- Complications when suctioning
-
hypoxemia
trauma to airway
nosocomial infection
cardiac dysrhythmia r/t hypoxemia - hyperoxygenation
- done manually with resuscitation bag or thru ventlator and performed by increasing the oxygen flow ( usually 100%) before suctioning and between attempts
- What size catheter is needed to suction the endotracheal or tracheostomy?
- the suction catheter should be 1/2 the diameter of the inside diameter of the tracheostomy or ET tube to prevent hypoxia.

-
there is copious amounts of secretions
but could cause secretions to go deeper which increases the risk of infection. use 100% oxygen for several breaths. - The overall goals for a client with oxygenation problems are to ?
-
maintain a patent airway
improve comfort and ease of breathing
maintain or improve pulmonary ventilation and oxygenation.

- Advantages of a closed airway tracheal suction system AKA in-line suctioning??
- client does not need to be disconnected from the ventilator
- Respiration
- term used to describe inhaling and exhaling air.
- Breathing is controlled by the
- medulla oblongata in the Brain Stem which is sensitive to increased concentrations of CO2 & hydrogen. Also controlled by chemoreceptors sensitive to decreased O2 & pH changes.
- Carina
- separates the right and left bronchi
- Ventilation:
-
External - exchange of gases (inspiration and expiration)
Internal - O2 exchanged at the cell level - orthopnea
- -Difficulty breathing in a reclining position
- Arterial Blood Gases (ABG)-
- Definitive information on resp status and metabolic balance. Determines pH (acid base balance) O2, CO2,02 sat
- Sputum Analysis
- Best time to collect sputum is first thing am. Have pt drink extra fluids. Rinse mouth prior - no mouthwash
- Acid FastTest
- -determines the presence of tubercle bacillus (TB) bacteria
- Bronchoscopy-
- Inspection of larynx, trachea and bronchi with an endoscope, looking for any abnormalities, obtaining tissue for biopsy and secretions collection. NPO until gag reflex returns, semi-fowler and on either side to facilitate removal of secretions, assess for bronchospasms or laryngospasm (wheezes/SOB). If bx is done monitor sputum for signs of hemorrhage. (Blood streaked sputum can be expected for a few days after biopsy).
- Pulse Oximeter
- non-invasive monitoring of arterial 02 saturation using infrared finger clip.
- History
-
? history of colds, ? pneumonia, ? COPD, ? sinus problems

- Oxygen Safety Reminders
-
* Oxygen is a medication therefore a physicianÂ’s order is needed to start or change it
* Oxygen is flammable
* Place a “NO SMOKING” SIGN wherever oxygen is in use
* It is a nursing responsibility to enforce safety rules against no smoking, matches or
anything that may cause a spark while oxygen is in the room
* Oxygen should always be turned on and running before it is attached to the patient
* Oxygen masks should be taken off periodically and wiped of perspiration and dirt
* Use extreme caution with large bore nebulizer tubing, it collects condensation
* Always use sterile distilled water in oxygen therapy -

cupping and clapping
postural drainage -
cupping and clapping - loosens secretion in chest
postural drainage - pt in different positions to facilitate drainage -
