Define Airway Clearance Techniques
Are intended to manage or prevent the consequences of impaired mucociliary transport or the inability to protect the airway (e.g., impaired cough).
The techniques may include breathing strategies, manual and mechanical techniques, and postural drainage.
Define Active Cycle of Breathing.
ACB technique was developed under the name “forced expiratory technique” to assist secretion clearance in patients with asthma.
The name of the technique was changed to “active cycle of breathing” to emphasize that ACB always couples breathing exercise with the huff cough.
It includes three phases: breathing control, thoracic expansion exercises, and forced expiratory technique.
Define Directed Cough.
Tries to compensate for the patient’s physical limitations to elicit a maximum forced exhalation.
Examples of directed coughing include forced expiratory technique and manually assisted cough.
Define Huffing,
A forced expiratory maneuver performed with the glottis open.
- similar to fogging a pair of glasses with your breath.
- although a huff does not produce the same airflow velocity as a cough, the potential for airway collapse is less.
Huffing may be reinforced by a quick adduction of the arms to self- compress the chest wall.
Define Postural Drainage.
Consists of positioning the patient so that gravity will help drain bronchial secretions from specific lung segments toward the central airways where they can be removed by cough or mechanical aspiration.
Define Percussion.
AKA cupping and clapping, is the rhythmic clapping or striking of the thorax with a cupped hand or mechanical percussor directly over the lung segment being drained.
This rhythmic sequence should last for several minutes and should not be painful
Define Vibration
The application of a fine, tremulous action on the chest wall over the lung segment being drained in the direction the ribs move during exhalation.
It may be performed manually or with a mechanical vibrator
Vibration should be performed during exhalation.
Postural Drainage Positioning: Apical Segments Right and Left Upper Lobes- Patient Position & technique.
Position: the pt is in a sitting position, leaning back 30-40 degrees
Technique: percussion and vibration are performed above the clavicles.
Postural Drainage Positioning: Posterior Segment Right Upper Lobe- Patient Position and Technique
Position: The pt is turned 1/4 from prone on the left side with the bed horizontal and the head and shoulder raised on a pillow
Technique: Percussion and vibration are performed around the medial border of the right scapula.
Postural Drainage Positioning: Posterior Segment Left Upper Lobe- Patient Position &Technique
Position: pt is turned 1/4 from prone on the right side with the bed horizontal and the head and shoulders raised on a pillow
Technique: percussion and vibration are performed around the medial border of the left scapula.
Postural Drainage Positioning: Lingula Left Upper Lobe- Patient Position and Technique
Position: the pt is turned 1/4 from supine on the right side with the foot of the bed elevated 12 inches
Technique: percussion and vibration are performed over the left chest between the axillary and the left nipple.
postural Drainage Positioning: Anterior Segments Right and Left Upper Lobes- patient position & technique
Position: the patient is in supine with the bed horizontal
Technique: Percussion and vibration are performed below the clavicles
Postural Drainage Positioning: Right Middle Lobe- Patient Position and Technique
Position: the pt is turned 1/4 from supine on the left side with the foot of the bed elevated 12 inches.
Technique: percussion and vibration are performed over the right chest between the axillary and the right nipple
Postural Drainage Positioning: Superior Segments Left and Right Lower Lobes- Patient Position and Technique
Position: the pt is prone with the bed horizontal.
Technique: percussion and vibration are performed below the inferior border of the left and right scapulae.
Postural Drainage Positioning: Anterior Basal Segments Left and Right Lower Lobes- Patient Position and Technique
Position: the patient is in supine with the foot of the bed elevated 18 inches.
Technique: percussion and vibration are performed over the lower ribs on the left and right side.
Postural Drainage Positioning: Posterior Basal Segments Left and Right Lower Lobed- Patient Position and Technique
Position: the patient is in prone with the foot of the bed and elevated 18 inched
Technique: percussion and vibration are performed over the lower ribs on the left and right side of the chest.
Postural Drainage positioning: Lateral Basal Segments Lower Lobes- Patient Position & Technique
Position: the patient is in sidelying with the foot of the bed elevated 18 inches
technique: percussion and vibration are performed over the lower ribs.
Apex of the Heart.
The lowest part of the heart formed by the inferolateral part of the left ventricle.
Base of the Heart.
The upper border of the heart involving the left atrium, part of the right atrium, and the proximal portion of the great vessels.
Endocardium
The endothelial tissue that lines the interior of the heart chambers and valves.
Epicardium.
The serous layer of the pericardium that contains the epicardial coronary arteries and veins, autonomic nerves, and lymphatics.
Myocardium.
The thick contractile middle layer of muscle cells that forms the bulk of the heart wall.
Pericardium.
A double- walled connective tissue sac that surrounds the outside of the heart and great vessels.
Aorta
The body’s largest artery and the central conduit of blood from the heart to the body that begins at the upper part of the left ventricle.
