Oxygenation

Thoracostomy

Creates an opening in the chest wall through which a chest tube (aka thoracic catheter) is placed, which allows air and fluid to flow out of the chest

How does a chest tube drain?

Gravity Suction

Spirometry

Measures the volume of air entering or leaving the lungs Post-op patient: incentive spirometer

Name some nervous system diseases that may affect breathing

Myasthenia gravis (chronic autoimmune condition that causes weakening of skeletal muscles) Guillain-Barre (autoimmune condition in which the PNS is attacked) Polio

Exhalation

a collapse of alveoli that prevents normal exchange of oxygen and carbon dioxide

When preparing the patient for trach tube cleansing, sensations the patient may experience that may cause the patient to experience anxiety would include a feeling of: a. choking b. coolness c. warmth d. tightness

a. choking

Pursed-lip breathing

deep inspiration and prolonged expiration through pursed lips to prevent alveolar collapse

Some nursing interventions of complications of nasal cannula O2 delivery?

humidify the O2 water based lubricant

Intrapleural pressure:

negative! less than atmospheric pressure, which is 760 mmHg at sea level

Nerve that stimulates the diaphragm to contract during inspiration

phrenic nerve

Diaphragmatic breathing

requires the client to relax intercostal and accessory muscles whiles taking deep inspirations

Huff cough

the client stimulates a natural cough reflex that is effective for clearing the airway

Physiological factors affecting oxygenation

- decreased oxygen-carrying capacity (CHF, anemia) - decreased inspired oxygen (chronic lung disease) - hypovolemia (anemia, dehydration) - increased metabolic rate (fever, SOB)

a. a client who has heart failure and is receiving 100% oxygen via a partial rebreather mask The nurse should frequently check the bag on a rebreather mask to ensure it inflates properly. If the bag is deflated, the client will rebreathe his own exhaled CO2 instead of receiving the prescribed oxygen dose. Also, oxygen is a gas that can cause toxicity and is high combustible. The higher concentrations of oxygen increase the risk of client injury.

After repositioning the client, which of the following actions should the nurse take next? a. encourage the client to take deep breaths b. observe the rate, depth, and character of the client's respirations c. prepare to administer oxygen d. give the client a back rub to help her relax

b. observe the rate, depth, and character of the client's respirations

A charge nurse is observing a newly licensed nurse perform tracheostomy care for a client. Which of the following actions by the newly licensed nurse requires intervention? a. obtaining hydrogen peroxide for tracheostomy care b. obtaining cotton balls for the tracheostomy care c. obtaining sterile gloves for the tracheostomy care d. obtaining a sterile brush for the tracheostomy care

b. obtaining cotton balls for the tracheostomy care Cotton ball particles can be aspirated into the tracheostomy opening, possibly causing a tracheal abscess.

Use of pulse oximetry with a patient who has a tracheostomy may provide indication that the patient needs: a. hydration b. suctioning c. humidification d. none of the above

b. suctioning The pulse ox will tell the RN if the patient's oxygen levels are falling below the acceptable range, as suctioning removes oxygen along with secretions. Hence the need for hyper oxygenating patients before and between each pass of suctioning

The purpose of tracheostomy site maintenance care include: a. preventing decannulation b. providing a stable, secure airway c. preventing obstruction d. all of the above

d. all of the above - decannulation is the removal of the tracheostomy tube; maintenance of the site ensures that the tube is secured via the ties - maintenance includes suctioning, which removes any secretions that buildup in the tube that could obstruct airflow - by ensuring that the site is free from obstructions and properly secured, the airway remains patent

Duration of suctioning is r/t development of hypoxemia; an early sign of hypoxemia is: a. vagal stimulation b. bradycardia c. diaphoresis d. tachycardia

e. all of the above

The nurse assesses a client with a closed chest tube drainage system. On inspection, the nurse notes that the system is cracked. What should the nurse do?

If the nurse notes that the chest tube drainage system is cracked, the chest tube should be disconnected from the system and submerged in a bottle of sterile water in order to maintain the water seal. The system will then need to be replaced. A clamp should be kept at the bedside in case the system needs to be changed. However, the nurse should never clamp a chest tube without a written prescription from the health care provider and per agency policy. The drainage system (chest tube & bottle of sterile water) should also be maintained below the level of the chest if this complication occurs.

The nurse needs to apply oxygen to a patient who has a precise oxygen level prescribed. Which of the following oxygen-delivery systems should the nurse select to administer the oxygen to the patient? a. nasal cannula b. Venturi mask c. simple face mask without inflated reservoir bag d. plastic face mask with inflated reservoir bag

a. nasal cannula

Which would be priority assessments for the nurse to perform? (select all that apply) a. SpO2 levels b. amount of sputum production c. change in respiratory rate and pattern d. pain in lower calf area

a. SpO2 levels b. Amount of sputum production c. Change in respiratory rate & pattern

Chest tube drainage system

The chest tube drainage system returns negative pressure to the intracellular space - Used to remove abnormal accumulations of air and fluid in the pleural space Water seal chamber: - water oscillates (moves up as they inhale & down when they exhale) - excessive bubbling indicates an air leak Suction control chamber: - gentle bubbling indicates there is suction and does not indicate that air is escaping from the pleural space An occlusive sterile dressing is maintained at the insertion site Keep the drainage system below the level of the chest and the tubes free of kinks, dependent loops, and other obstructions Encourage coughing and deep breathing Change position frequently to promote drainage and ventilation If the drainage system cracks or breaks, insert the chest tube into a bottle of sterile water, remove the cracked or broken system, & replace with a new system

A safety measure when performing tracheostomy care without an assistant is to: a. pre-cut ties so the patient is off ventilation a shorter time b. cut off old ties after new ties are in place and securely tied c. not change ties until you have assistance d. change ties only when they are soiled

b. cut off old ties after new ties are in place and securely tied - NEVER cut ties yourself. Can fray! - You can change ties without assistance, as long as you place the new ones on before removing the old ones

Valsalva maneuver

Chest tubes the client may be asked to take a deep breath, exhale, & bear down as the chest tube is removed

Closed pneumothorax

Chest wall is intact Rupture of the lung and visceral pleura (or airway) allows air into the pleural space

Tension pneumothorax

Chest wall is intact (closed) Air enters the pleural space from the lung or airway, and it has no way to leave There is no vent to the atmosphere as there is in an open pneumothorax Most dangerous when patient is receiving positive pressure ventilation in which air is forced into the chest under pressure The positive pressure is transmitted to the mediastinum (heart and great vessels) Mediastinal shift occurs when the pressure gets so high that it pushes the heart and great vessels to the unaffected side of the chest * can quickly lead to cardiovascular collapse * the vena cava cannot accept venous return * with no venous return, there is no cardiac output

Dyspnea management

Clinical sign of hypoxia - subjective sensation of difficult or uncomfortable breathing Associated with exaggerated respiratory effort, use of accessory muscles of respiration, nasal flaring, and marked increases in the rate and depth of respirations Airway management (keep airways patent) Hydration (maintain thin secretions with a fluid intake of 1500 to 2500 mL/day) Mobilization of pulmonary secretions Humidification with more than 4L/minute of oxygen Nebulization Chest physiotherapy

3 steps in the process of oxygenation:

1) ventilation: process of moving gases into and out of the lungs 2) perfusion: relates to the ability of the cardiovascular system to pump oxygenated blood to the tissues and return deoxygenated blood to the lungs 3) diffusion: responsible for moving the respiratory gases from one area to another by concentration gradients

Incentive spirometer

A patient inhales slowly and with an even flow to elevate the balls and keep them floating as long as possible to ensure a maximally sustained inhalation Recommended 5-10 breath sessions every hour awake

Nasal cannula

A simple, comfortable device used for precise oxygen delivery Attach to humidified oxygen source with a flow rate up to 6L/min (24% to 40% oxygen) If >4L/min, must humidify because of drying effects

Four basic factors that influence circulation, perfusion, and transport of respiratory gases to the tissues

1) physiological 2) developmental 3) lifestyle 4) environmental

Nebulization

Adds moisture or medications to inspired air by mixing particles of varying sizes with the air Ex. bronchodilators and mucolytic agents

Hypoventilation

Alveolar ventilation inadequate to meet the body's oxygen demand or to eliminate sufficient carbon dioxide Caused by atelectasis and collapsed alveoli In patients with COPD, the administration of excessive oxygen results in hypoventilation S/S: mental status changes, dysrhythmias, and potential cardiac arrest

Tracheostomy

An opening made surgically directly into the trachea to establish an airway. A tracheostomy tube is inserted into the opening and the tube attaches to the mechanical ventilator or other type of oxygen delivery device. Can be temporary or permanent. Interventions: - Assess respirations & for bilateral breath sounds - Monitor arterial blood gasses and pulse ox - Encourage coughing & breathing exercises - Maintain a semi-Fowler's to high Fowler's position - Monitor for bleeding, difficult with breathing, absence of breath sounds, and crepitus (subcutaneous emphysema), which are indications of hemorrhage or pneumothorax - Suction fluids as needed; hyper oxygenate the client before suctioning - Assess the stoma and secretions for blood & purulent drainage - Obtain assistance in changing tracheostomy ties; after placing the new ties, cut and remove the old ties holding the tracheostomy in place

When do you change the chest tube dressing?

Around 72 hours Only as needed

Face mask with reservoir bag

Capable of delivering higher concentrations of oxygen - Partial rebreather: reservoir bag should be at least 1/3 to 1/2 full on inspiration ; delivers from 40% to 70% FIO2 with a flow rate of 6 to 10 L/min Frequently inspect the reservoir bag to make sure it is inflated! High-flow systems should be humidified

Chest physiotherapy (CPT)

Group of therapies for mobilizing pulmonary secretions Include postural drainage, chest percussion, and vibration Postural drainage: drainage, positioning, and turning. Sometimes accompanied by chest percussion and vibration. Chest percussion: rhythmically clapping on the chest wall over the area being drained to force secretions into larger airways for expectoration (hands should be cupped) - Contraindicated for patients with bleeding disorders, osteoporosis, or fractured ribs. Avoid over burns, open wounds, or skin infections of the thorax. Vibration: gentle, shaking pressure applied to the chest wall to shake secretions into larger airways

Suctioning

Includes oropharyngeal, nasopharyngeal, orotracheal, nasotracheal, & tracheal Apply negative pressures (not greater than 150 mmHg) during withdrawal of the catheter, never on insertion!!

Hemothorax

Occurs after thoracic surgery and many traumatic injuries The negative pressure between the pleurae is disrupted, and the lung will collapse to some degree, depending on the amount of blood Risk of mediastinal shift is insignificant, as the amount of blood needed to cause it would result in life-threatening intravascular loss

Pneumothorax

Occurs when there is an opening on the surface of the lungs or in the airways, in the chest wall, or in both The opening allows air to enter the pleural space between the pleurae, creating an actual space Two types: open and closed

Open pneumothorax

Opening in the chest wall (with or without lung puncture) "Sucking chest wound" Allows atmospheric air to enter the pleural space Air moves in and out of the chest through the opening of the chest wall. Looks bad and sounds worse, but the opening acts as a vent so pressure from trapped air cannot build up in the chest Penetrating trauma (stab, gunshot, impalement) or surgery

Tracheal suctioning

Performed through an artificial airway such as an endotracheal tube or a tracheostomy tube Size of catheter should be about half the internal diameter of the lumen Never apply suction pressure while inserting the catheter to avoid traumatizing the lung mucosa One inserted, maintain suction pressure between 120 and 150 mmHg as you withdraw Apply suction intermittently only while withdrawing the catheter Rotating the catheter enhances the removal of secretions that have adhered to the sides of the tube

Conditions requiring chest drainage

Pneumothorax (air between the pleurae) Hemothorax (blood in the pleural space) Pleural effusion (transudate or exudate in the pleural space)

Maintenance and promotion of lung expansion

Positioning - semi-Fowler's * reduces pulmonary stasis, maintains ventilation and oxygenation * uses gravity to assist in lung expansion and reduces pressure from the abdomen on the diaphragm Incentive spirometry: * encourages voluntary deep breathing * used to prevent or treat atelectasis Chest tubes * a catheter placed through the thorax to remove air and fluids from the pleural space or to prevent air from reentering or to reestablish intrapleural and intrapulmonic pressures

Conditions affecting chest wall movement

Pregnancy Obesity Musculoskeletal abnormalities Trauma Neuromuscular disease CNS alterations

Oral airway

Prevents the obstruction of the trachea by displacement of the tongue into the oropharynx

Endotracheal airway

Short-term use to ventilate, relieve upper airway obstruction, protect against aspiration, & clear secretions

Hyperventilation

The lungs remove carbon dioxide faster than it is produced by cellular metabolism Can be caused by severe anxiety, infection, drugs, or an acid-base imbalance S/S: rapid respirations, sighing breaths, numbness and tingling of hands/feet, light-headedness, and loss of consciousness

