Chest Tubes by Charlotte Cooper RN, MSN, CNS modified by Kelle Howard RN, MSN Breathing: Inspiration • Diaphragm contracts • Moves down • Increasing the volume of the thoracic cavity • When the volume increases, the pressure inside ________. • Pressure within the lungs is called intrapulmonary pressure Breathing: Exhalation • Phrenic nerve stimulus stops • Diaphragm relaxes • This ______ the volume of the thoracic cavity • Lung volume decreases, intrapulmonary pressure _____ Pleural Anatomy – Parietal pleura – lines the chest wall – Visceral pleura (pulmonary) – covers the lung Visceral pleura Parietal pleura Lung Pleural Anatomy Intercostal muscles Ribs Normal Pleural Fluid Quantity: Approx. 20 - 25mL per lung Pleural Physiology • Area between pleura ----“potential space” • Normally, negative pressure between pleura What do you do when pleural injury occurs Pleural Injury: Therapeutic Interventions • Diagnostic tests • Client position • Treatment depends on severity – Chest tube – Heimlich valve on chest tube Chest Tubes • Also called “thoracic catheters” • Different sizes – From infants to adults – Small for air, larger for fluid • Different configurations – Curved or straight • Types of plastic – PVC – Silicone • Coated/Non-Coated – Heparin – Decrease friction Chest Tube Placement • In what setting/environment is a chest tube placed? Chest Tube Placement Chest Tube Placement Procedure • • • • Sterile technique Small incision Tube is sutured Dressing applied Chest tubes in place Heimlich Valve Heimlich Valve http://www.scielo.br/img/revistas/jbpneu/v34n8/en_a04fig01.gif Treatment goal for pleural injuries 1. Remove fluid & air as promptly as possible 2. Prevent drained air & fluid from returning to the pleural space 3. Restore negative pressure in the pleural space to re-expand the lung How a chest drainage system works How a chest drainage system works • Expiratory positive pressure • One way valve • Gravity • Suction Goal: Tube open to atmosphere vents air Prevent Air and Fluid Backflow Tube from patient Goal: Prevent Air and Fluid Backflow • For drainage, a second bottle was added • The first bottle collects the drainage • The second bottle is the water seal • With an extra bottle for drainage, the water seal will then remain at 2cm From bottles to a box To suction From patient from patient Suction control bottle Water seal bottle Collection bottle Suction control chamber Water seal chamber Collection chamber From box to bedside Water suction (A) Dry suction (B) Lewis p. 570 Fig 28-8 Atrium Chest Tube System • Chamber A – Suction control chamber • Chamber B – Water seal chamber • Chamber C – Air leak monitor • Chamber D – Collection chamber Be sure you under stand how to set up the system, the function of each chamber and how to troubleshoot issues with each chamber. Restore negative pressure in the pleural space The depth of the water in the suction bottle determines the amount of negative pressure that can be transmitted to the chest, NOT the reading on the vacuum regulator Air Leak • Water seal is a window into the pleural space • Not only for pressure • If air is leaving the chest through an air leak, bubbling will be seen here • Air meter (1-5) provides a way to “measure” the air leaving and monitor over time – getting better or worse? Assessment • Focused respiratory assessment – Breath sounds – Respiratory rate – Respiratory depth – SpO2 – ABG – CXR Assessment • • • • Cardiovascular assessment Level of consciousness Pain Chest tube & Chest tube system – Be sure you know what is to be assessed Interventions • System position • Tubing position • Connections to patient and system • Monitoring & recording & reporting output Interventions • Dressing changes • Oxygen therapy • Analgesics • IS and turn, cough, deep breathe Complications What are some common complications? Complications & Troubleshooting • Chest tube malposition (most common) • Subcutaneous emphysema • High Fluid in Water Seal Chamber – Chest system may need to be vented – But only if the suction is on • Air leak Others pleural effusion, inc. pneumo, mediastinal shift ? If chest tube comes out? Review • • • • • • Check fluid level in suction chamber Observe water seal chamber fluid level Assess for tidaling in water seal chamber Assess tubing – non dependent Determine if the unit has been knocked over Note the amount, color and consistency of drainage What is most important? • Monitor your client • Notify MD STAT if – Significant drainage – Increasing shortness of breath – Pain – Absence of breath sounds Management • • • • Do not remove suction without an order Manage pain When full - place in biohazard container Do not change collection device on client with an air leak without an order • When suction discontinued, must disconnect from suction, not just turn off Questions • What is the progression of events for discontinuing a chest tube? • Can a patient ambulate with a chest tube?
