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

Pleural Anatomy Parietal pleura Visceral pleura Normal Pleural Fluid Quantity: Approx mL per lung Lung RibsIntercostal muscles

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

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: Prevent Air and Fluid Backflow Tube open to atmosphere vents air 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 Collection chamber Water seal chamber Suction control chamber from patient Suction control bottle Water seal bottle Collection bottle From patient To suction

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?
