After surgery, patient monitoring is vital to ensure optimal recovery and success of the intervention. Complications can arise that, if not caught quickly, can result in serious consequences for the patient, from slowing down their recovery progress to posing a danger to their health. For cardiac/catheter ablations (scarring a small area of the heart that causes arrythmias1) complications may occur in a minority of cases, so close and continuous monitoring is important to catch them as early as possible.
Measuring respiratory rate (RR) is fundamental for detecting dangerous conditions such as respiratory depression in post-surgical patients. However, the methods used to measure RR can be invasive and intrusive, or overly sensitive and pick up unwanted signals , especially when the patient is active. Measuring RR by monitoring cardiac signals can detect respiratory activity through less invasive and less costly methods than flowmeters or face masks2.
The CardiacSense watch uses sensors which use photoplethysmography (PPG) to measure cardiac and respiratory events. CardiacSense has developed the artifact sensor (ART) that senses the radial artery inflation and deflation (the artery being filled with blood and then emptied). Combining the ART and PPG improves the performance over that of a PPG-only-based signal as the addition of ART compensates for the typical interferences that lead to false alarms: hand and finger motion. This gives the healthcare practitioner a better overview of their patient’s post-ablation status2.
With CardiacSense, these patients can be operated on in a day procedure and then safely monitored with low invasiveness, low energy consumption, and low cost allowing it to be seamlessly integrated in the post-surgical monitoring plan. The Physician portal allows practitioners to consult data and set up personalized alerts, ensuring that any notable signals are picked up as soon as possible.

Using the CardiacSense watch provides peace of mind to both patients and healthcare practitioners post-procedure.
