PCM stations Flashcards
When is 02 necessary?
pO2< 60mmHg OR spO2< 90mmHg
What %O2 is 1L/min ?
24%
how much %O2 do you add for each 1L/min?
4%
When is a venturi mask used?
in patients that are hypercapnic with moderate hypoxemia
-especially in obstructive diseases
What is normal forced expiratory flow?
385 L/min
What does the curve look like on restrictive disorders?
narrow curve
-due to LOSS of elasticity
What does the curve look like on obstructive disorders?
scooped out curve
-due to air trapping by LOSS of recoil
how is COPD diagnosed?
bronchodilator response
-positive test if improvement PFTs by 12% or 200cc
what is a normal HR?
60-100 bpm
-brady and tachycardia are on either ends of that
how long should the PR interval be?
- 2, first degree block
- if progressive, second degree
- if no association between p wave and QRS complex, third degree block
QRS complex, how long should it be?
< 0.12
What does QT prolongation increase our risk for?
torsades de pointes
what is a normal axis look like?
Lead 1 is up, AVF up
Let axis deviation
1 is up, F is down
Right axis deviation

In the asthma action plan, what is the nebulizer treatment?
- saline-albuterol soln
- nose must be clear; direct patient to blow nose before treatment
- increase depth of breaths over time; direct patient to take shallow breaths, increasing with each dose of treatment
What is the most accurate measurement of oxygen saturation ?
