## Abstract

The disclosure pertains to a perfusion system that is easy to set-up, use and monitor during a bypass procedure. In some embodiments, the disclosure pertains to a perfusion system in which at least some of the disposable components used with the perfusion system are configured to be able to communicate set-up and/or operational parameters to the perfusion system. In some embodiments, the disclosure pertains to a blood level sensor that can be used to monitor a blood level or volume within a blood reservoir. The blood level sensor may be utilized in an integrated perfusion system in which the disposable components are configured, as noted above, to communicate with the perfusion system. In some embodiments, the blood level sensor may be utilized with a perfusion system lacking communication with disposables.

## Claims

### Claim 1

A method of configuring an integrated perfusion system including a heart lung machine having an RF sensor and a disposable component having an RFID tag, the method comprising steps of:
attaching the disposable component having an RFID tag to the heart lung machine;
reading the RFID tag with the RF sensor; and
configuring operation of the heart lung machine based at least in part upon information provided from the RFID tag to the RF sensor.

### Claim 2 (depends on 1)

The method of claim 1, wherein reading the RFID tag with the RF sensor comprises scanning a passive RFID tag with an RF reader.

### Claim 3 (depends on 1)

The method of claim 1, wherein configuring operation of the heart lung machine comprises providing a controller with the information provided from the RFID tag to the RF sensor.

### Claim 4 (depends on 1)

The method of claim 1, further comprising displaying information provided from the RFID tag to the RF sensor.

### Claim 5 (depends on 1)

The method of claim 1, wherein attaching the disposable component having an RFID tag to the heart lung machine precedes reading the RFID tag with the RF sensor.

### Claim 6

A heart lung machine pack comprising:
a housing configured to hold a plurality of disposable elements for a heart lung machine;
a tubing set having a first RFID tag secured to the tubing set, the tubing set configured for one-time use with a heart lung machine; and
a component having a second RFID tag secured to the component, the component configured for one-time use with a heart lung machine.

### Claim 7 (depends on 6)

The heart lung machine pack of claim 6, wherein the component having an RFID tag secured thereto includes one or more of a venous blood reservoir, a suction blood reservoir, a vent blood reservoir, a combined blood reservoir, an oxygenator, a heat exchanger or an arterial filter.

### Claim 8 (depends on 6)

The heart lung machine pack of claim 6, wherein the first RFID tag includes readable information relating to volumetric parameters of the tubing set.

### Claim 9 (depends on 6)

The heart lung machine pack of claim 6, wherein the second RFID tag includes readable information relating to performance parameters of the component.

### Claim 10 (depends on 6)

The heart lung machine pack of claim 6, wherein the first RFID tag and the second RFID tag each comprise a passive RFID tag.

### Claim 11 (depends on 6)

The heart lung machine pack of claim 6, wherein the housing includes a third RFID tag that includes readable information identifying the contents of the heart lung machine pack.
