So instillation of saline and the immediate aspiration of saline does make some senseinstillation of saline and then deep bagging it into the lung and then putting in a suction catheter down into the tube makes no sense whatsoever. The option to breathe and thus humidify orally is virtually nonexistent for our smaller patients, particularly infants who are obligate nose breathers. That's why I'm not very supportive of the VDR [volumetric diffusive respiration] ventilation mode, because I'm worried that it is delivering large tidal volumes chronically, but I am supportive of using it intermittently, say every 4 hours, with a ventilator to help remove secretions, because then it's just another airway-clearance device: not a ventilation mode. Correspondence: Brian K Walsh MBA RRT-NPS FAARC, Department of Respiratory Care, Children's Medical Center Dallas, 1935 Medical District Drive, Dallas TX 75235. Risks associated with ineffective breathing pattern include: Risk for infection. Relaxing airway smooth muscle with bronchodilation may reduce the effectiveness of airway peristalsis for mucus propulsion. The question arises as to what is appropriate airway clearance in an acute disease process? Having just written about this for another Journal Conference,1 I have a couple of comments. Yet these are missing in infants in which these collaterals are not well developed.

Investigations have been conducted to determine the relative importance of percussion, vibration, and postural drainage. . A lot of people are scared to turn up the ventilator knobs during in-line suctioning or shortly after, but they're not scared to squeeze a bag harder, because those pressures are not documented. These techniques include postural drainage, percussion, chest-wall vibration, and promoting coughing. It is reasonable to consider that inflammation in the airways is associated with acidification. This can be effectively accomplished with breath-stacking, manually assisted cough, and mechanical insufflation-exsufflation. Some support the cough and respiratory effort or drive by utilizing noninvasive ventilation to limit fatigue, whereas others utilize PEP therapy to prevent distal airway collapse. It's actually how we ventilate during suctioning. Without expiratory gas moving against it, the mucus becomes trapped. Risk for Ineffective Airway Clearance related to suppression of respiratory system Impaired Skin Integrity related to constant activity, diarrhea Altered Nutrition: Less than Body Requirements related to vomiting and diarrhea, uncoordinated suck and swallow reflex, hypertonia secondary to withdrawal Endotracheal suctioning of mechanically ventilated patients with artificial airways: 2010, http://www.osha.gov/dts/osta/anestheticgases/index.html, Physiologic and Pathophysiologic Considerations, Unique Considerations in Infants and Children, Airway Clearance Therapies in the Acute Setting, Future of Airway Maintenance and Clearance. Nursing Interventions for Ineffective Airway Clearance 1. Many airway-clearance techniques are not benign, particularly if they are not used as intended. ARDS causes impairment in gas exchange, as a result, the lungs could not provide enough oxygen. The aerosolization of contaminated water in hospital humidifiers and/or room humidifiers is a potential source of nosocomial infection.42 Specifically, small room humidifiers have been associated with passing Legionella,43 are hard to clean, and require between-patient sterilization and the use of sterile or distilled water to prevent cross-contamination. Perhaps at the bedside the clinician should decide what method should be used, with the primary goal of secretion removal versus lung-volume retention, and occasionally do open suctioning. Increased nasal swelling and epistaxis are common traumatic results of deep suctioning. NANDA-I diagnosis: Ineffective Airway Clearance (00031) Definition: . During airway peristalsis the airway becomes narrowed at the point of the mucus. Small changes in airway diameter due to edema, secretions, foreign body, or inflammation can lead to drastic changes in resistance. The oldies but goodies. The respiratory therapist implements classic airway-clearance techniques to remove secretions from the lungs. In open suctioning, volume loss is independent of catheter size.56 This may be explained by the probable presence of turbulent flow between the ETT and suction catheter during closed suctioning.52 The concept that closed suctioning is better because it prevents volume loss may be incorrect. Ineffective thermoregulation related to newborn status and stress from birth weight variation. With an effective nursing care plan, many of these risks and complications can be avoided. I have to document the ones I set on the ventilator. The patient's cough will always be our strongest ally in airway maintenance. This decreases mucociliary activity, which further hinders airway clearance (Table 2).89,91,93, A key factor in secretion clearance is being able to get enough air distal to the mucus. The primary goal of airway maintenance and clearance therapy is to reduce or eliminate the consequences of obstructing secretions by removing toxic and/or infected material from the bronchioles. Nasal CPAP stabilizes the small airways and maintains FRC, which may restore balance to the mucociliary ladder.77 Nasal CPAP may open airways and allow gas to move beyond secretions and to expel them. These include: acid reflux seizures coma cancer in any part of the upper digestive system, such as the mouth, throat, and esophagus head and neck injuries stroke eating and drinking too fast dental issues mouth sores This reduction proceeded quickly to complete cessation. There are certain factors that may raise the risk that your newborn will have a breathing condition: Premature