1 Oxygenation Assessment and Nursing Interventions
Learn to recognize urgent changes in oxygenation, assess respiratory status and pulse-oximeter findings, and provide and reassess nursing support.
Prioritize respiratory deterioration
Prioritize sudden respiratory deterioration, altered mental status, severe , and signs of poor perfusion. Assess the patient and the trend in their findings; do not rely on a single device reading or wait for a scheduled reassessment when the patient is worsening.
Follow the patient’s prescribed plan, local protocols, and emergency-response procedures. Provide prescribed or protocol-directed support, reassess promptly, and escalate emergencies without delay.
Recognize severe asthma
In a severe asthma attack, a patient who is struggling to speak, using accessory muscles, becoming drowsy, and developing a may have critically limited airflow and be approaching . Treat this as life-threatening deterioration: activate emergency support and provide immediate care within protocol.
Do not delay escalation for a pulse-oximeter reading or a scheduled reassessment. Encouraging coughing and waiting, offering oral fluids, or laying the patient flat are not appropriate responses to this acute deterioration.
Respond to worsening oxygenation
A patient with COPD may have a prescribed oxygen target of during acute care, but the target should be individualized. If a patient whose target is has a reading of on the current oxygen setting and is more breathless than earlier, assess breathing and equipment, promptly escalate the worsening , and adjust oxygen according to the prescription or protocol.
Do not remove or withhold oxygen from a hypoxemic patient, turn it off while waiting for an arterial blood gas result, or defer response until a routine observation. Assess the patient, not just the displayed number.
Interpret pulse-oximeter readings
estimates oxygen saturation, but readings may be affected by poor circulation, skin temperature, skin pigmentation, motion, and nail polish. If the reading does not match the patient’s appearance or reported symptoms, check probe position and signal, reduce motion, and address a cold or poorly perfused hand if possible.
Reassess the patient and consider further clinical evaluation if concern remains. Interpret the reading alongside symptoms, respiratory effort, and the broader clinical picture; do not rely on the value alone, even if it is within the device’s displayed range.
Identify deterioration in respiratory illness
New confusion, rapid breathing, and a falling in an older adult admitted with call for prompt reassessment of respiratory status and vital signs, oxygen support according to protocol, and escalation of the acute change. Do not wait to see whether reorientation resolves the confusion or delay reassessment for walking, food, or fluids.
Increasing sleepiness or confusion during worsening respiratory illness may signal worsening gas exchange or ventilation. may involve low blood oxygen, high carbon dioxide, or both. Confusion, rapid or labored breathing, and altered alertness are concerning; cyanosis is not required before escalating care, and normal-looking skin color does not rule out .
Provide immediate support and escalate
Sudden shortness of breath, pleuritic chest pain, tachycardia, and light-headedness after surgery may indicate a , which can be life-threatening. Initiate urgent medical evaluation, remain with the patient, and assess airway, breathing, circulation, and vital signs. Do not delay care to give oral fluids or assess exercise tolerance by walking.
For a conscious patient with dyspnea, position the patient upright if tolerated, stay with them, assess breathing and oxygenation, and provide prescribed or protocol-directed support. Upright positioning may make breathing easier for some patients. Do not leave the patient to gather supplies, place them flat, encourage prolonged breath-holding, or use sedation instead of assessing the cause of acute respiratory distress.
Reassess the response
After an intervention for dyspnea, reassess the overall clinical picture and the patient’s response. Consider respiratory rate and effort, ability to speak, mental status, breath sounds, vital signs, the trend, and response to treatment.
Do not judge the response by alone, skin color alone, or the patient’s statement that they feel better without checking objective findings. complements, but does not replace, clinical assessment.
