Insights
The RRa sensor accurately monitored respiratory rate in a pediatric patient post-surgery. This acoustic device shows promise for respiratory monitoring in intensive care settings.
Area of Science:
- Anesthesiology
- Biomedical Engineering
- Pediatric Critical Care
Background:
- Respiratory rate monitoring is crucial for pediatric patients, especially post-surgery.
- Existing monitoring methods may have limitations in pediatric intensive care.
- The RRa sensor is a novel acoustic device for respiratory rate measurement.
Observation:
- The RRa sensor was applied to a 10-year-old male pediatric patient post-adenotonsillectomy.
- Respiratory rate was continuously monitored during transfer to the Pediatric Intensive Care Unit (PICU).
- The sensor accurately measured respiratory rate even when the patient was sedated with dexmedetomidine in the PICU.
Findings:
- The RRa sensor successfully measured the respiratory rate in a pediatric patient under general anesthesia and sedation.
- Continuous monitoring was achieved from the operating room to the PICU.
- The device demonstrated accuracy in a challenging clinical environment.
Implications:
- The RRa sensor shows potential as a non-invasive tool for respiratory monitoring in pediatric surgical patients.
- This technology could enhance patient safety and management in the PICU.
- Further studies are warranted to validate the RRa sensor's efficacy in diverse pediatric populations.
Abstract:
Rad-87 and RRa are new acoustic monitoring devices which can monitor the respiratory rate. To our knowledge, no studies have reported the RRa sensor used in pediatric patients after surgery. We succeeded in measuring the respiratory rate with the RRa sensor in the Pediatric Intensive Care Unit(PICU). A 10-year-old boy, 14.5 kg in weight and 119.6 cm in height, with cerebral palsy, mental retardation, epilepsy, and obstructive sleep apnea due to adenoidal and tonsillar hypertrophy, was scheduled for adenotonsillectomy under general anesthesia. Anesthesia was maintained with oxygen, air, sevoflurane (1.5-2.0%), remifentanil (0.1 to 0.5 microg . kg-1. min-1), and fentanyl (4 microg . kg-1). The operating time was 55 minutes, and the duration of anesthesia was 133 minutes. After finishing the surgery, we attached the RRa sensor to his anterior neck and monitored his respiratory rate. Furthermore, RRa could count his respiratory rate, during transfer from the operating room to PICU. The patient was sedated with dexmedetomidine (0.28 microg . kg-1 . min-1) at PICU, and his respiratory rate was accurately measured with the RRa sensor. We hope that Rad-87 and RRa sensors will become useful for measuring the respiratory rate in pediatric patients in the future.

Assessment of apical radial pulse
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.

Assessment of Ventilation I: Respiratory Rate
A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.
Critical Guidelines for Assessing Ventilation:
