Question | Answer |
---|---|
What is necessary for normal airway clearance? | Patent airway, functional mucociliary membrane, and an effective cough |
What are the four normal phases of a cough? | Irritation, Inspiration, Compression, Expulsion |
What happens during the irritation phase of a cough? | Abnormal stimuli provoke sensory fibers in the airway |
What happens during the inspiration phase of a cough? | Once stimulated, the brain generates a signal to the respiratory muscles to initiate deep inspiration |
What happens during the compression phase of a cough? | The glottis closes and the vocal cords contract to shut the larynx; expiratory muscles contract resulting in a rapid increase in pleural and alveolar pressure, often greater than 100 mmHg |
What happens during the expulsion phase of a cough? | Glottis opens producing a large pressure gradient between the alveoli and the airway opening; with continued contraction of expiratory muscles, pressure gradient causes violent, expulsive flow of air from the lungs |
What types of stimuli can provoke a cough? | Inflammation (infection), Mechanical (foreign body), Chemical (irritant gases/smoke), Thermal (cold air) |
What are the causes of impaired mucociliary clearance in intubated patients? | Endotracheal tube/trach tube, tracheobronchial suction, inadequate humidification, high FiO2 values, drugs, general anesthetics, opiates, narcotics, underlying pulmonary disease |
What is the definition of chest physiotherapy? | Refers to a diverse group of techniques designed to improve respiratory efficiency by: mobilizing secretions, preventing or reversing atelectasis, and enhancing the efficiency and condition of respiratory muscles |
What are the goals of bronchial hygiene/CPT? | To move bronchial secretions to the central airways via: gravity (postural drainage), external manipulation of the chest (percussion), and to eliminate secretions by cough (cough assistance) or aspiration with a catheter (suction) |
What factors should be considered when assessing the need for airway clearance therapy | Medical record – Hx of pulmonary problems, admission report (surgery/age/history), presence of artificial airway, CXR, PFT’s, ABG’s, patient assessment (vitals/posture/BS/breathing pattern/sputum production/general fitness) |
What are the indications for retained secretions? | Lack of sputum, labored breathing, fever, increased crackles or rhonchi, wheezing or diminished breath sounds |
What is the primary objective of turning? | Promoted lung expansion, improve oxygenation, prevent retention of secretions |
What are the ABSOLUTE contraindications for postural drainage? | Head/neck injury until stabilized, active hemorrhage with hemodynamic instability |
What "plumbing" problems are associated with turning? | Ventilatory disconnection, accidental extubation, accidental aspiration of ventilator circuit condensate, disconnection of vascular lines or urinary catheters |
What can be caused by mucus plugging? | Atelectasis, retained secretions, consolidation |
When should manual vibrations be applied during the breath? | During expiration |
What is Diaphragmatic breathing? | Helps to increase the contractile force of the abdominal muscles |
What is FET - huff coughing? | 1-2 forced expirations of middle to low lung volumes that rapidly expels air through an open glottis |
What is a manual cough? What type of patient would it be performed on? | Used on patients with spinal cord injuries or in disease states where abdominal muscles are weak; have patient take 3 deep breaths, on the third exhalations apply pressure inward and upward below diaphragm as the patient coughs |
What is ACB? | Cycles of breathing control, thoracic expansion, and FET |
What is the ACB sequence? | 1. Breathing control, 2. 3-4 Thoracic expansion, 3. Breathing control, 4. 3-4 Thoracic expansion, 5. Breathing control, 6. 1-2 FETs, 7. Breathing control |
What is Autogenic drainage? | Patient is in the sitting position, uses varying lung volumes and expiratory flows to promote drainage |
What is Phase 1 of Autogenic drainage? | Unsticking: full inspiratory capacity maneuver through the nose, with a 2-3 second breath hold, follows by breathing at low lung volumes until secretions are felt or heard – 10-20 breaths |
What is Phase 2 of Autogenic drainage? | Collection: breath at low to middle lung volumes until secretions are felt or heard; 10-20 breaths; instruct patient to breathe through the secretions and push the secretions up the airways |
What is Phase 3 of Autogenic drainage? | Evacuating: take a series of larger breathes near vital capacity and take several huff coughs |
What diseases are associated with chronic production of large volumes of sputum that would benefit from CPT? | Chronic bronchitis, cystic fibrosis |
What volume of mucus is required for airway clearance to be used? | 25-30 ml/day |
What are the hazards/complications of PDT? How would you handle them? | Hypoxemia, Increased ICP, Acute hypotension during the procedure, pulmonary hemorrhage, pain/injury to muscles, ribs, or spine, vomiting/aspiration, bronchospasm, dysrhythmias; if complication arise, STOP tx, return to resting position, notify DR |
What are the postural drainage positions? | REVIEW IMAGE FROM LECTURE; gravity is used to move secretions to the center of body and up and out |
How long should each postural drainage position be maintained? | 3-15 minutes |
What would indicated a successful PDT outcome? | Improved sputum production and lung sounds, patient subjective response to therapy, change in vitals, CXR, ABGs or sats, change in ventilator variables |
On what areas should percussion NOT be performed? | Tender sites or sites of trauma, bony prominences |
What are the contraindications for PAP therapy? | PTs unable to tolerate increased WOB, ICP > 20 mmHg, hemodynamic instability, acute sinusitis, active hemoptysis, untreated pneumothorax, known/suspected tympanic membrane rupture, recent trauma to head/face, epistaxis, esophageal surgery, nausea |
What does PEP therapy involve? | Involves active expiration against variable flow resistance |
What pressure should be reached during PEP therapy? | 10-20 cmH2O |
What is the definition of oscillation? | Rapid, vibratory movement of small volumes of air back and forth in the respiratory tract |
What are the parts of the HFCWC (vest)? | Variable air-pulse generator, inflatable vest |
What is IPV? | Pneumatic device that delivers a series of pressurize mini bursts at rates of 100-225 cycles per min (1.6 to 3.75 Hz) via mouthpiece |
What are the brand names of airway oscillating devices? | Flutter Valve, Quake, Acapella |
What are the segments of the Right Upper Lobe (RUL)? | Apical, Posterior, Anterior |
What are the segments of the Right Middle Lobe (RML)? | Later, Medial |
What are the segments of the Right Lower Lobe (RLL)? | Superior, Medial basal, Anterior basal, Posterior basal, Lateral basal |
What are the segments of the Left Upper Lobe (LUL)? | Apical-posterior, Anterior, Superior lingula, Inferior lingula |
What are the segments of the Left Lower Lobe (LLL)? | Superior, Anterior-Medial basal, Later basal, Posterior basal |
