Homework #7 Question 9). State the purpose, uses, operation, calibration, and maintenance for colorimeters (include a block diagram/schematic).

10). State the purpose, uses, operation, and maintenance for a flame photometer ( include a block diagram/schematic).

11). State the purpose, uses, operation, and maintenance for spectrophotometers (include block diagram/schematic).

12). State the purposes, uses, operation, and maintenance for blood cell counters (include block diagram).

13). State the purposes, uses, and maintenance for pH/blood gas analyzers (include a diagram and description of a pH glass electrode).

14). State the purpose, uses, operation, and operation for chromatographs (include the different types).

15). State the purpose, uses, and maintenance of autoanalyzers (include system block diagram).

Problems 1). Refer to Figure 16-4b. Given V1 = +1.5mV with reference cuvetter and V1 = +35mV with reference and sample cuvettes, R2 = R3 = 2.4 k ohm, calculate the voltage read on the meter display for both condition of V1.

2). A nurse reports that a colorimeter that was previously working is now giving very low transmittance reading for all blood samples, which portion(s) of the device would you check first?

3). A medical technologist reports that the Coulter counter model S in the clinical lab gives correct RBC, WBC, Hct, and Hgb readings but incorrect MCV, MCH, and MCHC readings. What checkout procedure would you use to identify the trouble source?

4). A nurse in the neonatal nursery cannot obtain accurate readings with an isolette oxygen monitor. Which protion(s) of the device would you check first?

5). A medical technologist reports that a pH meter in the clinical lab has an output that wanders about an apparently correct pH value, what part of the device should probably be replaced?

Part 1: Valsalva maneuver Follow the procedures below. Save all data and make notes on experimental observations and questions asked.

Place some gel on your wrist and obtain a signal for arterial blood flow.

Observe the signal. Perform a Valsalva maneuver, which is a forceful exhalation against a closed glottis. The increased pressure that develops within the thorax decreases venous return and increases heart rate.

Use a watch and record the change in heart rate over 10 seconds (deliverable).

Occlude blood flow by pressing your finger on the artery inside your elbow. Observe and record the resulting signal (deliverable).

Part 2: Heart Valve Motion Detection Position over the mitral valve (about 5 cm under left nipple between the ribs via the intercostal muscles).

Listen to the motion of the mitral valve.

Move the transducer so it is over a rib, then between ribs. What happens?

Why do you suppose this happens (deliverable)? Part 3: Measuring Infusion Pump/Gravity Feed Flow Fill cup with fluid (i.e., water, milk, soda, etc.)

Feed tubing through infusion pump and set the pump to flow at a velocity of your choosing. (If you are using gravity feed bag on an IV rack, fill the bag with distilled water and clamp off flow with tube clamp until you are ready to measure.)

Apply acoustic gel to the transducer and place in a fixed position over tubing.

Point in various directions to detect the best fluid flow sound.

Listen to the motion of the fluid. How does this differ from the artery sounds? Is the sound smooth or pulsed? What would account for this (deliverables)? **********************************************************
