Safety Norms: Pulmonology, Respiratory and Sleep Medicine

11. Purpose, Scope, and Safety Principles

These norms apply to physicians, nurses, respiratory therapists, pulmonary function technologists, sleep technologists, and support staff who assess, investigate, treat, or monitor patients with lung disease, airway disorders, breathing control problems, and sleep-related breathing conditions. They cover outpatient clinics, inpatient wards, bronchoscopy and procedure suites, pulmonary function laboratories, sleep laboratories, and home respiratory services.

Three principles guide everything here. Patient safety comes first, the least invasive effective option is preferred, and any uncertainty triggers escalation rather than improvisation.

• Mandatory: every patient encounter begins with identity verification and a documented reason for the test or treatment.
• Mandatory: no test, procedure, or therapy starts without an authorized clinician's order or an approved local protocol.
• Recommendation: use a structured deterioration tool, such as an early warning score, where your organization has adopted one.

22. Roles, Competence, and Accountability

The responsible physician or licensed practitioner owns the diagnosis, the order, and the overall treatment plan. Each staff member is accountable for working within their authorized scope and for raising concerns. Scope of practice is defined by licensing rules, employer credentialing, and local delegation policies. These vary by jurisdiction and must be verified locally.

Accountability works in both directions. Staff who identify an unsafe order, missing equipment, or a patient who does not fit the protocol must pause the activity and inform the responsible clinician. No one should be penalized for a good-faith safety report.

• Mandatory: staff perform only tasks within their credentialed scope, such as spirometry, polysomnography setup, or non-invasive ventilator checks where authorized.
• Mandatory: bronchoscopy, chest tube management, tracheostomy care, and invasive airway procedures are performed only by individuals with documented credentials and the supervision required by local policy.
• Mandatory: a named supervising clinician must be reachable during any study or procedure involving sedation, continuous monitoring, or ventilatory support.
• Recommendation: keep a competency log for each technique and review it periodically with the supervising clinician.

33. Course-Specific Hazards and Risk Assessment

Pulmonology work combines infection risk, airway emergencies, sedation effects, oxygen and gas hazards, and sleep-related safety issues. A risk assessment must be documented for each service and reviewed when activities, equipment, or staffing change. Rate each hazard as low, medium, or high based on likelihood and severity, then assign a named control and an owner.

Risk ratings in this section are indicative only. Local risk registers and occupational health advice should set final ratings.

• Airborne and droplet transmission from patients with suspected or confirmed respiratory infection, especially during sputum induction, bronchoscopy, and nebulized treatments (high).
• Aerosol generation during cough-inducing tests, spirometry with infection concerns, and high-flow therapy (high).
• Airway compromise, bronchospasm, hypoxemia, or carbon dioxide retention during testing or procedures (high).
• Respiratory depression from sedation or anesthesia used for bronchoscopy or sleep-related testing (high).
• Oxygen fire risk from oils, grease, cigarettes, and open flames near oxygen equipment (high).
• Ventilator alarms, disconnected tubing, or incorrect filter placement causing inadequate delivery (high).
• Pressurized cylinder hazards, including falls, damaged regulators, and gas mix-ups (medium).
• Trips over cables and tubing in sleep laboratories and during home visits (medium).
• Drowsy driving after overnight studies, and night-time falls by patients with sleep disorders (medium).
• Skin or respiratory irritation from disinfectants and reprocessing chemicals used on scopes and test equipment (medium).

44. Preventive Controls and Safe Work Practices

Preventive controls follow the hierarchy of elimination, substitution, engineering controls, administrative controls, and personal protective equipment. Favor engineering and administrative controls such as airborne isolation rooms where available, closed suction systems, and scheduling that limits exposure. Personal protective equipment is the last line of defense, not the only one.

Hand hygiene is required before and after every patient contact. Respirator use, fit testing, and isolation precautions must follow the local infection prevention policy. Reusable scopes and lung function equipment must be reprocessed according to manufacturer and facility instructions by trained staff, with records kept.

• Mandatory: screen every patient for infection symptoms and exposure history before scheduling aerosol-generating procedures, using the local triage tool.
• Mandatory: perform bronchoscopy, induced sputum collection, and similar procedures only in rooms approved for aerosol-generating work, with ventilation confirmed against local policy.
• Mandatory: before any sedation, confirm fasting status, allergies, current medicines, and airway risk assessment as required by the local sedation policy.
• Mandatory: check suction, bag-valve-mask or equivalent resuscitation equipment, and emergency medicines specified by local policy before each procedure or monitored study.
• Mandatory: use continuous pulse oximetry and, where the protocol requires it, capnography, with alarm limits set by the responsible clinician rather than factory defaults alone.
• Mandatory: check ventilator and CPAP circuits for leaks, disconnections, and correct filters before each patient use, following manufacturer instructions.
• Mandatory: do not change prescribed oxygen, ventilator, or pressure settings unless the order or protocol allows it, and document every change.
• Mandatory: post no-smoking and no-open-flame signs in oxygen areas, and keep cylinders upright, secured, and capped when not in use.
• Recommendation: use a standard pre-procedure checklist covering equipment, consent confirmation, team roles, and a named escalation contact.

