24
Q

How do you calculate the percentage of gas being administered when 2 or 3 gases are being administered?

A

% of gas = (L) of the gas / Total amount of (L) administered x 100

25
Q

What is the percent of oxygen in Air

A

21%

26
Q

When you calculate flow of O2 in flow of medical air you must

A

first calculate the percentage of O2 out of the flow of medical air (21% of (x) L of air ) then proceed with other calculation.

27
Q

Given a full cylinder contains 660L O2 @ 2000psi, How long can O2 flows of 2L/min be maintained if the bourdon pressure gauge reads 1000psi?

A

165 min

28
Q

** General formula for E-cylinder calculation

A

Duration of Flow = Oxygen Tank CONVERSION FACTOR

x Remaining Tank Pressure (psi) / Continuous Flow Rate (L/min).

29
Q

What is the CONVERSION FACTOR OF Esize tank

A

0.28

30
Q

Estimated Blood Volume (EBV), these values are calculated based upon: SWA; the formula is
EBV?

A

Age, Sex, Weight; EBV = body wt (kg) x average blood volume (ABV) (ml/kg)

32
Q

How do you calculated EBV

A

Average blood volume x weight (kg)

33
Q

How do you calculate ABL (Allowable Blood loss)

A

ABL = ((Original Hct - Final Hct)/ Original Hct) x EBV

34

A

4 2 1
4* for first 10kg
2* for 2nd 10kg
1 for remainder kg

A

reproducibility of the measurement

37
Q

Precision is the

A

reproducibility

38
Q

The precision of a date set is improved
