Deep Breathing & Coughing
• Airway clearance– Nrs Dx
• Ineffective airway clearance
– fluids
![Page 3: Specific Methods of Respiratory Management](https://reader035.vdocuments.net/reader035/viewer/2022062806/56814e8f550346895dbc3336/html5/thumbnails/3.jpg)
Breathing Exercises
• Goal– work of breathing – efficiency
• Diaphragmatic breathing
• Pursed-lip breathing
![Page 4: Specific Methods of Respiratory Management](https://reader035.vdocuments.net/reader035/viewer/2022062806/56814e8f550346895dbc3336/html5/thumbnails/4.jpg)
Breathing Exercises
• Diaphragmatic breathing– Gen info
• Diaphragm – muscle• Practice
– Procedure• Place 1 hand on
abdomen and other on chest
• Push out abd during I• Chest move very little
![Page 5: Specific Methods of Respiratory Management](https://reader035.vdocuments.net/reader035/viewer/2022062806/56814e8f550346895dbc3336/html5/thumbnails/5.jpg)
Breathing Exercises
• Pursed-lip Breathing– Gen info
• Used when SOB• Keep airway open during
E CO2 excretion• With diaphragmatic
breathing• Counting anxiety
![Page 6: Specific Methods of Respiratory Management](https://reader035.vdocuments.net/reader035/viewer/2022062806/56814e8f550346895dbc3336/html5/thumbnails/6.jpg)
Breathing Exercises
• Pursed-lip Breathing– Procedure
• I – slowly through nose– Count 2
• E– Through pursed lips– Count 4
![Page 7: Specific Methods of Respiratory Management](https://reader035.vdocuments.net/reader035/viewer/2022062806/56814e8f550346895dbc3336/html5/thumbnails/7.jpg)
Positioning
• Conserve energy• Max lung expansion• Pt specific– Fowlers– Chair – leaning forward
• Good lung down
![Page 8: Specific Methods of Respiratory Management](https://reader035.vdocuments.net/reader035/viewer/2022062806/56814e8f550346895dbc3336/html5/thumbnails/8.jpg)
Oxygen therapy
• Goal– Provide adequate
transport of O2– work– stress to myocardium
• Need for O2 based on– ABG’s– Clinical assessment
![Page 9: Specific Methods of Respiratory Management](https://reader035.vdocuments.net/reader035/viewer/2022062806/56814e8f550346895dbc3336/html5/thumbnails/9.jpg)
Oxygen therapy
• Cautions on O2 tx– Med!
• Except in emergency need MD Rx
• Give O2 only to bring the pt back to baseline– ***COPD– WHY?
![Page 10: Specific Methods of Respiratory Management](https://reader035.vdocuments.net/reader035/viewer/2022062806/56814e8f550346895dbc3336/html5/thumbnails/10.jpg)
Oxygen therapy
• COPD & O2– Normal - CO2 indicator to breath– COPD – O2 indicator to breath• d/t CO2 levels “burned” medulla sensor for CO2
– Medulla uses O2 to initiate breath
![Page 11: Specific Methods of Respiratory Management](https://reader035.vdocuments.net/reader035/viewer/2022062806/56814e8f550346895dbc3336/html5/thumbnails/11.jpg)
COPD & O2
• COPD + O2 • Resp • PaCO2 • Carbon dioxide narcosis & acidosis • Deathmosis
![Page 12: Specific Methods of Respiratory Management](https://reader035.vdocuments.net/reader035/viewer/2022062806/56814e8f550346895dbc3336/html5/thumbnails/12.jpg)

• Reasons for Trach– Laryngeal CA– Airway obstruction– Trauma– Tumor– Difficulty clearing airway– Prolonged mechanical
Ventilation
![Page 68: Specific Methods of Respiratory Management](https://reader035.vdocuments.net/reader035/viewer/2022062806/56814e8f550346895dbc3336/html5/thumbnails/68.jpg)
Tracheostomy
• Pt breaths through this opening, bypassing the upper airways
• Semi-fowler position post-op
• Cuff management– Usually 20-25mmHg
![Page 69: Specific Methods of Respiratory Management](https://reader035.vdocuments.net/reader035/viewer/2022062806/56814e8f550346895dbc3336/html5/thumbnails/69.jpg)
Tracheostomy
• If trach pulled out– Tracheal dilator to
keep stoma open until MD arrives and reinsert tube

Suctioning
General Info:• Frightening &
uncomfortable• Leads to Hypoxia• Leads to Vagal stim – Bradycardia – Cardiac arrest
![Page 71: Specific Methods of Respiratory Management](https://reader035.vdocuments.net/reader035/viewer/2022062806/56814e8f550346895dbc3336/html5/thumbnails/71.jpg)
Suctioning
• Not do PRN• Enc cough• Hold own breath
![Page 72: Specific Methods of Respiratory Management](https://reader035.vdocuments.net/reader035/viewer/2022062806/56814e8f550346895dbc3336/html5/thumbnails/72.jpg)
Suctioning
Oropharyngeal (clean) or nasopharyngeal (sterile) suctioning procedure• Gather equipment• Explain• Connect cath to suction tubing, keep cath. inside sterile sleeve• Turn on suction to level specified by facility (80-120 mmHg)
![Page 73: Specific Methods of Respiratory Management](https://reader035.vdocuments.net/reader035/viewer/2022062806/56814e8f550346895dbc3336/html5/thumbnails/73.jpg)
Suctioning
• Pour saline into sterile container• Put on sterile gloves• Suction small amt of saline into catheter to rinse and test
suction• Have pt take several breaths
![Page 74: Specific Methods of Respiratory Management](https://reader035.vdocuments.net/reader035/viewer/2022062806/56814e8f550346895dbc3336/html5/thumbnails/74.jpg)
Suctioning
• With thumb control uncovered, insert cath. through mouth/nose into pharynx until resistance is met or pt coughs
• Slowly withdraw cath, suction intermittently while rotating • < 15 sec
![Page 75: Specific Methods of Respiratory Management](https://reader035.vdocuments.net/reader035/viewer/2022062806/56814e8f550346895dbc3336/html5/thumbnails/75.jpg)
Suctioning
• Allow pt to rest• Repeat 2 more time if needed• If trach – DO NOT instill sterile saline into trach • If trach – hyperventilate before suctioning

Intubation
• Endotracheal tube (ET) – Mouth - trachea
• Most also mech ventilated• Damages vocal cords &
surrounding tissue– Only short term
• Long term – Tracheostomy
![Page 77: Specific Methods of Respiratory Management](https://reader035.vdocuments.net/reader035/viewer/2022062806/56814e8f550346895dbc3336/html5/thumbnails/77.jpg)
Mechanical Ventilators
General Info• Provide ventilation to
pt unable to breath effectively on own
• Use + pressure to push O2 air in via ET or Trach tube
![Page 78: Specific Methods of Respiratory Management](https://reader035.vdocuments.net/reader035/viewer/2022062806/56814e8f550346895dbc3336/html5/thumbnails/78.jpg)
Mechanical Ventilators
Indication for use• Cont. in PaO2• Cont. PaCo2• Persistent Acidosis
![Page 79: Specific Methods of Respiratory Management](https://reader035.vdocuments.net/reader035/viewer/2022062806/56814e8f550346895dbc3336/html5/thumbnails/79.jpg)
Mechanical Ventilators
Nrs Management• Advance directives• Assess/monitor pt• Setting per order• Respond to alarms• Tubing free of water• Airway clear• Manual resuscitation bag
at bedside
