RESP 130 Week 8 - Airway Clearance Therapy

These flashcards cover key concepts and facts related to Airway Clearance Therapy discussed in Week 8.

What are the 5 general approaches to Airway Clearance Therapy (ACT)?

1. Chest physical therapy (CPT) 2. Cough (directed, huff) 3. PAP adjuncts (handheld devices) 4. High frequency compression (IPPB) 5. Mobilization/physical activity

What is the most effective type of Airway Clearance Therapy?

Mobilization/physical activity

What are the three requirements for normal airway clearance?

1. Patent airway 2. Functional mucociliary escalator 3. Effective cough

What can full obstruction from retained secretions lead to?

Atelectasis

What can partial obstruction from retained secretions lead to?

Increased work of breathing, air trapping, V/Q imbalances

What are 6 findings that indicate a need for ACT?

1. Loose, ineffective cough 2. Labored breathing pattern 3. Coarse inspiratory and expiratory crackles 4. Tachypnea/tachycardia 5. Fever 6. Chest radiography demonstrating atelectasis and infiltrates

What are the 3 different types of Chest Physical Therapy (CPT)?

1. Position/gravity 2. Cupping 3. Vibration

What is the Forced Expiratory Technique (Huff Cough)?

A modification of directed cough that consists of one or two forced expirations of middle to low lung volume without closing the glottis

What is the goal of a huff cough?

To clear secretion with less change in pleural pressure and less bronchial collapse

What is a Mechanical Insufflation-Exsufflation (MIE) device?

A cough assist device that applies positive pressure then abruptly reverses airway pressure to assist patient with cough

What are the indication for CPT?

CF, bronchiectasis, lobar atelectasis from mucus plugging

What are the indications for PEP therapy?

CF, COPD, atelectasis prevention

What are the indications for High Frequency Chest Wall Oscillation

CF, Neuromuscular disease patients

What are the indications for Intrapulmonary Percussive Ventilation (IPV)

CF, COPD, post-op patients

What are the indications for directed cough and Huff cough?

Nearly all patients with weak or ineffective cough

What are the indications for mechanical insufflation-exuffraltion?

Neuromuscular disorders, patients unable to generate sufficient expiratory force
