Study Notes
Cardiopulmonary Resuscitation (CPR)
- CPR is necessary to restore circulation when oxygen is not delivered to tissues and carbon dioxide is not transported from tissues, leading to tissue metabolism becoming anaerobic and metabolic and respiratory acidosis.
- Permanent heart, brain, and other tissue damage occur within 4 to 6 minutes.
- CPR involves chest compressions, airway opening, breathing, and defibrillation with an automatic external defibrillator (AED).
Respiratory Functioning
- The goal of ventilation is to produce a normal arterial carbon dioxide tension (PaCO2) between 35 and 45 mm Hg and a normal arterial oxygen tension (PaO2) between 80- and 100-mm Hg.
- Hypoventilation and hyperventilation are determined by arterial blood gas analysis.
- Hypoxemia refers to a decrease in the amount of arterial oxygen.
- Nurses monitor arterial oxygen saturation (SpO2) using a noninvasive oxygen saturation monitor pulse oximeter, with a normal value of ≥ 95%.
- Hypoventilation occurs when alveolar ventilation is inadequate to meet the oxygen demand of the body or eliminate sufficient carbon dioxide.
Suctioning
- Open suctioning involves using a new sterile catheter for each suction session, with sterile gloves and following Standard Precautions.
- Closed suctioning involves using a reusable sterile suction catheter encased in a plastic sheath, with nonsterile gloves recommended to prevent contact with splashes from body fluids.
- Prior to suctioning, hyperoxygenate the client using a bag-valve-mask (BVM) or specialized ventilator function with an FiO2 of 100%.
- The nurse suction a small amount of water through the catheter to ensure that the catheter's suction is functioning properly.
- In tracheal suctioning, use suction pressure between 100 and 120 mm Hg as you withdraw, applying suction intermittently only while withdrawing the catheter.
Breathing Exercises
- The three basic techniques are deep-breathing and coughing exercises, pursed-lip breathing, and diaphragmatic breathing.
- Deep-breathing and coughing exercises are routine interventions used by postoperative patients.
- Pursed-lip breathing involves deep inspiration and prolonged expiration through pursed lips to prevent alveolar collapse.
- Diaphragmatic breathing is a deep breathing exercise that fully engages the diaphragm and increases the efficiency of the lungs, improving ventilation and oxygenation.
Diagnostic Tests
- Tests used for cardiopulmonary functioning include blood specimens (ABGs), X-rays of the organs, and TB skin testing.
- Airway Management involves maintaining a patent airway, mobilizing secretions, suctioning the airway, and managing artificial airways (mechanical or assisted ventilation) to promote adequate gas exchange and lung expansion.
Oxygen Therapy
- The goal of oxygen therapy is to prevent or relieve hypoxia by delivering oxygen at concentrations greater than ambient air (21%).
- Supplemental oxygen therapy offers many benefits to patients with chronic cardiopulmonary diseases.
- Oxygen is supplied to a patient's bedside either by oxygen tanks or through a permanent wall-piped system.
- FiO2 is the fraction (0.21) or percentage (21%) of inspired oxygen, with supplementation oxygen raising FiO2 above 21%.
Oxygen Delivery Methods
- Oxygen delivery methods include nasal cannula, simple face mask, partial rebreather mask, non-rebreather (NRB) mask, Venturi mask, and tracheostomy collar.
- Each method has a specific FiO2 delivery range and flow rates.
- Nursing actions involve monitoring the patient for signs of changes in cardiopulmonary functioning, such as sudden shortness of breath, pain, oxygen desaturation, and anxiety.
Respiratory Function Nursing Diagnoses
- Nursing diagnoses include Ineffective airway clearance, Ineffective breathing patterns, Impaired gas exchange, Decreased cardiac output, Ineffective tissue perfusion, and other associated diagnoses.
- Nursing actions involve sputum specimen collection, offering mouth care, and rinsing with water prior to obtaining the sample.
