## Abstract

A patient monitoring system includes sensors, a patient support assembly, and a gateway device and/or control module. Example sensors include physiological sensors and patient status devices. The sensors acquire patient-related data. Patient related action is determined based on the patient-related data.

## Claims

### Claim 1

A patient monitoring and support system, comprising:
a patient support assembly configured to support a patient;
a patient status device configured to obtain patient status data; and
a control module including:
a processing unit; and
memory having stored thereon instructions that, when executed by the processing unit, cause the control module to:
receive the patient status data from the patient status device;
analyze the patient status data to determine a condition of the patient;
based on the condition of the patient, adjust an alarm setting, including to prioritize alarms when the patient status data indicates a change in the condition of the patient;
based on the change in the condition of the patient, adjust a position of the patient support assembly, the position of the patient support assembly being a head-of-bed angle; and
further adjust the alarm setting, including to adjust one or more alarm limits as a function of the head-of-bed angle.

### Claim 2 (depends on 1)

The patient monitoring and support system according to claim 1, wherein the patient status data is selected from the group consisting of: vital sign data, patient diagnosis data, patient treatment data, patient position data, patient movement data, patient history data, patient demographic data, patient alarm data, and pharmacological data, and
wherein the control module is configured to adjust the alarm setting based on the pharmacological data.

### Claim 3 (depends on 2)

The patient monitoring and support system according to claim 2, the memory further storing instructions that, when executed by the processing unit, cause the control module to determine based on the vital sign data, whether the patient is experiencing a side effect associated with overmedication.

### Claim 4 (depends on 1)

The patient monitoring and support system according to claim 1, wherein the patient status data includes patient movement data;
wherein the control module is configured to adjust the alarm setting by holding an alarm for a period of time determined by the patient movement data; and
wherein the alarm is a respiration rate alarm.

### Claim 5 (depends on 1)

The patient monitoring and support system according to claim 1, the memory further storing instructions that, when executed by the processing unit, cause the control module to, upon determining that the patient is at risk for aspiration, automatically adjusting a head of bed angle to at least 25 degrees.

### Claim 6 (depends on 1)

The patient monitoring and support system according to claim 1, the memory further storing instructions that, when executed by the processing unit, cause the control module to, upon determining that the patient is at risk for aspiration, transmit a clinician notification, the clinician notification including a recommendation for adjusting a head of bed angle to at least 25 degrees.

### Claim 7 (depends on 1)

The patient monitoring and support system according to claim 1, the memory further storing instructions that, when executed by the processing unit, cause the control module to authenticate a physiological sensor device.

### Claim 8 (depends on 7)

The patient monitoring and support system according to claim 7, the patient monitoring and support system defining a sensor receiving cavity sized to receive the physiological sensor device, the sensor receiving cavity including a magnet.

### Claim 9 (depends on 8)

The patient monitoring and support system according to claim 8, the sensor receiving cavity including a wireless charging module configured to provide power to the physiological sensor device.

### Claim 10 (depends on 9)

The patient monitoring and support system according to claim 9, the sensor receiving cavity including a data communication module configured to enable data transmission between the physiological sensor device and the patient monitoring and support system.

### Claim 11 (depends on 1)

The patient monitoring and support system according to claim 1, wherein the patient status data includes pharmacological data, and wherein the control module is configured to further adjust the alarm limits when the pharmacological data predicts a change in the patient status data.
