Bipap / Bilevel Training Module Pop Quiz.

Explanation
The "S/T" in "BiPAP S/T" stands for "Spontaneous Timed." This refers to a mode of BiPAP ventilation where the machine delivers a set number of breaths per minute (timed), but also allows the patient to initiate breaths on their own (spontaneous). This mode is often used for patients who need assistance with breathing but can still breathe on their own to some extent.

Explanation
The Trigger Sensitivity setting makes inhaling easier or harder.

Explanation
When switching from CPAP to BiPAP remember that the EPAP setting should be the pressure at which obstructive apneas were eliminated, while also ensuring proper PS with the IPAP.

Explanation
During a BiPAP titration, increasing the IPAP pressure would be an appropriate response to snoring and hypopneas. Snoring is a common symptom of obstructive sleep apnea and increasing the IPAP pressure can help to open the airway and reduce snoring. Hypopneas, which are partial blockages of the airway, can also be addressed by increasing the IPAP pressure to improve airflow and prevent further obstruction. However, obstructive apneas and mixed apneas may require different interventions, such as adjusting the EPAP pressure or using a different treatment modality altogether.

Explanation
The biggest difference between the S and S/T modes of BiPAP is that S/T mode requires a backup rate. This means that in S/T mode, the machine will automatically deliver a set number of breaths per minute, even if the patient does not initiate a breath on their own. This feature is useful for patients who have difficulty breathing on their own or have weak respiratory muscles. In contrast, the S mode does not have a backup rate and relies solely on the patient's own breathing efforts.
