Respiratory Equipment in Alternative Sites
List and describe the differences between mechanical ventilation in the home and mechanical ventilation in an acute care setting Background Mechanical ventilation provided in the home is drastically different from that delivered in an acute care setting. In an acute care setting such as the hospital, the patient is surrounded by an array of medical equipment and supplies. Specialized health care providers are available at all times to provide diagnostic and therapeutic procedures. In addition, the patient in an acute care setting gets little rest because of frequent vital sign assessments and routine lab tests. An alternative to the acute care setting is to provide mechanical ventilation in a non-acute environment such as the patient’s home. Extension of life is the primary goal of medical and health care procedures. Quality of life is an important issue, for this reason, the patient must be involved in the decision-making process before changing the ventilator care plan from an acute care setting to the patient’s home. When patients require long-term mechanical ventilation beyond the acute care setting, there are many factors that must be considered such as: Indications of need Patient unable to be weaned for invasive support Progression of the disease Contraindications Unstable condition without resources in the home setting Unsafe physical environment Patient non-compliant Non-financial resources Precautions and possible complications Medical problems that return patient to acute status Equipment malfunctions of failure of the ventilator operation Assessment of outcome Determine is indications are present and contraindications are absent Determine if therapy will sustain patient’s life and reduce mortality Monitoring Patient’s physical condition Ventilator settings Equipment function The plan of care Most patients who require ventilator support outside the acute care hospital fall into one of the three broad categories. The patient is unable to maintain adequate ventilation (elevated PaCo2) The patient requires ventilation for survival The patient is terminally ill with a short life expectancy Home Mechanical Ventilation (HMV) HMV requires a detailed discharge plan because it involves many different agencies, departments and caretakers. Before a decision is made to provide HMV for a patient, four needs-assessment questions should be evaluated. The four questions are: Does the patient have a disease state, high cervical spine injury, severe respiratory muscle paralysis, which may result in persistent respiratory failure and an inability to be completely weaned from invasive ventilator support? Does the patient exhibit clinical characteristics (impending respiratory failure, cerebral hypoxia) that require mechanical ventilation? Is the patient clinically stable enough to be managed outside an acute care setting? Are there other noninvasive alternatives besides artificial airway and mechanical ventilation for the patient? Diseases That May Benefit from HMV Chronic obstructive pulmonary disease (COPD) Restrictive lung disease Respiratory muscle dysfunction Central hypoventilation syndromes Invasive versus Noninvasive Ventilation Support Noninvasive ventilation (NIV) is the first choice if the following conditions are met: The patient must be mentally competent, cooperative, and are using limited sedation or narcotics The patient needs minimal amount of oxygen (less than 40%) The patient is able to maintain an oxygen saturation greater than 90% The patient has normal swallowing and airway protection The patient does not have a history of seizures or substance abuse The patient does not have facial trauma Patients who benefit from usually fall into two categories: Conditions that could lead to imminent death Patients with asthma Acute exacerbation of COPD or pulmonary edema Quadriplegia or patients with certain neuromuscular disorders Conditions that do not lead to imminent death Chronic Neuromuscular and chest wall diseases Invasive ventilation is especially used for patients who require long-term pressure ventilation by tracheostomy. This method is associated with potential problems including secretion retention, infection, aspiration, and ventilator-associated pneumonia. The preferred location for long-term mechanical ventilation is in the home, because costs are reduced, quality of life is enhanced, and integration into the community is maximized. The indications for both invasive and noninvasive mechanical ventilation support in the home are increasing as technology and infrastructure support improves; however, reimbursement constraints make it challenging to provide home ventilator patients with the optimal equipment and services required. A central registry would allow for the development and monitoring of national home mechanical ventilator patient outcomes. Equipment The choice of a ventilator is determined by the patient’s clinical need and available support resources. Watch this video on ventilator management.
