Bipap / Bilevel Training Module Pop Quiz.

1. What does the "S/T" mean in "BiPAP S/T"?

Spontaneous Timed

Super Timed

Special Trigger

Seconds Timed

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.

2. The Trigger Sensitivity setting makes what easier or harder?

Inhaling

Exhaling

Rise Time

Tidal Volume

The Trigger Sensitivity setting makes inhaling easier or harder.

Explanation

The Trigger Sensitivity setting makes inhaling easier or harder.

3. What is the biggest difference between the S and S/T modes of BiPAP?

S/T requires a backup rate

Trigger and Cycle sensitivity settings

Different IPAP and EPAP pressures

Pressure Support

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.

4. A patient is on CPAP, and once the pressure is increased to 12cmH20 obstructive apneas are no longer seen, but hypopneas persist until a pressure of 15cmH20, at which time the patient is placed on BiPAP.What should be the starting BiPAP pressure?

IPAP 16 / EPAP 12

IPAP 8 / EPAP 4

IPAP 15 / EPAP 10

IPAP 19 / EPAP 15

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

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.

5. During a BiPAP titration what would be an appropriate reason to increase the IPAP pressure? (Select all that apply)

Snoring

Hypopneas

Obstructive Apneas

Mixed Apneas

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.