delivery: This is the most common. Risk for suffocation. The negative pressure from the suction catheter triggers the ventilator, and the incoming gas forces the secretions away from the suction catheter. The American Association for Respiratory Care clinical practice guidelines on postural drainage69 define difficulty clearing secretions as a sputum production greater than 2530 mL per day. Traditional airway maintenance and clearance therapy and principles of application are similar for neonates, children, and adults. I'm a little nervous about clamping, because I've heard of having a hard time getting the clamp off, especially with some of the older metal ones. Secretion clearance techniques: absence of proof or proof of absence? Proper heating and humidification of inspiratory gas keeps the mucociliary ladder moving at a natural pace. The incidence of bleeding after thyroid surgery is low (0.3-1%), but an unrecognized or rapidly expanding hematoma can cause airway compromise and asphyxiation. The ideal frequency of percussion is unknown; however, some reports recommend a frequency of 56 Hz, whereas others recommend slower, rhythmic clapping.3,4 Several devices can be used for percussion, including a soft face mask or a commercially designed palm cup or pneumatic or electro-mechanical percussor. While the studies reviewed were far from conclusive, the risk/benefit ratio leads most facilities to employ active humidification for smaller patients. I'm interested in seeing some controlled studies, rather than just approval, but it does potentially make sense to use that as opposed to something like saline. Specifically, exhaled-breath-condensate pH could be used as a safe, noninvasive screening or preventive tool for ventilator-associated pneumonia (VAP),21 or possibly impaired ciliary motility. In chronically obstructed patients there may be finger-like mucoid impaction of the airways and abnormal airway dilation (bronchiectasis). When we first found out that the lung is so acidic, we were wondering whether this acidification is actually beneficial. The most interesting finding was not the pH, but the fact that various bacteria from patients with VAP grew better at a slightly acidic pH. This collapse is avoided by opposing forces that make up the rigidity of the airway structure, specifically smooth muscle in the peripheral airways and cartilage in the central airways. Segments, lobes, and entire lungs may be collapsed, or atelectatic from mucus plugs. Using the Murray Lung Injury Score, he was able to correlate severity (r = 0.73, P < .001) and concluded that exhaled-breath-condensate pH is a representative marker of acute lung injury caused by or accompanied by pulmonary inflammation.18 More recently, Pugin and colleagues found that patients mechanically ventilated for various reasons (eg, ARDS, pneumonia, and after cardiac surgery) had a substantially lower exhaled-breath-condensate pH than healthy controls. -Ineffective airway clearance (AEB cough) -Risk for ineffective breathing . I've used bicarbonate a lot in kids I'm trying to get secretions out of, but I had never really delved into the physiologic reasons of why it might help, so thanks for explaining that. A common breath sound heard in children with bronchiolitis is wheezing, which is probably caused by increased resistance to air flow from secretions and/or inflamed airways; yet studies have not revealed that additional airway clearance such as CPT is beneficial. Lasocki et al showed that that's what happens,2 and I think it explains why more secretions are removed with open-circuit suctioning. The group chose to look at the actual amount of sputum produced. I want by priority nursing dx to be risk for ineffective airway clearance because the newborn developed a croupy cough. In patients receiving heliox therapy, the nitrogen balance is often completely replaced with helium. Sometimes it takes 510 cm H2O above on the ventilator to achieve that, but I try to stay below a peak pressure of 35 cm H2O during re-recruitment maneuvers. This loss of volume may shift fissures toward the area of atelectasis, or cause mediastinal shift toward the affected side. The human body has several mechanisms to keep the airway free from occlusions such as the presence of microorganisms in the airway, the presence of small hair in the nostrils, and the ability to cough to clear out obstructions. Risk for ineffective airway clearance r/t presence of mucus in mouth and nose at birth . Regarding the financial aspect, remember that, regardless of the device or method, airway clearance is billed under one Current Procedural Terminology billing code number. Exhaled-breath condensate is a technique that samples the airway-lining fluid that has advanced our understanding of airway chemistry. Studies have shown that airway clearance therapy is associated with decreased oxygen saturation, gastroesophageal reflux, fractured ribs, raised intracranial pressure, and even brain injury.81 Selection of a best technique is currently more of an art than a science, and depends greatly on the patient's underlying condition, level of functioning and understanding, and ability and willingness to perform the technique and integrate it into normal daily routines.82, Airway dysfunction begins during the first year of life, with the earliest pathologic change being thickened mucus and plugging of the submucosal gland ducts in the large airways.83 Goblet cells and submucosal glands are the predominant secretory structures of normal airways. When accompanied by percussion or vibration, each position is maintained for 15 minutes, depending on the severity of the patient's condition. Intrapulmonary percussive ventilation is intriguing; I think it does that by using fairly large volumes. Although that approach increases the number