Total depreciation expense related to our property and equipment was $0.1 million and $0.2 million for the three months ended September 30, 2022 and 2021, respectively. Depreciation expense for the nine month periods ended September 30, 2022 and 2021 was $0.5 million and $0.7 million, respectively.

Total depreciation expense related to devices out on lease was $0.3 million and $0.4 million for the three months ended September 30, 2022 and 2021, respectively. Depreciation expense related to devices out on lease was $1.0 million and $1.0 million for the nine months ended September 30, 2022 and 2021, respectively. Depreciation on leased units is reflected in the condensed consolidated statements of operations as cost of revenue.

The Company monitors devices out on lease for potential loss and places an estimated reserve on the net book value based on an analysis of the number of units which are still with patients for which the Company cannot determine the current status.
