Miscellaneous for Midterm exam Flashcards
What vent setting is used to fight atelectasis?
PEEP
Compliance formula =
Change in volume
_______________
Change in Pressure
ECMO pump is set on free mode, what does this mean?
The pump is not paying attention to anything.
ECMO pump is set on Stand Alone mode, what does this mean?
The pump is servoregulated by safety mechanisms / parameters.
IRV
Inspiratory Reserve Volume
Amount of air that you can still breathe in if you needed to.
TV
Tidal Volume = (6 - 8 mL/kg)
Normal volume in/out during a normal respiration.
ERV
Expiratory Reserve Volume
Amount of air that you can still breathe OUT if you needed to.
RV
Residual Volume
Amount of air you have left in the lungs after a maximal expiration. (Air not able to breathe out)
IC
Inspiratory Capacity
VT + IRV
FRC
Functional Recidual Capacity
RV + ERV
VC
Vital Capacity = Maximum amount of gas that we can expire after a maximal expiration.
IRV + VT + ERV
TLC
Total Lung Capacity
Mnemonic used to remember my lung volumes ?

How could an increase in PEEP compromise ECMO function ?
↑ PEEP = ↑ Oxygenation, but also ↑ Intrathoracic pressure
which leads to ↑ pressure of the heart specially the RA which would therefore compromise VENOUS DARINAGE.
Vent Settings for an Adult ?
FiO2 PIP PEEP VT R
FiO2: 60% PIP: 15 PEEP: 1 -3 VT: 6 - 8 R: 12 - 15
Vent Settings for an Neonate ?
FiO2 PIP PEEP VT R
FiO2: 60% PIP: 20 PEEP: 1 -3 VT: 8 - 10 R: 20
Blood flows through the hollow fibers of the dialyzer, and a cleansing fluid , known as a dialysate solution, flows in the opposite direction. This configuration maximizes the removal of wastes. Throughout this process, the waste molecules move from a higher concentration in the blood to a lower concentration in the dialysate.
CRRT
This type of CRRT removes fluid without the need for replacement fluids. This can help prevent or treat fluid overload in cases when waste products don’t need to be removed, or the pH levels don’t need to be corrected. This method doesn’t use a blood pump the way other systems do– it’s driven instead by the patients’ own blood pressure; Arterial to Venous. Apparently it doesn’t work well to clear BUN or creatinine. Karen the CVVH goddess says that it doesn’t get used much anymore.
Slow Continuous Ultrafiltration (SCUF)
This type of CRRT removes large volumes of fluids and waste from the patient. It then uses replacement fluids (also known as a substitution solution), which are devoid of toxins, to maintain electrolyte and acid base balance.
Continuous Venovenous Hemofiltration (CVVH)
Initially developed for the management of hemodynamically unstable patients with acute renal failure, It is now is also used for management of fluid overload and acid-base disturbances resulting from conditions such as acute pulmonary edema, congestive heart failure, septic shock, and oliguric states in which pharmacologic or parenteral nutrition therapy necessitates administration of large volumes of fluids.