of clinicians available to assist with secretion clearance, the overall process tends to be inefficient. Physical activity and exercise programs have been shown to augment airway clearance. Other studies have reported that percussion without postural drainage or cough produced minimal change in mucus clearance. Ineffective Airway Clearance. There is scant evidence for CF in regards to airway-clearance techniques for infants, though the committee suggests starting airway-clearance techniques as early as a few months old so that the parents can begin making this part of their daily routine.86, Since there is scant evidence from infants and pediatric patients with CF, how do we choose the appropriate therapy for the acute phase of the disease process? Sulfomucins are prevalent at birth, and sialomucins become evident over the first 2 years of life.10 Submucosal glands that are responsible for producing most of the body's mucus are 5% larger in the pediatric airway11 than in the adult airway. Heliox is a less dense gas: 1/7th that of air. The clinician places the patient in various positions designed to drain specific segments of the lung. Unfortunately, more questions than answers remain. b. I would rather just use the ventilator, where I can monitor the volumes of those big breaths. As our profession matures, we hope that practices like this will not evolve without substantial research to ensure that we are not contributing to the high cost of healthcare or, even more importantly, are not causing harm. The second thing is about closed suctioning. In neonates receiving high-frequency oscillatory ventilation (HFOV), closed versus open suctioning produced essentially equal drops in saturation and heart rate, but recovery time from those drops was significantly longer in the open-suctioning group. Interventions to restore natural balance should be the first step in any airway maintenance program; however, much more research is needed. Proper humidification effects more than just sputum viscosity. Airway secretions are relatively dehydrated and viscous. What does chest physiotherapy do to sick infants and children? During closed suctioning in a time-cycled pressure-limited mode, the pressure variations within the ventilator circuit were minimal. Da Silva et al found, in a study of 45 children < 1 year old, that adventitious breath sounds and sputum production had the highest positive predictive value for insufficient airway clearance.70 But does the presence of adventitious breath sounds indicate that the patient is getting worse? In 1982, a randomized study of CPT in 44 postoperative pediatric cardiac patients found that CPT failed to prevent atelectasis, compared to no intervention.109 A recent Cochrane review of CPT (vibration or tapping on the chest) in babies following extubation concluded that there was no clear benefit to peri-extubation CPT, and no decrease in post-extubation lobar collapse, but there was an overall lower re-intubation rate in those who received CPT.110 Flenady et al advised caution when interpreting the possible benefits of CPT; because the number of infants studied was small, the results were not consistent across trials, data on safety was insufficient, and application to current practice may be limited by the age of the studies.110. Nursing diagnoses of newborns with sepsis in a Neonatal. A study of 200 neonates who weighed < 1,000 g found twice the recovery time with open suctioning versus closed suctioning.57 In a smaller pediatric study the results were the same, indicating benefits from closed suctioning. Pressure limits in adaptive pressure ventilation should be set carefully to avoid volutrauma after suctioning. Which of the following measures would the nurse take first to help ensure that breathing and blood oxygen saturation remain adequate? In the pre-heated high-flow nasal cannula group, 32% of infants with respiratory syncytial virus were managed on room air or blow-by oxygen. Caution should be used, given that the conclusions are based on very limited data (Fig. Small airway caliber in the lung positioned uppermost is also increased. In my experience, giving it quite frequently, I've had some intensivists who are advocates of using bicarbonate. Dick Martin, at Origin, took that over. To gain a better understanding, we looked at the CF literature. Gravity can then assist in moving secretions through larger airways conducting higher flows.34. A recent study in neonates compared routine use of a low-sodium solution versus routine use of normal saline. Until then we will continue to offer a wide range of airway-clearance techniques to match the diverse patient population. During CPT on small infants, the clinician should utilize a modified technique, even though it may not lead to the best postural drainage. In acute asthma there appears to be no benefit from CPT. This practice reduces the humidity deficit and potentially lowers airway resistance. Available disease-specific evidence of airway-clearance techniques and airway maintenance will be discussed whenever possible. Vibrations are an additional method of transmitting energy through the chest wall to loosen or move bronchial secretions. If clinicians used only therapies that have been proven to work, we would be back to the basics. The forceful expiration is preceded by glottic closure, allowing for pressure build. Suction as needed. a. Goal: Newborn will maintain airway aeb having a respiratory rate within normal range of 30 to 60 breaths per minute, showing no signs of respiratory distress (McKinney & Murray, 2010). During respiratory viral season the outdoor humidity drops further as the air temperature declines. In Airway Clearance for the Term Newborn, Adams et al. In November of 2006 the Pulmonary Therapies Committee began preliminary discussions on the establishment of guidelines for the clinician on the use of best adjunctive therapy for the CF patient. A new question in the pulmonary laboratory, Exhaled breath condensate: an evolving tool for noninvasive evaluation of lung disease, Cyclic stretch of human lung cells induces an acidification and promotes bacterial growth. Brian, regarding airway alkalization, you seemed to imply that at least Pseudomonas grows better in an acidic pH, but later you said that maybe acidification is a host defense. An in vivo adult study comparing the use of heated-wire circuits to non-heated-wire circuits in the delivery of humidified gas reported an increase in sputum volume with the usage of non-heated-wire circuits.48 Perhaps there was a reduction in retained secretions or just increased rainout in the large airways. This question is for testing whether or not you are a human visitor and to prevent automated spam submissions. There is a lack of evidence on the role of deep suctioning (nasal pharyngeal or nasal tracheal) in viral processes. Thick and viscid mucus is such a common feature that at one time the disease was referred to as mucoviscidosis.84, Mucociliary clearance is variable in CF, with some patients having severe impairment, whereas others have normal clearance. 3. of 2 Problem: Risk for Ineffective Airway clearance r/t the excessive fluid and mucus in the newborns respiratory passages. Neonates' very small airways are subject to closure, especially with application of increased pleural pressure. They corrected that by increasing the suctioning pressure to 300 mm Hg in adults. Skoog reported a winter relative indoor humidity level of 16.2%,41 creating an extremely dry atmosphere. However, the mean tracheal pressure changed as much as 115 cm H2O. 3. The clinical picture of airway collapse often prompts CPT or bronchodilator orders. Schechter et al suggested that efficacy studies of airway-clearance techniques in infants and children have been underpowered and otherwise methodically suboptimal.72 While it doesn't appear that there is a single indicator for airway clearance, breath sounds may be our best tool. Re to: Adjustment to . She also had weak muscle tone. This action results in swollen turbinates, which can lead to nasal congestion and increase airway resistance, thus escalating a patient's respiratory work load.44. The key would be demonstrating a shorter duration of ventilation, shorter ICU and/or hospital stay, and limiting equipment and medication expenses. Is there equipoise? This airway collapse can be further exaggerated when CPT is performed or bronchodilators administered. We use plastic ones now that you can break if you have to. Ineffective Airway Clearance May be related to Copious secretions Decreased energy and fatigue Presence of artificial airway: tracheostomy Thick secretions Possibly evidenced by Abnormal breath sounds (crackles, rhonchi) Dyspnea Ineffective cough Increased breathing effort: nasal flaring, intercostal retractions, use of accessory muscles But because it's so irritating, it does carry risks, and if you use bicarbonate, I would be cautious about it. The advantage of heliox is that it creates laminar flow, which lowers work of breathing associated with high airway resistance, potentially provides better aerosol distribution, which may improve therapeutic effect and outcome.92 The laminar flow may be a disadvantage when it comes to airway clearance, because turbulent flow is required to break up and move mucus out of the airways. After being a therapist for many years and seeing how some practices we adopted ended up hurting our patients, I think it's interesting that the jury's still out. CF is considered the cornerstone disease process for secretion clearance. Airway clearance continues to be used excessively and on patients in whom it is contraindicated. It is a life-threatening condition of capillary endothelial injury and diffuse alveolar damage. * Mark Rogers RRT, CareFusion, San Diego, California. Research will continue to focus on new and novel therapies such as airway alkalization, low-sodium solutions for suctioning, nebulized hypertonic solutions, and proactive airway humidification. It takes time, and you have to sit there. pH probe monitoring cannot detect whether reflux contents reach the airways. The possible advantages of normal saline for adults and low-sodium saline solution in neonates prompt careful consideration of routine pre-suctioning saline instillation in the pediatric population. Implications for asthma pathophysiology, Airways in cystic fibrosis are acidified: detection by exhaled breath condensate, pH in expired breath condensate of patients with inflammatory airway diseases, Exhaled breath condensate acidification in acute lung injury, How acidopneic is my patient? In our institution we are working on an initiative to center secretion clearance responsibility with the respiratory therapy program. Clinicians should not percuss over bony prominences, the spine, sternum, abdomen, last few ribs, sutured areas, drainage tubes, kidneys, liver, or below the rib cage. If necessary the patient may be supported by rolled towels, blankets, or pillows.

When I use an in-line suction catheter, if I see oxygen saturation go up when I'm suctioning, I think that I over-distended them, and those secretions would probably come out better with a lower mean airway pressure, and maybe the best thing to do is take them off, lower their lung volume, and bag and suction them, then reestablish or reevaluate FRC again. Risk of impaired gas exchange. So other studies should compare nothing or adequate humidification, and suctioning to whatever the new technique is. Plioplys et al104 found fewer pneumonias and respiratory-related hospitalizations in 7 quadriplegic cerebral palsy patients.
