## Abstract

Systems, methods, and apparatuses for treating a tissue site are described. In some embodiments, the system may include a dressing, a negative-pressure source, and a communication device. The communication device may be coupled to the negative-pressure source and configured to transmit operational data of the negative pressure source to a remote location for monitoring usage of the system.

## Claims

### Claim 1

A method for treating a tissue site, comprising:
activating a negative-pressure source configured to provide negative pressure to the tissue site;
transmitting data related to a usage time of the negative-pressure source to a remote user;
determining that the usage time is less than a threshold value, wherein the threshold value is in a range of 16 hours/day to 19 hours/day;
generating an alert to signal that the usage time is less than the threshold value and to prompt the remote user to contact a user of the negative-pressure source.

### Claim 2 (depends on 1)

The method of claim 1, wherein the threshold value is in a range of about 17 hours/day to 18 hours/day.

### Claim 3 (depends on 2)

The method of claim 2, wherein the threshold value is about 17 hours/day.

### Claim 4 (depends on 1)

The method of claim 1, wherein the usage time is an average number of hours per day from two or more days.

### Claim 5

A system for monitoring negative-pressure therapy, comprising:
a negative-pressure therapy unit;
a dressing fluidly coupled to the negative-pressure therapy unit;
a communication device coupled to the negative-pressure therapy unit and configured to transmit operational data of the negative-pressure therapy unit; and
a receiving unit configured to receive operational data transmitted from the communication device, wherein the receiving unit comprises a processor configured to process the operational data to provide an output determination of whether a usage time of the negative-pressure therapy unit meets a threshold value, wherein the threshold value is in a range of 16 hours/day to 19 hours/day.

### Claim 6 (depends on 5)

The system of claim 5, wherein the threshold value is in a range of about 17 hours/day to 18 hours/day.

### Claim 7 (depends on 6)

The system of claim 6, wherein the threshold value is about 17 hours/day.

### Claim 8 (depends on 6)

The system of claim 6, wherein the threshold value is about 18 hours/day.
