Oximetry Questions and Graded Answers, 100% Guarantee
Pulse Oximetry - - Non invasive infrared light
- Attached to finger, earlobe, nose, forehead
- Measures oxygen saturation of hemoglobin
- Normal: 94-99%
What % of SpO2 do you need O2 therapy? - < 94%
Severe tissue hypoxia - < 85%
Factors affecting accuracy of Pulse oximetry - - Peripheral blood flow must be adequate
- CPR
- Vasoconstrictors
- Cold
- Client movement
- Nail polish and acrylic nails
- Edema
- Carbon monoxide poisoning (false high)
- Anemia
Pulse oximetry procedure - 1. Select appropriate sensor
2. Explain purpose to patient
3. Instruct pt. to breath normally
4. Select appropriate site
5. Remove nail polish or acrylic nail
, 6. Attach sensor probe, connect it to oximeter
7. Watch for pulse-sensing bar fluctuation
8. Set alarm limits
9. Read saturation on monitor and document findings
TCDB - - Turn, Cough, and Deep Breathing
- mobilizes secretions and improves oxygenation
- expands lungs -> expands alveoli -> decreases risks of atelectasis (alveolar collapse)
- promoting effective cough -> pushes secretions and mucus in the airways upward
- Prevents mucous plugs, atelectasis, hypoxemia, and pneumonia
TCDB Nursing Implications - - Educate and encourage patient
- Collaborate with RT
- Splint abdominal/chest incision with pillow (if surgical patient)
- Assess lung sounds before, after, and q4 hrs
- Adequate pain control
- Assist pt. to Fowler's position
Assisting pt. to Fowler's position - - Have client place hands along lower border of rib
cage to promote diaphragmatic breathing
- Splint incisions with pillow if needed
- Ask pt. to inhale slowly through the nose. Hold breath 1-3 seconds.
- Have pt. exhale slowly through mouth. Repeat 3-5 times Q 2-3 hrs.
- If abnormal lung sounds or sputum, have patient cough 2-3 times after inhalation
Chest physiotherapy (goal) - - Remove bronchial secretions
- Improve ventilation
- Increase the efficiency of respiratory muscles
