Platelet count (Plt)

What does #2 measure?

-Platelet count

-The number of platelets (thrombocytes) in your blood, which are essential for blood clotting and controlling bleeding

What does #3 measure?

-Hematocrit

-The percentage of red blood cells (RBCs) in the total volume of blood

What is Hct?

3x Hgb

What is the normal range for Hct?

-White Blood Cell Count

-Number of WBC in a microliter of blood

What is WBC?

4500 - 11000 /µL (4.5 - 11)

What is the normal range for WBC?

Infection

When would WBC be elevated?

What value is bradycardia?

60-99 beats per minute

What value is NSR (normal sinus rhythm)?

>100 beats per minute

What value is sinus tachycardia (ST)?

>2 FB (finger breaths)

What value do you want MO (mouth opening)

>6 cm (3 fingers)

What value do you want TMD (thyromental distance)?

Full range of motion. Pt can move head up/down, side/side without limitation or pain.

What is FROM? What are you looking for?

Class 1. Full visualization of soft palate.

What is the Mallampati score (MP)? Why?

Class 2. Complete visualization of the uvula.

What is the Mallampati score (MP)? Why?

Class 3. Visualization of only base of the uvula.

What is the Mallampati score (MP)? Why?

Class 4. Soft palate is not visible at all.

What is the Mallampati score (MP)? Why?
