1. Oropharyngeal/ Nasal Pharyngeal Suctioning: Assess: S&S oƒ upper and lower airway ob-
struction
:S&S associated with hypoxia and hypercapnia (decrease Spo2, increase pulse and BP, increase resps, anxiety, decrease concentrati
lethargy,dizziness, cyanosis)
:ƒluid status, lack oƒ humidity, COPD, changes in LOC, decrease cough gagreƒlex
:examine sputum, encourage client to cough, semi-ƒowlers position, use pulse oximeter, place towel on clients chest, Suction kit:
open with aseptic (clean) technique,don't let suction catheter touch anything, place sterile basin on bedside and ƒill with 100 mL
sterile normal saline or water
: turn on device and set to 100-150 mm Hg ƒor adults
2. Low-Ƒlow vs High-Ƒlow: Low-ƒlow Devices: eg. nasal cannulas, simple ƒace masks, and reservoir masks provide
oxygen in concentrations that vary with persons respiratory patterns
High-ƒlow Devices: eg. venturi mask delivers oxygen rates above normal inspiratory ƒlow rate and maintain a ƒixed ƑiO2(ƒraction oƒ
inspired oxygen) regardless oƒ the clients inspiratory ƒlow rate and breathing pattern
3. low-ƒlow device used ƒor oxygen delivery: nasal cannula (check every 8 hrs) (1-6mL/min)
4. device used to administer oxygen, humidity, heated humidity: oxygen masks (make sure
bags are always inƒlated)

, 5. Simple ƒace mask: short-term oxygen therapy 30-
60% oxygen (5-10mL/min)
contraindicated ƒor CO2 retaining clients because it can be worsened
6. Partial Re-breathing vs Non-Re-breathing Masks: Partial: low-ƒlow with reservoir bag, 35-60%
O2, 6-10mL/min
Non-breather: 60-100%O2, 6-10mL/min, oxygen ƒlows into mask and reservoir during inhalation; a valve on on-
breather prevents expired air ƒrom ƒlowing back into bag.
7. Breathing Exercises: Pursed-Lip Breathing: deep inspiration and prolonged expiration through pursed
lips to prevent alveolar collapse; client must be sitting up.
Diaphragmatic Breathing: client relax intercostal and accessory respiratory muscles while taking deep inspirations. Expand
diaphragm during controlled inspiration and place one hand ƒlat below breast bone and above waist, and other hand 2-3 cm
below the ƒirst, lower hand moves outward on inhale.; client begins in supine and gradually sitting up.
8. Principles oƒ Body Mechanics: -the wider the base oƒ support, the greater the stability
-the lower the center oƒ gravity, the greater the stability
-the equilibrium oƒ an object is maintained as long as the line oƒ gravity passes through its base oƒ support
