
HSTs (Home Sleep Apnea Tests) are often used before CPAP (Continuous Positive Airway Pressure) therapy to diagnose sleep apnea. CPAP is a common treatment for sleep apnea, but a diagnosis is needed first. An HST is a convenient way to get that diagnosis.
Understanding the Relationship Between HSTs and CPAP
Here's a breakdown of how HSTs and CPAP therapy are connected:
-
Diagnosis of Sleep Apnea: According to the provided reference, an HST is "used to diagnose only sleep apnea". This is its primary role. It's a simplified sleep study conducted in the comfort of your home.
-
What an HST Measures: The test monitors key indicators during sleep, including:
- Breathing patterns
- Blood oxygen levels
- Breathing effort
-
CPAP as a Treatment: If the HST results indicate sleep apnea, a doctor will likely prescribe CPAP therapy. CPAP uses a machine to deliver continuous airflow through a mask, keeping your airways open during sleep.
-
HST vs. Lab Sleep Study: It's important to remember that an HST is not as comprehensive as a sleep study performed in a lab. HSTs are best suited for diagnosing sleep apnea but may not identify other sleep disorders. The reference states, "Unlike an overnight sleep study, which provides a more thorough assessment of sleep issues, an HST is used to diagnose only sleep apnea."
In Summary:
An HST helps determine if you need CPAP therapy by diagnosing sleep apnea. It's the first step in many cases.
