Indications for Use

The EarlySense Chair Sensing Unit is intended to be used for continuous measurement of Respiration Rate, Heart Rate and Movement, in an automatic contact-less manner, at home, hospital or clinic setting. The sensor is indicated for use in children, adolescents and adults. The operation of the EarlySense system has been studied in children (weight ≥ 10 Kg) and adults (weight <111 Kg) during sleep and resting condition. The Chair Sensing Unit can be used with bedside units that contain appropriate software (graphical interface) that can support reading and displaying EarlySense Chair Sensing Unit readings. In addition, the EarlySense System can continuously monitor oxygen saturation of arterial hemoglobin (Sp02) using pulse oximetry in pediatric (ages 2 years and older), adolescents and adults at home, hospital, or clinical settings.

Device Story

Chair Sensing Unit is a contactless accessory for EarlySense bedside units; monitors heart rate, respiration rate, and movement. Device consists of piezoelectric elements in a plate, housed within a foam cushion. Patient sits on cushion; sensor detects mechanical signals (cardioballistic effect, breathing, body movement) without direct skin contact. Signals converted to electrical, filtered, and transmitted to bedside unit. Bedside unit software processes signals to compute and display physiological parameters. Used in home, hospital, or clinic settings; operated by clinicians or patients. Provides continuous monitoring to assist healthcare providers in patient assessment; enables non-invasive tracking of vital signs during rest.

Clinical Evidence

Bench testing only. Performance evaluated using physiological signal simulators to compare Chair Sensing Unit output against predicate Bed Sensing Unit. Environmental testing included random and sinusoidal vibration assessments to ensure functionality. No clinical human trials were required for this accessory submission.

Technological Characteristics

Piezoelectric sensor elements; accelerometer; piezofilm. Components housed in foam cushion. Connectivity: wired to bedside unit. Sensing principle: conversion of mechanical signals (cardioballistic, respiratory, movement) to electrical signals. Software-based signal analysis performed at the bedside unit. No specific material standards or software architecture class provided.

Indications for Use

Indicated for continuous monitoring of respiration rate, heart rate, and movement in children (≥10 kg), adolescents, and adults (<111 kg) in home, hospital, or clinic settings during sleep or rest. Also indicated for SpO2 monitoring in pediatric (≥2 years), adolescent, and adult populations.

Regulatory Classification

Identification

A breathing (ventilatory) frequency monitor is a device intended to measure or monitor a patient's respiratory rate. The device may provide an audible or visible alarm when the respiratory rate, averaged over time, is outside operator settable alarm limits. This device does not include the apnea monitor classified in § 868.2377.

of arterial hemoglobin (Sp02) using pulse oximetry in pediatric (ages 2 years and older), adolescents and adults at home, hospital, or clinical settings. .

### Device Description

EarlySense is submitting a new accessory for contactless measurement of heart, respiratory rate and motion, the Chair Sensing Unit. The Chair Sensing Unit, similar to its predicate, the EarlySense Bed Sensing Unit cleared as part of previous EarlySense system submissions (K070375, K082465, K092062, K120465), is intended for continuous measurement of Heart Rate, Respiration Rate and motion while the patient is resting.

The EarlySense Chair sensing unit is comprised of the following components:

1. Sensor: that includes piezoelectric elements incorporated into a plate

2. A cushion made of foam into which the sensor is inserted into - so not to be touched by the patient.

The Chair sensing unit should be connected to a bedside unit that receives and analyzes the signals from the Chair sensing unit to measure and display heart rate, respiratory rate and motion.

# Similarities and differences in technological characteristics of Chair Sensing Unit and Bed Sensing Unit (predicate)

#### Similarities:

- Similar piezoelectric sensor is used.

-The sensor performs similar functions as the Bed Sensing Unit does

-The way of receiving, analyzing, sampling and sending signals to the Bedside unit is similar to its predicate, Bed Sensing Unit

{3}------------------------------------------------

#### Differences:

-Accelerometer, rod and additional piezoelectric sensor (piezofilm) were added to the Chair Sensor

-Chair Sensor is placed under a specially-designed cushion, in order to avoid the direct contact between the patient and the sensor and to achieve the correct positioning of the sensor on the chair.

### Substantial Equivalence

The EarlySense Chair Sensing Unit is similar to its predicate, the EarlySense Bed Sensing Unit. It has similar intended use and indications for use. The fundamental technology and mode of operation of the Chair sensing unit are similar as those of the Earlysense Bed Sensing unit. Similar to the cleared Bed Sensing Unit that is placed under the bed mattress and does not contact the patient, the Chair sensor is inserted into a specific cushion that mimics the bed mattress, so the chair sensor does not touch the patient. The Chair Sensing Unit performs similar functions as the Bed Sensing unit-in a contactless manner it monitors heart, respiration rate and motion. Similar to its predicate, the Earlysense Bed Sensing unit, the mechanical signals that are detected by the piezoelectric element of the sensors (Bed or Chair) are converted into an electric signal, which is then sampled and filtered and transferred to the EarlySense Bedside Unit, in order to be analyzed by the System's software to provide the respiration rate (RR), heart rate (HR), and movement rate. The system's detection algorithms differentiate between large body movements, breathing movements and the cardioballistic effect, and thus compute the continuous heart and respiration rates and the body movement.

The presented additional accessory, Chair Sensing Unit has similar functionality, the similar indications for use, technology, mode of operation and performance specifications as the Bed Sensing Unit.

# Verification and Validation Activities:

The Chair Sensing Unit was subject to the following verification and validation tests to ensure correct performance:

1. Risk analysis

2. Bench Testing:

- Performance tests were performed with signals simulating physiological patient signals to evaluate the measurement and compare those to the predicate device to show equivalent performance.

- Theoretical assessment and bench tests were performed to assess the magnitude and effect of external sources of vibration and their effect on the chair sensing unit's functionality.
- Environmental testing including: Random vibration (Non-Operational test), Sinusoidal vibration (Variable Frequency Operational)

3. Complete software verification and validation testing performed to ensure proper functionality.

In addition, the Chair Sensing Unit as part of the EarlySense System was subject to complete set of testing (electrical safety, EMC and environmental testing) to ensure proper functionality.

The results of the bench tests showed, that the signals as detected by the chair sensing unit are similar to those that are detected by the predicate EarlySense Bed Sensor and thus the performance of the Chair Sensing Unit is equivalent to the performance of the Bed Sensing Unit and the performance of the chair sensor is not affected by the new design that includes insertion of the sensor into a cushion (rather than insertion of the sensor under a bed mattress). Therefore, it was concluded that the Chair Sensing Unit may be considered to be substantially equivalent to the previously cleared EarlySense Bed Sensing Unit (K120465).
