An review of non-invasive respiratory support for nursing students
Let’s be honest . . .

Ventilation can be a hard issue. I have stated before, that the RT (respiratory therapist) should be your nice buddy at the medical ground. Understanding the various modes of air flow and that is pleasant for a given affected person or sickness manner may be difficult.

This episode is designed to provide you an overview of the differences between CPAP and BiPAP so that you will be able to walk into a room and experience cozy with how your affected person is ventilating.

CPAP vs BiPAP
First of all, let’s outline what these phrases stand for:

CPAP – Continuous Positive Airway Pressure

BiPAP – Bilevel Positive Airway Pressure

It’s additionally essential to mention right here that both CPAP and BiPAP are NONinvasive modes of air flow . . . Which simply approach that we are not required to insert a tube (endotracheal tube for mechanical air flow). The patient sincerely requires a snug (very cushty) fitting face masks or nasal pillow that allows you to be on this therapy.

Cpap and bipap settings for nurses

Continuous vs Bilevel
The major distinction to keep in mind among these is that CPAP is turning in a hard and fast stress CONTINUOUSLY . . . It by no means modifications. It doesn’t rely how rapid the patient breaths, whether they are taking a breath, or if they forestall breathing . . . It’s going to just maintain pumping along at the same stress.

Bilevel alternatively is tons extra sophisticated. BiPAP will supply a DIFFERENT strain relying on whether the patient is taking a breath or exhaling.

These two strain differences are called IPAP and EPAP.

IPAP – Inspiratory Positive Airway Pressure

EPAP – Expiratory Positive Airway Pressure

This is critical for nurses and nursing college students to apprehend due to the fact this is the KEY difference between those cures and is the inspiration for his or her uses.

Uses for CPAP
Because CPAP handiest promises one pressure setting it is essential to remember that it helps satisfactory in situations of hypoxemia because it will resource with oxygenation.

CPAP will do the following:

↑O2
↓ Work of breathing
↑ Intrathoracic Pressure so that it will ↓ preload thereby ↓ cardiac workload
Due to those effects of CPAP, it may be useful in conditions of sleep apnea and CHF exacerbation.

The most effective actual placing for CPAP that the nurse desires to hold in thoughts is the initial stress putting . . . Measured in cmH2O.

Remember . . . CPAP is spontaneous . . . Which means the affected person does not receive any ventilatory guide.

Uses for BiPAP
Due to the important thing difference between CPAP and BiPAP ( one stress vs pressures) , BiPAP is a first rate tool for ventilation (removal of CO2) in conditions like COPD exacerbation or different conditions where the affected person desires air flow assist.

Settings for BiPAP written with the aid of the physician will look like this:

Bipap 10/5 rate of 12 FiO2 of 60%

Notice the 2 pressures (IPAP vs EPAP). The difference among these numbers is known as PRESSURE SUPPORT.

In the order above PS is five . . . IPAP – EPAP or 10-five.

Notice also that the physician has ordered a RATE. This is a massive distinction among BiPAP and CPAP. With BiPAP, a specific price is programmed within the system and whether or no longer the patient is respiration, the gadget will deliver the programmed strain at the set charge.

Also, notice the order has a hard and fast FiO2 . . . This is the % of O2 to be introduced. Normal room air has a FiO2 of approximately 21%. The FiO2 could be titrated to preserve the affected person’s SpO2 (pulse ox) or SaO2 (blood gas) at or above ninety one%.

If the affected person keeps to have trouble preserving suitable SpO2 or SaO2 . . . The FiO2 may be adjusted.

If CO2 levels are high then IPAP and EPAP may be adjusted for that reason.

As Pressure Support increases (the difference among IPAP and EPAP) the lungs can be capable of amplify more to allow expanded air flow (clearing of CO2).

SIMV vs AC
The aim of both SIMV and AC ventilator modes is to make sure right air flow/gasoline alternate for our sufferers. The fundamental difference has to do with the tidal quantity and the way/while it’s miles bipap machine price brought. This idea is discussed inside the episode at the side of a number of the common vent settings like PEEP, Pressure Support, Tidal Volume, and FiO2.

Conclusion
As I referred to above . . . We’ve RTs and Practitioners for a motive. . . . This may come to be very complex right away. However, it is VITAL that you recognize the fundamental settings and variations between CPAP and BiPAP.