55. Consent and Patient Communication

Informed consent is required before diagnostic tests, procedures, sedation, and invasive therapies unless law or an approved emergency policy permits otherwise. Consent must be voluntary and based on information the patient can understand. Explain the purpose, the main risks such as bleeding, a collapsed lung (pneumothorax), sedation effects, or breathing changes, the alternatives, and what happens if the patient declines.

Confirm decision-making capacity and identify any legally authorized representative. Use interpreters or accessible formats where needed. A patient may withdraw consent at any time, and the procedure must stop unless an emergency protocol applies. Consent rules for minors and dependent adults are jurisdiction-dependent and must be verified locally.

• Mandatory: use the consent form version currently approved by the organization.
• Mandatory: the performing clinician, or a delegated and trained clinician, obtains consent. Support staff must not obtain consent for procedures they cannot fully explain.
• Recommendation: give written information on home oxygen or sleep study plans, including who to contact if problems occur.

66. Equipment, Environment, Information, and Privacy

Equipment must be inventoried, labeled, serviced, and removed from use when faulty. Spirometers, gas analyzers, polysomnography systems, and ventilators require checks and servicing according to manufacturer instructions and local biomedical engineering requirements. This document does not set those intervals.

Respiratory and sleep records contain diagnoses, imaging, smoking and occupational exposure history, breathing recordings, and sometimes video. Treat these as sensitive health information. Access is limited to people with a care or operational need. Do not store images or recordings on personal devices or send them through unapproved messaging apps. Privacy and data protection obligations are jurisdiction-dependent, so confirm them with your records office.

• Mandatory: tag out faulty equipment immediately and report it to biomedical engineering.
• Mandatory: store medical gases separately from flammable materials and secure cylinders in racks or carts.
• Mandatory: clean and disinfect masks, sensors, and tubing between patients using approved products and the contact time stated on the label.
• Mandatory: share patient recordings only with authorized clinicians and only through approved systems.
• Recommendation: provide sleep laboratory patients with guidance on lighting, noise, bed exit safety, and how to call for help.

77. Incident, Near-Miss, Emergency, and Escalation Procedures

Report all incidents, near misses, equipment faults, and unexpected clinical events through the organization's reporting system within the timeframe set by local policy. Immediate patient safety actions always come first. Staff must never delay life-sustaining care to complete paperwork.

Escalation is expected, not optional. Escalate when breathing worsens, when oxygen or ventilation targets are not met despite the protocol, when equipment fails, or when a staff member feels out of their depth. Call emergency services directly for an immediate life threat. This document does not replace emergency medical services or local emergency procedures.

• Mandatory: for suspected respiratory failure, severe bronchospasm, airway obstruction, or unresponsiveness, activate the emergency response team and start the local resuscitation protocol.
• Mandatory: for a suspected pneumothorax, heavy bleeding from the airway, or sedation complications, stop the procedure as directed by the proceduralist and follow the emergency pathway.
• Mandatory: for a suspected oxygen-related fire, shut off the oxygen supply if trained and safe to do so, move the patient away, and follow fire procedures.
• Mandatory: notify infection prevention and occupational health as soon as practical after a suspected exposure or cluster of infections.
• Mandatory: follow the local safeguarding procedure for suspected abuse, neglect, or self-harm.
• Recommendation: hold a brief debrief after significant events and share lessons through the safety committee.

88. Documentation, Training, Monitoring, and Review

Good records show what was ordered, what was done, who did it, how the patient responded, and what changed. Document consent, sedation, oxygen and ventilator settings, alarm responses, incidents, and equipment checks. Correct errors using local amendment rules rather than erasing or overwriting entries.

Review this document and local procedures when guidelines, equipment, laws, or incident findings change. Check professional society guidance and regulator requirements for current versions. Treat every statement here as a starting point, not final authority.

• Mandatory: complete initial training in infection prevention, emergency response, oxygen safety, and equipment use before working unsupervised.
• Mandatory: a supervisor verifies and records each staff member's competence before they perform independent tasks.
• Recommendation: run simulation drills for airway emergencies and deterioration at intervals set by the local safety committee.
• Recommendation: audit documentation, alarm response, cleaning, and hand hygiene, and revise protocols based on the findings.

Implementation checklist

• Confirm identity, the order, and valid consent before every test or procedure.
• Verify your credentialed scope and the supervising clinician's availability before starting.
• Screen for infection risk and apply the required respiratory precautions.
• Check oxygen, suction, resuscitation equipment, and monitors before use.
• Keep oxygen away from ignition sources and secure all cylinders.
• Confirm the sedation risk assessment and monitoring plan are documented.
• Protect recordings and records, and share them only with authorized people.
• Escalate early when breathing, oxygen, or equipment problems arise.
• Report incidents and near misses within the local timeframe.
• Verify current laws, standards, and manufacturer instructions with competent authorities.
