Unit 5 Flashcards
Common signs of inadequate oxygenation
- decreased energy
- restlessness
- rapid, shallow breathing
- rapid heart rate
- sitting up to breath
- nasal flaring
- use of accessory muscles
- hypertension
- sleepiness, confusion, stupor, coma
Promoting oxygenation
- positioning
- breathing techniques
- oxygen therapy
Fowlers position
upright seated position
tripod position
seated position with the arms supported on pillows or arm rest
orthopneic position
pt leans forward over bedside table or chair back
chest physiotherapy
techniques including the postural drainage, percussion, and vibration
inspiration
breathing in
expiration
breathing out
ventilation
movement of air in and out of lungs
respiration
exchange of oxygen and carbon dioxide
external respiration
takes place at the most distal point in the airway between the alveolar and capillary membranes
internal respiration
occurs at the cellular level by means of hemoglobin and body cells
hypoxemia
insufficient oxygen within arterial blood
hypoxia
inadequate oxygen at the cellular level
normal pH **
7.35-7.45
normal Pao2
80-100 mmHg
normal PaCO2***
35-45mmHg
normal Sao2
95%-100%
normal HCO3**
22-26 mEq
ABG
lab test using arterial blood to evaluate or assess oxygenation
incentive spirometry
- technique for deep breathing using a calibrated device
- encourages pts to reach a certain volume of inspired air
hypercarbia
excessive levels of carbon dioxide in the blood
oxygen therapy
administering more oxygen than is present in the atmosphere to relieve or prevent hypoxemia
liquid oxygen unit
device that converts cooled liquid oxygen to a gas by passing it through heated coils
