Lack of adequate ventilation and impairment of our respiratory system can quickly become life-threatening. There are many clinical conditions that may necessitate the use of chest tubes. When there is an accumulation of positive pressure in the chest cavity (where it should normally be negative pressure between pleurae), a patient will require chest drainage. Chest tubes may be inserted to drain body fluids or to facilitate the re-expansion of a lung. It is important for the clinician to determine the most appropriate tube size to use prior to intubation. The position of the chest tube is related to the function that the chest tube performs. When managing the care of patients who have chest tubes it is important to fully understand what to do in case problems arise. It is also important to be able to assess when the chest tube is ready to be discontinued. Nurses and other healthcare professionals who are responsible for the safe delivery of care should be knowledgeable about respiratory pathophysiology, signs of respiratory compromise, and the care and management of interventions that may be utilized to ensure adequate respiration.

Tubes and Attachments A chest tube, also known as a thoracic catheter, is a sterile tube with a number of drainage holes that is inserted into the pleural space. The pleural space is the space between the parietal and visceral pleura, and is also known as the pleural cavity. A patient may require a chest drainage system any time the negative pressure in the pleural cavity is disrupted, resulting in respiratory distress. Negative pressure is disrupted when air, or fluid and air, enters the pleural space and separates the visceral pleura from the parietal pleura, preventing the lung from collapsing and compressing at the end of exhalation. A small amount of fluid or air may be absorbed by the body without a chest tube. A large amount of fluid or air cannot be absorbed by the body and will require a drainage system (Bauman & Handley, 2011; Perry et al., 2014). The chest tube is connected to a closed chest drainage system, which allows for air or fluid to be drained, and prevents air or fluid from entering the pleural space. The system is airtight to prevent the inflow of atmospheric pressure. Because the pleural cavity normally has negative pressure, which allows for lung expansion, any tube connected to it must be sealed so that air or liquid cannot enter the space where the tube is inserted (Bauman & Handley, 2011; Rajan, 2013). The location of the chest tube depends on what is being drained from the pleural cavity. If air is in the pleural space, the chest tube will be inserted above the second intercostal space at the mid-clavical line. If there is fluid in the pleural space, the chest tube is inserted at the fourth to fifth intercostal space, at the mid-axillary line. A chest tube may also be inserted to drain the pericardial sac after open heart surgery, and may be placed directly under the sternum (Perry et al., 2014). The following are some of the conditions that may require a chest tube drainage system (Bauman & Handley, 2011; Perry et al., 2014):
A chest tube drainage system must always be placed below the drainage site and secured in an upright position (attached to the floor or an IV pole, as in Figure 10.4) to prevent it from being knocked over. A chest tube drainage system is a sterile, disposable system that consists of a compartment system that has a one-way valve, with one or multiple chambers, to remove air or fluid and prevent return of the air or fluid back into the patient (see Figures 10.5 and 10.6). The traditional chest drainage system typically has three chambers (Bauman & Handley, 2011; Rajan, 2013). Always review what type of system is used in your agency, and follow the agency’s and the manufacturer’s directions for setup, monitoring, and use. In general, a traditional chest tube drainage system will have these three chambers:
In addition to the three chambers, the drainage system has many safety features to ensure that high negative pressures can be monitored and relieved quickly. To review these safety features and additional information regarding the chambers of a closed chest tube drainage system, visit the Teleflex Medical Incorporated website. When a patient has a closed chest tube drainage system, it is the health care provider’s responsibility to assess the patient and the equipment frequently to ensure the equipment is patent and working effectively. The health care provider should:

Heimlich ValveA Heimlich valve (see Figures 10.7 and 10.8) is a small, specially designed flutter valve that is portable and mobile, allowing the patient to ambulate with ease. It attaches to the chest tube at one end and a drainage bag at the other. The drainage bag allows air and fluid to escape but prevents their re-entering the pleural space. The valve can be worn under clothing. The valve functions in any position, never needs to be clamped, and can be hooked up to suction if required (Gogakos et al., 2015).
What is the significance of subcutaneous emphysema in a patient after a chest tube placement?Subcutaneous emphysema was also associated with prolonged drainage, poor tube placement, tube blockage, side-port migration, and a greater number of chest tubes. Importantly, those with SE had a longer length of stay and increased mortality.
Which action will the nurse take to check for subcutaneous emphysema and a client with a chest tube?How should the nurse monitor for the complication of subcutaneous emphysema after the insertion of chest tubes? Palpate around the tube insertion sites for crepitus. Auscultate the breath sounds for crackles and rhonchi. Observe the client for the presence of a barrel-shaped chest.
How do you manage subcutaneous emphysema?Several methods have been described in the literature for the treatment of extensive subcutaneous emphysema, including: emergency tracheostomy, multisite subcutaneous drainage, infraclavicular “blow holes” incisions and subcutaneous drains or simply increasing suction on an in situ chest drain.
What are the complications of subcutaneous emphysema?Severe cases of subcutaneous emphysema can lead to respiratory failure, pacemaker failure, problems with the airways or heart, or tension pneumothorax (a collapsed lung).