Humidification

The process of adding water to gas Necessary for patients receiving oxygen therapy at greater than 4L/min

Simple face mask

Used for short-term oxygen therapy Delivers 35% to 50% FIO2 Contraindicated for patients with CO2 retention because retention can be worsened Flow rates should be 5L or more to avoid rebreathing exhaled CO2 retained in the mask

Nasopharyngeal suctioning

Used when the client can cough effectively but is not able to clear secretions

Oropharyngeal suctioning

Used when the client can cough effectively but is not able to clear secretions

Nasotracheal suctioning

Used when the client is unable to manage secretions Sterile technique Preferred to orotracheal suctioning because the stimulation of the gag reflex is minimum The entire procedure from catheter passage to its removal is done in less than 15 seconds Allow patient to rest between passages unless in respiratory distress

Orotracheal suctioning

Used when the client is unable to manage secretions Sterile technique The entire procedure from catheter passage to its removal is done in less than 15 seconds Allow patient to rest between passages unless in respiratory distress

Health promotion for oxygenation

Vaccinations: Influenze, pneumococcal Healthy lifestyle: Eliminate risk factors, eat right, regular exercise Environmental pollutants: Second-hand smoke, work chemicals, & pollutants

Any condition that reduces the chest wall movement will result in decreased ____________

Ventilation If the diaphragm is unable to descend fully with breathing, the volume of inspired air decreased, delivering less oxygen to the alveoli and all tissues

When do you change the drainage system?

When it is full When it tips over If it is compromised

Boyle's Law

When temperature is constant, pressure is inversely proportional to volume When the volume of a container increases, the pressure decreases When the volume of a container decreases, the pressure increases

Inspiration

When the diaphragm contracts, it moves down, increasing the volume of the thoracic cavity (decreased pressure) Air moves from an area of higher pressure (the atmosphere) to an area of lower pressure (the lungs)

A nurse is performing suctioning for a client who has a tracheostomy. Which of the following actions should the nurse take? a. pull suction catheter back 1 cm (0.5 in) if the client starts coughing b. allow 30 seconds between suctioning passes c. hyperventilate the client with 50% oxygen for 30 seconds d. perform a maximum of 4 passes with the suction catheter

a. pull suction catheter back 1 cm (0.5 in) if the client starts coughing The nurse should pull the suction catheter back 1cm when the client starts to cough, or resistance is met. This will remove the catheter from the mucosal wall of the trachea prior to suctioning. - The nurse should allow 1 minute between suctioning passes to prevent hypoxia & to hyperventilate the client - The nurse should administer 100% oxygen for at least 2 minutes prior to suctioning to decrease hypoxia - The nurse should perform a max of 3 passes with the suctioning catheter

All of the following conditions are contraindications to the use of percussion and vibration except: a. pneumothorax b. hemoptysis c. cystic fibrosis d. chest pain

c. CF

The nurse is assessing the functioning of a chest tube drainage system in a client who has just returned from the recovery room following a thoracotomy with wedge resection. Which are the expected assessment findings? (select all that apply) a. excessive bubbling in the water seal chamber b. vigorous bubbling in the suction control chamber c. drainage system maintained below the client's chest d. 50 mL of drainage in the drainage collection chamber e. occlusive dressing in place over the chest tube insertion site f. fluctuation of water in the tube in the water seal chamber during inhalation and exhalation

c. drainage system maintained below the client's chest d. 50 mL of drainage in the drainage collection chamber e. occlusive dressing in place over the chest tube insertion site f. fluctuation of water in the tube in the water seal chamber during inhalation and exhalation The bubbling of water in the water seal chamber indicates air drainage from the client and is usually seen when intrathoracic pressure is higher than atmospheric pressure (negative pressure is desired). Bubbling in the water seal chamber may indicate an air leak, which is an unexpected finding. Gentle (not vigorous) bubbling should be noted in the suction control chamber. Positioning below the client's chest allows gravity to drain the pleural space. A total of 50 mL of drainage is not excessive in a client returning to the unit. More than 70-100 mL/h is considered excessive. Fluctuation of water in the tube during inhalation and exhalation is expected. If fluctuation is absent, it may indicate that the tube is obstructed or that the lung has reexpanded and that no more air is leaking into the pleural space.
