Guidelines for Ventilator Management

Overview

Introduction
  • A mechanical ventilator is a machine that helps people breathe when they are not able to breathe enough on their own. Also called a respirator or breathing machine, a ventilator is used to:
    • get oxygen into the lungs and body
    • help the body get rid of carbon dioxide through the lungs
    • ease the work of breathing—some people have difficulty breathing on their own
    • breathe for a person who is not breathing because of injury to the nervous system, like the brain or spinal cord or who has very weak muscles.
  • This policy aims to ensure:
    • evidenced-based standards of care are provided for safe and efficient management of mechanically ventilated clients 
    • the needs, comfort and goals set for the patient with an acute ventilator or respiratory failure are met 
    • every patient requiring ventilator management receives appropriate support relevant and proportionate to their individual needs and the specific ventilator used.
  • When a person breathes normally (spontaneous breathing), the diaphragm contracts on inhalation, moving toward the abdomen, and the chest wall expands. The space inside the thorax enlarges creating a vacuum that draws air into the lungs and helps to distribute the air evenly. In contrast, a ventilator pushes a warm, humidified mixture of oxygen and air into the lungs and creates positive pressure in the thorax during inhalation. 
  • The correct care of a person who relies on mechanical ventilation is critical as they are at a greater risk of death or harm if inadequate or inappropriate care is provided. Key managers must ensure carers follow this policy and that clients have person-centred ventilation management plans.
Assessment
  • As part of the service entry process, a detailed assessment is required for a client with ventilation needs. 
    • Family presence is recommended for the assessment meeting for additional information and support. 
    • This is especially important when verbal communication is difficult. 
    • It is important to determine the level of care required. 
  • Close liaison should be maintained with the multidisciplinary team including specialist nurses, physiotherapists, speech therapists and doctors. 
    • A coordinated team approach is the best practice for this specialised area of care.
  • There must be a documented plan for assessment, management and review for each individual client using a ventilator. 
    • The type of detail to evaluate at initial assessment includes, but are not limited to, the following:
      • client history—the level of self-care management the client is able to: 
        • learn the ventilator settings and understand what the alarm might mean 
        • can they change their own tube? 
        • how well are they able to clear their own secretions by coughing? 
        • can they swallow?
    •  if they have a tracheostomy?
    • if they have a larynx?
    • do they have a connection between the oral airway and lungs?
    • communication strategy e.g. verbal, non-verbal, pen and paper, communication board or voice synthesiser
    • type and size of the tracheostomy tube and when a routine change of tube is required
    • oxygen dependence
    • how often is suction required
    • routine observations.
Risks of mechanical ventilation
  • There are many problems that can develop from ventilator use including:
    • infections such as pneumonia—the ET or trach tube allows bacteria to get into the lungs more easily
    • collapsed lung (pneumothorax)—a part of a lung that is weak can become too full of air and start to leak into the chest wall which causes the lung to start to collapse
    • lung damage—the pressure of putting air into the lungs with a ventilator can damage the lungs—this is why health professionals should set the ventilator to the lowest amount of pressure needed
    • side effects of medications—sedatives and pain medications can cause a person to seem confused or delirious while other medications to prevent muscle movement can cause muscle weakness
    • inability to stop using ventilator support—if a person’s conditions do not improve, long term reliance on ventilation may be required.
Monitoring
  • People who rely on mechanical ventilation often require monitoring. 
    • Devices for monitoring include pulse oximeter (measures oxygen level and heart rate) or apnea monitor (measures heart rate and breathing rate). 
  • The client’s medical practitioner will determine the need for monitoring and what ventilation adjustments are required.
Applies
  • when clients are supported who require mechanical ventilation
  • to all HWH employees and key managers supporting clients with mechanical ventilation needs

Policy

Ventilator management guidelines
As a guide:
  • clients requiring ventilation will only receive support from workers trained and proficient in ventilator management
  • ventilator and bedside alarms must be on at all times—never leave a client unattended with alarms turned off
  • suction equipment, oxygen, and manual ventilation device (MVD) and masks must be readily available at the bedside of all clients with artificial airways
  • intubation supplies must be readily accessible for all patients with artificial airways
  • the decision to wean a client from ventilation support should only be made by a qualified health professional
  • maintain all ventilatory and monitoring equipment according to the manufacturer’s instructions at all times in order to reduce the risk of failure.
Ventilator management responsibilities of carers
  • Clients that rely on ventilation are at greater risk of pneumonia (chest infection). Providers are responsible to care for and ensure clients are safe. 
  • This includes carers to:
    • read and understand this policy before providing support to ventilated clients 
    • complete all required competencies and training before providing support to ventilated clients
    • work within their scope of practice and qualifications
    • wear appropriate PPE at all times
    • be competent in setting appropriate alarm settings
    • respond immediately to an audible ventilator alarm and assess the client for respiratory distress or a disconnected ventilator
    • suction as required both orally and via the artificial airway
    • ensure the securement device goes around the head/neck and is comfortable for the patient
    • follow instructions of the responsible clinician which include: 
      • set up of the mechanical ventilator, accessories and tubing specific to the client's needs 
      • set up of in-line suction for ventilated clients 
      • how to initiate ventilation, set the alarms and provide adjunctive ventilator equipment 
      • setting the ventilation parameters based on the client's ideal body weight and medical condition 
      • adjusting ventilator settings in conjunction with the medical practitioner’s orders 
      • monitor the ventilator and patient after setting changes and after re-initiating ventilator i.e. post transport 
    • be knowledgeable of current and prescribed ventilator settings
    • follow the medical practitioner’s orders and ventilator setting change requests
    • communicate medical practitioner’s orders promptly with other relevant team members
    • assess the client at regular intervals as directed by a medical practitioner
    • collect blood gases if ordered and the arterial line is present.
    • Report any changes in the client's condition, e.g.cyanosed lips or finger nails.
Key management responsibilities when supervising clients supporting clients with ventilators
  • Responsibilities of supervisors are to:
    • ensure carers have current knowledge and a training plan to learn the standards of care for clients that require mechanical ventilation
    • provide carers education to provide excellent and confident care
    • ensure carers follow and comply with the Manage ventilator process
    • ensure carers know how to activate emergency support
    • ensure emergency airway equipment is available at all times including resuscitation bag and airway equipment
    • ensure supervisors have accreditation in Basic Life Support
    • regularly audit safe ventilator management practices
    • document all ventilator-related interventions, assessments and care provided in an observation chart including any abnormal findings
    • consider whether the participant needs physical restraints to prevent accidental removal of the ETT/tracheostomy tube.
Documentation
  • Carers must keep clear and legible records on the clients with ventilators. 
  • This should include:
    • type, size and location of airway
    • level of an endotracheal tube (ETT) at the teeth/gum once a shift, after any adjustments and daily in any case
    • ventilator settings at the onset of the shift, q4h and with any change in orders or patient’s condition
    • SaO2 and ETCO2 quarter-hourly and with any change in orders or client's condition
    • amount, consistency and colour of tracheal secretions after each suction session on the flowsheet
    • unexpected outcomes and interventions.
