Associated problems

  • Changes in the alveolo-channel membrane

Suggestions of use

  • This label should be used with caution. The reduction of the passage of gases between the pulmonary alveoli and the vascular system can be discovered only through a diagnostic test requested by a doctor: blood gas analysis. A patient could have most of the defining characteristics without actually suffering a deterioration in the alveolar gas exchange. It is better to use a diagnostic statement that describes oxygen -related problems, so that nursing personnel can diagnose and treat independently (for example, activity intolerance). If the suggested alternative diagnoses are treated, which are stated below, the deterioration of the gas exchange should improve. If the patient is at risk of deterioration of the gas exchange, the proper collaboration problem should be noted (for example, possible complication of thrombophlebitis: pulmonary piston). See the suggestions of use for ineffective cleaning of the respiratory tract, ineffective respiratory pattern and dysfunctional response to the weaning of the respirator.
  • The deterioration of gaseous exchange can be associated with several medical diagnoses. For example, functional lung tissue reduction can be secondary to chronic pneumopathy, pneumonia, thoracotomy, atelectasis, acute respiratory insufficiency syndrome Diaphragmatic mass and hernia. In addition, the reduction of blood supply to the lungs can occur secondary to pulmonary hypertension, pulmonary embolism, congestive heart failure, acute respiratory insufficiency syndrome and anemia.

Suggested alternative diagnostics

  • Activity, intolerance to
  • Ineffective respiratory pattern
  • Dysfunctional ventilatory response to weaning (DVWR)
  • Spontaneous ventilation, deterioration of the
  • Respiratory routes, ineffective cleaning of the

NOC Results

  • Respiratory status: Gaseous exchange: Alveolar exchange of C02 and 0 2 to maintain gase concentrations in blood pressure
  • Tissue perfusion: pulmonary: adequacy of blood flow through the pulmonary vasculature to perfuse the units of the alveoli-channels
  • Response to assisted breathing: adults: alveolar exchange and tissue perfusion are supported by assisted breathing
  • Vital signs: degree in which temperature, pulse, breathing and blood pressure are within normal limits

Evaluation objectives and criteria

  • The respiratory state: gas exchange is not compromised, as evidenced by the following indicators (specify from 1 to 5: severe, substantial, moderate, light or none):
    • Cognitive state Pa02, Paco, arterial pH and saturation of 02 C02 exhaled

  • Respiratory surveillance: Collection and analysis of patient data to guarantee the permeability of the respiratory tract and the appropriate gas exchange

Nursing Activities

Nursing activities for this diagnosis focus on the gaseous exchange in the alveolo-chapila membrane. However, efforts to facilitate ventilation can improve oxygen availability. Other interventions focus on related factors (for example, reduction in anxiety and pain management).
