help on parts d and e

D. Your patient is wearing a 31% venturi mask and has a stable soo. When his mea and he removes his mask to eat, his Spo, drops to 84%. How can this problem List your goal for this patient and make recommendations on how to about your recommendations. E. when calibrating a polarographic oxygen analyzer, you balance the analyzer to con room air without difficulty. When you then expose the probe to 100% oxygen, the analyzer reads 82%. 1. What is the most likely cause of the problem? 2. What other cause(s) need to be ruled out? Lab Three: High Flow 02 Systems 222202000002200022

Answer 1

Answer D

Goals for maintaining oxygen saturation while eating:

1. To maintain adequate oxygenation of vital tissues and organs by supplying oxygen through nasal cannula while eating.

2. To restore and maintain blood oxygen levels, namely peripheral capillary oxygen saturation (SpO₂), between 92–100%.

Recommendations:

We can alleviate this problem by supplying oxygen via nasal cannula. The standard nasal cannula delivers an FiO₂ of 24-44% at supply flows ranging from 1-8 liters per minute (LPM). As the patient was already on 31% oxygen delivery via venturi mask, this work can effectively be done by nasal cannula without causing hypoxemia or hindrance while eating.

Answer E

Polarographic oxygen analyzer is an electrochemical device used to analyze the proportion of oxygen molecules in respiratory care systems.

1. New calibration is required when, the measured O2 percentage in 100% & O2 range is 82%.

2. a. Lean mixture causes low voltage, since there is an oxygen excess.

b. Air calibration is not recommended unless the Sensor can be exposed to a known source of clean air. Hospital room air is often enriched with excess oxygen.
