States Contraindications and Relative Contraindications of procedure.

|
|
| Preparation |
| Clinical Standards for Procedures and Interventions. |
|
|
| Confirms the clinical indication, informed-consent requirements, authorized protocol, trained personnel, emergency support, and specimen-handling instructions. |
|
|
| Performs a documented risk assessment for airflow obstruction, cardiopulmonary instability, hemoptysis, inability to protect the airway, recent relevant surgery, and other procedure-specific hazards. |
|
|
| Uses the designated aerosol-generating-procedure environment, ventilation controls, personal protective equipment, and room turnover process required for the suspected pathogen and facility policy. |
|
|
| Assessment |
| Obtains baseline symptoms, respiratory rate, heart rate, oxygen saturation, breath sounds, and FEV1 or peak expiratory flow when feasible and required by protocol. |
|
|
| Preparation |
| Administers bronchodilator pretreatment when indicated by the risk assessment or protocol and confirms recovery or stability before saline nebulization. |
|
|
| Prepares the protocol-specified sterile isotonic or hypertonic saline, approved nebulizer, sterile leak-proof specimen container, labels, rescue medications, oxygen, and monitoring equipment. |
|
|
| Implementation |
| Collects a spontaneous deep-cough specimen first when possible, then administers saline in the concentration, duration, and stepwise sequence specified by the validated protocol. |
|
|
| Coaches deep breathing and effective coughing and collects lower-airway sputum rather than saliva into the sterile container without contaminating the exterior. |
|
|
| Monitoring & Modifications |
| Monitors symptoms, oxygen saturation, respiratory rate, heart rate, breath sounds, and FEV1 or peak expiratory flow at protocol-defined intervals and after bronchodilator rescue. |
|
|
| Stops the procedure and provides appropriate treatment for clinically significant airflow decline, bronchospasm, respiratory distress, desaturation, chest pain, syncope, severe dizziness, or hemoptysis. |
|
|
| Post-Intervention |
| Seals, labels, and transports the specimen promptly according to laboratory and biohazard requirements and records whether the sample appears to be sputum rather than saliva. |
|
|
| Completes room-air clearance, equipment disposal or reprocessing, hand hygiene, post-procedure reassessment, and documentation of saline dose, duration, lung-function change, adverse effects, and specimen disposition. |
